Description: This herbaceous perennial plant is about 1-2½' tall, branching occasionally. The stems are light green to reddish purple, terete, and glabrous (var. longistylis) to hairy (var. villicaulis). The alternate leaves are ternately compound; the lower compound leaves are up to 9" long and 9" across, while the upper compound leaves are much smaller in size. Each compound leaf is divided into 3 compound leaflets; the terminal compound leaflet is the largest. Each compound leaflet is further divided into 3 subleaflets; the terminal subleaflet is the largest, sometimes appearing to be divided into 3 even smaller subleaflets. The subleaflets are 1-4" long, ½-1½" across, and lanceolate to oval-ovate shape in shape; their margins are coarsely serrated-crenate or shallowly cleft. The upper subleaflet surface is yellowish green to green and nearly glabrous (var. longistylis) to moderately covered with appressed hairs (var. villicaulis). The petioles of compound leaves are light green to reddish purple and up to 6" in length. The petiolules of leaflets are light green to reddish green and up to 2" long, while those of subleaflets are nearly sessile to ¼" (6 mm.) long. The foliage of this plant releases a mild anise fragrance when it is rubbed. The upper stems terminate in compound umbels of white flowers about 1½-3" across. There are about 3-6 umbellets per compound umbel on rays (floral stalks) up to 2" long. An umbellet has 7-16 flowers that are clustered together on rays (floral stalklets) up to ¼" (6 mm.) long. Each flower (about 3 mm. across) has 5 white petals with incurved tips, 5 white stamens, a pistil with a divided white style (stylopodium), and an insignificant calyx that is light green. At the base of each compound umbel, there are several linear-lanceolate bracts with ciliate margins; they are up to 8 mm. in length. At the base of each umbellet, there are several linear-lanceolate bractlets with ciliate margins; they are also up to 8 mm. in length. [图片]The blooming period occurs during the late spring or early summer, lasting about 2-3 weeks. Afterwards, the flowers are replaced by 2-seeded fruits (schizocarps). While these fruits are still immature, the persistent divided style is 2.0-3.5 mm. in length (it is smaller than this when the flowers are still in bloom). The small seeds are narrowly ellipsoid-oblanceoloid, 5-ribbed, and slightly bristly along their ribs. The root system consists of a cluster of fleshy roots with a strong anise fragrance. Cultivation: The preference is dappled sunlight to moderate shade, moist to mesic conditions, and rich loamy soil with decaying organic matter. In a garden situation, this plant will probably thrive in a sheltered area underneath a deciduous tree. [图片]Range & Habitat: The native Aniseroot occurs in most counties of central and northern Illinois, where it is occasional to locally common; in southern Illinois, it is uncommon or absent (see Distribution Map). This map combines information for both varieties of Aniseroot; the typical variety is slightly more common than the hairy variety (var. villicaulis). Habitats include moist to mesic deciduous woodlands and gentle slopes of wooded ravines, where a variety of deciduous trees are dominant. Aniseroot can be found in average to high quality natural areas. [图片]Faunal Associations: The nectar and pollen of the flowers attract small to medium-sized bees, wasps, beetles, and flies, including cuckoo bees (Nomada spp.), mason bees (Osmia spp.), Halictid bees (Agapostemon spp., Augochloropsis spp., Halictus spp., Lasioglossum spp.), masked bees (Hylaeus spp.), Syrphid flies, bee flies (Bombyliidae), dance flies (Empis spp.), Tachinid flies, and Anthomyiid flies. The caterpillars of the butterfly Papilio polyxenes asturias (Black Swallowtail) feed on the foliage. The slightly bristly seeds may cling to the fur of mammals, the feathers of birds, and the clothing of humans to some extent, dispersing them to new locations. Photographic Location: A mesic deciduous woodland at Busey Woods in Urbana, Illinois. [图片]Comments: Aniseroot (Osmorhiza longistylis) can be distinguished from many similar species in the Carrot family by the anise fragance of its foliage and roots. This species closely resembles Sweet Cicely (Osmorhiza claytonii) and they are often confused with each other. However, Sweet Cicely has only 4-7 flowers per umbellet, while Aniseroot has 7-16 flowers per umbellet. While the fruits of these two species are still immature, the persistent styles of Sweet Cicely are 1.0-2.0 mm. in length, while the persistent styles of Aniseroot are 2.0-3.5 mm. in length. The foliage and roots of Aniseroot have a stronger anise scent than those of Sweet Cicely, and its root can be used as a substitute for black licorice.

