1.1. Abronia maritima Nuttall ex Watson (in Watson 1880: 4).

Lectotype (here designated):― UNITED STATES OF AMERICA, California, on the sea-coast from Santa Barbara to San Diego, s.f., Nutall s.n. ( GH00376136 [image!], image available at https://s3.amazonaws.com/huhspecimenimages/JPG-Preview/00376136. jpg).

Typification of the name Abronia maritima : —The protologue consists of a desctiption and the citation of habitat and provenance (“On the sea-coast of Santa Barbara to San Diego”). The only specimen of Abronia maritima traced, which was collected by Nuttall in San Diego California, is deposited at GH (barcode GH00376136). Although the date of collection is lacking on the sheet, there is a label that reads “presented by Elias Durand, 1866”; so, the specimen must have been collected in that year or before, and it can be considered as part of the original material used by Watson (1880: 4) to describe the species. GH specimen is here designated here as lectotype; it matches Watson’s protologue and corresponds to the currect concept in Abronia (see e.g., Jepson Flora Project 2022, Spellenberg 2003).

Distribution in Mexico: ― Abronia maritima has been reported from Baja California, Baja California Sur, Colima, Jalisco, Nayarit, Sinaloa and Sonora ( Spellenberg 2003, Villaseñor 2016). In Sonora it is restricted to the Sonoran biogeographic province ( Fig. 4A ), and it has been collected in Guaymas, Hermosillo, Huatabampo, Pitiquito, Puerto Peñasco and San Luis Río Colorado municipalities in beach dunes of continental shores and islands (Isla Tiburón and Isla Alcatraz), at 0–20 m a.s.l.
