rounded at the base, coarsely serrate, more deeply lobed and often 

 6-7 cm. long and 5-6 cm. wide. Flowers 1.5-1.8 cm. in diameter on 

 short stout pedicels thickly coated with long white glandular hairs, 

 in small compact 3-5-flowered corymbs, with conspicuous glandular 

 bracts and bractlets; calyx-tube narrowly obconic, villose, the lobes 

 abruptly narrowed from broad bases, long, foliaceous, laciniately 

 glandular-serrate above the middle, glabrous on the outer surface, 

 slightly hairy on the inner surface, reflexed after anthesis; stamens 

 10; anthers cream color; styles 5, surrounded at the base by a narrow 

 ring of pale tomentum. Fruit ripening in October, on stout elongated 

 hairy pedicels, in mostly 2-4-fruited clusters, subglobose to short- 

 oblong, green slightly blotched with red (September 6), about 

 1 cm. in diameter; calyx little enlarged, with a short tube, a wide 

 shallow cavity broad in the bottom, and spreading often deciduous 

 lobes; flesh thin, green, dry and hard; nutlets 5, gradually narrowed 

 and rounded at the ends, narrower at the apex than at the base, 

 5-5.5 mm. long and 3.5-4 mm. wide. 



A shrub 1 m. high or less, with small contorted intricately branched 

 stems, and slender branchlets orange-green and coated with long 

 white hairs when they first appear, still more or less hairy and dark 

 chestnut brown at the end of their first season and dark gray-brown 

 and glabrous the following year, and armed with numerous slender 

 straight spines 1.5-2 cm. long.

Leaves broadly ovate and rounded at the base to rhombic, acute 

 and often short-pointed at the apex, sharply often doubly serrate, 

 with straight glandular teeth, and divided above the middle into 3 

 or 4 pairs of short broad acute lobes; nearly fully grown when the 

 flowers open about the 20th of May and then thin, light yellow-green 

 and roughened above by short white hairs, and slightly hairy below on 

 the slender midribs and primary veins, and at maturity thick, yellow- 

 green and scabrate on the upper surface, scabrate and still hairy 

 on the lower surface, 4-5 cm. long and 3.5-4 cm wide; petioles stout, 

 narrowly wing-margined to below the middle, glandular, with numerous 

 persistent glands, villose early in the season, becoming glabrous, 

 1.5-2 cm. in length; leaves on vigorous shoots broadly ovate, trun- 

 cate or rounded at the base, coarsely serrate, more deeply lobed and 

 often 6-6.5 cm. long and broad, with stout broadly winged conspicu- 

 ously glandular petioles. Flowers 1.8-2 cm. in diameter, on stout
