identical with the typical species ; Wallich, however, regarded it 
as distinct from that plant, making it a variety of C. Blume- 
anum. It differs from the latter in its palate leaves and shorter 
petioles, and from the former in their oblong and more pointed 
form, with a different tomentum and shorter petioles. Its claims 
to rank as a distinct species are strengthened by the considera- 
tion of the far-distant country of its origin, and because the 
two other species are quite local Its branches are covered with 
woolly fulvous tomentum, and its leaves, which are gradually 
narrower from the middle to the apex, are inches long, 6 
inches broad, on a petiole 2| inches long. 
2. Calycocarpum. 
This genus was established byNuttall, in 1838, upon a plant 
of the Western States of North America, the Menispermum Lyoni 
of Pursh. It is well figured in Gray^s ‘ Genera of the United 
States,’ but the details of the putamen and seed are incom- 
plete. It is a slender climbing plant, having deeply cordate 
5-lobed leaves, with sinuated margins, palately fixed upon along 
slender petiole ; the inflorescence is an axillary, elongated, slen- 
der, racemose panicle, nearly as long as the leaf and petiole. 
It differs from all others of the Heterocliniece in having its male 
flowers provided with six sepals, no petals, and 12 free stamens 
in two series ; its female flower has six sepals, six small fleshy 
petals, six sterile stamens, and three or four sessile ovaries, with 
a very short thick style and a multilaciniated spreading stigma. 
Its drupe contains a meniscoid, orbicular, thin, chartaceous pu- 
tamen, globose on the dorsal side, with a sharp apical spine ; it 
is concave on the ventral face, furnished on its margin with a 
number of soft sharp flattened teeth, and along the upper moiety 
of the ventral face with a carinated longitudinal ridge similarly 
toothed ; the hollow of this face forms a concave scutiform con- 
dyle, which protrudes into the centre of the cell, and from its 
upper part is suspended, by a very short funicle, the deeply 
meniscoid seed ; the embryo is enclosed in the middle of nearly 
simple albumen, which is marked on the inner face by transverse 
lines where it is obsoletely ruminated ; the small radicle points 
to the style near the vertex j the cotyledons are flat, foliaceous, 
oval, greatly divaricated ; they partly overlie each other in the 
upper part, but are widely separated in their lower portion, the 
albumen being there correspondingly 2-celled to contain them. 
The genus is therefore marked by very salient characters.
