C. AMARANTACEiE. 
[Trichinium. 
Leaves linear or linear-lanceolate, mucronate-acnte, sessile or contracted into a 
petiole, the larger ones 1 to 2in. long, but mostly small and distant. Spikes 
globular or ovoid or rarely at length cylindrical, about lin diameter, on rather 
long peduncles, forming a loose irregular panicle. Bracts and bracteoles broad, 
obtuse, thinly scarious, rather brown but without prominent midribs, not half as 
long as the perianth. Perianth about Ain. long, the segments free almost from 
the base, all nearly equal, and glabrous inside, with broad scarious white margins, 
the green centre alone hirsute outside with articulate hairs much shorter than in 
any allied species. Stamens very unequal, the filaments shortly dilated at the 
base and very shortly united, 1 or 2 of the shorter ones without anthers, 
surrounded by a few woolly hairs proceeding chiefly from their base. Ovary 
glabrous. Style excentrical..— Mcq. in DC. Prod. xiii. ii. 291 ; T. Gaudichaudii,

Hab.: Inland localities. 
Var. parviflora. Perianth scarcely above 4 lines long. 
When the spike elongates, the species bears much resemblance to T. cilojjecuroideitm, but the 
leaves are much narrower, and the shortness o£ the perianth-hairs gives the spike an almost 
glabrous aspect. — Benth. 
9. T. exaltatum (tall), Benth. FI. Austr. v. 227. A stout perennial, with 
a thick stock and erect stems, attaining 2 or 3ft., usually branching in the 
upper portion, glabrous or hirsute with spreading hairs. Radical and lower 
leaves oblong-lanceolate, attaining 3 to 5in., rather thick, contracted into a 
long petiole, the upper ones small, sessile, broad and narrow, often undulate 
or with crisped margins. Spikes erect, on long peduncles, at first ovoid- 
conical, at length oblong-cylindrical, about 2Ain. diameter, Bracts and bracteoles 
rarely half as long as the perianth, ovate-lanceolate, mucronate, scarious with 
a brown midrib and sometimes broadly brown towards the end, the bracteoles 
usually rather shorter than the bracts. Perianth rarely above fin. long and 
sometimes rather shorter, the tube above 1 line long, the segments narrow, 
rigid and almost acute, plumose outside with long articulate hairs, the short 
glabrous tips of a dull red colour, the inner ones with dense wool inside below 
the middle. Stamens unequal, the filaments dilated but scarcely united at 
the base, or 2 of the shorter ones without anthers. Ovary of the Queensland 
plants hairy, contracted into a rather long stipes. — Ptilotus exaltatus , Nees in

10. T. semilanatum (half-woolly), Lindl. in Mitch. 'Prop. Austr. 45; 
Benth. L l. Austr. v. 227. A perennial with a tufted stock and erect simple or 
slightly branched stems of Gin. to 1ft., more or less pubescent as well as the 
foliage with short crisped hairs or quite glabrous. Leaves linear or linear-lance- 
olate, acute, the radical ones not persistent at the time of flowering, the lower 
ones petiolate, 1 to 2in. long, the upper ones more sessile and smaller, the 
margins flat or undulate-crisped. Spikes at first depressed or hemispherical 
at length globular, about lAin. diameter. Bracts about 2 lines long, ovate- 
lanceolate, mucronate, more or less brown in the centre and tips ; bracteoles 
broader, more obtuse and not brown. Perianth about fin. long, the tube 
about f line, the segments narrow, rigid, plumose on the back, with short 
glabrous pink tips ; the inner ones with long wool inside below the middle 
not very copious. Filaments dilated at the base, shortly connate, 1 or 2
