Boissier, Fl. Orient. v. (1884) p. 608. 
This species, native to the mountains of Macedonia, Monte- 
negro, Servia, and Bulgaria, where it occurs scattered among 
Spruce Firs, was at first considered to be conspecific with the 
Himalayan P. ewcelsa. The evidence that they may have origi- 
nated from the same stock is strong, but the shorter leaves, 
shorter cone-stalks, thicker shorter cones, and sinuously-veined 
seed-wings of P. Peuke now suffice to distinguish it from 
P.excelsa. (See Masters, in Gard. Chron., Feb. 24, 1883, p- 244, 
f. 34.) 
The young shoots are glabrous, green, and destitute of leaves 
near the base. The primordial leaves are membranous, brown, 
lanceolate-acuminate. The adult leaves are aggregated into 
ascending, wedge-shaped tufts, whilst those of ewcelsa are usually 
decurved. The resin-canals are marginal, surrounded by stereome- 
cells, and have the same structure as in P. excelsa. The leaves 
are three-sided, with no stomata on the convex dorsum, and with 
a circular meristele (in section). The resinous buds are ovate- 
acuminate. The male flowers, hitherto undescribed, are arranged 
in clusters. Each is about 8-10 mill. long, 3 mill. broad, orange- 
yellow flushed with pink. Anthers shortly mucronate or muticous, 
devoid of the laciniate crest which characterizes the anthers of 
P. excelsa. The cones, which Grisebach describes as erect, are 
only so in the young state, when mature they are deflexed. 
The cone-scales are rounded, with a small blunt point, and the 
wing of the seed is longer than the seed itself and traversed with 
sinuous veins. Grisebach, probably by inadvertence, described 
the seeds as exalate. Cotyledons 9-10.

A tree, very variable in habit as seen in cultivation. The 
herbaceous shoots are glabrous, naked at the base, and the cone- 
scales are remarkably broad near the apex. It is described in 
almost all the text-books and is well figured in the ‘ Gardeners’ 
Chronicle,’ February 24, 1883. The seed-wing is twice the 
length of the seed itself. The leaves are three-sided with marginal 
resin-canals, meristele circular in section, and the fibro-vascular
