Regarding Vernona baldwinii and V. interior, L. H. Shinners (1950) wrote, "The tips of the phyllaries vary from loosely appressed to squarrose, and from puberulent to almost completely glabrous on the inner face. The geographic distribution of the two extremes is nearly identical. I consider the two to be merely forms of one species." I concur.

Vernonia baldwinii

provided by wikipedia EN

Vernonia baldwinii, commonly known as western ironweed[1] or Baldwin's ironweed,[2] is a perennial herb native to the central United States.[3] It is in the Asteraceae (aster) family.

Description

Vernonia baldwinii is a tall, perennial herb with rhizomes. Its stems are densely tomentose, branched, round in cross section, and range up to 1.2 m (3 ft 11 in) in height, sometimes taller. Its leaves are lanceolate, cauline and alternate, and are about 15 cm (5.9 in) in length and 4.5 cm (1.8 in) in width.[4] The larger leaves have serrated edges.[5] The upper surface of the leaves is minutely hairy, and the lower surface has longer, often bent or tangled hairs.[1]

The inflorescence is showy and somewhat flat-topped, consisting of irregularly branched terminal panicles, and measures 30 cm (1 ft) or more across. Flowerheads have 17 to 34 disk flowers only, with no ray flowers. The corollas on the disk flowers are deep pink to purple, 5-lobed, glabrous, and 0.3–0.4 in (8–10 mm) long. [5][1]

Taxonomy

The genus Vernonia is named for the English botanist William Vernon, and the species baldwinii is named for William Baldwin, the American botanist and physician who collected the plant.[6]

The common name "western ironweed" is derived from the range of the plant, the western United States, and derived from the toughness of the stem and roots of the plant.[6]

Distribution and habitat

It grows in dry soil in prairies, pastures, open grounds, and woods, ranging from Iowa to Missouri, Nebraska, Kansas, and Texas.[7]

Ecology

The flowers bloom in the summer, from May to September, attracting bees, butterflies, and other insects. American goldfinches and other birds eat the seeds.[8]
