without obvious distinction of tube and limb, a corolla much 
resembling that of the ordinary Nemophila, to which genus 
Capnorea is now confessed to be allied, though not very inti- 
mately.

1. ©. Catrrornica. Ourisia Californica, Benth. Pl. Hartw, | 
327; C. nana, Greene, Eryth. ii. 193 in part, not of Rafinesque. — 
The only plant known to me that answers Bentham’s descrip: 
tion as to small ovate ciliate leaves, ovate ciliate calyx-segments, 
etc., etc., is something of a rarity in the herbaria, and is know! 
only from the western slope of the Sierra Nevada, California, 
Since Hartweg’s day among the mountains of the Sacramento, — 
I do not know of this plant’s having been collected except at | 
Emigrant Gap, by Marcus Jones, in 1882, and at some station 
further north in Placer County, by Mrs. M. M. Hardy, in 1893, 
I know of no California botanist’s ever having seen the plant 
growing. Dr. Kellogg even, who explored these regions in early 
years perhaps as carefully as I have done in less remote days, 
seems never to have recognized it. Itis an excellent species, 
and .Bentham’s account of it is sufficiently clear, as to the _ 
characters. 
2. C. CILIATA, Greene, Eryth. ii. 193. Hesperochiron ciliatis, 
Greene, Pitt. i. 282. This species, perhaps somewhat loa E 
that remote desert tract of southern Nevada, is still unknown — 
to me except in the type specimen. Its corolla, though small 
and short, does not seem to be rotate. The species has a new 
ally in my C. Zeporina of the Mojave Desert. 
3. C. WATSONIANA. Hesperochiron Californicus, Wats. Bot. 
King, 281, t. 30, but not Ourisia Californica, Benth. Excellent 
species of eastern Nevada and adjacent California, well enoug? 
described by Mr. Watson, though poorly figured, Its leaves
