Notes on trees and shrubs of the southeastern United States 
W. W. ASHE 
1. THE CASTANEA PUMILA GROUP 
Castanea pumila Margaretta var. nov. 
A tree, sometimes attaining (in Arkansas) a height of 15 m. 
and a diameter of 1 m., but usually smaller and often a large 
single-stemmed shrub. Leaves sinuate-serrate with ten to 
on the midrib and veins; shade leaves 5-12 cm , o-6-8 
oad, obovate or sometimes oblong-obovate, obtuse, or rounded 
and abruptly pointed at the apex, cuneate at t , thin, 
aaa 
with branched rigid canescent spines, 3-6 mm. long, which as a 
rule are not sufficiently dense to conceal completely the involucre. 
—-I15 mm. long, 7-12 mm. thick, pointed 
at the tip, shining, blackish brown. 
Dry soils or, at the upper edge of the longleaf pine lands of 
Texas and Louisiana, along the edges of sandy hummocks. 
The following collections have been made by the writer: ALA- 
BAMA, Winston County; Mussissrppi, Jackson; LoursIANA, 
Natchitoches and Sabine (Tyre) Parishes; TExAs, Sabine County; 
OKLAHOMA, McCurtain County; and ARKANSAS, common on the 
mountains. Named for Margaret Henry Newland. 
This variety largely replaces the typical C. pumila-(L.) Mill. 
west and southwest of Tennessee and is separated from it by hav- 
ing the much shorter and smaller shade leaves of an obovate 
outline, thinner and often green beneath ; by the closer white pube- 
scence on the narrow and acute sun leaves (never velvety and 
rarely dull grayish); by the spines of the involucre being 
canescent well toward their tips (those of the typical C. pumila 
being nearly glabrous when mature) and seldom so dense as to 
conceal the involucre. Nut apparently not quite so plump as 
that of the type.
