C. AMARANTACEiE. 
[Ptilotus. 
the upper ones much smaller. Spikes nearly globular, fully |in. diameter, 
numerous, sessile or shortly pedunculate, terminal or in the upper axils, usually 
with one or two small herbaceous leaves close under them. Bracts and 
bracteoles thinly scarious, white and shining, very broadly ovate or almost 
orbicular, obtuse, loose or spreading, 24 to 3 lines long. Perianth not 2 lines 
long, the base a very short open disk, the segments with a narrow base densely 
clothed outside with long woolly hairs, glabrous inside, the lamina or upper 
half rather broader obtuse (pink ?) and glabrous. Stamens all perfect and nearly 
equal in the flowers examined. Ovary glabrous. — F. v. M. Fragm. vi. 232.

5. TRICHINIUM, R. Br. 
(From trichinos, covered with hairs). 
(Goniotriche, Turcz ; Hemisteirus and Arthrotrichum, F. v. M.). 
Flowers hermaphrodite. Perianth with a short turbinate hard tube, reduced 
sometimes to a slight expansion of the peduncle ; segments 5, all equal or the 
three inner ones rather smaller, linear, rigid, usually 3-ribbed at the base, scarious 
at the tips or also along the margins of the upper portion, covered outside either 
entirely or rarely along the centre only with straight more or less distinctly arti- 
culate (several-celled) hairs giving them a plumose appearance, the short tips 
alone glabrous. Stamens normally 5, but usually 1, 2, or 3 of them small and 
without anthers, or entirely abortive, and all the filaments unequal, or more 
rarely all equal and antheriferous, united at the base in a membranous cup adnate 
to the perianth-tube or shortly free from it, without or rarely with intervening 
scale-like teeth or lobes, which when present, are very thin and transparent ; 
anthers 2-celled. Ovary uniovulate. Style simple, rigid, wflth a small capitate 
stigma. Fruit an indehiscent utricle, usually obovoid or contracted into a stipes 
at the base and oblique at the top, with the persistent style more or less excen- 
trical. Seed vertical. — Herbs undershrubs or rarely shrubs, glabrous or hairy 
with crisped articulate woolly or stellate hairs. Leaves alternate, narrow or 
rarely obovate. Flowers in dense globular ovoid or cylindrical spikes, very rarely 
elongated and interrupted. Bracts and bracteoles scarious and shining, nerveless 
or with a more or less prominent midrib produced into a fine or short point. 
Perianths usually pink or straw-colour. Stamens and ovary often enveloped in 
dense wool or long hairs proceeding either from the lower part or claws of the 
inner perianth-segments or from the outside of the staminal cups. 
The genus is limited to Australia. 
Series I. Astrotricha. — Foliage hoary or white with a stellate tomentum (glabrous or 
with crisped or woolly or silky hairs in all the other series). 
Spikes dense, globular ovoid or shortly cylindrical, not exceeding lin.

Spikes ovoid, at length cylindrical. Bracts glabrous or slightly 
woolly 2. T. parvi/lorum.

stellate hairs short and scattered 3. T. dissiti/lorum. 
Series II. Straminea. — Sjnkes cylindrical or elongated or rarely globular, 1 to 2in. 
diameter. Flowers more or less yellow or greenish, not red. Inner segments without internal 
dense wool, but the stamens ustially surrounded by a few long hairs. 
Spikes elongated with distant flowers. Leaves filiform 4. T. distans. 
Spikes dense, at length long and cylindrical. 
Leaves linear. Bracts wholly transparent. Bracteoles broad without 
prominent midribs. Perianth under fin 5. T. alopecuroideum.
