2.1. Acleisanthes longiflora Gray (1853: 260) .

Lectotype (designated by Smith (1976: 272) as holotype, here corrected according to the Art. 9.10 of ICN):― UNITED STATES OF AMERICA, Texas, Valley of the Limpio; and near San Antonio , 25 August 1849, Wright 310 (Exsiccata 599) ( GH00037284 [image!], right-side specimen only, image available at https://s3.amazonaws.com/huhwebimages/70 CA156 C592 F4 F1 /type/full/37284.jpg; isolectotype: US00102870 [image!] left-side specimen only, image available at http://n 2t.net/ark:/65665/38401b176-acb1-4531- 8ff3-ecf5f7e7394f).

Typification of the name Acleisanthes longiflora : ―In the protologue, Gray (1853) cited the following collections: Wright 599 and Wright 1704, Riddell and Lindheimer (from Texas), and Gregg (Northern Mexico). However, exsiccatum no. 599 (barcode GH00037284) is actually a combination of two Wright’s original material, i.e. nos. 928 and 310. Smith (1976: 272) selected the right-side specimen of GH00037284 (it corresponds to Wright 310) as the holotype; this exsiccatum matches Gray’s protologue and corresponds to the currect concept in Acleisanthes (see e.g., Jepson Flora Project 2022, Spellenberg 2003). According to the Art. 9.6 of ICN, both collections occurring on the exsiccata no. 599 (Wright 928 and Wright 310) are sintypes, and, according to the Art. 9.10 of ICN, the typification by Smith (1976: 272) must be corrected since it actually corresponds to a lectotype.

Distribution in Mexico: ―It has been reported from Chihuahua, Coahuila, Durango, Nuevo León, San Luis Potosí and Sonora ( Spellenberg 2003, Villaseñor 2016). In Sonora it is distributed in Sonora biogeographic province ( Fig. 4A ) and has been collected in Caborca and General Plutarco Elías Calles municipalities, in xerophytic scrub, at 400–700 m a.s.l.

Other specimens: ― Texas, stony hills of the Pecos , 1 June 1951, Wright 1704 ( GH00112442 !, paratype) .
