CRASSULACEJS.

deeper valvate lobes. This genus also comprises succulent 

 suffrutescent plants, with simple or imparipinnate opposite leaves ; 

 the flowers form large racemes of cymes. Three or four species are 

 known 1 from the Cape; one of these has spread into almost all 

 warm countries. 2 



Crasssula (figs. 345-3 53) 3 presents, with the same general organ- 

 ization as in the preceding types, an androceum reduced to a single 

 alternipetalous verticil ; and 



this alone distinguishes the Crasmla {Rochea) coccinea. 



genus. The flowers are herm- 

 aphrodite and regular. In most 

 we find, inserted on a con- 

 vex receptacle, a calyx of five 

 sepals, free or united below, 

 of valvate or imbricate praeflo- 

 ration, and a corolla of five alter- 

 nating petals, free or slightly 

 united at the base, imbricated or 

 more rarely twisted in the bud. 

 Each stamen has a free filament 

 bearing an introrse 2-celled an- 

 ther of longitudinal dehiscence. 4 

 Alternating with the stamens are five glands, often crescent-shaped, 

 but varying in form, applied to the back of the carpels. These last 

 are superposed to the petals ; they are free ; each is formed of a one- 

 celled ovary, tapering above into a style which is stigmatiferous on 

 the upper inner surface. Inside the ventral angle of each ovary is

4 The pollen is analogous to that of Sedum. 

 It has three papillate bands in C. (Sepias) capensis 

 and C. (Rochea) versicolor (H. Mohl, loc, cit.).
