3 cm. long, 2-2.3 cm. wide, with slender yellow midribs and primary 
veins deeply impressed on the upper side; petioles slender, slightly 
wing-margined at the apex, glandular with numerous dark persistent 
glands, 1.3-1.5 mm. long; on leading shoots leaves ovate, rounded 
or short-pointed at the apex, truncate to subcordate at the base, deeply 
3-lobed, with small rounded or short-pointed lateral lobes, often 4.5-5 
cm. long and wide, with stout petioles wing-margined almost to the 
base and foliaceous lunate coarsely glandular-serrate stipules. Flow- 
ers about 1.2 cm.in diameter on slender elongated pedicels in 3—5- 
flowered compound corymbs; bracts and bractlets linear to oblong- 
obovate, acute or acuminate, coarsely glandular-serrate, reddish 
before falling, caducous; stamens 10; anthers large, rose color; 
styles. 3 ; calyx-tube narrowly obconic, the lobes gradually narrowed 
from broad bases, acuminate, entire or irregularly glandular-serrate, 
reflexed after anthesis. Fruit on slender erect pedicels 1.5—2 cm. in 
length and gradually enlarged at the apex, obovate, full and rounded 
above, abruptly narrowed below, dull orange-green, 1-1.2 mm. in

A straggling semiprostrate shrub usually not exceeding 1 m. or 
very rarely 2 m. in height, with stems 2—3 cm. in diameter and cov- 
ered with ashy gray bark, and slender slightly zigzag branchlets 
dark olive green tinged with red when they first appear, dull red- 
brown and marked by few large pale lenticels during their first sea- 
son, becoming light reddish brown the following year, and armed 
with many straight very slender light red-brown lustrous spines 3-5 
cm. long spreading in all directions and long persistent on the old 
stems, and nearly globose winter-buds 3-4 mm. in diameter and cov- 
ered with orange-red lustrous scales rounded and scarious on the 
margins. Flowers at the end of May. Fruit ripens toward the 
end of September without becoming soft and remains on the 
branches after the leaves have fallen.