Colony of Flowering PlantsDescription: This wildflower is a perennial, producing 1-5 erect flowering stalks about 3-8" tall. The flowering stalks are produced by a scaly short stem that is 1" or less in length; this stem is usually underground and only the flowering stalks are visible above ground. The short scales along the stem are highly modified leaves; they are oval to ovate in shape and somewhat thick and succulent. The flowering stalks are usually pale gray or grayish tan, terete, and hairy. At the apex, each stalk produces a single nodding flower about ¾–1" long. This flower has a tubular corolla with 5 spreading lobes and a short hairy calyx with 5 lanceolate teeth; the teeth usually have slender tips. The coloration of the calyx is usually similar to the flowering stalk. The corolla is white to lilac or a blending of these two colors (rarely is it purple, at least in the Midwest); it is covered with short fine hairs. Along the lower throat of the corolla, there is usually a patch of bright yellow hairs, although sometimes these hairs are cream-colored or white. Inserted within the corolla, there is an ovary with a single style and 4 stamens. The blooming period occurs from late spring to early summer and lasts about 2-4 weeks. In the absence of cross-pollination by insects, the flowers are self-fertile. Each flower is replaced by an ovoid seed capsule, that splits open to release minute seeds. These seeds are small enough to be blown about by the wind and they eventually sink into the crevices of the soil and ground litter. The root system is parasitic, developing feeder roots (haustoria) that attach themselves to the roots of a suitable host plant. One-Flowered Broomrape is holoparasitic and lacks chlorophyll; it is dependent on the host plant for nutrients. Cultivation: This wildflower is often found in moist rocky areas where there is some protection from the wind. However, it is also found in non-rocky soil. The presence of a suitable host plant is required before the seeds will germinate. The seeds germinate in response to the presence of chemicals in the soil that the developing host plant produces. In addition, a suitable fungus may be necessary to function as an intermediary between the seedling and host plant. Suitable host plants include Sedum spp. (Sedums), upland Saxifraga spp. (Saxifrage), Helianthus spp. (Sunflowers), Solidago spp. (Goldenrods), and probably other plant species. Transplanted specimens of One-Flowered Broomrape are unlikely to survive for very long. Range & Habitat: One-Flowered Broomrape is occasional in Illinois, except in the SE section, where it is rare or absent. This is the most common Orobanche sp. (Broomrape) in the state; it is native. Habitats include upland woodlands, rocky cliffs where some seepage occurs, the base of bluffs, rocky glades, and thickets. This species is usually found in high quality natural areas. Faunal Associations: The flowers are cross-pollinated by bumblebees and possibly other long-tongued bees. Charles Robertson (1929) observed the bumblebee, Bombus pensylvanicus, visiting the flowers for nectar. Aside from this observation, very little appears to be known about floral-faunal relationships for this species. Photographic Location: The photograph (Copyright © 2009) of Orobanche uniflora was taken by Lisa Culp in a wooded area of Somme Prairie Grove Nature Preserve in Cook County, Illinois. Comments: This unusual wildflower has a reputation of appearing unexpectedly in one area, only to disappear and reappear in another area of the same habitat. Most likely, this intermittent pattern results from the underground stems producing flowering stalks during some years, but not others. Unlike some other species in this genus, One-Flowered Broomrape produces only a single flower per stalk, rather than a spike-like stalk with multiple flowers. Only one other species in Illinois, Orobanche fasciculata (Clustered Broomrape), shares this characteristic. Clustered Broomrape has a longer scaly stem (2-4") that is also underground, from which 4-12 flowering stalks develop above ground. There is a tendency for the lobes of its flowers to be less spreading or more divided into 2 lips; One-Flowered Broomrape has flowers with spreading lobes and poorly defined upper and lower lips. The common name of this genus, 'Broomrape,' derives from an Orobanche sp. in Europe that is parasitic on Broom (Cytisus sp.) as a host plant. Other common names of Orobanche uniflora are 'Naked Broomrape' and 'Ghost Pipes.'

