corollas " rubrae " roseas vel " albas " tubo calyceni paullo superante, 

 lobis amplis latissime cuneato-obovatis integris nunc erosulis ; ovuli's in 

 loculis 3, rarius binis. P. triovulata, Thurber in Bot. Mex. Bound. 

 p. 145. — Var. glabella : ramis simplicioribus erectis ; foliis angus- 

 tioribus. — New Mexico (near Santa Fe, &c.) and adjacent borders of 

 Texas and Colorado. (No. 1654, Wright, may be added to the num- 

 bers cited in Mex. Bound. Survey ; this and 504 are of the smoothish 

 and more erect variety.) Limb of the corolla commonly an inch, 

 sometimes an inch and a quarter in diameter : apparently a showy 

 species. No state of the plant seen can justly be described as "canes- 



cently pubescent."
