58 ERYTHEA. 



hicorne there can be no room for two opinions. The original 

 description, covering almost half a page, is answered to in 

 every particular, by the plant whose salient features are so 

 well shown in Mr. Small's plate 18. 



GiLiA CAPiLLARis, Kell. Proc. Calif. Acad. v. 46 (1873). 

 Very glandular and somewhat viscid throughout; branches 

 rather short and ascending, the panicle not effuse; corolla 

 white or pale purplish, barely 2 lines long and only about 

 twice the length of the calyx, the proper tube not surpassing 

 the calyx- teeth: style short, the stigmas not exserted. 



/ Gilia leptalea. Collomia leptalea, Gray, Proc. Am. 



Acad, viii, 261 (1870), chiefly. Less glandular, often quite 

 glabrous: less leafy and the leaves narrower: branches more 

 slender and divergent, the panicle therefore truly effuse: 

 corolla fully i inch long, of a deep rich red-purple; the 

 slender tube twice the length of the calyx, this widening into 

 an ample/'fannelform throat which is nearly as long as the 

 proper tube: style elongated, the stigmas borne beyond the 

 corolla-lobes. 



Thus are given the essential characters of two perfectly 

 distinct species belonging to the middle and higher Sierra 

 Nevada of California; one an insignificant weed, the other a 

 very beautiful plant.
