"An intricately branched tree seldom more than 6 m tall, or more
frequently a large shrub 2-5 m in height, with one or several stems:
the bark of the trunk ashy-gray or light brown, slightly fissured
and broken into many thin plate-like scales, or nearly smooth with
scattered patches of oppressed, small scales: branches spreading or ascending, armed with straight or curved, simple or branched, dark chestnut-brown or gray spines 2.5 - 7 cm long; they are intricately divided into numerous, short branchlets which are clothed with the dark reddish-brown bark and marked by small rounded or elongated pale lenticels, forming a narrow, or occasionally rounded or flat-topped head: buds globular, bright reddish-brown; flowers which appear about the first of May and when the leaves are almost fully grown in a few,- (mostly 3-) flowered, more or less pubescent, simply corymbs: lateral pedicels longer than the intermediate only 1.5-3.5 mm
long, more or less pubescent or pilose: calyx obconic pubescent,
the segments glandular-serrate, 6-9 mm long: corolla white,
the divisions nearly round or a little broader than long: stamens
normally 20, 5-7 mm long, pistils 3-5 surrounded at the base
with pale hairs: fruit, which ripens and falls after the
middle of September, globose or depressed-globose 10 -13 mm broad,
10 -12 mm high, yellow, orange -yellow or flushed with red, the flesh
thin and firm; cavity 3-5 mm broad and near as deep surrounded by the
remnants of the stamens: nutlets 3-5, but usually 4, hard and
bony, the walls thick, 7-9 mm long, 4-6 mm measured dorso-ventrally,
with the back ridged and grooved and lateral faces nearly plane:
leaves thin and subcoriaceous, sparsely pubescent when young,
soon glabrous yellowish-green on the upper surface, paler below and
displaying 5-7 pairs of prominent veins: they are ovate,
ovate-lanceoate or round-ovate, 2,5 -12 cm long, 1-6 cm wide, or
occasionally large on vigorous shoots, acute at apex, rounded or
abruptly contracted at the base into a margined
or winged, slightly glandular petiole, 5 mm - 3.5 cm long,
the borders irregularly and doubly serrate and incisely lobed and
serratures minutely glandular tipped: stipules linear to
linear-lanceolate, glandular or on strong shoots foliaceous, lunate,
glandular-serrate caduceus". -Chauncey D. Beadle, 1899.
