Typification of the name Boerhavia purpurascens :― The protologue of Boerhavia purpurascens consists of a desctiption and the citation of provenance, a collector and month of collection (“Stony hills near the copper mines of Santa Rita, New Mexico , Aug. [august], Wright, No. 1725”). We traced four specimens of B. purpurascens collected by Wright in the locality cited in the protologue (barcodes: GH00037320, GH00037321, GH00037322, and MO216325; sintypes according to Art. 9.6 of ICN). The specimen GH00037320 is here designated as lectotype , since is deposited in Gray Herbarium, is in good condition and has flower and mature anthocarps. Distribution in Mexico : ―It is reported from Chihuahua and Sonora ( Spellenberg 2003 , Villaseñor 2016 ). In Sonora it is distributed in the Pacific Lowlands biogeographic province ( Fig. 4B ), and has been collected in Huásabas, La Colorada, Moctezuma, Onavas, Sahuaripa, Soyopa and Yécora municipalities, in subtropical scrub, at 200–800 m a.s.l.
