and Peebles, with the tube and throat of the corolla 35 to 40 mm. 

 long and less than 3 mm. wide at the orifice, in pressed specimens. 

 In typical G. aggregata, the tube and throat are usually less than 35 

 mm. long and 3 to 4 mm. wide at the orifice. The variety differs also 

 in the color of the corolla, this being purplish pink, the lobes lineate- 

 spotted with darker purple and with long attenuate tips. The var. 

 macrosiphon is known only from the type locality, Santa Catalina 

 Mountains, Pima County, about 7,500 feet. A form that is similar 

 to this variety in corolla color but has the normal stout corolla tube 

 occurs on the Kaibab Plateau.

Proc. 20: 301. 1885. 

 Cochise and Santa Cruz Counties, 4,000 to 8,200 feet, stony slopes 

 and openings in pine forests, August to October. Southern Arizona

Proc. 8: 261. 1870.

 ward as the Baboquivari Mountains, about 5,000 feet, open slopes and 

 canyons, August to October. Southern New Mexico, southern 

 Arizona, and northern Mexico. 



Arizona's showiest species, excepting G. aggregata, and worthy of 

 cultivation. The corolla varies from dark bluish purple to wine color, 

 and shows considerable variation in the diameter of the tube and the 

 width and apiculation of the lobes. There is also much variation in 

 the length of the anthers.

 where), 3,000 to 5,000 feet, plains and mesas, April to June. Western

 represented by Arizona specimens identified on technical characters 

 as G. polycladon.
