* Gilia debilis Wats. Am. Nat. 8 : 302 [Rothr. Wheeler's Rep. fl. 



ig; Syn. Fl. 2': 147]. 



A small plant, growing among rocks, with numerous slender 

 stems, leafy only at the top, which reach above the loose rocks. 

 The Montana plants differ from the type, as figured in Wheeler's 

 Report, in having nearlv always entire spatulate leaves ; it may be dis- 

 tinct. I have not seen the type. The flowers are yellowish or rose- 

 tinged, trumpet-shaped and equal the leaves. If not a form of G. 

 debilis, it belongs to the same group as that and G. Larscni and, 

 perhaps, should be excluded from the genus. It grows at an alti- 

 tude of about 3000 m.
