9. A. brasiiiensis, C.B. Clarke in Durand d: Schinz, Cotispect. Fl. 

 Afr. V. 651. Stems attaining 2-2 J ft. in length. Spikelets often 3-6 

 in the head, less fused together than in A. capensis^ somewhat cinnamon- 

 coloured. Ovary and nut stalked ; otherwise as^. capensis. — Platylepis 

 hrasiiiensis, Kunth, Enum. ii. 269 ; Boeck. in Linnsea, xxxvii. 119.

Also in Madagascar, and tliroughout South America. 



This species is very close to A. capensis. It is separated solely by the minute 

 stalk to the nut. 



16. RYNCHOSPORA, Vahl; Benth. et Hook, f . Gen. PL iii. 

 1058 {Rhynchospora). 



Spikelets of 1 or more perfect flowers. Uppermost glumes male or 

 sterile, the 3 lowest usually empty and smaller. Hypogynous bristles as 

 long as the nut, or shorter, or often 0. Style long, linear, either 

 minutely bifid at the tip (Series, Haplostylem), or with two linear 

 branches longer than the style (Series, Diplosiylece) ; style base dilated, 

 large or small, persistent. Nut obovoid to narrowly oblong, flattened. 



Species 184, i.e. including P*t7oearj/a, but excluamg Pleurostachys (Sect., Bentli, 

 ct Hook, f.), throughout the World, especially abundant in America. 



This genus, from its 2-fid style, and persistent enlarged style-base, should not be 

 mistaken for anything but Fimhrisiylis. From this, either the inflorescence or in 

 the 1-headed species the hypogynous bristles separate it, except in the case ot 

 R. erinacea (which has nodes on the stem). 

 *Haplostyle^, — Style very long, minutely 2-fid at the top or subeutire. 

 Spikelets in one dense head ; stem with no nodes 

 between the head and the basal leaves.
