pale yellow or straw colour, the tube exceedingly short, the segments £ to Jin. 
long, narrow, obtuse, but appearing acute from the involution of the margins at 
the tip, the dorsal hairs not so copious as in some species and all glabrous inside. 
Staminal cup shortly prominent, surrounded by long straight hairs sometimes 
very few sometimes copious ; stamens very unequal, one or two of the filaments 
usually short and without anthers. Ovary glabrous. — Moq. in DC. Prod. xiii. ii.

6. T. nobile (notable), Lindl. in. Mitch. Three Exped. ii. 22; Benth. FI. Austr. 
v. 224. A stout erect, glabrous perennial, the stems simple or slightly-branched 
upwards, 1 to 8ft. high. Leaves from broadly obovate to oblong, rarely lanceo- 
late, the lower ones chiefly radical on long petioles, obtuse or mucronate, the 
upper ones narrower and more sessile. Spikes terminal, oblong, attaining 8 to 
6in. in length and nearly 2in. diameter, the rhachis very densely hairy. Bracts 
3 to 5 lines long, ovate or oblong, the midrib prominent and projecting into a 
point, scarious but with a dark centre, especially towards the tip ; bracteoles 
similar but rather smaller and often with a few dorsal hairs. Perianth usually 
about lin. long, of a greenish yellow, the tube 1 to l\ line long and densely 
hirsute with short hairs, the segments narrow, copiously plumose with dorsal 
hairs, the glabrous tips short, obtuse in the outer segments, more acute in the 
inner, all without any wool inside but a few long straight hairs round the base 
of the stamens, which are not united above the perianth-tube, the filaments very 
unequal, and 1 or 2 without anthers. Ovary glabrous. — Moq. in DC. Prod. xiii.

7. T. macrocephalum (long-headed), B. Br. Prod. 415, not of others ; Benth. 
FI. Austr. v. 225. Stems from a hard perennial base erect or ascending, simple 
stout and rigid, 1 to 2ft. high, usually glabrous as well as the foliage. Leaves 
few at the base of the stem, linear or narrow-lanceolate, acute or rarely obtuse, 
contracted into a long petiole, 2 to 4in. long, the upper ones smaller few and 
distant. Spikes solitary, at first ovoid, at length cylindrical, attaining 4 or 5in. 
in length and at least 2in. diameter. Bracts scarious and very shining, obtuse 
or muconate, without prominent midribs or dark colour, about Jin. long and the 
bracteoles nearly as large. Perianth yellow, f to above lin. long, the tube very 
short, the segments narrow, rigid, densely plumose outside, with short glabrous 
tips, all nearly equal without any internal wool, although a few of the marginal 
hairs at the base of the inner ones may be turned inside round the stamens. 
Filaments very unequal, filiform scarcely dilated at the base, very shortly united 
above the perianth-tube, and surrounded by a few long hairs, the shorter filaments 
usually without any anther. Ovary glabrous, but a few hairs often on the style.
