Description
[edit]The species is identified by small oval hairy succulent leaves. the flower buds are burgundy red and the flowers are yellow, looking much like a small version of a Lotus pedunculatus flower head.[2]
Sometimes this species occurs as an annual plant if it is growing in certain conditions.[3]

Varieties
[edit]As of October 2024[update], Plants of the World Online accepted two varieties:[1]
- Acmispon tomentosus var. glabriusculus (Hook. & Arn.) Govaerts
- Acmispon tomentosus var. tomentosus
A. tomentosus var. glabriusculus has the synonym Acmispon heermannii, and has been known by the common name Heermann's bird's-foot trefoil.[5] As of October 2024[update], Plants of the World Online and the Jepson eFlora accept this variety rather than the species A. heermannii.[6]
