This is a peculiar plant, with much the habit of Pycnarrhena. 
The branch is 2 lines thick, with axils ^-1 inch apart; the leaves 
are inches long, 3-3j inches broad, with a narrow acu- 
minate apex 6-9 lines long and 2 lines broad, the petiole being 
1^ inch long : the peduncle is 3-4 lines long, the umbellated 
pedicels 2 lines long ; the flower before expansion ^ line in dia- 
meter. 
58. Selwynia. 
This genus was founded on an Australian plant by Dr. F. 
Mueller, who deseribed it in his ‘ Fragmenta,’ iv. 153. It is 
evidently a climber, with slender branches, furnished with 
shining, glabrous, lanceolate leaves, somewhat acute at both ex- 
tremities, 3-nerved as well as triplinerved at base, reticulated, 
and upon slender petioles. The ^ inflorescence is axillary, pani- 
culate, on a slender divaricated rachis half as long again as the
