Other portions of the calyx ; and should this genus be 
adopted by future botanists, a second species has been re- 
cently 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 En- 
deavour River, and on the North-west Coast; at Port 
Jackson, and at the southern extremes of Van Diemen’s 
Land. 
Dilleniace^. — To that Australian portion of the order 
lately enumerated by M. Decandolle, the present Herbarium 
offers, in addition, only two species of the genus Hemi- 
stemma 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. Lechenaultii of Decau- 
dolle, 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 cer- 
tain 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 ob- 
served on these coasts, that were more particularly inves- 
tigated during the progress of the late voyages ; but as these 
several plants form portions of orders so extremely limited.
