﻿268 Heller : New Plants from 



Castilleja lutea. 



Perennial, clothed throughout with lanate pubescence ; stems 

 clustered, 20-30 cm. high : basal and lower stem leaves lanceolate, 

 narrow, those of the upper part of the stem oblong, or somewhat 

 obovate, the upper half, or third, usually three-lobed, all of the 

 lobes lanceolate, but the lateral ones narrower and acuminate, the 

 middle one usually again three-lobed, with its lateral segments 

 narrower ; floral bracts pale yellow, or the tips somewhat purple 

 tinged, more unequally toothed or lobed than the foliage leaves, the 

 terminal segment broad and rounded, the others narrowly lanceo- 

 late ; calyx oblong, about 3 cm. long, equally cleft before and be- 



hind, the lobes about equalling the tube, slightly dilated and 



notched at the blunt apices ; corolla barely exserted, the galega 

 equalling or a trifle shorter than the tube, faintly tinged with purple, 

 or yellow. 



The type is no. 3267, collected May 20, 1896, on grassy hill- 

 sides near the mouth of the Potlatch river, Nez Perces county, 

 altitude 1200 feet. It is also abundant on the plateau below Lake 

 Waha. It may be looked for in herbaria under the mixture called 

 11 Castilleja parviflora Bong.," although I have never seen any 

 other specimens. It is found growing with this other species, but 

 can be distinguished from it at a glance. It is a smaller plant than 



parvifli 



cence. 



Our specimens somewhat resemble the type of EucJiroma 



Bradburii Nutt., preserved in the herbarium of the Academy ot 

 Natural Sciences, Philadelphia, but is apparently not the same, so 

 far as can be ascertained from that poorly prepared and fragment- 

 ary specimen. 



C. lutea may possibly be the same as C. dese riorum Gey en 

 published by Hooker as a synonym of C. hispid a, in Journ. ot 

 Bot. and Kew Garden Misc. 5 : 258. 1853, where the following » 

 given : " Prairie plateaus of the Nez Perces Mountains. 

 Except in color, I do not see how these specimens of Mr. Geyers 

 £ desertarum (no. 511) differ from what I consider to be a mere 



hispida
