4.13. Boerhavia wrightii Gray (1853: 322) .

Lectotype (here designated):―UNITED STATED OF AMERICA, Texas, pebbly hills near El Paso September 1849, Wright 610 ( K000779302 [image!], image available at http://specimens.kew.org/herbarium/ K000779302 ; isolectotypes: MO 216324 [image!], image available at http://legacy.tropicos.org/ Image /52990; K000779301 [image!], image available at http://specimens.kew. org/herbarium/ K000779301 ; US 00102981 [image!] image available at http://n 2t.net/ark:/65665/3bcd4bc5e-b235-4257-b110- d81cb2077a53 [right-side specimen]).

Typification of the name Boerhavia wrightii : ― Gray (1853: 322) cited two sintypes (Wright 610 and Gregg 533) the Gregg’s one reported with a question mark, probably because he was not sure about the identity of this specimen [a Gregg’s specimen was traced at MO (barcode MO053222) and it is labeled as Boerhavia anisophylla Torrey (in Emory 1959: 171). Concerning the other sintype (Wright 610), three specimens were traced at MO (barcode MO216324) and K (barcodes K000779301 and K-000779302).All these three exsiccata match Gray’s protologue and corresponds to the current concept in Boerhavia (see e.g., Jepson Flora Project 2022, Spellenberg 2003). We here designate K000779302 specimen as the lectotype since there is a single and well preserved specimen on the sheet and it shows mature anthocarps and flowers.

Distribution in Mexico: ―It is reported from Baja California, Chihuahua, Coahuila, Durango and Sonora ( Villaseñor 2016). In Sonora it is distributed in Chihuahuan Desert and Sonoran biogeographic provinces ( Fig. 4B ), and has been collected in Agua Prieta, Bacoachi, Hermosillo and Puerto Peñasco municipalities, in xerophytic scrub at 200–1300 m a.s.l.
