Family - Polygalaceae
Stems - Multiple from a thickened taproot and fibrous roots, erect, herbaceous, to +45cm tall, branching in upper 1/2, often purplish base, puberulent above, glabrescent at base, terete.
Leaves - Alternate, petiolate. Petioles to 2-3mm long, puberulent below. Blades acuminate, tapering at base, elliptic, deep green above, lighter green below, with serrulate margins, mostly glabrous but with a very few sparse puberulent hairs, to 7cm long, +2.5cm broad, leaves often larger near the apex of the plant.
Inflorescence - Terminal and lateral indeterminate racemes to +/-5cm tall (long). Axis puberulent.
Flowers - Petals 3, united into a whitish glabrous tube, lacerate at apex. Stamens 8, adnate with corolla tube, in two rows. Anthers yellow, .2mm long. Ovary superior, green, glabrous, orbicular, .7mm in diameter. Style green, -1mm long, green, glabrous, with a few floccose hairs at apex, clavate. Stigma lateral, small. Calyx accrescent. Sepals 5. Lateral sepals colored as the petals and spreading, to +3mm long, 2.1mm broad, glabrous, with ciliolate margins. Lower two sepals and single upper sepal small, greenish-white, acute, puberulent. Lower two to .3mm long. The basal sepal to 1.5mm long. Fruit a capsule, glabrous to sparse pubescent, to 5mm in diameter, slightly compressed.
Flowering - May - July.
Habitat - Rocky woods, open ground, prairies, gravel bars, stream banks.
Origin - Native to U.S.
Other info. - This small species can be found in a couple different areas of Missouri. It is more prevalent in the Ozark region but can also be found in a few counties in the north-central portion of the state. This is a striking little plant and should be cultivated more.
Steyermark lists two varieties based on leaf shape and sepal size but I won't go into those here.

アンゲロニアの育て方・栽培方法
育て方のポイント
栽培環境・日当たり・置き場
最低でも1日のうち2～3時間は日が当たり、少し湿り気のある場所に植えつけましょう。しかし、水はけの悪い場所に植えつける場合は、盛り土したり、腐葉土を混合して水はけをよくしてから植えつけます。やせた土地では、あらかじめ完熟堆肥を入れ混ぜてから植えつけます。
水やり
鉢植えでは、鉢土の表面が乾いてきたら、たっぷり水を与えましょう。庭植えでは、真夏に晴れが続き、乾くようなら水を与えましょう。
肥料
鉢植えには6月から10月に、緩効性化成肥料（チッ素N-リン酸P-カリK=10-10-10）と液体肥料（N-P-K=6-10-5）を併用して施します。庭植えでは6月から10月に、緩効性化成肥料（N-P-K=10-10-10）を施します。
病気と害虫
病気：灰色かび病
6月から7月と9月から10月に雨が続くと、灰色かび病が発生しやすくなります。風通しをよくすると、発生を抑えることができます。
害虫：アブラムシ、ナメクジ
5月から10月の間、アブラムシが特に新芽に発生しやすいのでよく観察し、発生したら防除します。
6月から7月の梅雨どきに、ナメクジの発生が多くなります。昼間は鉢の底や石の下などに潜んでいて、夜に這い出して植物を食害するので、夜に見回って捕殺しましょう。
用土（鉢植え）
水はけがよく保水力のある土を好みます。赤玉土（中粒）5、腐葉土3、酸度調整済みピートモス2の配合土などを用います。元肥として、リン酸分の多い緩効性化成肥料を適量混ぜて植えつけましょう。
植えつけ、 植え替え
5月から7月が植えつけ適期です。品種によって草丈が違うので、用途に合わせて品種を選びましょう。
ふやし方
タネまき：5月から6月にタネをまき、ふやすことができます。高温を好むので、早まきは避けましょう。
主な作業
切り戻し：摘まなくても花がらは勝手に落ちますが、葉の上などに花がらが残っていると病気の原因になるので、取り除きます。7月から8月ごろ、花が咲き終わった花茎が目立つようになったら、わき芽の上で1/2～2/3の草丈になるように切り戻すとわき芽が伸び、さらに多くの花をつけます。
支柱立て：高性品種は倒れやすいので、6月から10月ごろ、適宜支柱を立てておきましょう。

