MALVACEiE, Juss. Tiliaceae, Juss. Sterculiaceae, Vent. 
Buttnericeae, Brown , — These several families, of which the 
first is by far the most extensive, have been viewed by Mr. 
Brown, as so many allied orders of one natural class, to 
which the gfeneral title of Malvaceae might be applied. 
About thirty-six species of these orders collectively, are 
preserved in the present Herbarium, referrible at least to 
eleven genera, of which nine are most abundant in (and 
form a characteristic feature of) the botany of India, and 
the equinoctial parts of South America. Fourteen species 
of Hibiscus and Sida were observed on the intratropical 
Coasts of Australia, beyond which also, on the opposite 
shores of the continent, each genus has been remarked. 
One species of Bombax with polyandrous flowers, and sub- 
sphserical obtusely pentagonal capsules, was discovered 
upon the East Coast, in about latitude 14° South, and on 
nearly the western extreme of the same parallel, it appeared 
much more abundant. Of Sterculia which is scarcely to be 
found beyond the tropics in other countries, a species exists 
in New South Wales in the latitude of 34°, on which pa- 
rallel it is more frequent in the western interior, and in that 
direction it has been traced to the distance of three hundred, 
miles from the sea-coast., The genus is also found on the 
North and North-west Coasts, where the species assume 
more particularly the habits of their congeners in India. 
Among the plants of this family in the Herbarium is a spe- 
cies of Helicteris (as the genus stands at present) which was 
observed on the North-west Coast bearing fruit, wanting 
the contortion that characterizes the genus. 
This plant, together with three other described species, 
having straight capsules, may hereafter be separated from 
that Linnean genus, and constitute a new one of themselves. 
Grewia, Corchorus, Triumfetta, and Waltheria, have been ob-
