1. Fouquieria purpusii T. S. Brandeg. Univ. Calif. Publ. Bot. 3: 386. 1909. 

 Known only from Cerro de Coscomate, Oaxaca, on rocky slopes at an altitude 



of 2,000 to 2,200 meters. 



Tree, 4 to 8 meters high, the trunk 50 cm. tliick or more at base, tapering 

 upward, gray, with spreading branches ; leaves 3 to 5 cm. long ; spines 3 to 4 

 cm. long; inflorescence corymbose-paniculate, the flowers short-pedicellate; 

 corolla 1 cm, long, white, the lobes acuminate ; stamens 10 ; capsule 1 cm. 

 long. 



For an account of the species, accompanied by two illustrations, see A. 

 Purpus in Moller's Deutsche Gartner-Zeitung 25 : 8-9. 1910. In habit the plant 

 resembles Idria columnaris, the trunk suggesting an inverted carrot. 



2. Fouquieria burragei Rose, Journ. N. Y. Bot. Gard. 12: 267. 1911. 

 Known only from the type locality, Pichilinque Island, Baja California. 

 Shrub or tree, 3 to 7 meters high, with very short trunk and long simple 



spiny branches; spines about 1 cm. long; inflorescence simple or with few 

 branches, the flowers subsessile ; corolla 10 to 12 mm. long, pale purple or 

 nearly white. 



3. Fouquieria fasciculata (Roem. & Schult.) Nash, Bull. Torrey Club 30:452.

Fouquieria splendens micrantha Loesener, Repert. Sp. Nov. Fedde 9: 357. 1911. 



Durango to Queretaro and Hildago ; type from Puente de la Madre de Dios 

 (Hidalgo ?) ; perhaps also in Coahuila. 



Shrub or tree, 4 meters high or larger; leaves oblong-obovate or spatulate, 

 2 to 3 cm. long, obtuse or rounded at apex ; panicle usually narrow, the flowers 

 short-pedicellate; corolla red, 10 to 14 mm. long. " Ocotillo," " teocotillo," 

 " albarda," " alabarda,'' " barda " (Durango). 



It is probably this species which, according to Altamirano, is known in 

 Queretaro as " chiquina." The pulverized seeds are used in Durango as a 

 remedy for toothache, and the stems for fences and sides of huts. 



The species was described from fruiting material, and the inflorescence is 

 described and illustrated as being corymbose-paniculate. It may be, therefore, 

 that the name fasciculata does not apply to the plants placed here by the 

 w^riter. Material from Hidalgo agrees with Durango specimens upon which 

 Fouquieria campanulata is based, and since no other species is represented in 

 recent collections from Hidalgo, it seems probable that the names F. fasciculata 

 and F. campanulata refer to the same species.
