SOME CASTILLEIAS OF THE. PARVIFLORA GROUP. 51 



C. foliolosa. The pubescence, however, is not tomentose, nor are 

 the calyx-segments rounded as in that species. 



C. Elmeri. Perennial, stems simple, single or in small clusters, 

 2 or 3 dm. high, with the leaves and bracts viscid-pilose through- 

 out, with some long hairs above: leaves 2 to 4 cm. long, rather 

 crowded, ascending, the lowest linear-acuminate, the upper lanceo- 

 late or oblong-lanceolate, becoming bluntish ; the broader indistinctly 

 3-nerved : bracts oblong or obovate-oblong, entire or rarely slightly 

 lobed at the tip, 2 to 2.5 cm. long, the lowest green, the uppermost 

 crimson or rose-purple : calyx 18 or 20 mm. long, subequally cleft 

 half way to the base (a little deeper cleft before than behind); the 

 lobes entire or cleft into lanceolate segments: corolla 2 to 2.5 cm. 

 long, the green-backed galea half as long as the tube; the lip included 

 or slightly exserted, 1.5 to 2 mm. long, with 3 oblong blunt incurved 

 lobes, about one-fourth as long as the galea. — On Wenatchee Mts., 

 19.3 km. south of Ellensburg, Washington, July 5, 1897 (A. D. E. 

 Elmer, No. 457). A puzzling plant, seemingly distinct from any 

 described species, but of doubtful affinities. Habitally it resem- 

 bles forms of C. Integra, from which it is separated by its very 

 different pubescence. From the parviflora group it is distinguished 

 by its usually entire bracts; and from most of that group it differs 

 in its comparatively short galea. In this character as well as in its 

 entire leaves and bracts the plant approaches the pallida group, 

 though the galea is rather longer than is generally found in that 

 group.
