Said to be native of the newly discovered territory on the 
inland side of the Blue Mountains in New South Wales; 
and now first introduced by Messrs. Colvill, of the Chelsea 
Nursery, King’s Road. It has a lively showy appearance 
in flower, and proves a valuable addition to our green- 
houses. 
Quite smooth in every part: branches trailing, vimine- 
ous, numerous, slender, angular, leafy. Leaves loosely 
scattered, sessile by a one-jointed decurrent gland, linear 
with the flat side perpendicular, about an inch long, one- 
nerved, slantedly pointed, with a small prickle at the end 
of the lowermost edge. Stipules minute, subulate, upright, 
caducous. Flowerheads yellow, axillary, peduncled, ge- 
nerally in pairs though often solitary, the size of a small 
pea, disposed bunchwise round the upper part of the 
branches. Peduncles about even with the leaf, filiform,
