sessile, sharp-pointed, oblique at the base, oblong-conical, 1.5-3 em. 
(34-11% inches) long, erect, incurved or pointing in the direction 
of the branch. 
Distribution. Nova Scotia to the northwest territory, south to 
Maine, northern New York, southern shores of the Great Lakes to 
ce tral Minnesota. In Indiana it is frequent to common on the 
sand dunes bordering Lake Michigan. 
The published records of the dstribution are as follows: Lake 
(Hill) and (Blatchley); Porter (Blatchley); Putnam (MacDougal)*. 
Additional records are: Lake and Porter (Deam). 
Economic uses. In our area it is only a scrubby or medium 
sized tree and occurs so sparingly as to be of little economic im- - 
portance. 
3. Pinus virginiana Miller. Scrus Prinz. Spruce Pins. Plate 
9. Bark dark brown, with rather shallow fissures, the ridges 
broken, somewhat scaly; branches spreading, at first green, light 
brown or purplish with a bloom, becoming a gray brown; leaves in 
bundles of 2, rarely 3, twisted, deciduous during the third or fourth 
year, about 5 cm. (2 inches) long; cones sessile or nearly so, narrowly 
conic when closed, 4-7 em. (114-234 inches) long, opening in the 
autumn of the second year, frequently remaining on the branches 
3 or 4 years; scales armed with a curved spine 2-4 mm. (about 1-8 
inch) long. 
Distribution. From Long Island, New York, south along the 
coast to northern Georgia and Alabama, west to eastern Kentucky 
and southern Indiana. In Indiana it is confined to the ‘‘knob” 
region of a few counties near the Ohio River. As nearly as could be 
ascertained the limits of its distribution are as follows: North as 
far as Scottsburg in Scott County, west in Washington and Floyd 
counties to Blue River and east to the Pennsylvania railroad 
which passes through Clark County. In Clark County near Henry- 
ville it is found a few miles east of the railroad. This location is 
not contained in the “knobs” and it is believed that the few trees 
found obtained a foothold after the original forest had been cut. 
Investigation showed that it never occurred in any of the south- 
eastern counties. References to Pinus echinata should be referred 
to this species. Baird and Taylor reported Pinus rigida for Clark 
County but did not report virginiana which is common on some of 
the hills. Doubtless the preceding record of rigida should be re- 
ferred to virginiana. 
*Tbe specimen on which this record is made is in the Depauw herbarium, and is 7’suga canadensis,
