Desmodium glabellum (Dillenius' ticktrefoil[3] or tall tick-trefoil) is a perennial herb and wildflower in the pea family native to eastern and central North America. It grows in fields, woodland borders, and disturbed areas.[4]
Description
Desmodium glabellum grows to 5 feet tall with alternate palmately trifoliate leaves. Light pink to purplish flowers appear June through September. Seeds in sticky pods arranged in a row of 2-5 segments appear August–October. This species is very similar to Desmodium perplexum from which it was recently split.[5]
Taxonomy
Desmodium glabellum was first described as Hedysarum glabellum by the French botanist André Michaux in 1803.[6] The Swiss botanist Augustin de Candolle placed Hedysarum glabellum Michx. in genus Desmodium in 1825,[1] and so the latter is a basionym for Desmodium glabellum (Michx.) DC.[2]
In 1950, the American botanist Bernice Schubert rejected the name Desmodium dillenii Darl. as a nomen confusum.[7][8] Schubert split the taxon into two distinct taxa, a newly described Desmodium perplexum B.G.Schub.,[9] and the previously described Desmodium glabellum. (As of February 2024), the name Desmodium dillenii Darl. is treated as a synonym for Desmodium glabellum (Michx.) DC.[2] Historically, the latter is known as Dillenius' ticktrefoil.[3]
