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 ) .
