thick and somewhat succulent, three-nerved below; sepals oval, obtuse ; pedun- 
cles solitary, one-flowered; rays short, about eight. 
Has. Near the sea, at Ouau and Atooi. Stems diffuse, procumbent, many from the same pe- 
rennial tortuous root, each spreading out a foot or more, in all directions. Leaves about half an inch 
long, two or three lines wide, strongly nerved beneath, thick and somewhat succulent, pedicels 
two or three inches long. Capituli small, with the sepals obtuse. Scales of the receptacle obtuse, 
and hirsute at the tips as. well as the florets. Fertile achenia short, roundish and angularly trique- 
trous, pubescent at the summit. Pappus rather deciduous, of three or four short linear, or linear- 
lanceolate scales of different sizes, all scarcely visible to the naked eye; tabescent achenia, which 
are numerous, compressed: some of the fertile ones are also often obtusely tetragonal.

Very nearly allied to M. lanceolata, differing ee in the coarsely toothed, 
sessile leaves, and smooth achenium.

Achenium obtuse, with three or four angles, with a coronal pappus of one to 
three deciduous awns. 7

Has. Ouau, near the sea. Herbaceous. Leaves three to four inches long, two to two and a 
half wide, broadly connate, the centre of the connate portion salient, denticulate. Flowers tricho- 
 tomal; pedicels one to three-flowered. Involucrum campanulate, few-flowered, in nearly a single 
series of six to eight oblong-ovate leaves. alee of the receptacle often three-toothed. Achenium 
‘arrow, acutely triquetrous, hispid on the angles; the pappus of three or five very minute scales, 
which are somewhat deciduous; infertile achenia compressed. 
* SCHIZOPHYLLUM. 
Capitulum few-flowered, heterogamous. Rays feminine, two or three, biden- 
tate; discal florets subcampanulate, five-toothed. Involucrum small, oblong, 
imbricate, about five-leaved. Receptacle paleaceous, the scales resembling 
the involucrum, embracing. Discal stigmas hirsute, with a slender conic 
apex. Achenia of the ray turgid, indurated, three or four-sided, obtuse and 
_ turbinate; those of the disk abortive, subquadrangular. Pappus none, or a
