magnified section, in which the hypoderm, the resin canal, and the bundle of fibres are all shewn, Mmle 
catkins (fig. 6) erect, conico-ovate, somewhat teasle-shaped, growing in clusters ; pedunculate, terminal, 
yellowish fawn colour, with numerous long 
recurved stamens. Their position is 
shewn in the section, fig. 7. Anthers 
(fig. 8 natural size and fig. 9 slightly mag¬ 
nified), two celled at the base, terminating 
in a leaf-like scale. Cones (see plate) solitary at the end of the branches, erect, very 
large, dark brown, nearly sphaeroidal, somewhat depressed, of from 6 to 8 inches in 
diameter. When fully ripe they fall very easily to pieces. 
Scales and bracts (figs. 10, 11, and 12) amalgamated with the seeds, somewhat an¬ 
gular, narrowest at the base, more than an inch in length, forming a thick shell 
surrounding an edible kernel; without wings; the short lobe, 
which may be mistaken for a wing, corresponding not to the 
wing, but to the apex of the scale, and the prominent scale¬ 
like apophysis being in truth the bract, and not the scale. The 
seed (fig. 13) is long and wedge-shaped. Fig. 14 shews it 
split open. In the mature state it is solitary, and, as already 
said, its shell absorbs, or is conjoined with, the whole of its 
usual appendages—the wing, the scale, and the bract. But 
although the seed thus appears single, it is not so theoretically,

or always. 
Both Molina and Pavon, who first described the species, say that each scale has two ovaries; 
and Lambert, in his description of the species, gives a figure, furnished to him by Pavon, in 
which the presence of the two seeds in the young state is distinctly visible (fig. 15). In the specimens 
which reach this country, the seeds are 
all solitary; but this is due to their 
being all mature. We have, through 
the kindness of Mr Barnes, the gar¬ 
dener at Lady Rolle’s, Bicton, had the 
opportunity of examining the young 
cones from specimens taken from trees 
orowinor at Bicton, and we find that 
00 7 
they are exactly as figured by Pavon 
in Lambert’s plate. Almost every part of the tree abounds in 
a milky-white resin. 
According to Pavon, the male tree, in its native country, 
grows only to 30 or 40 feet high, while the female reaches 150 feet in height. He 
gives the following account of it in a description published in the Memoirs of the 
Royal Academy of Sciences at Madrid :—“ Its trunk is quite 
straight, and without knots, ending in a pyramid formed of hori¬ 
zontal branches, which decrease in length gradually towards the 
top, and is covered with a double bark; the inner is 5 or 6 
inches thick, fungous, tenacious, porous, and light, from which,

outer is of nearly equal thickness, resembling cork cleft in various 
directions, and equally resinous with the inner.”
