2Q. M. nossibeensis^ Steud. Syn. PI. Glum. ii. 63. Robust. 

 Umbel simple or subcompoimd. Rays often 12, up to 4 J in. long, each 

 terminated by a cylindric spike, or sometimes by 3, the two small 

 lateral spikes being sessile or short-peduncled up to \\ by nearly 

 J in., very dense, in fruit green or whitish-green. Spikelets in fruit 

 (at least the lower) deflexed, oblong-lanceolate, maturing 2 nuts. Nut

 Fl. Afr. V. 594. Spikelets in fruit oblong, subtetragonous, J by y\in.,

The leaves are not longer than the leaVes of M. sieberianus frequently are; 1 ut 

 they are much more flaccid. The spikes are much less dense than commonly in 

 M. sieberianus ', they have about 25 spikelets. The species resembles a good deal the 

 American Cyperus ietragonus, Elliot. 



28. M. Phillipsise, C. B. Clarke. Stems 8 in. long or more, 

 slender, trigonous and smooth at the top. Umbel simple ; rays 6-8, 

 up to 1:1 in. long; bracts 5-6, flaccid, green, lowest up to 0-9 by ^ in. 

 Spikes on each ray | by \-^^ in., cylindric, very dense, green obscurely 

 variegated with dull ferruginous red. Spikelets \ in. long, hardly at 

 all compressed, perfecting o nuts. Lowest empty glume small, ovate, 

 with a linear mucro, upper empty glume rather shorter, quadrate, 

 truncate. Fertile glumes ovate, long acuminate with minute recurved 

 mucro, 7-11-ribbed. Nut J the length of the glume, obovoid', trigonous, 

 dark brown.

This is close to M. tanyphyllus • but has very dense spikes, and the fertile glume* 

 much acuminated.
