CALIFORNIA ACADEMY OF SCIENCES. 205 



First collected by Dr. Palmer, in 1875, and again by the 

 present writer, April 26, 1885. This and the preceding all 

 fall into line with K. oxycarya and K. microstachys, with 

 which they agree in the character of a solitary, smooth and 

 shining nntlet. 



K. foliosa. 



A span or more high, erect, simple, and very leafy below, 

 parting above into numerous ascending branches : spikes in 

 threes, an inch or more long, bractless, crowded: calyx 

 rigid, and armed with short but very stiff subulate bristles: 

 nutlets four, dull brown, muriculate, ventral groove open at 

 base, the short bifurcation not divaricate. 



Guadalupe Island; apparently collected by Dr. Palmer, 

 as well as by the writer, and referred to K. muriculata, to 

 which it bears little resemblance, except as to the nutlets; 

 and even these differ from those of that species in the char- 

 acter of the basal part of the groove. 



K. denticulata. 



A foot or two high, stout and erect, often with some de- 

 cumbent branches, very strongly hispid-hirsute throughout : 

 foliage sparse : spikes loose and elongated, mostly in threes : 

 calyx small, its lobes short-lanceolate, hispid, with rufous 

 bristles : nutlets four, dark brown, sharply muriculate, tri- 

 angular-ovate, with rather obvious, minutely denticulate 

 lateral angles, and an indistinct dorsal ridge, the ventral 

 groove closed, and forked at base. 



Western Nevada, 1884, Mrs. Curran. The species may 

 not be rare, and could have been referred, possibly, to K. 

 muriculata, but it is very distinct, and the nutlets are, for a 

 Krynitzkia, quite peculiar, the back of them suggestive of 

 affinity with Plagiobothrys Kingii, which inhabits the same 

 region.
