glumes and a fertile glume markedly longer than, not subequal to- 

 its pale. 



Puxcio Andongo. — A fine grass, Ciuspitose, conspicuous with its 

 rose-coloured shining spikelets. Somewhat plentiful in mountain 

 meadows between Pedras de Guinga and Condo ; March 1857. No. 7425. 



4. T. rupicola Rendle sp. nov. 



Perennial, widely csespitose, shoots decumbent-ascending, simple 

 or sparsely branched below, more or less densely branched to- 

 wards the apex ; leaves short, rigid, linear-tapering, acute, margins 

 and sheaths scabridly hairy, ligule represented by a row of short 

 hairs ; flowering-shoots terminal, elongated far above the leafy 

 tufts ; panicle small, lax, slender, spikelets long-stalked or 

 terminal on the filiform, often purplish, primary branches, erect- 

 campanulate, pilose, haii's appressed, silky, shining-white tipped 

 with purple; glume I. at the base of gl. III. minute, hairy; 

 gl. II. stout, subcoriaceous, convex, elliptical when flattened with 

 a subretuse apex, 5-nerved, the inner pair of nerves converging to 

 the apex of the midrib which passes into a fine upwardly barbed 

 awn generally exceeding the glume in length ; gl. III. subequal, 

 oblong, 5-nerved, apex flattened, cuspidate, subtending an equal 

 narrow much compressed pale with a c^ flower; fertile gl. 

 glabrous, about ^ length of the barren, thinly coriaceous, trans- 

 parent, ovate, subacute, 5-nerved, with a similar but narrower 

 subequal pale and $ flower. 



Plants a foot or moi-e high, shoots densely tufted, internodes 

 short, enveloped in the leaf -sheaths, leaf-blades -^ to 1 j' in. long 

 by 1 line or less in width, the younger ascending, the older 

 spreading and becoming purple. Inflorescence carried above the 

 leaves on a long slendei- wiry internode, which may reach 9 in. 

 long, and is sheathed at the base by a long slender cylindrical 

 glabrous reddish sheath ; fully developed panicle about 2 in. long, 

 with 12 to 24 spikelets. Spikelets about 2 lines long ; glume I. 

 including its spreading hairy coma only ^ line long; gl. II. 

 1| to 2] lines long, the upper third moie membranous, slightly 

 compressed and glabrous, the outer pair of nerves falling short of 

 the apex, awn 1 to 3 Knes ; gl. III. 1| to 2 lines long, resembling 

 gl. II. in texture and hairiness, pale with strongly marked keeled 

 nerves which are ciliolate above ; fertile gl. about 11 line long, 

 lodicules truncately obcuneate, yellow, anthers yellowish-brown, a 

 little over 1 line long. 



A very distinct species, perhaps nearest T. Wightii Nees, from 

 which however it is easily distinguished by its very characteristic 

 habit, minute outer glume, and blunt barren glumes. 



PuNGO AxDONGt). — Perennial, widely cajspitose, culms simple at 

 the base, branched towai'ds the apex, slender, leaves spreading, hairy, 

 the older becoming purple. On the higher rocks of the presidium ; 

 April and May 1857. No. 7393. Pedra Cabondo almost on the 

 highest rocks ; May 1857. No. 2718.
