MONOECIA MONADELPHIA,

1. Inops. Aiton. 
P. foliis brevibus ge- 
minis; strobilis recur- 
vis, oblongo-conicis, 
longitudine foliorum, a- 
culeis sqnamarum subu~ 
latis, rectis. 
Leaves short by 
pairs; cones recurved, 
oblong, as long as the 
leaves, spines of the 
scales subulate, 
straight. 
Sp. pi. 4. p. 496. Mich. 2. p. 204. Pursh 2. p. 640. Nutt. 2. p. 223. 
P. Squarrosa? Walt. p. 237? 
Icon. Mich. arb. for. i. p. 58. 
A small tree, rarely attaining the height of 30 or 40 feet, and 12 — 15 
inches in diameter, with scattered, tough, flexible and smooth branches. 
Leaves , as in all of the genus linear, acute, 1 — 2 inches long, united in pairs 
in each seath. Cone ovate, about 2 inches long; spines near the summit 
of the scales subulate, straight, acute. 
This is a scrubby species of pine, and its wood is said to be of little value. 
It is said by Pursh to grow in Carolina; and it is probably one of the 2-leav- 
ed species described by Walter. I have, however, never seen it in the low 
country of Carolina or Georgia. 
Grows in dry gravelly soils.

2. Variabilis. 
P. foliis elongatis 
binis ternatisque ten- 
uibus, canaliculatis; 
strobilis ovato-conicis 
subsoiitariis; squama- 
rum aculeis incurvis. 
Leaves by pairs and 
by threes, slender, 
channelled; cones ge- 
nerally solitary; spines 
of the scales incurved. 
Sp. pi. 4. p. 498. Pursh, 2. p. 643. Nutt. 2. p. 223. 
P. Mitis, Mich. 2. p. 204. 
P. Glabra? Walt. p. 237* 
Icon. P. Mitis, Mich. arb. for. p. 52. 
A large tree, sometimes growing 70 — 80 feet in height, and 2 — 3 feet in 
diameter, more disposed to branch near the surface of the ground than is 
common in this genus, and it therefore is only in very thick woods that it is 
found with a straight naked stem. Leaves generally 2 in each sheath, 
(sometimes 3 on young branches, Mich.) 4—5 inches long, of a darker green 
than those of our other pines. Cones small, solitary, not exceeding2 — 3 
inches in length.
