to Triraphis, a view I should adopt in this Manual were it not for the 
convenience of as close adherence as possible to the nomenclature of 
the Flora Australiensis. 
Botanical description (B. Fl. vii, 605). An erect cali grass of 
2 or 3 feet. 
Leaves narrow, flat, or convolute. 
Panicle very loose, with long capillary branches, bearing each one to three large flat 
spikelets on capillary pedicels, at first erect, at length pendulous. 
Spikelets ten- to fourteen-flowered, # to 1 inch long, the rhachis with a tuft of short 
hairs under each flowering glume. 
Outer empty glumes narrow, acute, keeled, with or without a faint nerve on each 
side. 
Flowering glumes distant from each other, about four lines long, rigid with five very 
prominent nerves of which the three principal ones produced into short terminal 
points or teeth, the central one rather the largest. 
Value as a fodder—Unknown; not likely to be important, on 
account of its rarity. It may also be mentioned that its affinities are 
with two genera not distinguished for yielding nutritious grasses. 
Habitat and range.—Confined to New South Wales, and only 
recorded from the Blue Mountains. It is one of the rarest of our 
gTasses. 
Reference to Plate.— A. One of the flat spikelets enlarged and opened out. 3B.c. Two 
pairs of glumes, showing a tuft of short hairs under each flowering glume. op. End of a 
flowering glume, with its five prominent nerves, three of which are produced into short 
terminal points. 
70. TRIODIA. 
Spikelets several-flowered, paniculate, the rhachis articulate above 
the outer glumes and between the flowerimg ones, hairy round them 
or glabrous. 
Glwmes unawned, two outer empty ones acute, keeled, glabrous or 
the keel scabrous-ciliate. 
Flowering glumes usually shorter, unawned, the lower part rounded 
on the back, more or less three-nerved at first, often hardened and 
nerveless in fruit, with three terminal one- or three-neryed lobes or 
teeth. 
Palea about as long as the entire part of the glume, with two 
prominent nerves. Ovary glabrous. 
Styles very short, distinct. 
Grain somewhat dorsally compressed, enclosed in the glume and 
palea, free from them. 
Leaves very pungent, the sheaths usually viscid; flowering glumes 
silky-ciliate, divided nearly to the aaa into three lobes. 
Panicle loose and spreading ; spikelets dark, 4} inch long, eight- to
