AND GENERA OF PLANTS. 451 
tabescent, compressed and linear. Pappusa short, persistent, or somewhat 
deciduous crown of two or three to five unequal, or nearly equal, short, acute 
palez, longer and fewer in the infertile fruit—Suffruticose or herbaceous 
plants, chiefly of the Sandwich Islands and Australasia, with opposite, ovate, 
dentate or incisely lobed leaves; flowers terminal, or subumbellate, peduncu- 
late, yellow. In habit allied to Wedelia and Wollastonia. With a different 
involucrum, achenium, receptacle and pappus from Lipocheta umbellata, 
with which I have compared our plants. 
Microchetal obata; 8. hastulata. Lipocheta hastulata, Decanp., Vol. V., p. 
161. Verbesina hastulata, Hoox. and Arnort, Bot. Beechy, p. 87. 
Has. In the island of Ouau and Atooi. A low suffruticose plant, with the leaves more or less 
lobed, sometimes nearly entire. Pappus of the tabescent florets (in an early stage,) with two awns, 
much shorter than the fiuit, connected with a membranous, lacerate, minute cup. Involucrum sub- 
campanulate, in almost a single series of hroad ovate, leafy sepals. Rays about ten. Capituli 
sometimes solitary. Leaves ovate, or oc » cowhat acuminate, the base often in- 
cisely one or two-lobed on either side; the ster: pW... .ounte at base. 
Microcheta *lanceolata; herbaceous; stem angular, decumbent, dichotomous; 
leaves shortly petiolate, lanceolate or ovate-lanceolate, scabrous and strigose, 
entire and very acute, distantly serrate, the serratures shallow, appressed and 
mucronate; uppermost leaves alternate; peduncles solitary, dichotomal or ter- 
minal, in twos and threes; involucrum rather flat and hemispherical; a , 
short and numerous. 
‘Has. In Ouau, near the sea, Branches long and trailing, prostrate and ascending: the leaves 
three-nerved, attenuated into a short petiole. Pedicels elongated, naked: sepals ovate, strigosely 
hirsute, ten, in about two equal series. Rays as short as the involucrum, about twenty. Palee 
of the receptacle ovate above, hirsute, often three-toothed. Fertile achenium oval, turgid, trique- 
trious and scabrous, with salient angles. Pappus a small persistent crown of three to five minute 
palez united in the centre of the contracted summit into a sort of cup: in the tabescent achenia 
(which are very numerous,) the fruit is narrow-linear, with the palez arising, as it were, from the 
angles.
