short and without anthers. Ovary hairy on the top. — Moq. in DC. Prod, 
xiii. ii. 462; T. pulchellum A. Cunn. and F. setigerum , A. Cunn.; Moq., l.c.

Hab.: Head of the Gilbert River, F. v. Mueller; Wide Bay, Bidwill ; Rockhampton, 
O’Shanesy ; Midge Creek, Bowman; Warwick, Beckler ; Darling Downs, Lau. Very abundant 
on Downs country. 
The species is very near T. exaltation, from some species of which it is difficult to distinguish 
it. The spikes, however, are always shorter, the bracts smaller and more scarious and the 
foliage different. — Benth. 
11. T. Burtonii (after R. C. Burton), Bail. Bot. Bull. 2. A perennial 
with a hard tufted stock. Stems sulcate, slightly hairy in decurrent line s 
from base of leaf, and more or less densely woolly-hairy near the inflorescence. 
Radical leaves about ljin. long including the rather long petiole, obovate 
or broadly spatliulate, and prominently mucronate, the lamina decurrent on 
the petioles, expanding and stem-clasping at the base. Stem-leaves much 
smaller of somewhat similar form, nearly sessile, the apex pungently mucronate. 
Spikes at first ovoid-conical, at length cylindrical, still with a conical apex, 
attaining 3 or more inches in length, and a diameter of l|in. Bracts and 
bracteoles lanceolate, about one-third the length of perianth, scarious and 
more or less dark coloured, both acutely acuminate, but the bracteoles not 
so dark and rather less than the bracts. Perianth fin. long, the tube 
slightly turbinate, very short, hirsute with long hairs outside ; segments 
narrow, rigid, with obtuse glabrous rosy tips about 1 line in length, the 
remainder plumose outside with long articulate hairs, the hairs of the 
margins near the base very long and flexuous, covering the inner surface, 
which, however, is glabrous. Filaments dilated at the base but not united 
above the perianth-tube in any of the flowers examined, 2 reduced to 
staminodia. Anthers rather large, oblong. Ovary shortly stipitate, glabrous 
except the top, which is woolly-hairy. Style excentrical, quite glabrous, 
pink towards the small brown stigma. Seed glossy.

12. T. fusiforme (spindle-shaped), B. Br. Prod. 415; Benth. FI. Austr. 
v. 234. A perennial with a fusiform rhizome and slender erect branching stems 
of 1 to 2ft. Leaves narrow-linear or almost filiform, the lower ones often 2in. 
long, the upper ones few small and distant. Spikes ovoid, about lin. diameter, 
on long slender branches or peduncles. Bracteoles broad, very obtuse, closely 
enveloping the perianth, very thin and shining, about 2 lines long, the bracts 
shorter and more acute. Perianth 5 to 6 lines long, the segments free almost or 
quite to the base, narrow, rigid, 3-nerved, plumose outside with rather rigid long 
hairs, with short glabrous tips rather longer and more obtuse in the outer than 
the inner segments, all glabrous inside. Staminal cup very short, densely 
covered outside with long straight hairs ; filaments unequal, all antheriferous or 
one without an anther. Ovary densely hairy. — Moq. in DC. Prod. xiii. ii. 294 ;

13. T. gracile (slender), R. Br. Prod. 415 ; Benth. FI. Austr. 235. Very 
near T. fusiforme, and the structure of the flowers the same, but an annual with 
still more slender branching stems, the leaves filiform, the spikes globular not 
above fin. diameter, and the perianth only about 4 lines long with much shorter- 
glabrous tips. — Moq. in DC. Prod. xiii. ii. 294 ; Ptilotus gracilis, Poir. Diet.
