opacis et in nervis venisque transversis tomentosis ; petiolo lon- 
gissimo, imo torto et tumido, apice paulo incrassato ; racemo 
dependente, simplici, supra-axillari, lougissimo, gracili, tomen- 
toso; floribus majoribus, subvagis, breviter pedicellatis. — 
Java, V. s. 6 in herb, de Boissier (Zollinger, 745) ; in herb. Mus. 
Brit, et Hook. (Horsfield). 
In Zollinger’s specimen, the branchlet is 3 lines diam., with 
intemodes of 5i inches ; the leaves are of a dark green colour, 
8^ inches from the bottom of the basal lobes (or 7f inches from 
the summit of the petiole) to the apex, and 7 inches broad ; the 
petiole, 6 inches long, very tumid, and spirally tortuous at base, 
gradually swelling at the apex ; the slender pendant raceme is 
10 inches long, is bare of flowers for nearly half its length ; the 
alternate pedicels, about 4 lines apart, are 1 line long, and the 
flowers expanded are 4 lines diam. ; the three outer bracteiform 
sepals, covered with reddish hairs, are 1 line long, the six more 
internal sepals are linearly oblong, acute, revolutely expanded, 
2 lines long, - line broad, with membranaceous margins, and are 
scabridly pruinose outside ; the six petals are erect, about It line 
long, with involute margins and apex, thus almost hooding the 
stamens, which are of equal length ; the filaments are fleshy, 
gradually thickening upwards, the oblique anther-lobes being 
introrsely immersed in their summit. In Horsfield’s specimens 
the leaves are. somewhat smaller. 
8. Burasaia. 
This genus, proposed by Du Petit Thouars in 1806 for some 
Madagascar plants, was included with much hesitation in the 
Lardizabalacece by Prof. Decaisne, in his excellent monograph of 
that family,, his doubts being founded on the minute size of its 
flowers, the absence of sterile ovaria in the male plant, its introrse 
anthers, its fertile ovaries having only a single ovule, the coty- 
ledons of its embryo being large, foliaceous, and divaricately 
placed in distinct cells of the albumen — characters quite opposed 
to Lardizabalacece ; but the consideration of its distinctly 3- 
foliolate leaves, and of the seed being invested by a papillose vis- 
cous envelope, preponderated in favour of its position in the 
former family. I believe I was the first to determine its true 
affinity, in my ‘Notes on Menispermacece’ in 1851, when it was 
placed in my tribe Heterocliniem. Lately, however, the authors 
of the new ‘ Genera Plantarum ’ have removed it from that tribe 
without stating their reasons, and with seeming contradiction 
have placed it in a doubtful position at the tail of the Pachy- 
gonecB, acknowledging at the same time the conformity of its em- 
bryo with that of the Heterocliniece ! After the publication of my
