the upper graduaily shorter. Spikelets ascending, rhachis-joints 
brittle, shortly puberulous, barren glumes glabrous, the lower 
slightly (less than 3 line) longer than the upper, 9-nerved below, 
becoming 5-nerved near the apex, the upper 7-nerved below, 
all the nerves except the median becoming indistinct above. 
Lowest flowering glume 3 lines long without the awn, rhachis- 
joint 2 line, awn 7 lines, including the flattened column (1 line), 
lateral nerves conspicuously green below the tip, lobes very 
delicate, ridge of hairs white, exceeding the glume; pale scarcely 
3 lines ; lodicules rather large, cuneiform, anthers 2 lines long. 
Near the last species, but a much larger plant, distinguished 
by its long strict interrupted panicle, its larger spikelets, ete. 
MossameEpes.—A suffruticose, triticiform, pale green grass; culms 
and rhachis brittle. Growing with Vogelia african« Lam. in coarse 
sandy places near Cavalheiros on the river Onco, and by the river Bero 
in rather dry places ; July 1859. No. 2282. 
3. D. andongensis Rendle sp. nov, 
A very elegant widely cespitose glabrous perennial ; rhizome 
strong, densely fibrous; culms springing from among the closely 
massed last year’s sheaths, slender, erect ; leaves almost as long 
as the culms, erecto-ascendent, rigid, apex pungent, in the dried 
specimens convolute and subulate, when alive flat linear- 
lanceolate, or broadly linear-acuminate, shining glaucous yellowish- 
green; ligule a low ridge of white hairs ; blade sharply separated 
from the sheath; panicle linear at first, becoming irregularly 
rhomboidal, branches fastigiate at the nodes, ascending, young 
spikelets lanceolate, about 5-flowered, lowest flower ¢ with a 
shortly imperfectly awned glume, the upper 2 with a perfect 
awn slightly exceeding the length of the glume; barren glumes 
shorter than the spikelet, subelliptical, acute, conspicuously 
3-nerved, setigerous, gl. III. more ovate, with a slightly bifid 
apex, gls. IV. and V. subequal, 5-nerved, elliptical, the lateral 
nerves produced into the two acute shortly setiferous membranous 
lobes, callus short, bearing lateral tufts of short whitish hairs, 
succeeding glumes becoming shorter. 
Plants 1 to 1? ft.; basal leaf-sheaths 13 to 3 in. long, mem- 
branous, culms with 4 internodes ; cauline sheaths subequal to 
or shorter than the leaf-sheaths ; leaves reaching 10 to 12 in. in 
length, and 2 lines in breadth when flattened; ligule scarcely 
4 line long. Panicle about 6 in. long by 13 broad when mature; 
branches reaching 3 in.; spikelets shortly stalked or terminal, 
reaching } in. in length, like the rest of the plant glabrous ; 
lower barren gl. slightly oblanceolately elliptical, 22 to 31 line 
including the short awn (j to 3 line); gl. II. separated by a 
short internode, more elliptical than gl. I., about 3 lines long, 
including the awn (3 line); gl. III. subsessile, very slightly 
exceeding gl. II.; pale flattened with strong ciliolate nerves and 
retuse apex, scarcely 2) lines long; upper glumes separating 
from the glabrous rhachis-joint (3 line long), gls. IV. and V.
