MATJESGOED AND NUT-GRASS FAMILY. 281 



There are many Cape species ; the leaves are grass- 

 like and mostly flat. The spikelets are usually tufted 

 in dense clusters. C. tcx'tilis is used for thatching. 



Ca'rex, — This is a dioecious, or more usually 

 mono3cious, genus. The glumes are imbricated all 

 round the axis, and not in two ranks like Cype'rus, 



Fig. 110. — Ca'rex. (For deecription, see text.) 



The flowers are very simple ; the male consists of 

 three stamens in the axil of a glume (Fig. 110, 3). 



This genus has several species in the Colony. They 

 are herbs with grass-like leaves. When monoecious, 

 the female spikelets are lelow the male. The same 

 arrangement occurs when both male and female flowers 

 are in the same spikelet.
