138 So»ze Notes on the Conifercs of California. 



and with a tall trunk free from branches to the height of thirty or forty feet 

 {Fineium, p. 205). Its long, twisted, rather broad and flexible, sharp pointed 

 Jeaves, thickly set on the branches, and straight, ovate cones, must rendei 

 it conspicuous either in the young or adult tree. 



6. P. Sabiniana (Douglass). — The digger-pine. This is one of the 

 species called in California the white pine, and remarkable, says Dr. Torrey, 

 for its veiy large, heavy cones, the scales of which are produced into a long, 

 mc\!iXVQ.Ci^(yml {Botany ill Pacific R. R. Survey, vol. iv. p. 141). The scales 

 of the cones. Dr. J. M. Bigelow tells us (in the above work, p. 25), are 

 armed with large upturned, hooked spurs. The nut is said to be large, and 

 fit to eat. This tree is flexible and crooked; the foliage thin, and of a light 

 green, giving it a very peculiar aspect. As to the value of its wood, there 

 are very contradictory assertions : some call it excellent, and others denounce 

 it as useless (Bolander). A figure of the leaves and of the singular cone 

 may be seen in Loudon's Arboretum, p. 2247 ; and, judging from his figure 

 of P. Coultcri (Don), it would be inferred that the two species were identi- 

 cal ; although the latter is said to be a stately tree, rising to the height of 

 eighty to a hundred feet. The difference may perhaps be, however, owing 

 to the particular situation in which they were found ; the soil influencing 

 greatly the growth of these forest-trees. 



7. P. tuberculata (Don). — Loudon speaks of this tree as of a hundred 

 feet in height of stem, with oblong cones, of threes in a cluster, of a tawny- 

 gray color, four inches long, two and a half broad, the scales wedge-shaped, 

 dilated at the apex, quadrangular, truncate with a depressed umbilicus, 

 larger at the external base, conical, with an elevated apex ; quoting from 

 Don in Linncean Transactions : while Mr. Bolander calls it a small tree, as 

 occurring in his Explorations, from twenty to thirty feet high, retaining its 

 lowest branches, and they spreading out horizontally {Proceedings, I. c.).i A 

 tree of slow growth, says Loudon, and seldom attains more than thirty feet 

 in height, with a trunk eight or ten inches in diameter ; found growing by 

 Mr. Jeffrey at an elevation of five thousand feet ; in several instances, with 

 the cones persistent, numbering as many as twenty whorls of cones, and thus 

 indicating the fruit of as many years {Pinctum, p. 213). 



8. Cupressus macrocarpa (Hartweg). — The Monterey cypress. This 

 fine and singular species was found by Mr. Hartweg in Upper California,
