Wide tracts of sandy moorland in the south of England have been in the last century extensively planted with various species of Pinus, and afford the naturalist an interesting opportunity for comparing one with another. At Bournemouth the plantations are chiefly of the Austrian variety of Pinus Laricio,[15] the Scots P. sylvestris, and the Mediterranean Pinaster. The latter is especially luxuriant there. Here and there I have found other species at Bournemouth. A remarkable one with three needles in a group is the Californian Pinus insignis (Fig. 40), known as the Monterey pine. It has a very large cone which is curiously one-sided in growth, the seed-scales on the side facing away from the supporting branch being larger than those on the opposite face. Another interesting species to be met with there is the Pinus muricata, also a Californian sea-coast species. The cones of this species are about 3 inches long and half that in breadth. In all the species of Pinus the outer end of the scales which build up the cone is swollen and squeezed compactly by its fellows, forming a hard shield-like surface of a lozenge shape, in the middle of which is a knob or process (see Figs. 31, 39, and 40). Usually this is short and not very sharp, but in Pinus muricata the cone is very hard and solid and the knob is elongated into a spine of nearly one-third of an inch long (Fig. 41). Theses pines are so hard and sharp that they render it impossible to grasp the cone with the hand in order to pluck it. The cones remain on the tree for fifteen years or more, and may be seen in close-set clusters surrounding quite old branches. The cones of Pinus rigida--one of the American pitch-pines--are similarly protected by spines. Pinus rigida is easily distinguished by its having its needles in bundles of three from Pinus muricata, which has the more usual arrangement of a pair of needles to each bundle. The Douglas fir is also to be found here and there in the gardens and parks of Bournemouth. Its cones (Fig. 42) are remarkable for their beautiful purple and pale green tints when young, and for the long trifid bract on the outside of each scale, similar to but larger than those on the cone-scales of the silver fir, Abies pectinata (Fig. 35), and not bent backwards as they are. [15] A fine specimen is growing near the main entrance of Kew Gardens.

Compare these with the un-armed bosses in the centre of each lozenge building up the surface of the cones drawn in Figs. 31, 39, and 40.] [Illustration: FIG. 42.--Female Cone of the Douglas Fir of North-West America (Oregon and Vancouver), Pseudotsuga Douglasii.
