by its smaller flowers with 10 not 20 stamens, smaller and less 
tomentose leaves, and by its smaller oblong or pear-shaped fruits, 
which usually do not fall until winter. 
C. Pringlei. Leaves oval, pointed, rounded and often abruptly 
contracted at the base into the slender petioles, or on vigorous shoots 
truncate or slightly cordate at the base, sometimes irregularly lobed 
with short broad acute lobes, coarsely and often doubly serrate with 
gland-tipped teeth, at the flowering time roughened above with short 
closely appressed pale hairs, glabrous below with the exception of a 
few pale hairs along the slender midribs and remote primary veins, 
at maturity thin, glabrous and bright yellow-green on the upper sur- 
face, paler on the lower surface, from 2 to 24 in. long and from 13 
to 24 in. wide, or on vigorous shoots often 3 in. long and wide; peti- 
oles from 1 to 1$ in. long, deeply grooved, at first villose or tomen- 
tose, more or less glandular with scattered dark glands, finally often 
nearly glabrous. Flowers from $ to 1 in. diameter, in many-flowered 
tomentose corymbs; calyx broad, tomentose, the lobes lanceolate, 
coarsely glandular-serrate, hirsute on the upper surface; stamens 
10; filaments slender; anthers small, yellow; styles 3 to 5, sur- 
rounded at the base by conspicuous tufts of pale tomentum. ' Fruit 
oblong, dark dull red, villose at the ends with long scattered pale 
hairs, marked by a few large pale lenticels, 3 in. long, about $ in. 
thick; calyx cavity deep and narrow, the lobes nearly triangular, 
tomentose, pale, erect, often deciduous ; flesh yellow, thick, dry and 
mealy, acid, with a disagreeable flavor; nutlets 5, pale, } in. long, 
rounded and slightly ridged on the back. 
A tree from 20 to 25 feet in height with a well-formed trunk cov- 
ered with dark red-brown scaly bark, stout branches forming a wide 
symmetrical head, or often of shrubby habit with numerous erect 
stems, and slightly zigzag branchlets marked with oblong pale lenti- 
cels, at first dark green and tomentose, becoming chestnut-brown and 
very lustrous during their first season, bright orange-brown during 
their second year and ashy gray during their third season, and armed 
with stout straight or slightly curved chestnut-brown spines often 14 
in. long. Flowers open during the last week of May. Fruit ripens 
at the end of September or early in October and soon falls. 
Common in the Champlain Valley at least as far north as Char- 
lotte, Vermont, where it appears to have been first collected in May,
