PHYSARIA NEWBERRYI, (sp. nov.;) pube stellat issima argentea; foliis radicalibus obovato- 
spathulatis acutis angulato-dentatis, in petiolum attenuatis caulibus floridis brevioribus, caulinis 
lineari-spathulatis; racemo sparsifloro; petalis linearibus patentibus calyce laxo duplo longioribus; 
silicula globoso-didyma basi haud emarginata; stylo e sinu angusto leviter exserto. ‘‘ Near 
Tegua, (Moqui village,) May 14; in tufts, on rocks. A singular plant; flowers irregular 
in form, and appearing ragged and past prime when in full anthesis.’’ Stems numerous in a 
tuft, from a perennial root, three inches high, erect or ascending. Radical leaves, an inch or 
_ aninch and a half long, including the petiole, three to five lines broad, generally with one or 
_ two angulate teeth on each margin; the cauline ones two to four, much smaller and narrower, 
entire or nearly so, often linear. Pedicels four to six lines long in fruit, ascending, sepals linear.

teresting addition to this small genus, and a very distinct species; in the silicle inter- 
P. didymo carpa (but less inflated and didymous) and P. Geyeri—nearest the 
silicle more inflated, and of quite a different outline. As flattened in the dried
