Specific Character .—Pinus foliis quinis; singulis trigonis filiformibus, sat rigidis, dorso sine stomatum 
seriebus ad facies laterales stomatum seriebus tribus vel quatuor instructis, vaginis caducissimis; strobilis 
elongatis et acute conicis cylindratis laete castaneis, squamis obtuse pyramidatis, apophysi dimidiato con- 
vexo corrugato opaco, umbone terminali acuto; seminibus parvis, alis brunneo-striatis. 
Habitat in California et Oregon passim. 
A handsome tree, reaching from 60 to 80 feet in height. Bark fuscous, splitting into square plates; 
young bark, greenish-brown, puberulous. Shoots destitute of leaves at the base. Branches, numerous 
and close. Leaves (fig. i) in fives, glaucous green, usually shorter and more rigid than in P. Strobus, 
about 3 inches in length, sometimes longer (fig. 2), rigid, trigonal, with an acute prominent keel, with 
the margins of the sides serrulated, but with the margin of the keel entire; the back flat, and without 
stomata (fig. 3), each of the inner sides usually with three or four rows of small whitish stomata (fig. 4). 
According to Engelmann there is a layer of woody fibres or hypoderm beneath the epidermis (absent in 
the nearly allied P. Strobus), and

so that in general none are to be seen, except when they are young and newly developed ; when adherent, 
it consists of two sizes of scales, the smaller ones at the base consisting of four or five ovate acuminate 
scales, the others of three or four long transparent scales, becoming ribbon-shaped when worn (fig. 5). 
Buds small, sharply acuminate (fig. 6). Male catkins small (about 1 inch long), pale, clustered around the 
stalk, surrounded with broad, bright, fawn-coloured scales. Anthers pale, bilocular, the rounded crest 
laciniate, ending usually in two projecting points, short, white. Female catkins purple. Cones pale when 
young,
