E. capensis, Nees, is a M isca nthidium (M. capense, Stapf) which so far has 
not been observed outside of South Africa. TJie determination is very doubtful. 
4. E. flavescens, K. Schum. in Engl. Pfl. Ost-Afr. C. 96. Culms 
including the panicle over 5 ft. high. Leaf-sheaths quite glabrous ; 
ligules membranous, 1 lin. long, with dense hairs up to 4 lin. long ; 
blades over 1 ft. by up to 7 lin., smooth, midrib very stout. Panicle 
about 1J ft. long, narrow. Spikelets 2 lin. long, yellowish, with a 
basal ring of hairs of the same length. Lower glume sparingly hairy. 
Fertile valve densely hairy, with an awn as long as the spikelet.

5. E. violaceus, K. Schum. in Engl. Pfl. Ost-Afr. C. 96. Only 
known from a portion of an inflorescence. Spikelets 2 lin. long, 
reddish, basal ring of hairs of the same colour. Lower glume almost 
glabrous. Fertile valve much less hairy than in the preceding species.

Schumann says that E. flavescens and E. violaceus can only be compared with 
E. Sorghum which is a Miscanthidium ( M. Sorghum, S tapf). There is nothing 
in the descriptions to throw any light on the affinity "of these two species. 
24. ERI0CHRYSIS, Beauv. Agrost. 8. 
Spikelets 2-nate, of each pair similar, differing in sex and slightly 
in size, one sessile, the other pedicelled, on the articulate fragile 
rhachis of racemosely arranged spike-like racemes, the pedicelled 
falling from their pedicels, the sessile deciduous together with the 
contiguous joint of the rhachis and pedicel. Florets 2, lower reduced 
to an empty valve, upper $ in the sessile, $ in the pedicelled spike- 
lets. Glumes more or less equal, lower chartaceous or coriaceous, 
with narrow inflexed margins, with several intracarinal nerves, 
upper thinner, 1-3-nerved. Valves hyaline, muticous, nerveless, 
of the upper floret smaller. Valvule 0. Lodicules 2, cuneate. 
Stamens 3, in the pedicelled spikelet rudimentary. Stigmas laterally