Family - Orobanchaceae
Stems - Parasitic on roots of other vascular plants, herbaceous, achlorophyllous, subterranean, thin, glabrous.
Leaves - Alternate, few, reduced to scales, whitish-tan, 2-3mm long, glabrous, ovate.
Inflorescence - Solitary flower on axillary pedicel to 15cm long. Pedicel glandular pubescent, erect.
Flower - Corolla typically white, tubular, 2.2cm long, dense glandular pubescent, 5-lobed. Lobes to 6mm long, 4.5mm broad, with two yellow bearded strips alternating with two bottom lobes. Stamens 4, adnate at base of corolla tube, alternating with lobes. Filaments white, glabrous, to +4mm long. Anthers pale yellow, 1.1mm long. Style 7-8mm long, glabrous, tubular, expanded at apex. Stigma two lobed. Calyx tube campanulate, 5-lobed. Tube to 4mm long, 5-6mm in diameter, dense glandular pubescent. Lobes attenuate, to 5mm long, glandular pubescent.
Flowering - April - June.
Habitat - Wooded slopes, rocky open woods, rocky glades, base of bluffs.
Origin - Native to U.S.
Other info. - I like the parasitic plants and this plant is no exception. It's a small plant but easy to find because of the fairly large white flower. The big tubular corolla with the yellow bearded strips is just screaming to be visited by a bee or small wasp. The stems are short and thin and rarely seen unless you dig a bit at the base of the pedicel.

Family - Orchidaceae
Stems - Flowering stem to +/-15cm tall, from rhizomes and thick roots, glabrous, simple, herbaceous, erect.
Leaves - Basal, typically 2, elliptic to spatulate or obovate, entire, subsucculent, glabrous, shiny green, tapering to base, rounded at apex, to +7cm broad, +15cm long, sheathing at base. Leaves of flowering stem reduced to foliaceous bracts, lance-oblong, to +4cm long, 2cm broad, entire, glabrous.
Inflorescence - Terminal raceme with +/-5 flowers. Each flower subtended by single foliaceous bract. Bracts sessile.
Flowers - Corolla white to pink and white, to +3cm long, resupinate. Sepals to +1.5cm long, 5mm broad, lanceolate, typically pink but also white, glabrous, forming a hood around the column. Lateral petals linear, to 1.5cm long, 4mm broad, forming hood with sepals. "Lower" petal (lip) to +1.5cm long, +1.2cm broad, (sub)acute at apex, white, glabrous, ovate, with undulate margins, spurred. Spur to +1.5cm long, expanded slightly at apex (clavate). Column to 8mm long, whitish. Stamen 1. Ovary inferior. Capsules to 2cm long, erect, many seeded.
Flowering - April - June.
Habitat - Ravines, rich and low woods.
Origin - Native to U.S.
Other info. - This striking little plant is common throughout Missouri but is often not seen by the casual observer because it grows in deep woods and ravines. The flowers are typically white and pink but can be all white also. The flowers are also resupinate so what looks like the top of the flower is actually the bottom and vice versa. The big lip of the corolla is a perfect landing platform for flying insects, the plants main pollinators.
A common synonym is Galearis spectabilis (L.) Raf.

