SELECT PLANTS. 
Panicum turgidum, Forskael. 
Egypt, where this millet yields a 'oread-grain. P. Irizanthum 
(Hoclist.) is a large-grained perennial millet from Abyssinia and 
Nepal. 
Panicum virgatum, Linno. 
North America, South Asia and North Australia. A tall perennial 
species, with a wide nutritious panicle. 
Papophorum commune, F. v. Mueller. 
Widely dispersed over the continent of Australia, also in some 
parts of Asia and Africa. Perennial ; regarded as a very fattening 
pasture-grass, and available for arid localities. 
Pinus contorta, Dougl. 
(P. Bolandri, Parlatore.) Also abundant on the mountains of 
Colorado, and very eligible for clothing rocky hill-sides (Meehan). 
In California it forms dense thickets along the coast, and is in this 
respect as valuable as P. Laricio, P. Pinaster and P. Halejppensis 
in Europe. 
Pinus Douglasii, Sabine. 
Called also the Yellow Pine of Puget-Sound, where it yields the 
principal timber for export, and is therefore of great commercial 
value in the lumber-trade. The maximum height known is 400 
feet, the greatest diameter of the stem 14 feet. The timber is fine 
and clear- grained, splendid for masts and spars, also for flooring, 
being for that purpose regarded as the best of California 
(Bolander). It is the strongest wood on the North Pacific coast, 
both in horizontal strain and perpendicular pressure. Sub-alpine 
localities here should be extensively planted with this famous 
tree. It requires deep and rich soil, but likes shelter ; its growth 
at the rate of the Larch, and passes in various localities as Black 
and Red Spruce. P. Lambertiana yields also much of the 
flooring- wood in California. 
Pinus edulis, Engelmann. 
The Nut Pine of New Mexico. Thrives best on dry limestone 
soil. Greatest height 80 feet. P. rigida is content with the 
driest localities, nor is it readily susceptible to injury from fire. 
Pinus flexilis, James. 
The "White Pine of the Rocky Mountains, from New Mexico to 
British Columbia, ascending to 12,000 feet. A valuable Fir for 
cold regions. It attains a height of 100 feet. Wood pale and 
compact. P. radiata can be utilized for obtaining tar and pitch. 
It bears exposure to the sea at the very edge of the coast.
