Perityle emoryi
Perityle villosa
Perityle emoryi is a widespread polyploid of diverse habitats and is often weedy. It is variable; none of the variation appears to have population significance and does not require taxonomic recognition. The range of P. emoryi appears to be gradually expanding.

Of conservation concern.
Perityle villosa occurs in the Inyo, Panamint, and Grapevine mountains in and near the Death Valley region. Two distinct morphotypes characterized by either entire or lobed leaves appear to exist in Hanaupah Canyon in the Panamint Mountains. Some chromosomal evidence suggests that the variability of P. villosa within that population may result from the co-occurrence there of diploids, triploids, and tetraploids.
