 ovato-lanceolatis, brevioribus quandoque abortivis. — This species is 

 characteristic of the Mohave Desert, but it extends into Arizona as 

 far as to Tucson. And from insudicient specimens sent in 1884 by 

 Suksdorf, from Morgan's Ferry, Yakima lliver, it would appear to 

 have made its way northward even to Washington Territory.

 nobasi subulata persistente calycis segmentis 2 ultra medium in unicum 

 coalitis arete fulcrata ! — Southern California, at the Tehachapi Pass, 

 Mrs. Layne-Curran, coll. 1884. The examination of the single 

 fruiting branch received shows this to be a peculiar species, of evident 

 relationship to the foregoing. The fruiting calyx is distorted or made 

 gibbous at .base by the enlargement of the persistent akene (of fully 

 a line in length), round which the two united subtending sepals are 

 half wrapped. jNIore specimens are desirable for ascertaining if these 

 peculiarities are constant.
