BOTANY 
sought for in the neighborhood where it grows, the presumption is that it cannot bevery valu¬ 
able. This, however, is only a negative testimony against it, for it is surrounded and asso¬

Pinus. —An undetermined species. 
High up in the mountains east of Sonora, (almost in the snowy regions,) and also at Cajon 
Pass, a pine was discovered very nearly related to the yellow pine of this country, (P. bra- 
chyptera,) hut the cone is larger and more cylindric ; the scales armed with a strong recurved 
spine ; the leaves longer, regularly in threes, and with a longer sheath. A very good figure 
was made of this pine by our artist, Mollhausen. It is a large tree, with a lighter-colored bark 
than the P. brachyptera, and fully as valuable for its timber. I am not certain that it is a 
new species.
