332 CONIFERZ OF DR. PARRY’S COLLECTION. 
pale, or dark green, — usually only 4-6, but also 10-15 lines long ; the fruit, however, differs in its position from that 
of all other Picez known to me, being borne on short, recurved, scaly peduncles ; it is 10-20 lines long, oval, acutish ; 
scales thick at base, very thin at the crenulate edges. P. alba is also best characterized by the slender cylindric cones, 
1-3 inches long, with thin scales, entire but not thickened, as I inadvertently stated in Sill. Jour. 1.c. The true char- 
acters and the limits of variation of these species are now being investigated by Prof. O. Brunet of Quebec, who, living 
in the midst of them, will be able to solve many doubts heretofore existing, and to give us their correct history. — Male 
aments of P, Engelmanni 6-9 lines long, on short stipes ; anthers 14 lines long; female aments 9-10 lines long, with 
ovate lanceolate scales almost equalling in length the dark purple, fleshy scales. Cones scattered on the tree, never 
very abundant, 1$-2} (usually less than 2) inches long, ? inch or less in diameter when closed; light yellowish brown 
Ww sas the lower part of the scales dark when fresh, all ead biaeei when old ; scales 6 lines wide, and 6-8 lines long 
well grown specimens, rhombic with truncated end ; in poorer ones, such as grow in lower elevations, shorter, more 
aiiasd with the truncation indistinct. I observe the same difference in cones of P. excelsa, grown on bushy trees 
near their upper limit in Switzerland ; there also cones, scales, and seeds are smaller, and the truncation of the scales is 
almost imperceptible. Seeds about 1 line long without, and 4} lines long with the wing, which here, as in all 
—— overlaps the inner edge of the seed, dropping it at maturity ; cotyledons, as in most species, 6, rarely [214] 
5; in P. excelsa J find 8, or rarely 9 (not 2-3, as Endlicher inadvertently stated), ae in the alpine specimens, 
ae above, only 6 cotyledons. 
a Menziesii, the only other species of Colorado, is entirely subalpine, occurring between the limits of 7,000 and 
9,000 feet j in low, moist, or marshy soil, especially on the borders of streams; it is, as Dr. Parry informs me, a tree of a 
more oval outline, pointed upwards, with a more rapidly tapering trunk ; thicker (4 inch), grayish, moderately rough 
bark ; rapidly-growing (annual rings 14-2 lines on an average), harsh-grained, brittle, knotty, resinous wood u 
light colored, smooth, glossy branchlets; stout, broad, sharply-pointed leaves; longer (9-12 lines) male and female 
aments, the latter composed of pale, glistening, orbicular scales, which are many times longer than the minute bract ; 
cylindric cones (3-4$ inches long, drooping perpendicularly with the branch or usually at an angle with it, sient 
even on young (12-15 feet igh’ trees, crowded especially towards the top of the tree and very conspicuous, whitish at 
maturity, but turning light brown and persisting on the tree for another year until the new crop matures; scales elon- 
gated rhombic, 9-11 lines long, truncate, more than twice as long as the seed with its triangular obovate wing. The 
alpine P. Williamsonti, Newb., from the Cascade Mountains, Oregon, which I have not been able to compare, seems to 
be well distinguished by its peculiarly reflexed scales. 
II. CONIFERZ OF DR. PARRY’S COLLECTION IN THE ROCKY MOUNTAINS. 
(BY DRS. PARRY AND ENGELMANN.) 
From Amer. Journ. Sci. AND ARTS, SECOND SERIES, VoL. XXXIV, Nov. 1862. 
Dr. Parry collected too few specimens of the following Conifers for distribution, but as [330] 
his notes are replete with interest they are given here (under marks of quotation) together 
with a few remarks of my own. 
ABIES GRANDIS, Lindl. Not common in this region, resembling much the Eastern A. balsamea. Fendler’s N. 
Mex. No. 828 is the same. 
Apres Dovetast, Lindl. “ Abundant through the eastern mountain district, except on the higher elevations. 
A very sightly tree, of the average height of 80 feet, with a graceful oval outline ; the spreading branches curving 
upwards at the extremities. Wood of slow growth, but very indifferent, inclined to warp and crack, turning reddish- 
brown in drying.” This species, as well as the nearly allied A. Canadensis, is well distinguished from all our other 
Pines by the distinctly petioled leaves, Fendler’s N. Mex. No. 829. 
Apizs Meyziesit, Lindl. “A finely shaped tree, though of rather stiff = of rapid growth ; very 
compact, but rather coarse-grained and pitchy ; the logs taper too rapidly to saw up to advantage.” Cones pendulous 
from the end of the branches. Leaves stouter than in any other allied species, stiff and tie acute, almost spinescent. 
Apres nigra, Poir. Probably the same as the northeastern tree (characterized by the slender and very acute 
leaves, ovate cones with thin and crenate margin of the scales), a pale-leaved form of which is usually named A. alba, 
but which Prof. ——— —— to A. nigra. The true A. alba (leaves somewhat stouter and obtusish,
