Discussion

Of conservation concern.

Phemeranthus sediformis is poorly known and merits further study in the field and better representation in herbaria. When its characters and their ranges of variation are better known, it may prove to be indistinct from P. spinescens.

Phemeranthus longipes is easily confused with smaller specimens of P. parviflorus, which it resembles in general aspect; the two are most readily distinguished by seed surface, sepal shape, root character, and stamen number. The presence of spinelike persistent leaf midribs at the stem bases has been regarded as a diagnostic feature of P. longipes; not all plants exhibit this condition, however, and some of P. parviflorus approach it closely.
