fragments remaining- about the fiuits seen by R. Brown, in wliich he aseer- 

 tained that the calyx was lobed and the stamens numerous. Capsule (always?) 

 S-celled, the wings broadly obovate, about i in. long, simiate-crenate on the 

 margin. Seeds 1 or 2 in each cell. 



Queensland. Cuiuberhuid TslauJs, i?, £row7i (lid, R. Br.). The shape of the fruit 

 anJ its wings and the seeds are the same as in the Asiatic B. Jmmoniiia, Koxb., DC. Prod. 

 1. o]7, Wight, 111. t. 34 ; but as that species has acuminate leaves and a 3-celIed capsule, 

 I had at first thought that this one might be distinct. 1 find, however, some Ceylon spe- 

 cuuens with tlie same rounded leaves, and the Australian specimens are not sufficient 

 to show whether the reduced number of carpels Is more than accidental.

Sepals 5, distinct. Petals 5, with a foveola or thickened cavity at the 

 base, usually shorter than the calyx, inserted round the l)ase of the torus, 

 otameus indefinite, inserted on the raised torus. Ovary 2- to 4-celled, 

 with 2 or more ovules in each cell ; style subulate, minutely toothed or lobed. 

 Drupe containing 1 to 4 pyrenes or nuts, entire or 3- or 4-lobcd, the nuts 

 either 1 -seeded or 2- or more seeded, and then divided by transverse parti- 

 tions between the seeds. Seeds ascending or horizontal, the albumen usually 

 copious, the cot^yledons flat. — Trees or shrubs, the hairs or toinentum stellate. 

 -Leaves entii'e or serrate, 3- to 7-nerved. Stipules narrow, deciduous, 

 r lowers usually yellow, the umbel-like cymes axillary or terminal. 

 Australian species (except G. brevljlora) the ovary is 2-cellcd, but c^ 

 subdivided by a vertical, nearly complete partition, so as to appear 4-cellcd, 

 with two or rarely more superposed ovules in each half-cell, each half-cell 

 iormnig iu the fruit a separate nut, with ] or rarely more superposed seeds in 



The genus is a large one, widely spread over the tropical and subtropical regions of the 



Old World. Of the Australian species, 3 extend over tropical Asia, the remaining 5 are 

 endemic.
