Where there is space for the display, a good collection of 
New Holland Acacias exhibits some of the most interesting 
among Green-house plants. The strange variety in the phyllodia 
(or leaves as they are generally called), the profusion and fra- 
grance of their blossoms, and the season of the year when they 
are in the greatest perfection, render them eminently worthy of 
cultivation. The Swan River Settlement, investigated by the 
industry and discrimination of a Drummond, has contributed to 
the stores already in our possession from the older parts of our 
Australian Colonies; and many of the species are eminently 
worthy of a place in our Magazine. Acacia leptoneura recom- 
mends itself by its graceful slender branches, loaded with 
deep orange-yellow heads of flowers, rather than by any striking 
character in the foliage (phyllodia); except when this latter is 
magnified, (as shown in a transverse section, f.3,) and then the 
circle of air-cells, one beneath each ridge or nerve of the leaf, 
becomes visible, resembling, in that respect, as well as in the 
roughness of the superficies of the leaf itself, the joint of an Zgui- 
setum. The present species flowers in April. 
Descr. A shrub, five or six feet high, with very straggling 
branches, which are terete and wavy. Phyllodia alternate, two 
to three inches long, spreading, flexuose, subulate, or rather 
filiform, with an acuminate, sharp, terete, hooked point, minutely 
and copiously nerved or striated, rough on the surface when