Family - Campanulaceae
Stems - Simple, erect, to +/-50cm tall, glabrous to variously pubescent, herbaceous, 4-5 angled.
Leaves - Mostly in lower 1/2 of stem, sessile or short petiolate (near base of stem), spatulate to oblong, rounded at apex, entire to irregularly dentate (margins strigillose to ciliate), +/-5cm long, +/-2cm broad, sparse strigose to glabrous.
Inflorescence - Terminal spikiform raceme to +/-35cm long (tall). Each flower subtended by a lance-linear to subulate bract to 1.5cm long, 3mm broad. Bracts typically glabrous. Pedicels to 3mm long, glabrous to pubescent.
Flowers - Resupinate. Corolla whitish to lilac, to 1.3mm long, 5-lobed. Three "upper" lobes to 4.1mm long, 2mm broad, oblanceolate to lanceolate. Two "lower" lobes deflexed to reflexed, 3mm long. Stamens 5, adnate at base of corolla tube. Filaments white, pubescent at base. Anthers purplish-blue, connate around stigma. Stigma purple, bearded at base. Style 1, 5mm long, glabrous, greenish. Ovary ovoid-conic, slightly compressed, green, 2-locular. Placentation axile. Calyx tube +/-1mm long, 5-lobed. Lobes auricled at base, 3mm long, -1mm broad at base, linear-attenuate. Auricles various. Capsule to 8mm long, +/-4mm in diameter, glabrous to pubescent.
Flowering - May - August.
Habitat - Prairies, glades, open woods, bluffs, wet meadows.
Origin - Native to U.S.
Other info. - This is a highly variable species. The flowers can be bluish to white, the stems can be glabrous to hispid, and the calyx lobes can have variable auricles at their bases. The anthers of the plant can also be variable in color sometimes. Steyermark breaks the species apart into 4 different varieties but these varieties integrade and can be difficult to distinguish so I won't mention them here.
Remember, the flowers are inverted (resupinate) on this plant so what looks like the top of the flower is actually the bottom and vice-versa.

Family - Campanulaceae
Stems - To 2.2m tall, angled, hairy on angles or not.
Leaves - Alternate, 2-6cm broad, to 15cm long, typically with pubescence on both surfaces - but not always, with some teeth on margins, sessile or on very short petioles, oblong to lanceolate.
Inflorescence - Terminal and axillary racemes, with at least 20 flowers but usually many more.
Flowers - Perianth to +/- 3cm long. Corolla white, tubular, with five lobes - two on upper portion, three below.
Flowering - August - October.
Habitat - Moist to wet soils.
Origin - Native to U.S.
Other info. - This plant appears to grow taller than typical L. siphilitica with blue-purple flowers. It is quite striking and I was pleased to find it growing wild at the zoo (just this one plant), since it is uncommon in this state. This is the only time I have seen this plant.
Don't confuse this plant with L. spicata which has much smaller flowers and is a generally smaller plant.

Satminate flowers - Pedicel stellate pubescent, 1.2mm long, each flower subtended by a small needlelike bract. Bracts to 1mm long. Numerous glands present at the base of each pedicel. Pistillate flowers - Pedicel to .1 or .2mm long.
Flowers - Staminate flowers - Petals 5, all white, stellate pubescent, slightly exceeding the sepals, oblong-lanceolate. Stamens 10. Filaments white, glabrous, to 1.5mm long. Anthers pale yellow, .4mm broad. Sepals 5, ovate, to 1.2mm long, white, stellate pubescent. Pistillate flowers - Sepals 5, greenish, stellate pubescent externally (branches of the pubescence long and thin), glabrous internally, +/-2mm long in flower, accrescent, oblanceolate to spatulate. Ovary stellate pubescent, green, superior, 1mm long in flower, 3-locular (one seed per locule). Placentation axile. Styles 3, divided nearly to the base and appearing as 6, white, papillate, 2.2mm long.
Flowering - July - October.
Habitat - Prairies, open woods, waste ground, pastures, glades, roadsides, railroads.
Origin - Native to U.S.
Other info. - This species is found throughout most of Missouri but seems to be absent from the north-central portion of the state. This species is easy to ID because of its toothed leaves. No other wild species of Croton in Missouri has toothed leaves. The species epithet comes from the fact that the leaves typically have two glands at the base of each leaf blade.

