1 ( J2 FLORA OF TASMANIA. [Composites. 
Disteib. South-eastern and South-western % Australia, New South Wales, New Zealand, Tristan 
d'Acunha, (Cape of Good Hope?). (Cultivated in*England.) 
A very slender, much-branched plant, 2-8 inches high, more or less laxly tomentose or nearly glabrous. 
Stems and branches filiform. Leaves petiolate, pinnatifid or subbipinnatifid ; the segments linear, spreading, rather 
remote, acute. Peduncles very slender. Capitula minute, £ inch across. Florets of the ray stipitate, in several 
series, broadly oblong, winged, notched at the top or with a rudimentary corolla round the base of the style, inner 
or both surfaces of the achenium glandular.— This has been referred to the genus Pleiogyne of Karl Koch (Bot. 
Zeit. i. 39, Jan. 1843) along with other allied species, characterized by having several rows of ray-flowers, and few 
disc ones ; also by the disc flowers being more or less sterile, and their corolla not winged ; but the numbers and 
proportion of these varies so much in the different species, that it appears to me to be undesirable to dismember 
the old genus Cotula on this account, and the disc flowers of all are more or less compressed, if not winged. De 
Candolle is in error in his characters of Strongylosperma, ascribing to it ligulate marginal flowers.— Plate L. A.

3. Cotula integrifolia (Hook, fil.) ; pusilla, glaberrima, eaule simplici filiformi parce foliato, foliis 
linearibus integerrimis, pedunculo solitario filiformi, capitulis minimis, fl. radii paucis 2-3-seriatis longe 
stipitatis, achenio late alato apice bifido, corolla 0. {Gunn, 1153.) (Tab. L. B.) 
Hab. Moist ground near Georgetown, growing intermixed with Desvauxia and other plants, Gunn.— 
(Fl. Nov.) 
A very minute, slender, inconspicuous plant, 1-2 inches high. Stems erect, weak, slender, unbranched or once 
or twice divided. Leaves linear, quite entire, very narrow. Peduncles very slender, solitary. Capitula very small. 
Involucral scales almost orbicular. Floicers very few.— Plate ~L.B. Fig. 1, capitulum; 2, involucral scale; 3,

breve petiolatis pinnatifidis segmentis subremotis linearibus acutis integerrimis v. margine superior* 1-2- 
dentatis, pedunculis brevibus crassis, iuvolucri squamis glandulosis, ncheniis radii pluriseriatis breviter sti-

Hab. Subalpine and alpine situations in damp ground, Marlborough, etc., Gunn.— (F\. Jan.) 
Distrib. Victoria (Cobboras Mountain, elev. 5-6000 feet), Mueller. (Cultivated in England.) 
A perfectly glabrous, procumbent, very herbaceous, stout little species.— Root of thick, fleshy fibres. Stems 
many, spreading, 1-3 inches long, branched leafy. Leaves A-f inch long, petioled, pinnatifid. Peduncles short, 
very thick, axillary, shorter than the leaves. Capitula small. Involucral scales broad, herbaceous, in two series, 
glandular. Motpen of raj in several series, shortly stipitate, oblong, with ciliated wings, and no corolla. Flowers 
of the disc tubular, four-toothed, male, with a short, truncate style, not cleft at the summit.— I have suppressed 
the genus Ctmosperma, which 1 established upon this plant, a more extended examination of the species of Cotula 
having shown me that if the characters I had employed for separating it are considered of generic value, it will 
lead to the dismemberment of one very natural genus, and the construction of others with no good distinguishing 
characters.— Plate LI. A. Fig. 1, capitulum; 2, ditto, showing the receptacle; 3, flower of disc; 4, stamen;
