The remarkable structure of the filaments of the stamens of this 
plant is perhaps the chief ground for constituting a new genus of 
it. Our cultivated flowering samples at Kew did not exhibit any 
specially ringent character in the corolla, nor were the ovaries 
three-celled. It is one of Mr. James Drummond's discoveries 
in south-western Australia, and is a pretty greenhouse climber ; 
but the flowers, though golden-red, have not the brilliancy ne- 
cessary to render them showy. It flowered for the first time 
with us in November, 1860, having been reared from seeds sent 
by Mr. Burges from Swan River. At a more favourable season 
of the year the colour may be more vivid. 
Descr. A branching and twining climber, with slender stems, 
and distant, alternate, oblong-ovate, shortly acuminate, penni- 
veined, quite entire /eaves, three to four inches long, acute at 
their base. Pefiole about two inches long. Peduncle terminal 
(in fact the continuation of a branch), bearing a many-flowered 
corymb, with small bracteas on the pedicels. Calyx of five, 
ovate, acute, small, green sepals. Corolla of five golden-red pe- 
tals, with broad, erect claws, placed so close and so erect as to 
form a tube, while the Jamine, which are ovate and very acute, 
FEBRUARY Ist, 1861.
