 Umbel simple or rarely reduced to 1 head ; rays 3-8 ; bracts 4-.'), 

 lowest up to 6-10 in. long, similar to the leaves. Spikes of 3-20 

 spikelets, loose. Spikelets up to § by i in., 22-flowered, compressed, 

 yellow-brown. Glumes ovate, keeled, a little inflated; tip triangular ;

 of the Zambesi, Holub 1 Nyasaland ; Namasi, Cameron, 22 ! 



Also in South Africa, India, Australia, and Tropical America. 



This species occurs iu Natal and the Transvaal, and is very likely to occur in 

 Tropical Africa, whether Holub's example is rightly named or no ; and his thcrefure 

 been included in this Flora. Holub's specimens are 5-7 in. high only, with a single 

 loose head of 4 large spikelets on each. The woody stem and spikelets do very well 

 for an extremely depauperated P. angulatus ; but the Hovvers are quite young and 

 the identification altogether uncertain. 



33. P. albomarginatus, Nees in Mart. Fl. Bras. ii. i. 9. A large 

 annual. Stem solitary, 1-3 ft. high, triquetrous at the top, smooth. 

 Leaves f the length of the stem, ^\ in. broad.. Umbel usually com- 

 pound; primary rays 3-11 up to 1-7 in. long; bracts 3-6, lowest up to 

 8-18 in. long, similar to the leaves. Spik6s subglobose, 1:^ in. long, of 

 12 spikelets, or very loose, elongate, 2 in. long, of 8-10 spikelets. 

 Spikelets up to 1\ by J in., flattened, straw-coloured or yellow, 1^-30- 

 flowered. Glumes ovate, obtuse, distant, with white margins. Nut n 

 the length of the glume, up to -^^ in. long, compressed, ellipsoid, black.
