CHARACTERS OF SOME GNAPHALIOID COMPOSITÆ. 153 
pappo inæqualiter lobato coroll tubum subæquante. (Ic. Pl. 
tab. ined.) 
Swan River, Drummond, 1846, 1848.—Stem a foot or more in height. 
Glomerule from one-half to two-thirds of an inch in diameter, its con- 
spieuous foliaceous involucre shorter than the disc. Capitula very 
densely crowded, closely sessile on the much dilated convex receptacle, 
the scales nearly glabrous, as long as the corolla, their tips yellowish. 
Corolla much thickened and indurated at the base after anthesis, and 
the base of the style bulbous, as in Skirrophorus. The achænia have a 
thick, cellular, diaphanous pellicle, which, when moistened, swells into 
an extremely thick gelatinous covering. 
2. C. gymnocephalus, n. sp.: folis lineari-filiformibus cauleque gracil- 
limo cito glabris; glomerulo ovoideo squamis brevissimis inconspi- 
cuis lanceolatis margine scariosis paleis fere similibus eincto; recep- 
taculo angusto cylindrico; achænio hirsuto ; pappo brevi margine 
subintegro. (lc. Pl. tab. ined.) 
Swan River, Drummond, 1848.—Stems a foot or eighteen inches 
high; the leaves an inch or more in length, very narrow. Glomerule 
4 or 5 lines in diameter, globose, or at maturity ovoid, apparently 
naked; the general involucre so small and similar to the paleæ that it 
might escape notice. Except in this respect, and in the different shape 
of the receptacle, however, the floral structure accords with the pre- 
ceding species. The two form a genus well distinguished among the 
Angiantheæ by the calyciform pappus, and of a different habit from 
any other, except Pycnosorus, Benth., which has no involucre, more 
than one-flowered heterogamous capitula, and a very different pappus.
