very distinct, parallel veins ; a more conspicuous one con- 
nects the gland with the central nerve. The colour isa 
yellow-green, but clothed with a slightly glaucous tint. 
The flowers are arranged in perfectly globular capituli, of 
a delicate yellow colour, and about the size of large peas, 
and these are racemose; the peduncles shorter than the 
leaves, terminal and axillary ; when axillary, they are either 
solitary or two together, with one shorter than the other, 
but both shorter than the leafstalks. Each has from four 
to six or eight heads of flowers. Calyx five-toothed, cup- 
shaped, and brown. Corolla quinquefid, pale yellow, as 
are the numerous stamens. 
Much difficulty attends the investigation of the leafless 
New Holland species of Acacta, or the tribe of Puytio- 
pINEE, as De Canpotte calls them; and we must proceed 
with caution in determining the species, which, from time 
to time, flower in our greenhouses. The present plant 
exists in the Botanic Gardens of Edinburgh and Glasgow, 
and may, probably, be common in other collections, having 
been received under the unpublished name of A. imnpressa. 
It is, however, unquestionably, the A. penninervis of S1s- 
BER : a name sufficiently appropriate, considering, that the 
species, with which it is liable, at first sight, to be con- 
founded, is the A. melanoxylon; but, which is, nevertheless, 
essentially distinguished by its many parallel nerves. It is, 
indeed, perhaps, still more nearly allied to A. faleata, which 
may likewise be called penninerved, but the racemes of 
me touch shorter, and the leafstalks are destitute of

_ We possess several other species which will come into the 
same natural group with the present, and are equally fur- 
nished with a gland on the margin of the leaf; some with 
two. In every instance there is an oblique nerve or vein, 
which connects it with the principal nerve.
