on generally yellow, sometimes pale primrose tint. The leaves are 2-8 lines long, 
1-4 wide, a pair at each fork of the stem, the upper ones depauperated. The 
characters given to the above varieties are by no means constant, and probably in- 
termediate stages between all may easily be found.

Shrubby, suffruticose or herbaceous succulents, sometimes annual, very variable 
in habit and size. Leaves opposite, very generally connate, broad or narrow, flat 
or semiterete, more or less fleshy, entire, rarely petiolate, frequently cartilagineo- 
ciliate, either glabrous or pubescent or scaly. Flowers mostly small, white, red or 
rarely yellow, in cymes or cymules, sometimes solitary, sometimes subumbellate or 
capitate. The petals vary much in shape and in degree of cohesion, and the genus 
has (as appears from the copious list of synonyms given above) been subdivided 
into sev “ genera ” distinguished one from another by differences in the petals. 
The most obvious of the groups of species so segregated are retained in the 6 sec- 
tions into which I have divided the genus. I regret being obliged to leave so many 
species of older authors undetermined ; but as most of them have been named in 
gardens, have never been figured, are not contained in any Herbarium, and have 
been scarcely more than indicated by the curt descriptive phrases of Haworth, it is 
quite impossible to make them out satisfactorily. Even Thunberg, who describes 
57 species in his Flora, has. preserved specimens of but 12 in his Herbarium! The 
= name is a diminutive of crassus, thick ; referring to the succulent or fleshy 
oliage.
