Root undivided, slender, often flexuose, a few inches long. 

 Stems a span long .or shorter, spreading-branched, slightly 

 scabrous. Leaves alternate, very narrow linear, curved, in 

 consequence of their revolute margins filiform, \-l inch long, 

 awnless. Peduncles more or less shorter than the involucre, 

 which is 4-5 lines long ; its scales in a few rows, green, at 

 last brownish, sessile, with scarious margin, glabrous, the 

 outer ones very short, the inner ones gradually longer, the 

 innermost linear and running out in a subulate acumen. 

 Receptacle very small, convex, tubercled. Corollas about 2 

 lines long, whitish; female ones extremely thin, with widened 

 base, their ligules two-toothed, shorter than the capillary 

 branches of the style. Hermophrodite corollas filiform ; their 

 style short-exserted, undivided. Fertile acheniums scarcely 

 longer than one line, with attenuate base and truncate sum- 

 mit ; their pappus 2 lines long, brownish-yellow. Barren 

 acheniums diminute. 



Calotis plumulifera. 



(Sect. Acantharia.) 



Annual, dwarf, slightly hispid ; stem erect, branched; leaves 

 oblong-lanceolate, perfectly entire or remotely toothed, 

 tapering at the base, the upper ones sessile ; flowerheads 

 small, pedunculate ; scales of the involucre lanceolate 

 acute ; receptacle conical ; ligules white ; acheniums on 

 both sides woolly with plumose downs, at the margins 

 expanded into an acutely dilated wing, which is fringed 

 with feathery hair ; awns numerous, capillary, shorter 

 than the achenium or nearly as long as it, unequal, in 

 their whole length ciliated by short spreading or re- 

 curved hair. 



On the Murray plains. 



An herb 2-4 inches high, with the habit of a Brachycome. 

 Root thin, simple, flexuose. Leaves ^ to § of an inch long, 

 1-2 lines broad. Peduncles axillary and terminal, sometimes 

 an inch long, often shorter, bracteate by one or the other, 

 small leaf. Flowers in each head numerous ; the inner ones 

 about 1 line long, perfectly barren, although hermaphrodite, 

 with undivided style ; the outer ones varying from 10 to 20 

 in number, of which some are occasionally abortive. Ligules 

 with a lamina 1-1^ line long, \-% line broad. Achenium- 

 wings with a sinus descending from the vertex to the outer 

 or middle point, thence tapering wedge-like, glabrous on
