Following is a translation of the original :

axillary or almost simple. Calyx campanulate, follicles elongate-stipitate. Eastern extra-tropical 
Australia, 1803-4. 
f 
Bentham later on described the species (as a Sterculia) in the following words : 
A tree of from 20 to 60 feet, quite glabrous except the flowers. 
Leaves on long petioles, glabrous and shining, either entire and from ovate to ovate-lanceolate, or 
more or less deeply 3 or rarely 5 lobed, the two lateral lobes sometimes very short, sometimes 
all lanceolate, 2 or 3 inches long, the simple leaves or their lobes always ending in long points. 
Flowers in axillary panicles, rarely exceeding the leaves. 
Calyx very broadly campanulate, slightly tomentose when young, attaining when fully out 7 to 
9 lines diameter, acutely lobed in the middle, of a yellowish white and glabrous except the 
ciliate margins outside, reddish and glabrous within. 
Staminal column also glabrous. 
Ovary slightly tomentose. 
Follicles very ovoid, li to 2 or even 3 inches long, thick and glabrous, on stalks of 1 to 2 inches, 
the endocarp and outer coating of the seeds very shortly hirsute and cohering. (B.F1. i, 
229, as Sterculia diversifolia G. Don.) 
Botanical Name. Brachychiton, already explained, Part LXII, p. 39; 
populneum, Latin, pertaining to a poplar tree, as the tree reminded the describer of 
a poplar. 
Vernacular Names. The " Kurrajong " (variously spelt in old works, Corry- 
jong, Curry jung, and there are other variants). It is of aboriginal origin, and signifies 
bark-fibre. It has long been part of the English language, and the other names 
employed in Australia for this tree arc, by comparison, insignificant.
