Etymology: —The name of this species honors C.G. Pringle, collector of the type specimen. Distribution and Ecology: —This species is endemic from the states of Oaxaca , Puebla , and Veracruz ( Fig. 13C ). Collections are from xerophytic scrubs ( Acacia , Brahea dulcis (Kunth in Humboldt, Bonpland, and Kunth 1815 [1816]: 300) Martius (1838: 244) , oak forests ( Quercus acutifolia Née (1801: 267) , Q. rugosa with Arbutus , Juniperus flaccida , and Rhus ), pine forests, Pseudotsuga menziesii forests, and pine-oak forests, at elevations of 2000–3048 m . Phenology: —Flowering and fruiting occur from August to March. Discussion: —Please see L. paneroi to know more about the similarity with L. pringlei . Nomenclatural notes: —The type collection of Lamourouxia pringlei has numerous duplicates in several herbariums widely distributed. It was selected as lectotype the specimen MO-155211! because it exhibits the branching pattern with open inflorescences and mature flowers. Other specimens consist mostly of two stems not branched.
