Lectotype (designated here):― MEXICO, Sonora, Guaymas, 1887, Palmer 681 ( YU 068896 [image!] image available at https://plants. jstor.org/stable/10.5555/al.ap.specimen.yu068896; isolectotype: K000572639 [image!] image available at https://plants.jstor.org/ stable/10.5555/al.ap.specimen.k000572639, NDG 15716 [image!] image available at https://plants.jstor.org/stable/10.5555/al.ap. specimen.ndg15716; paratype: MEXICO, Baja California, Cape San Lucas , 1859, Xanthus 93, US00102982 [image!] image available at http://n 2t.net/ark:/65665/356aec902-ac44-42d6-b8c8-832c9660462b).

Typification of the name Boerhavia xanti : ― Watson (1889: 69) provided a description and cited two collections ( Xanthus 93 and Palmer 681; sintypes according to Art. 9.6 ICN). Xanthus’s specimen is desposited in US (barcode US 00102982), whereas we found three Palmer’s specimen (barcodes K000572639 , YU 068896, and NDG 15716). Although Xanthus’s specimen was the first to be collected and shows flowers and mature anthocarps, one among Palmer’s specimens ( YU 068896) , is in better condition and also shows mature flowers and anthocarps, which is why YU-068896 is designated here as a lectotype.

Distribution in Mexico:―Endemic to the country, it has been reported from Baja California, Baja California Sur, Sinaloa and Sonora ( Villaseñor 2016). In Sonora it is distributed in Pacific Lowlands and Sonoran biogeographic provinces ( Fig. 4B View FIGURE 4 ), and has been collected in Benjamín Hill, Empalme, Granados, Guaymas, Hermosillo, La Colorada, Puerto Peñasco, Santa Ana, Soyopa and Ures municipalities, in xerophytic scrub and subtropical scrub, especially in disturbed areas, at 50–700 m a.s.l.
