374 PINUS ELLIOTTII. 
43. P. Elliottii, Engelm. For a full account see below. 
44. P. Cubensis, Griseb. Leaves in threes, only exceptionally in twos, 8-10 inches long, rarely longer, stout, 
about ? line wide, rigid, strengthening cells largely developed under the epidermis (so that their bundles sometimes 
extend from the epidermis to the ducts) and also near the vessels ; bracts 3-34 lines long, strongly fringed, reflexed, 
rather persistent ; male flowers about 14 inches long; involucral bracts 13-15, the outer pair half as long as the inner 
es ; anther-crests scarcely denticulate ; cones 24-3 diichins long, short-peduncled, scales depressed ; seeds 3} lines long, 
faintly ridged ; wing nearly twice as ‘ea, widest at base, tapering to an acutish point. The var. terthocarpa, Wright, 
in Gris, Cat. Cub. 217, is a very curious ‘form but not a variety. It seems that in this case the growth of the axis is 
entirely arrested after producing an ament, and does not even elongate in the following season ; the maturing cone, 
therefore, remains erect near the top of the branch. I have seen an analogous arrest of growth in the biennially- 
maturing Quercus chrysolepis. It is found in different parts of Cuba, in the maritime districts as well as on the moun- 
tains, sri i is probably the same that gives the name to the Isle of Pines. A cone from the Bahama Islands, preserved 
in the Kew Museum under the name of P. Teda, probably also belongs here. 
45. P. Wrightii, Engelm. n.sp. Leaves in twos, very rarely in threes, slender, 5 to 8 inches long, $ line or less 
wide ; sheaths 4 lines long, with age a little shorter ; bracts small (14 lines long), very slightly fringed and rather 
deciduous ; cones lateral, peduncled, recurved, oval, 14 to 2} inches long, scales radiately grooved, thickened on the 
crenulated edge, apophyses retused, umbo immersed, prickles short ; seeds 2} lines long, faintly ne wings (perhaps 
incomplete ?) not much longer, widest above the base. — Mountains in Eastern Cuba, apparently mixed with the last, 
Chs. Wright, No. 1462 in part, 3190. Distinguished from the allied P. Cubensis by its slender binate leaves, short 
scarcely fringed deciduous bracts and smaller cones and seeds. I have not seen the male flowers. The cone-scales of 
both species are arranged in the $} order, the 8 and 13 spirals being the most prominent. 
PINUS ELLIOTTII, Encetm. n. sp. 
A LARGE tree, 50-100, rarely to 110 feet high, 2-4 feet in diameter, with (7-15 lines [186] 
thick) laminated, reddish-brown bark ; leaves in twos and threes, in the axils of lanceolate, 
long-fringed, somewhat persistent bracts, 7 to 12 (mostly about 9) inches long, } to nearly 1 line 
wide, rigid, closely serrulate, acutish ; sheaths at first about 2 inch long, later waltcnies to one-half 
that length ; resin-ducts internal facitnecat to the sheath of the vasonli bundles). Male flowers 
from the axils of similar, persistent bracts, cylindrical, elongated (14 to 2 inches long), in a short 
head (not more than 1 inch long), each one surrounded by an involucre, 4 lines in length, of about 
12 bracts, the exterior pair strongly keeled, half the length of the inner ones; anthers with semicir- 
cular, denticulate, rose-purple crests ; pollen grains 0.037 to 0.045, on an average 0.04 lines in the 
longer diameter. Female aments peduncled, mostly 2 to 4, or rarely to 6 together, oval, purplish, at 
first erect, but soon assuming a horizontal and (a month later, and before the leaves are well devel- 
oped) a recurved position, the axis meanwhile elongating and in vigorous trees not rarely forming a 
second tier of aments several inches above the first ones; the bracts above the aments bear the usual 
leaf-bundles, so that no naked space is left; carpellary scales broad, rounded, more or less abruptly 
cuspidate, their bracts half their length, transverse, retuse. Cones peduncled, recurved, oval to 
cylindrico-conical, 3 to 64, usually 4 to 5 inches long, 1? to 2} inches in diameter (when closed), of 
arich brown color and sieioes glossy ; bracts thickened, retuse, or emarginate ; scales in }? order, 
the 5 and 8 spirals most conspicuous ; larger scales 2 inches long and 7 lines wide ; ade marked 
with grooves, radiating from the slightly prominent umbo, icinkvenssly divided by a sharp ridge, 
armed with a short stout or rarely a slender sharp prickle. Seeds triangular, 2} to 3} lines long, 
dark, slightly ridged, and rough on the under side; wing 4 or 5 times as long (13 to 16 lines long), 
somewhat oblique, obtuse, with nearly parallel sides, or usually somewhat broader below, its base 
covering the greater part of the outer or upper surface of the seed; cotyledons 6 to 9, usually 8.—

the marshes near the mouths of rivers; ales tonud in damp clayey pine lands and with [187]
