other in an open fewer-flowered raceme ; the corolla of C. Jamesii 

 is nearly if not quite straight, that of the other is quite saccate at 

 base dorsally, thus causing the corolla to be turned aside at quite 

 a strong angle with the axis of inflorescence and nearly erect pedi- 

 cels ; the calyx of C. Jamesii is large and " funnelform," that of 

 C. Tzveedyi is short and more lobed ; while the lower lip of C. 

 Jamesii is coated with a thick mat of hairs, the lower one of C. 

 Tzveedyi is merely strongly papillate. 



To sum up, then, the two plants resemble one another in the 

 ovary and seeds, in the stamens fertile and sterile, in the upper 

 parts of the corollas, in the leaves and their bases, and in their 

 blackening when dried. They depart from one another in the in- 

 florescence, in the corolla-base, in the hairiness of the lower co- 

 rolla-lip, and in the shape of calyx. The seeds and corolla base 

 would cut the plant off from Pentstemon more than from Cliiono- 

 phila. Neither could the plant be placed in Collinsia, though hav- 

 ing the gibbous base of this genus, as the stamens are not enclosed 

 in the keel-shaped sac of the lower lip, nor are the seeds "peltate 

 and concave centrally/' while the sterile filament is not a mere 

 gland. For these many reasons it seems best to the writer to 

 transfer the plant to Chionophila rather than to constitute a new 

 genus for it. 



No. 3883. It grows in Idaho, wherever I have found it, not 

 in swampy ground, as Mr. Tweedy finds it, but in open, loose soil 

 at the bases of mountains. 



Idaho County in flower, July 2, 1895. Flowers nearly white 

 with tinge of purple. Custer County in fruit, August 2, 1895. 

 Altitude about 6000 ft. 



Type in the National Herbarium, co-types in the Idaho and 

 Gray herbaria. 



Castilleia Covilleana 



Stems numerous from a subvertical rootstock, about 15 cm. 

 high, leafy from the base, throughout glandular as well as villous 

 with long crisped hairs, especially above : leaves narrow, entire at 

 base, 3-parted above into linear more or less circinate lobes, 2—3 

 cm. long: bracts broader, 3-parted and the central lobe 2-3-cleft, 

 some noticeably circinate, about equaling the flowers : calyx 

 equaling or slightly surpassed by the corolla, much deeper cleft 

 behind than before, the divisions shortly cleft into lanceolate acute
