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.
