102 Rhodora. [JUNE 
westernmost record is Clifton Forge [Tm. no. 36] where I observed 
it at the base of the mountain and to some extent on the slopes, while 
Pinus pungens crowned the ridges. Some miles westward at Coving- 
ton, I noticed no Pinus virginiana, but found Pinus Strobus Tm. 
3153] scattered, Pinus rigida |Tm. 3154], and Pinus pungens [Tm. 
3158] frequent. On the Eastern Shore, Pinus virginiana is frequent 
and sometimes abundant. I have observed it associated with Pinus 
Taeda near Cape Charles and in many localities northward. The 
densest stands, however, are not found on the Eastern Shore but in 
the western portion of the coastal plain and in the Piedmont region. 
It was first recorded by Plukenet in 1696 under the name Pinus 
virginiana binis brevioribus de crassioribus setis etc., and also by 
Clayton. In the stamping ground of that enthusiastic pioneer — at 
Gloucester Court House and adjacent region — I have found the scrub 
pine frequent, even forming forests here and there. 
Prxus EcuiNATA Mill. appears to be a rare tree in our region. I 
have collected specimens of it from a tree (introduced?) in the park 
of the U. S. Soldiers Home, Washington, D. C., and in St. Mary's 
County, Md., between Leonardtown and Millstone ['Tm. 5113]. In 
the latter region it was mixed with the prevalent Pinus virginiana. 
There is a single tree in a field one mile west of Warrenton, Virginia, 
from which I collected specimens this spring [Tm. 6239]. 
Pinus PUNGENS Lamb. This interesting little pine was first dis- 
covered by Michaux on Massanutten Mountain in Virginia. I had 
never seen the tree growing wild until August 2, 1907, when I botanized 
at Clifton Forge. At this place I found it scattered among several 
species of oaks, particularly Quercus alba and Quercus prinus monti- 
cola. Since that time I have found the tree in several localities — 
at Pen-Mar on Mount Quirark |Tm. 5889] at an elevation of 630 m.; 
on Sugar Loaf Mountain, Maryland, at an elevation of 360 m. At 
the latter place there is a number of trees on the very rocky and steep 
slopes besides those crowning the summit. The tree is also present 
at Thoroughfare Gap, Virginia. There are a few trees in Rock Creek 
Park, Washington, D. C., and also some along the rocky bluffs of the 
Potomac River, about 15 miles above Washington. The tree is pre- 
eminently an inhabitant of the high ridges and plateaux — hence its 
name Table Mountain Pine.
