CLASSIFICATION 171 
Pollination.—Flowers slightly protandrous, visited by insects 
for honey. Both cross- and self-pollination may take place. 
Uther Genera,—This order is well represented in South Africa, 
and the plants belonging to it are eas€y recognised by their 
regular flowers, apocarpous pistils, and well-marked xerophytic 
character. Cotyledon and Bryophyllum are gamopetalous. The 
former has 10 stamens, the latter’s leaves have the peculiar 
property of developing adventitious buds on their margins, which 
give rise to new plants, hence it is called “Leaf of Life” or 
“Kannidood”. Kalanchoe has a gamopetalous corolla, and parts 
in fours. Sedum, with large pink inflorescences, is cultivated in 
rockeries, and so are Sempervivum and Echeveria. Rochea is a 
well-known South African genus,
