(Puates XXII. & XXIII.) 
DunrsG the last few years our resident English collectors have 
worked energetically in the exploration of the botany of Mada- 
gascar, principally of the elevated central provinces. In the 
* Journal of Botany’ for 1882 I described a selection of the prin- 
cipal novelties sent home by the Rev. R. Baron and Dr. Parker 
up to the autumn of 1881. Since that date several fresh boxes 
have arrived from Mr. Baron, carrying up his eollecting-numbers 
to above 2100; and Dr. Parker, who is now in England on 
account of his health, has brought home a considerable quantity 
of additional material. The present paper contains a notice of 
the most interesting Polypetale which these new contributions 
include, with a few additions from other sources. Type specimens 
of all the novelties described will be found in the Kew Herba- 
rium, and a large number of them also at the British Museum; 
and I hope at some future time to deal with the Monopetale, 
Incompletz, and Monocotyledones of the same collections. 
THALAMIFLORE. 
CLEMATIS DISSECTA, N. sp. 
Scandens, ramulis gracillimis apice pilosis, foliis trifidis petiolatis seg- 
mentis deltoideis decompositis lobis ultimis parvis linearibus acutis, flori- 
bus solitariis axillaribus longe pedunculatis, pedunculis folio subequilongis, 
sepalis oblongis margine tomentosis, staminibus quam flos duplo brevi- 
oribus, carpellis dense albo-pilosis. 
A climbing shrub, with very slender branchlets, pilose only 
towards the tip. Leaves opposite, petioled, tripartite, glabrous, 
each division deltoid, under an inch long and broad, with a petio- 
lule nearly as long as the lamina, the ultimate segments lanceo- 
late, acute, j-Lin.long. Flowers solitary, on ascending axillary 
peduncles about as long as the leaves, with a small compound 
bract below the middle. Sepals oblong, above 3 in. long. Sta- 
mens half as long as the sepals; filaments flattened, pilose ; 
anthers oblong. Carpels in the flowering stage as long as the 
stamens; the ovary and lower part of the style densely pilose.
