Dudleya hendrixii S. McCabe & Dodero is a succulent endemic, restricted to a small area of Colonet Mesa (Baja California, Mexico). It is similar to the more widespread D. blochmaniae (Eastw.) Moran subsp. blochmaniae, which has been placed in subg. Hasseanthus (Rose) Moran, and to D. attenuata (S. Watson) Moran subsp. orcuttii (Rose) Moran, which has been placed in subg. Stylophyllum (Britton & Rose) Moran. Both of these other species have much wider ranges. Dudleya hendrixii differs from D. blochmaniae subsp. blochmaniae in having fewer, terete, more upright, and waxier leaves. Unlike D. attenuata subsp. orcuttii, D. hendrixii is summer deciduous, acaulescent, and has much shorter inflorescences.
