 colour. Flowers axillary. Peduncles often accompanied by a pair of 

 smaller leaves. Calyx, leaves three, pointed. Petals narrow, pointed, 

 white or tinged with red. 



This minute and depressed plant becomes conspicuous only in ample 

 reddish patches, which it presents to the eye, throughout the sandy 

 wastes where it dehghls to grow. The whole plant is smooth. " The 

 flowers are naturally three-cleft, and of course triandrous, hut they are 

 sometimes four-cleft in strong plants, and Gsertener says five-cleft. 

 Still the want oi nectaries keeps them generally distinct from the chiefly 

 African genus Crassulay
