In the branchlets the vertical lines (including the angles) are much more 
accentuated when the plant is dry, i.e., these sharp lines are accentuated by 
shrinking. 
There seems to be but little difference between the seedlings of the various 
species. 
Male amenta. —The number of male amenta seems to be of no specific 
value. Where Bentliam describes the male amenta he used the expression, “ Solitary 
or three together, or usually three together.” Usually there are more than one, but 
we have one commonly in the Tasmanian C. cupressiformis. 
Stailliniferous flowers. —In the Conferee the male flowers consist only of 
stamens, and have mostly the shape of a triangular scale excentrically stalked on 
the face. On the lower margin of the scale are the anthers or pollen-bags. They 
are always one-celled, roundish or elongated (linear in Araucaria) , and amongst 
themselves mostly little or not at all connected. 
The scale is structurally the filament; we see a small scar, which is the point 
of attachment to the plant, and the oval bodies at the base are the one-celled 
anthers, the “ anther-cells ” of Bentliam. These anthers lie in shallow depressions 
in the scale. Hook, f., in his Flora Tasmanice, calls the scale and its anthers a 
stamen, which indeed it is. According to Bentham, the Australian species have 
two to four anther-cells. He, however, never gives the number of anther-cells on 
the scale as a distinguishing character between the several species. 
Attention is drawn to the terminal scale in C. cupressiformis, which is drawn 
out to a point like an operculum. I have not seen attention drawn to it, although 
it can scarcely have escaped notice. 
Pistilliferous flowers. —See the drawings of the pistilliferous flowers of 
C. cupressiformis and of C. calcar at a. 
Fruits — 
Callitris of Ventenat * is peculiar to Terra Australis, where it exists very generally, but most 
abundantly in the principal parallel; it consists of several species, differing from each other chiefly in the 
form of their fruit. R.Br., Botany of Terra Australis (Flinder’s Voy.), p. 574 (1814). 
This is important as showing what Robert Brown (who described several 
species) chiefly relied upon. 
These fruits vary much in size; those of C. cupressiformis are the smallest, 
while those of C. verrucosa and C. propinqua are the largest. They usually persist 
on the branches for many years. C. robusta and C. cupressiformis, for example, 
appear to be an exception in this respect. In these species one can always find 
large numbers under the trees and on the young wood, but in some other species, 
e.g., verrucosa and propinqua, they are always on old wood.
