the upper gradually shorter. Spikelets ascending, rhachis-joints 

 brittle, shortly puberulous, barren glumes glabrous, the lower 

 slightly (less than }. line) longer than the upper, 9-nerved below, 

 becoming 5-nerved near the apex, the upper 7-nerved below, 

 nil the nerves except the median becoming indistinct above. 

 Lowest flowering glume 3 lines long without the awn, rhachis- 

 joint '~l 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, etc. 



MossAMEDES. — A suffruticose, triticiform, pale green grass; culms 

 and rhachis brittle. Growing with Vogelin nfrlrjinn 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 csespitose 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- 

 o'reen ; 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 aAvned glume, the upper ? with a perfect 

 awn slightly exceeding the length of the glume ; barren glumes 

 shorter than the spikelet, subelliptical, acute, conspicuously 

 o-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 If ft. ; basal leaf-sheaths \\ 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 ; Hgule scarcely 

 \ line long. Panicle about G in. long by \\ bi-oad 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, 2f to 3} hue 

 including the short awn (1 to H line) ; gl. 11. separated by a 

 short internode, more elliptical than gl. L, about 3 lines long, 

 including the awn (^ 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 (f line long), gls. IV. and y .
