A NEW SPECIES OF ARAUCARIA. 503 
ARAUCARIA BipwinLi, Hook. ; 
Foliis patentibus ovatis pungenti-acuminatis demum bas 
insigniter dilatatis, amentis foemineis in ramulis propriis later- 
alibus brevibus erectis ovali-subglo bosis maximis, squamis 
laxis late alato dilatatis bi-labiatis labio inferiore seu apice 
acuminato reflexo, interiore acuto breviore. (Tab. X.) 
Has. Mount Brisbane range of hills, 70 miles, N. W. of 
Moreton Bay, Australia, J. T. Bidwill, Esq. 
A tree, according to Mr. Bidwill’s Notes, * growing from 
100 to 150 feet high, with a remarkably stout trunk, which 
scarcely tapers for one half of its height from the base, 
covered with a smoothish black bark. Dead branches com- 
mence at about half way, and continue nearly to the summit, 
where the living branches are seen produced about sixteen in 
a whorl, the largest of them not 14 inch in diameter, 12 
feet long; branchlets distichous 14 foot long; these living 
branches are densely crowded together, occupying in adult 
trees not 1-30th part of the whole height of the plant; (but 
this would not be the case, probably, if the tree grew in the 
open country); or, in other words, in the trees which I had 
the opportunity of examining, there are no live branches, 
except on those extremities which rise above the surrounding 
forest, and they form a very obtuse conical or almost hemi- 
spherical head.” (Bidwill) Leaves patent, sometimes al- 
most standing out at right angles, spirally arranged on all 
sides, ovate pungently acuminate, of a remarkably hard and 
firm texture, slightly coneave above, a little convex beneath 
and marked or impressed generally with two lines from the 
close application of the lower leaves in the infant state, dark 
green, glossy, when seen under a microscope beautifully 
marked with lines of minute pale dots :—their average length 
is rather more than 2 of an inch, but occasionally I have 
seen them, probably the effect of accident, 1 or 2 inches long 
on some of the young branches, oblong-lanceolate, and more 
or less secund. In the younger and terminal branches the 
leaves are rather crowded, yet even there a singular dilation 
of the base may be observed, especially at the upper and under
