lk of Adansonia of
the western shores of Africa. At the respective period of visiting those
parts of the North-west Coast, this gouty tree had previously cast its
foliage of the preceding year, which is of quinary insertion, but it bore
ripe fruit, which is a large elliptical pedicellated unilocalar capsule
(a bacca corticosa) containing many seeds enveloped in a dry pithy
substance. Its flowers, however, have never been discovered, but from the
characters of the fruit, it was (upon discovery) referred to this natural
family. M. Du Petit Thouars has formed a new genus of Capparis
pauduriformis of Lamarck, a plant of the Island of Mauritius, which he
has named Calyptranthus. It has one division of the calyx so formed, that
by its arcuated concavity (before expansion) it conceals the whole
flower, and the other portions of the calyx; and should this genus be
adopted by future botanists, a second species has been recently
discovered upon Dirk Hartog's Island, although of remarkably different
habit.

Cleome has been observed only in the equinoctial parts of Australia, and
like Capparis, several species exist on the North-west Coast, being
limited to C. viscosa in New South Wales.

Drosera, which Jussieu associates with these genera is generally
diffused, being found within the tropic, at Endeavour River, and on the
North-west Coast; at Port Jackson, and at the southern extremes of Van
Diemen's Land.

DILLENIACEAE. To that Australian portion of the order lately enumerated
by M. Decandolle, the present Herbarium offers, in addition, only two
species of the genus Hemistemma of M. Du Petit Thouars. The one
discovered on the North-west Coast, and allied to H. angustifolium of Mr.
Brown; the other proving also new, but approaching in character the
doubtful species, H. leschenaultii of Decandolle, and was discovered upon
Rottnest Island, off the western coast of the continent, and is the first
certain species of the genus, that is not limited to a tropical
existence.

In addition to what has been advanced in respect to certain natural
orders that appear in the Herbarium, formed under the stated
circumstances, a slight mention might be made of other detached genera,
or families sparingly observed on these coasts, that were more
particularly investigated during the progress of the late voyages; but as
these several plants form portions of orders so extremely limited, and in
themselves presenting nothing remarkable in their inte