Other info. - This species can be found sporadically escaped throughout much of Missouri. The plant is often found around old homesites or businesses.
C. majalis can form large colonies when left untouched. It is a toxic plant that contains cardiac glycosides.
Traditionally the plant was used as a Digitalis substitute to treat heart disease. A flower and root tea was used to treat fevers, as a diuretic, sedative, and emetic. A root ointment was used to treat burns to prevent scaring.
Stems - Creeping underground rhizomes. Aerial stems to +15cm long.
Leaves - 2-3 per node, oblong to elliptic, entire, glabrous, to +15cm long, +4cm broad.
Inflorescence - Raceme terminating aerial stem, to 7cm long. Pedicels to 1cm long, glabrous, with scarious bract at base to 8mm long.
Flowers - Nodding. Perianth campanulate, white, glabrous, to +6mm long, +8mm broad, 6-lobed. Lobes 2.5mm broad, 3mm long, fragrant. Stamens 6, borne at base of perianth tube. Anthers pale yellow, to 2mm long, tapering to point at apex. Filaments short, -1.5mm long, pinkish-purple at base. Ovary glabrous, superior, 3-carpellate. Style 2.2mm long.
Fruit - Globose, red, fleshy, to -1cm in diameter.
Flowering - April - May.

Family - Apiaceae
Stems - To -2m tall, erect, herbaceous, glabrous, glaucous, fistulose, purplish at nodes, typically simple to branching, from a tuberous base and fleshy roots, single or multiple from base.
Leaves - Alternate, 2-3-pinnate. Lowest leaves long petiolate, to +60cm long(including petiole). Upper leaves with shorter petioles. Petioles with involute margin. Leaf divisions purple at axils. Ultimate leaflets serrate(the teeth mucronate), lanceolate, glabrous.
Inflorescence - Axillary and terminal compound umbels. Main rays of umbels not subtended by bracts, to -3cm long(in flower), +/-15 in number. Secondary rays(raylets) 5-6cm long(in flower), subtended by bracts. Bracts with scarious margins, to 3mm long, attenuate-lanceolate, glabrous.
Flowers - Petals 5, white, unequal to subequal, margins deflexed, to 1.3mm broad, 1.1mm long, apiculate and inflexed at apex. Stamens 5, alternating with petals, erect to spreading. Filaments white, 1.2mm long, glabrous. Anthers whitish, .2mm long. Ovary inferior, 2-locular. Styles 2, .1mm long. Calyx tube .9mm long, glabrous, 5-lobed. Lobes acute, scarious, .4-.5mm long. Fruits to +4mm long, oval to orbicular, glabrous.
Flowering - May - September.
Habitat - Wet to moist areas.
Origin - Native to U.S.
Other info. - This plant is one of the more toxic species of the Apiaceae or of any plant family for that matter. The plant has a pleasant licorice or anise scent when crushed but obviously it should not be eaten. It is easy to ID in the field because of its habitat, its glabrous and glaucous stems (which are purplish at the nodes), and its 2-3-pinnately divided leaves.
The Missouri plants are all variety maculata. A couple of other varieties are found in the U.S. but not in Missouri. The plant is common throughout Missouri.

Family - Brassicaceae
Stems - To +40cm tall, erect, herbaceous, terete, hispidulous (mainly in the basal half), green, purplish at the base, simple to 1-2 branched in the apical half, from a short knotty rhizome.
Leaves - Alternate, petiolate below, becoming sessile above. Basal leaves on petioles to +8cm long. Petioles glabrous to hipidulous, flattened. Blades reniform to broadly ovate, glabrous, with wavy margins, +5cm long and broad. Cauline leaves becoming sessile or short petiolate, few (1-5), ovate to lanceolate, with a few coarse teeth, glabrous, light green below (abaxially), deep dull green above, with sparse ciliolate margins or not.
Flowers - Flowers not seen. Siliques to 3cm long, 2cm broad, glabrous, with a beak to 4mm long, 2-valved, with a small constriction between the seeds.
Flowering - March - April.
Habitat - Low or swampy woodlands.
Origin - Native to U.S.
Other info. - This attractive species can be found mainly in the northern half of Missouri in a handful of counties. The plant can be identified by its reniform basal leaf blades, few, sessile or nearly sessile cauline leaves, and big flowers. The flowers are typically purple but the plants photographed in Columbia, MO., had white flowers.
