white, rather large, forming a short, broad subcorymbose 
cluster; fruiting raceme short, the pods 2 inches long, slen- 
der, erect on pedicels of 4 inch or more. ; 
Along streams at the eastern base of the Caseade Moun- 
tains in southeastern Oregon, Mrs. R. M. Austin, 1893. 
CARDAMINE Mopocensis. Size and habit of the last, but 
slender rather than robust, much more leafy, the herbage 
deep-green and not succulent: leaves mostly simple, oval to 
rhombic-ovate, an inch long, $ inch wide, irregularly and 
acutely 5 to 7-toothed: flowers rather few, white; fruiting 
raceme short; pods slender, 1} inches long on ascending 
pedicels less than half as long. 
Plains of Modoc County, northeastern California, on Las- 
sen Creek, Mrs. Austin, August, 1894, and on Davis Creek, 
Miss Black, in the same year; at the time referred by me 
to C. Breweri, but it is very distinct. 
3. Type of the Genus DRABA. 
The name Draga was originally, and very anciently, 
associated with a plant which, since Linnæus time, has 
been treated as a species of the genus Lepidium. The 
Lepidium Draba of that author is the type which, according 
to the law of priority should, along with its true congeners, 
constitute the genus DRABA. 
However, as the law of priority is with most botanists of 
the present a mere name, being allowed to prevail only this 
side of a comparatively recent date, the question here 
answered is, what is the type of the modern so-called genus 
Draga? In order to ascertain its type-species, one must 
consult always the original publication of a genus; and 
upon the matter of the authorship of the modern Draba 
we find contradiction between the most pretentious of recent 
taxonomic standards. In the Synoptical Flora, for example,
