618 DR. M. T. MASTERS : GENERAL VIEW 
The cotyledons, 8-8 in number, are triangular in section with 
subepidermal resin-canals and a central cylindric stele surrounded 
by endoderm, and having an unbranched fibro-vascular bundle. 
The primordial leaves are elliptic in section, with convex sides, 
subepidermal resin-canals, and a branched fibro-vascular bundle. 
The section of the adult leaf is boat-shaped, flattish on the 
ventral surface, with marginal canals, an elliptic meristele, as 
seen in section, and branched fibro-vascular bundle with a 
mass of stereome-cells between its two divisions. The endo- 
derm-cells are about 60. The anther-crest is short, rounded or 
retuse. ; 
The cones are usually stipitate and deflexed in the young 
state, spreading more or less horizontally in the adult condition. 
It is, however, not uncommon to find the adult cones erect. I 
have seen wild trees showing this character near Zermatt, in 
Switzerland, and in a cultivated state at Bournemouth and other 
British localities. 
The apophysis is sometimes raised and pyramidal, with 4-5 
sides, but in others it is flattish and lancet-shaped on the upper 
border. In another form the apophysis is decidedly hooked, as 
in P. montana var. uncinata. 
To Mr. Burbidge I am indebted for specimens showing the 
fascicles of leaves arranged in whorls separated by long inter- 
nodes (see fig. 5, p. 617). The disposition of otherwise isolated 
leaves in whorls is not uncommon, and is normal in Sciadopitys ; 
but an arrangement of several tufts of leaves in verticils has 
not, so far as J know, been previously noted. In fig. 3, p. 615, 
is shown another abnormal condition of the buds placed in the 
position of the male flowers, but consisting of perular scales 
only ; and in fig. 4, p- 616, are shown similar buds between the 
leaves at the apex of the contracted shoots.

This belongs to the silvestris group, but differs in the shape 
of the cone and of the apophysis. In appearance it is also like 
P. densiflora, but the cushion-shaped apophysis is prolonged into 
a central lobe and the umbo is deeply depressed. 
The semiterete leaves have a double layerof hypoderm, marginal 
resin-canals surrounded by stereome-cells, an oblong meristele 
(in section), and a divided fibro-vascular bundle.
