A reiy slender, imich-branched plant, 2 -8 inches high, more or less laxly tomentose or nearly glabrous.
Stems and branches filiform. Leaves petiolate, pinnatifid or subbipinnatitid; the segments linear, spreading, rather
remote, acute. Peduncles very slender. Capitula minute, | inch aci-oss. Florets o f the ray stipitate, iu several
series, broadly oblong, winged, notched at the top or with a rudimentary corolla round the base of the style, iimei'
or both surfaces o f the achenium glandidar.— This has been referred to the genus Pleiogyne o f Kaid Koch (Bot.
Zeit. i. 39, Jan. 1843) along with other allied species, characterized by having several rows of ray-flowers, and few
disc o n e s ; also by the disc flowers being more or less steiile, aud their corolla not w in g ed ; but the numbers and
proportion of these varies so much in tbe different species, that it appears to me to be luulesirable to dismember
the old genus Cotula on this account, and the disc flowers of all are more or less compressed, it' not winged. De
Candolle is in error in his characters o f Strongylosperma, ascribing to it ligulate-marginal flowers.— P l a t e h .A .

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, axiltarj', shorter than the leaves. Capitula small. Involucral scales broad, herbaceous, in two series,
glandular. Flowers o f ray in several series, shortly stipitate, oblong, with ciliated wings, and no corolla. Floweis
of the disc tubular, four-tootlied, male, with a short, truncate style, not cleft at the summit.— I have suppressed
the genus Ctenosperma, which I established upon this plant, a more extended examination of the species o f Cotula
having shown me that if the characters I had employed for separating it arc considered o f generic value, it will
lead to the dismemberment of one very natural genus, and the construction of others witli no good distinguishing
characters.— P l a t e LI. Fig. 1, capitulum; 2, ditto, showing the receptacle; 3, flower of disc; 4 , stamen;

This cm-ious genus is confined to New Zealand, Tasmania, Southern AustraUa, Lord Auckland^ and Campbell’s
Islands, Kerguelen’s Laud, and Fuegia, whence eight or ten species are known, of which three or four are Australian.
The most peculiar character consists in the frequently inflated flowers o f the ray, whose corolla is formed of
two layers, with an intervening hollow space (see ‘ Flora Antarctica,’ p. 28). As a geuus it is perhaps hardly distinguishable
from Cotula, in which the flowers of the circumference have sometimes an imperfect coroUa, and only a
ve iy short stipes; the achenia are however usuaUy more winged in the AustraUan species o f Cotula. All the Tasmanian
species have very few involucral scales, whence I proposed (Lond. Jom-n. Bot.) that they shoidd be included
in a subgcnus, Oligoleima.— Creeping, monoecious or dioecious herbs, often throwing out rooting suckers, smooth,
silky, or wooUy, with scapes bearing soUtary, yellow, inconspicuous heads, which have no ray, and are buttonshaped.
Leaves pinnatifid. Involucral scales in one or many series, broad, with a membranous, brown or puiplish
edge. Receptacle convex or conical, naked, papiUose. Flowers all sessile or shortly stipitate, those o f the ehcum-
ference numerous, in many series, female. Cwolla short, compressed, inflated, tubular, ivith a contracted, small,
truncate or four-toothed mouth. Style exserted, bifid. Achenium obovate, compressed, with thickened wings aud
no pappus. Flowers of the disc hermaphi-odite, tubular, w itb a fom--tootbed coroDa, and a style ending in a cup or
disc. Achenium abortive. (Name, tbe diminutive of X c ttto ;, slender; in ahusion to the liabit of the species first
