﻿i 9 i6] NELSON 6r MAC BRIDE— WESTERN PLANTS 45 



The galea of the latter plant is nearly or quite as long as the tube. 

 Measured by this yardstick the group divides into two species 

 which are more or less distinct in habit and aspect. Both present 

 interesting and analogous variations in pubescence; one, C. rexi- 

 jolia var. pubens Nels. and Macbr., with this interpretation of C. 

 confusa must become 



Castilleja confusa Greene var. pubens (Nels. and Macbr.), 

 n. comb. — C. rexijolia Rydb. var. pubens Nels. and Macbr. Box. 

 Gaz. 55:380. 1913. 



Castilleja miniata Dougl. var. crispula (Piper), n. comb. — 

 C. crispula Piper, Contrib. Nat. Herb. 11:516. 1906— The bracts, 

 at least the uppermost, are few-toothed near the apex. The 

 species varies somewhat in the dissection of the bracts. 



Castilleja angtjstifolia (Nutt.) G. Don var. subcinerea 

 (Rydb.), n. comb.— C. subcinerea Rydb. Bull. Torr. Bot. Club 

 40:484. 1 913. — Since Fernald published his discriminating analy- 

 sis of this group (Eryth. 6:41-51), several additional species have 

 been described, among them C. subcinerea Rydberg. This form 

 is of particular interest as it in some degree connects C. angusti- 

 folia and its varieties with C. Bennittii Nels. and Macbr. of south- 

 western Idaho. The latter is very distinct, however, by reason of 

 its subequal corolla and calyx and the color of its bracts (old rose). 

 The eastern Idaho plant (C. subcinerea), although simulating 

 C. Bennittii in pubescence, has the well-exserted corolla and 

 relatively long calyx (2-3 cm.) of the old species. It would seem 

 conducive to clearness and more natural, therefore, to treat it as 

 another variety of C. angustifolia, regarding its pubescence as its 

 most marked characteristic. 



Cordylanthus bicolor A. Nels. Bot. Gaz. 54:4 i6 - 19 12 " 

 Rydberg (loc. cit) states that this species " is evidently the same 

 as Adenostegia ciliosa Rydb." The latter, however, is the same 

 as C. ramosus Nutt., which has 4 stamens and 2-celled anthers. 

 C bicolor is distinguished from C. capitata, its nearest relative, 

 which has 2 stamens and 1 -celled anthers, by its viscid-glandulosity 

 and the presence of a rudimentary anther cell. 



Ricinophyllum horridum (Sm.), n. comb. — Panax horridum 

 Sm. Rees Cycl. 26: no. 10. 1812; R. americanum Pall, ex Ledeb.
