tiful tree, not excelled by any in California for its timber. A sweet substance, intermediate be- 
tween resin and sugar, exudes from it when wounded and partially burned, so that it is gene- 
rally known in California by the name of Sugar Pine. 
Pinus Eneetmannt. P. pracuyprera, Engelm. in Wisliz. Rep. p. 89. Hill-sides, Soni, Cali- 
fornia. Dr. Bigelow states that this vedinble pine makes its first appearance in the mountains 
between the Pecos and the Rio Grande, and occurs in large quantities on the mountain ranges 
- quite to the Sierra Nevada. See his report. It is called Yellow Pine and Pitch Pine in some 
parts of New Mexico.’ We have changed the specific name, because the wing of the seed -is 
not short; Dr. Engelmann himself having ascertained that the specimens from which his 
description“ was drawn were not perfect. In our plant the wing is nearly an inch long. The 
leaves are sometimes nearly six inches in length.

Mountain White Pine. ‘The onitniey height of the tree is from 40-50 feet, but Dr. Bigelow saw 
trunks of it that were more than 100 feet high. The seeds are edible tks those of P. Cembra, 
which this species greatly resembles. 
Pinus instants, Dougl. in Loud. Arb. 4, p. 2265, ¢. 2170-2172. Mountains near Oakland ; 
also on the south Yubaand on the Coast mountains, California. The cones, when fully grown, 
are about six inches long. They are usually gibbous and a little curved; the points of the 
scales much more developed on the gibbous side. The ordinary height of the tree is from 30-40 
feet. oh, may be the same as the imperfectly described P. Californica, Lois

very large, heavy cones, the scales of which are produced into a long stout incurved point. See 
Dr. Bigelow’s Report.
