--><p><i>Perityle villosa</i> 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 <i>P. villosa</i> within that population may result from the co-occurrence there of diploids, triploids, and tetraploids.</p>
