18. Penstemon bacchahfolius Hook. 



Penstemon baccharifolius Hook., in Bot. Mag. 78: pi. 4627. 1852. "Rear- 

 ed from Texian seeds gathered by Dr. Wright." Specimen collected by 

 C. Wright in 1851-52, but with exact data lost, seen in Herbarium of Col- 

 umbia University. This must be either his 439 or 1479, both credited 

 by A. Gray in Torr., Bot. Mex. Bound. 114. 1859, as collected on "rocky 

 bluffs at the Big Bend of the San Pedro River, Texas." Evidently the 

 type station. 



Limestone ledges, bluffs and canyons, in Edwards and Uvalde 

 Counties, Texas; and Rio Grande portion of Lower Sonoran Zone 

 (at altitudes of 1,000 to 1,500 feet). Ranges westward through 

 Trans-Pecos Texas. Flowering from April to June. 



Texas. Edwards: Barksdale, E. J. Palmer 11009 (M), 12337

 Viaduct, Pilsbry (A). 



Penstemon atropurpureus Raf., Atl. Jour. 1: 176. 1833 [not P. 

 atropurpureus (Sweet) G. Don 1830], said to be from Texas or 

 "Arkanzas, " to be represented by a specimen or specimens in 

 Rafinesque's herbarium and to have been seen living by him, is 

 described as with leaves "ang. lane, amplexic. seiTul. glabr. 

 acutissim." and flowers ''small, dark purple." Probably two 

 species are confused, but I can identify neither as Texan.
