Annual herb, without bulbs. Stems procumbent or ascending, less often erect, often rooting at the nodes, with spreading hairs.

Notes: The herbarium material at SRGH is separated into two varieties, namely var. corniculata and var. radicosa (A. Rich.) Roti Mich. According to Upland Kenya Wild Flowers (Agnew, 1974, page 146) the distinction between these is as follows:
  • Adnate stipules present at the base of the petiole ... var. corniculata
  • Stipules 0 ... var. radicosa
We have followed the African Plants Database in not distinguishing the two varieties.
