6 scales; crest of the anthers rounded; pistillate aments subterminal, their 
scales with erect or spreading points; cones oval, usually very oblique, and 
often curved, reflexed, 14-2’ long; scales, especially the lower ones, with 
largely developed pyramidal knobs in the centre, much smaller on the inner 
side, armed with strong or sometimes slender, awnlike prickles; seeds 
black, rough, ridged on the lower side; wing widest below the middle ; 
cotyledons usually 5. 
Southern Colorado to California, apparently not noticed in Arizona. 
A valuable timber tree of the northern mountain regions, forming large 
forests in the higher altitudes of the Rocky and California mountains, 
reaching into the British Possessions. The original form, discovered by 
Douglas near the mouth of the Columbia River (P. Bolanderi, Parlat.), is a 
seaside tree, extending up and down the coast, resisting the ocean storms, 
as does P. Halepensis those of the Mediterranean, and protecting the inside 
vegetation; it is distinguished by its low, scrubby, and often shrubby 
growth (whence probably the name), and its slender leaves, not more than 
4-2” wide; northward, in British Columbia and Alaska, both forms com- 
pletely run together. The species was formerly confounded with the East- 
ern P. inops, which differs by its lateral, more or less pedunculated cones ; 
it is more closely allied with the Northern P. Banksiana, which, however, 
bears its scarcely prickly or entirely unarmed, mostly lateral, rarely sub- 
terminal, cones erect or patulous, never recurved: a very unusual occurrence 
among pines. The cones of the Rocky Mountain form, and also those of 
the seaside scrub, are usually persistent for many years, and often remain 
closed after maturity (serotinous), while in the variety of the Sierras they 
appear to open on maturity, and to drop before the following season, as 
Prof. C. S. Sargent observed. 
Junreerus Vireriana, Linn.; Engelm. American Junip. in Trans. Ac. 
St. Louis, 3, 591—Santa Fé, N. Mex., Rothrock, in 1874 (43). Readily 
distinguished by its slender branchlets and leaves with entire margins. 
JuniPeRvs occIDENTALIS, Hook., var. MoNOsPERMA, Engelm. Junip.590.— 
A small tree or a bush, with fibrous bark, squarrose branches, and obtuse, 
minutely denticulate leaves in twos and threes; berries globose, blue-black,
