WEST AMERICAN CRUCIFER2. 81 
florescence, most 10 or 12-flowered ; bracts oblong-linear, slender- 
pointed, none with woolly margin: corollas and achenes as in 
the last. 
This is n. 1690 of the Death Valley Expedition from the 
Sierra Nevada in Inyo Co., listed in the report as Bige/ovia Bo- 
landri, which type can not, I think, have been known by him who 
made this reference; and, in the U. S. Herb. the sheet was long 
since placed in the cover of C. Parryz, which it is like in habit, 
though different in character. 
MacroneMA BOLANDRI. Linosyris Bolandri, Gray, Proc. 
Am. Acad. vii, 354. Chrysothamnus Bolandri, Greene, Eryth. 
iii, 114. My remarks in Erythea, as to the seeming desirability 
of removing this type to Macronema, seem now more than ever 
forcible ; for, in looking over the numerous sheets of Macronema 
discoidea now in the U. S. Herb., I detect.something like a half- 
dozen specimens of the Bolandrian shrub, some of them from 
the original station, that have by others been taken for, and 
labelled as M. discoidea. It is even hardly more than a sub- 
Species of this genus; for it differs from that one with which 
people so easily confuse it, by no clearer characters than those 
of a rather narrower and more pointed leaf, and slightly nar- 
rower heads more numerous and apt to be crowded together. 
And there are two or three other forms under the aggregate M. 
discoidea that might almost as well be distinguished as this one. 
Certain West American Cruciferae. 
The Californian crucifere in general, and perhaps more 
especially that extensive list of species that have been variously 
referred to droit, Strepianthus, Caulanthus, Stanfordia, and 
Thelypodium have occupied a good share of my most careful and 
critical attention during the last quarter-century. 
Fifteen years ago, having in preparation the Flora Francis- 
cana, I could see no alternative between dividing the Streptanthus 
series into two or three genera, or restoring to it Cau/anthus 
and Stanfordia ; and I decided in favor of the latter course. It 
was not satisfactory; and it has for some years seemed to me
