a_, Barrett.--A handsome tree at Fort Kent, 25-30 feet
high, with trunk 4-6 inches in diameter. (M. L. Fernald _in lit._,
September, 1901.)

_Crataegus Crus-Galli_, L.--Nantucket, Massachusetts. Young trees were
set out in 1830, enclosing an oblong of about an acre and a half. The
most flourishing of these have obtained a height of about 30 feet and a
trunk diameter near the ground of 10-12 inches. Now established,
probably through the agency of birds, along swamps and upon
hill-slopes. (L. L. D.)

_Prunus Americana_, Marsh.--One clump of small trees in a thicket at
Alstead Centre, N. H., has the characteristic spherical fruit of this
species. _P. nigra_, Ait., with oblong, laterally flattened fruit, is
abundant. (_Rhodora_, III, 234.)

_Acer Saccharum_, Marsh., var. _barbatum_, Trelease.--Characteristic
trees (Cheshire County, N. H.), with small, firm, deep green,
three-lobed leaves, appear very distinct, but many transitions are noted
between this and the typical _Acer Saccharum_. (_Rhodora_, III, 234.)

_Acer Saccharum_, Marsh., var. _nigrum_, Britton.--Occasional in
alluvium of the Cold river (Cheshire county, N. H.). The large, dark
green, "flabby" leaves, with closed sinuses and with densely pubescent
petioles and lower surfaces, quickly distinguish this tree from the
ordinary forms of the sugar maple. (_Rhodora_, III. 234.)

_Fraxinus Pennsylvanica_. Marsh., var. _lanceolata_, Sarg.--Common along
the Connecticut at Walpole, N. H. (M. L. Fernald _in lit._, September,
1901.)
