The leaves are not longer than the leaves of M. sieberianus frequently are ; but 
they are much more flaccid. The spikes are much less dense than commonly in 
M, sieberianus ; they have about 25 spikelets. Thespecies resembles a good deal the 
American Cyperus tetragonus, Elliot. 
28. M. Phillipsiz, (. B. Clarke. Stems 8 in. long or more, 
slender, trigonous and smooth at the top. Umbel simple 5 rays 6-8, 
up to 1} in. long; bracts 5-6, flaccid, green, lowest up to 6-9 by 4 in. 
Spikes on each ray 2 by 4-4 in., cylindric, very dense, green obscurely 
variegated with dull ferruginous red. Spikelets } in. long, hardly at 
all compressed, perfecting 3 nuts. Lowest empty glume smal], ovate, 
with a linear mucro, upper empty glume rather shorter, quadrate,

This is close to M. tanyphyllus ; but has very dense spikes, and the fertile glumes 
much acuminated,
