452 DESCRIPTIONS OF NEW SPECIES 



thick and somewhat succulent, three-nerved below ; sepals oval, obtuse ; pedun- 

 cles solitary, one-flowered; rays short, about eight. 



Hab. 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. 



MicroclicEta procumhens. Wollastonia procumbens, Decand., Vol. V., p. 548. 

 Very nearly allied to M. lanceolata, differing principally in the coarsely toothed, 

 sessile leaves, and smooth achenium. 



Microchceta strigulosa. WoUastonia strigidosa, Degand., Vol. V., p. 548. 

 Achenium obtuse, with three or four angles, with a coronal pappus of one to 

 three deciduous awns. 



f Leaves co?inate, perfoliate; flowers paniculate, trichotomal; pappus minute. 



MicrochcBta connata. Lipochceta connata, Decand., Vol. V., p. 611. Vei'he- 

 sina connata, Gaudichaud, in Freycenet's Voyage, p. 464. 



Hab. 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. Palese of the receptacle often three-toothed. Achenium 

 narrow, 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 

 slight vestige of an aristate crown. — An herbaceous plant of the Sandwich
