1. F. miliacea, VahJ. 



Csespitose, usually 1-2-5 ft. high. Stems angled or almost winged 

 above embraced at base by the large leaf-sheaths. Leaves usually 

 well developed and frequently as long as stem, •07--2" broad, many- 

 nerved. Branches of umbel often strongly 3-quetrous and scabrid. 

 Spikelets very many in decompound umbels 1-6" diam., sub-globose,^ 

 •08" long, usually one central sessile and 2-5 lateral with slender 

 pedicels on the final branches of the umbel. Glumes •04--05" long, 

 ovate-cymbiform, keel scarcely excurrent or submucronate. Nut 

 obovoid 3-gonous, •02--025" long, minutely transversely striate (with 

 transversely elongate cells) and often minutely verrucose, pale straw- 

 coloured. Style about equal to nut with pyramidal base, scantily 

 pubescent near the 3 stigmas.

Clarke says hardly separable from quinqiiangularis, but it appears to me very 

 distinct. The rhachilla is nearly or quite naked after the fall of the glumes or the- 

 scales are very inconspicuous; one empty narrowly lanceolate glume-like bract is, 

 however, sometimes persistent at the base. The glumes have a pale midrib and a 

 dark brown streak each side of it and lighter brown sides almost exactly as in 

 qninquangidaris. 



2. F. quinquangularis, Kunth. 



Csespitose with many angular stems usually 1-2 ft. high, sometimes 

 flattened at the base, rarely leafless. Leaves usually half to as long 

 as stem, many-nerved, •05--07" broad, rarely leafless. Spikelets very^
