Family - Asteraceae
Stems - To 1m tall, glabrous to hispidulous, single from the base, typically simple in the lower 1/2, terete, erect, herbaceous.
Leaves - Alternate. Basal leaves long petiolate, the petiole to +15cm long. Blades of basal leaves cordate to truncate or abruptly narrowed at base, very scabrous above and below, to 10cm long, 7cm wide. Middle and upper cauline leaves greatly reduced as compared to basal leaves, 2-10mm broad, sessile, appearing as linear bracts near inflorescence.
Inflorescence - Loosely paniculate, open, many flowered(+75) but the flowers opening at different times.
Involucre - 4.5-7mm tall (long), cylindric. Phyllaries imbricate, lanceolate, appressed, mostly whitish with distinct rhombic green tips, margins minutely ciliolate.
Ray flowers - Ligules blue, to 9mm long, typically +/- 15 per flower head.
Disk flowers - Disk 4-5mm broad. Corollas yellow, small, 15-30 per head. Achenes glabrous, +/-1mm long. Pappus of capillary bristles, +2.5mm long.
Flowering - September - October.
Habitat - Open woods, prairies, pastures, glades, roadsides.
Origin - Native to U.S.
Other info. - This little but showy species can be found scattered throughout much of Missouri. Steyermark wrote, however, that it is found in less than half the counties in the state.
The plant is easy to identify because of its leaves, which are very scabrous - almost like sandpaper. The small blue flowers and green diamond-tipped phyllaries help also. Plants with glabrous stems can be growing right next to those with hispidulous stems so stem pubescence is NOT a good character to use for identification.

Family - Asteraceae
Stems - To -1m tall, erect, herbaceous, terete, from a slightly elongated woody caudex and slightly thickened roots, puberulent (the trichomes multicellular), somewhat scabrous, green, typically simple at the base, widely branching in the apical 1/2 (the inflorescence).
Leaves - Alternate, petiolate. Basal rosette leaves similar to cauline leaves. Petioles to +/-4cm long, puberulent as the stem, narrowly winged by decurrent blade tissue. Wings 1mm or less broad, forming an adaxial groove on the petiole. Blades ovate to lanceolate, cordate to truncate at the base, entire or with a few coarse teeth, attenuate, to 8-9cm long, 3-4cm broad, slightly reduced upward. Leaves in inflorescence reduced to linear bracts and typically somewhat recurved. Blades soft puberulent, more so abaxially (again with multicellular trichomes).
Inflorescence - Single flower heads terminating branches of the inflorescence. Flowers of the inflorescence typically open and sparse but sometimes dense as seen below:
Involucre - Cylindric, 7-8mm long (tall), 5-7mm in diameter. Phyllaries imbricate, linear, strongly recurved, puberulent, 5-8mm long, +/-1mm broad, green, with a callous translucent bristle tip. Tip to .4mm long.
Ray flowers - +/-23 per head, fertile, pistillate. Corolla tube to 4mm long, white, mostly glabrous externally or with a few appressed hairs. Ligule lilac, +/-1.6cm long, -3mm broad, glabrous or with a few appressed hairs at the base abaxially. Style white, glabrous, +/-5mm long, yellow at the apex, bifurcate. Stigmas to 1.2mm long. Pappus of numerous capillary bristles. Bristles white, antrorse barbellate, +/-4mm long.
Disk flowers - Disk 5-6mm broad. Corollas 5-6mm long, contracted and white in the basal 1/2, expanded and yellow in upper 1/2, glabrous inside and out, 5-lobed. Lobes acute, spreading, .7mm long. Stamens 5, adnate at the apex of the constricted portion of the corolla tube. Filaments translucent, +/-2mm long, terete. Anthers yellow, 1.3mm long, partially to entirely exserted, connate around the style. Style white, terete, glabrous, 5-6mm long. Stigmas yellow, 1mm long, not spreading, pubescent at the apex. Achenes of rays broader than those of disk flowers, glabrous, white, compressed, with 5 thick and evident veins (ribs). Receptacle flat, naked.
Flowering - July - November.
Habitat - Dry and rocky open woods, thickets, roadsides. Typically on acid soils.
Origin - Native to U.S.
Other info. - This showy species is one of the most common blue-flowered Asters in the Ozark region and in Missouri. The plant can be seen in profusion along roadsides through the Ozarks and is found in nearly all the upland wooded habitats there. It is, however, absent from the extreme southeast and northwest corners of the state.
This species can be differentiated from the other blue-flowered Asters because of its soft pubescent leaves and recurved phyllaries. The leaves of other species have a scratchy texture to them. A. anomalus has just about the softest leaves of them all. If you are in doubt about which cordate-leaved Aster you are looking at, just remember - "There is nothing softer than anomalus." The narrowly-winged petioles also help to ID this species. Other similar Asters have much broader wings on their petioles.

Inflorescence - Single axillary flowers. Peduncles typically shorter than leaves, to +4cm long, 1.1mm in diameter, glabrous.
Flowers - Corolla to 5cm broad, slaverform. Corolla tube to +/-1.5cm long, contracted near base, glabrous, 5-lobed. Lobes spreading, to 2cm long, 1.8cm broad, purple with white at base, glabrous, truncate at apex. Stamens 5, adnate to corolla tube, included. Anthers converging, with expanded connective that covers the stigma. Style 1, included. Ovary 2-carpellate. Calyx tube to 2mm long and broad, 5-lobed. Lobes linear-attenuate, to 1.5cm long, 1.1mm broad at base, ciliate-margined. Follicles 2, fused, to 5cm long.
Flowering - April - May.
Habitat - Cultivated.
Origin - Native to Europe.
Other info. - When speaking of this plant is very important that everyone is using scientific name to prevent confusion. The name Vinca is, unfortunately, used by some folks as a name for another member of the Apocynaceae, Catharanthus roseus. The term "Periwinkle" is often used to name both Vinca and Catharanthus. To make matters worse there is another species of Vinca, Vinca minor, which also grows in Missouri. If there were ever a better argument for using only scientific names, I do not know it.
V. major is not as common in this state as the closely related V. minor. The two plants are nearly identical except for leaf shape and flower size.
