glumes and a fertile glume markedly longer than, not subequal to: 
its pale. 
Punco ANDONGU.—A fine grass, cespitose, 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 cespitose, shoots decumbent-ascending, simple 
or sparsely branched below, more or less densely branched to- 
wards the apex ; Jeaves 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, hairs appressed, silky, shining-white tipped 
with purple; glume I. at the base of gl. III. minute, hairy; 
gl. IT. 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 ¢ 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 more high, shoots densely tufted, internodes. 
short, enveloped in the leaf-sheaths, leaf-blades ? to 1% 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 slender 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. 
12 to 24 lines long, the upper third more membranous, slightly 
compressed and glabrous, the outer pair of nerves falling short of 
the apex, awn 1 to 3 lines; gl. III. 12 to 2 lines long, resembling 
gl. Il. in texture and hairiness, pale with strongly marked keeled 
nerves which are ciliolate above; fertile gl. about 1} line long, 
lodicules truncately obcuneate, yellow, anthers yellowish-brown, a 
little over 1 line long. 
A very distinct species, perhaps nearest 7’. Wightii Nees, from 
which however it is easily distinguished by its very characteristic 
habit, minute outer glume, and blunt barren glumes. 
Punco ANDonGo.—Perennial, widely cxspitose, culms simple at 
the base, branched towards 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.
