nate lateral lobes; more than half grown when the flowers open and 
then very thin, light yellow-green and roughened above by short rigid 
white hairs, pale and glabrous below with the exception of a few 
hairs along the base of the midribs; at maturity membranaceous, 
yellow-green, lustrous and scabrate on the upper surface, pale on 
the lower surface, 6-7.5 cm. long, 4—6 cm. wide, with slender midribs 
and 4 or 5 pairs of thin primary veins extending obliquely to the 
points of the lobes; petioles slender, grooved, mostly wing-margined 
to below the middle, sparingly glandular, with minute red deciduous 
glands, often rose-colored late in the season like the under side of 
the midribs, 1.2-1.6 cm. in length. Flowers r.8-2 cm. in diameter 
on long slender pedicels, in broad many-flowered thin-branched 
slightly villose compound corymbs ; bracts and bractlets acuminate, 
bright red, small, mostly deciduous before the flowers open; calyx- 
tube broadly obconic, glabrous, the lobes wide, acuminate, conspic- 
uously glandular-serrate, villose on the inner face, reflexed after 
anthesis; stamens 20; anthers pale rose-color; styles 3-5, usually 
3. Fruit on slender glabrous pedicels, in few-fruited spreading clus- 
ters, oblong, full and rounded at the ends, 1-1.1 cm. long, 9-10 mm. 
wide, crimson, lustrous, marked by few large pale dots; calyx prom- 
inent with a broad deep cavity and spreading closely appressed 
coarsely glandular-serrate lobes, villose and bright red at the base on 
the upper side; flesh yellow, thick and succulent; nutlets usually 3, 
about 7 mm. in length, rounded at the ends, broad, ridged, the ven- 
tral cavities wide and deep. 
A tall shrub, rarely arborescent in habit with a short stem 7 or 
8 cm. in diameter, and slender nearly straight or slightly zigzag 
branchlets marked by small pale lenticels, glabrous and light orange- 
green when they first appear, light red-brown and lustrous during 
| their first season, becoming dark gray-brown the following year and 
armed with slender nearly straight light chestnut-brown shining spines 
2.5-4 cm. in length. Flowers at the very end of May. Fruit ripens 
the middle of September and soon falls. 
VERMONT: clay soil on lime stone ridges, Middlebury, Azra Brain- 
erd, September 1900, May and September igor. 
Well distinguished from the other species of this group with 20 
stamens, by its very thin mostly. elliptical leaves, larger flowers and 
early-ripening fruits with usually three nutlets.
