254 XXVIII. GRAMINE.E. [Eragrostis 



Near E. cylindrispica, which it closely lesembles in habit, but 

 is a less robust plant with smaller less coriaceous spikelets and 

 pales with much more narrowly winged keels.

 and Luxillo ; 28 April 1857. No. 2735. In rather damp sandy

40. E. guingensis Rendle sp. nov. 



Csespitose apparently perennial with a strong slender woody 

 rhizome ; culms tall .slender, erect, terete, glabrous, springing 

 from a tuft of slender erect convokite almost acicular sparsely 

 scabridulous-hairy leaves, surrounded at the base by the withered 

 sheaths ; panicle elongated, strict, branches subdistautly alternate, 

 erect, bearing the flattened ovate to elliptic-ovate purplish-green 

 subsessile 8- to 11 -flowered .spikelets or reduced branchlets from a 

 short distance from the base upwards, rhachis articulate between 

 each flower ; glumes spreading, the barren generally slightly 

 shorter than the fertile, subequal, ovate-lanceolate, acute, keels 

 scabridulous with strong apex, imperfectly 3-nerved, lateral 

 nerves weak ; fertile glumes subcoriaceous, ovate-acute, lateral 

 nerves well-marked in the lower half ; pale slightly shorter, keels 

 prominent, shortly scabridulous, back narrowly elliptical when 

 flattened, apex truncate. 



Plants reaching about 2 ft. high ; culms with 3 internodes, the 

 lowest very short (^ in.), the median 2 in. or less, the uppermost 

 very much elongated and bearing the infloi-escence, the 2 lower 

 enveloped by the narrow cylindrical sheaths, pilose at the mouth 

 only ; ligule a very short hairy lidge, blades reaching 6 in. in 

 length rarely exceeding I line in thameter. Panicles reaching 

 15 in. long, by ^ to 1 in. broad • lower branches 2^ to 3^ in. long ; 

 spikelets |- to i'in. long by 2 to 2] lines broad; barren glumes 1] 

 line long, fertile glumes H- line; anthers purplish-brown f; line. 



Near E. Jlavicans Welw. but distinguished by its narrow 

 acicular leaves and longer strictly branched panicle. 



PuNGO Andongo. — A strictly erect grass with the habit of Pna, 

 2 ft. high, growing sparsely in rock-crannies at Pedras de Guinga ; 

 Jan. and March 1857. Nos. 7407, 7414. No. 2865 (no notes). 



Var. egregia Rendle var. nov. 



Plants 3 to 4 ft. high, with flattened linear or convolute leaves 

 over a foot in length and reaching 2 lines in breadtli ; panicle 

 immature, over l\ ft. long, resembling that of the type but on a 

 larger scale. 



Perhaps a distinct species but the spikelets are insufiiciently 

 developed for description. 



PuNGO Andongo.— A grass 3 to 4 ft. high, growing caespitosely in 

 the rocks of Pedras de Guinga and near Calundo, which consist of 

 sandy black very hot schist ; Jan. and March 1857. No. 2759. 



Specific determination is impossible in the case of the following 

 numbers, as the inflorescence is immature.