Description: This wildflower is a winter annual or biennial about ½–1½' tall that is unbranched or branches occasionally. The stems are light green, terete or angular, and covered with long white hairs. The alternate leaves are ½–2" long and about one-third as wide; they are light green, oblong or oblanceolate, smooth and ciliate along the margins, and usually hairy on both the upper and lower surfaces. Each leaf has aFlowers & Upper Leaves prominent central vein. The leaves are mostly sessile against their stems; the lowest leaves taper to petiole-like bases. The central stem and upper lateral stems (if present) terminate in elongated racemes of small white flowers about 2-8" long. Each raceme has about 8-24 flowers on a hairy stalk; there are no bracts alongside the flowers. The flowers bloom toward the apex of each raceme, where it is typically curled like a scorpion's tail; the hairy ovoid fruits develop below. Each flower is 1/8" across, consisting of a white corolla with 5 rounded lobes, a hairy calyx with 5 lanceolate sepals, 5 stamens (inconspicuous), and a pistil. Sometimes the hairs of the calyx are hooked at their tips. The blooming period occurs from mid-spring to early summer and lasts about 2 months. The racemes become longer as their dry fruits (seed capsules) develop; these fruits have pedicels that are more or less erect. At this stage of development, the pedicels are a little shorter than their fruits. Each fruit contains 4 seeds. The root system consists of a taproot and secondary fibrous roots. This wildflower reproduces by reseeding itself. Cultivation: The preference is full sun to light shade, moist to dry conditions, and barren soil containing sand, gravel, or clay. Most growth and development occurs during the spring. Range & Habitat: The native Spring Scorpion Grass is occasional to locally common in the southern half of Illinois, while in the northern half of the state it is uncommon or absent (see Distribution Map). Habitats include upland open woodlands, barren wooded slopes, areas along woodland paths, sandy savannas, sand prairies, fields, roadside embankments, and areas along railroads. This little wildflower occurs in barren areas where there is little ground vegetation – frequently where there is some history of disturbance. Occasionally, it is found in damp areas. Faunal Associations: Small bees and small butterflies visit the flowers for nectar. Robertson (1929) observed only two floral visitors: the Halictid bee Augochlorella striata and the butterfly Pontia protodice (Checkered White). The flea beetle Longitarsus melanurus feeds on the foliage of Spring Scorpion Grass and other species in the Borage family. LeConte's Sparrow and possibly other birds eat the seeds of this wildflower and the closely related Myosotis macrosperma (Big-Seeded Scorpion Grass); this was observed at Tucker's Prairie in Missouri. The hairy fruits can cling to the fur of mammals and clothing of humans; this helps to distribute the seeds to new locations. [图片]Photographic Location: A wooded slope near Charleston, Illinois. Comments: This wildflower has small flowers and is fairly easy to overlook. In spite of its common name, Spring Scorpion Grass is a member of the Borage family, rather than the Grass family (Poaceae). This species is very similar to Myosotis macrosperma (Big-Seeded Scorpion Grass); sometimes they are considered different varieties of the same species. According to Mohlenbrock (2002), Spring Scorpion Grass has fruits with more erect pedicels and smaller seeds than Big-Fruited Scorpion Grass; in Illinois, the latter is restricted to a few southern counties. Another similar species is Buglossoides arvense (Corn Gromwell). Corn Gromwell has leafy bracts alongside its flowers, while the flowers of Spring Scorpion Grass (and other Myosotis spp.) lack such bracts. There are also several Myosotis spp. (Forget-Me-Not species) from Europe that occasionally escape from cultivation. These introduced species have blue flowers. Another common name of Myosotis verna is White Forget-Me-Not.

Description: This perennial wildflower typically consists of a cluster of unbranched erect stems about 3-9" tall. These stems are terete, white (sometimes tinted pink), translucent, fleshy, and hairless. The alternate leaves are scale-like and small; like the stems, they are white, translucent, and hairless. Each stem terminates in a single white flower about ½–¾" long that is nodding to nearly erect; this flower is narrowly bell-shaped, consisting of 2-4 sepals and 4-5 petals. The petals are longer and more persistent than the sepals. Within the interior of the flower, there are 10-12 stamens surrounding a stout style. The time of year when flowers are produced can be highly variable, extending from late spring into the fall. However, the blooming period for individual plants lasts only 1-2 weeks. The flowers produce no obvious floral scent. After the blooming period, the entire plant becomes dark brown or black, and each flower is replaced by an erect ovoid seed capsule about ½" long. This seed capsule is 5-celled and contains numerous tiny seeds, which are easily blown about by the wind after the capsule splits open. The root system consists of a mat of brittle fleshy roots. This wildflower is saprophytic and lacks chlorophyll in its tissues; it forms either a symbiotic or parasitic association with mycorrhizal fungi through its roots. Cultivation: Cultivating Indian Pipe is very difficult, if not impossible; plants that are transplanted from the wild are highly unlikely to survive. Abundant woodland humus and the presence of appropriate fungi are required for survival. Because Indian Pipe does not rely on photosynthesis, it can adapt to deep shade. Range & Habitat: Indian Pipe can be found at scattered sites throughout Illinois (see Distribution Map). In Illinois, habitats are largely restricted to rich deciduous woodlands in areas with abundant humus. These woodlands are typically dominated by either maples or oaks. Indian Pipe also occurs in woodlands where coniferous trees are present. This unusual wildflower is normally found in high quality woodlands. Faunal Associations: Information about floral-faunal relationships for this species is very limited. The flowers are cross-pollinated by long-tongued bees; such insects probably seek nectar. Bears may feed on the plants when they develop above the ground surface, or they may dig up and feed on the root mass (the latter behavior has been observed for Grizzly Bears in British Columbia). Indian Pipe is not known to be toxic. [图片]Photographic Location: The photographs (Copyright © 2008) were taken by Paul and London Showers near Wilmot Woods in Lake County, Illinois. Comments: Because of its ghostly white appearance, some people may confuse Indian Pipe for a fungus. This species belongs to a small group of saprophytic flowering plants that have abandoned photosynthesis. A similar species, Monotropa hypopithys (Pinesap), also occurs in Illinois, but it is less common. Unlike Indian Pipe, Pinesap produces several nodding flowers on each stem; these flowers are arranged in a short raceme. Pinesap is more likely to be tinted different colors (including bright red), and it is often pubescent.
