abundance of fruit. Mr. Gunn describes it as growing at Lake 
St. Clair to the height of 25-30 feet, with trunks 18 inches to 2 
feet in diameter; one very old one, hollow in the centre, measured 
15 feet round, at 3| feet from the ground, from whence it tapered 
rapidly upwards.

Hab. Tasmania, Falls of the Meander River, Gunn (n. 369). 
Some doubt was expressed in the “ leones Plantarum” of the 
validity of this species, neither the flowers nor fruit being known. 
Another specimen, with cones, received from Mr. Gunn, seems to 
establish its claims to specific distinction. The cones are nearly 
the size of those of A. selaginoides, with the seeds smaller and of 
a different form, being (including the wings) broadly oblong, their 
sides parallel, and the base and apex emarginate; the wings are 
thick, and formed of two membranes inclosing a spongy sub¬ 
stance, as in A. cupressoides, but they are broader above than in 
that plant; the embryo is altogether like that of the two former. 
The leaves are as represented in the “ leones Plantarum,” in 
fewer series, shorter, smaller, and more lax than in A. selagi¬ 
noides.
