Lectotype (here designated):― UNITED STATES OF AMERICA, New Mexico, Stony hills near the copper mines of Santa Rita, August 1851, Wright 1725 ( GH00037320 [image!] image available at https://s3.amazonaws.com/huhwebimages/8 C 75767 E65 BB420 / type/full/37320.jpg; isolectotypes: MO 216325 [image!] image available at http://legacy.tropicos.org/Image/52962, GH00037321 [image!] image available at https://s3.amazonaws.com/huhwebimages/CBB3 E1 CF24204 F4 /type/full/37321.jpg, GH00037322 [image!] image available at https://s3.amazonaws.com/huhwebimages/43 C1 E52 AF30 A404 /type/full/37322.jpg).

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.
