specimens, in full blossom, collected on bluffs of the Arkansas, near 

 Pueblo, by my excellent correspondent, Rev. E. L. Greene. The 

 species is not only much more woody than the Californian F. grandi- 

 folia (which comes east into Nevada), but is peculiar in having the 

 ovules reduced to three, one for each placenta, and resupinate on very 

 long funiculi, which are inserted close to the base of the cell. The . 

 leaves are only 2 or 3 lines long, and much fascicled in the axils. 

 Limb of the (white) petals 2^ to 3 lines long. 



Calandrinia. A little Portulacaceous plant of the Rocky Moun- 

 tains was several years ago inadvertently, not to say carelessly, referred 

 by me to the wrong genus, namely, Talinum pygmceum. This has since 

 been more or less confused with a nearly related species of the Cali- 

 fornian sierras. Both belong to Calandrinia, having persistent calyx 

 and estrophiolate seeds, and are of the type of C. acuvlis and some 

 other South American species. Characters are appended.
