A narrow shrub thin in habit, 5-6 m high, with many small stems 

 covered with dark gray scaly bark, spreading and ascending branches, 

 and slender nearly straight branchlets glabrous and orange-green 

 slightly tinged with red when they first appear, becoming red-brown 

 and lustrous during their first season and dull gray-brown the fol- 

 lowing year, and armed with numerous, thin, straight, light chestnut- 

 brown shining, ultimately dull gray spines 4-5 cm in length, per- 

 sistent, very numerous and becoming branched on the old stems.

Leaves oblong-ovate to nearly triangular, acuminate, rounded, 

 subcordate or abruptly concave-cuneate at the broad entire or glan- 

 dular base, finely doubly serrate above, with straight glandular teeth, 

 and divided often only above the middle into 4 or 5 pairs of wide 

 acuminate spreading lobes ; about one third grown when the flowers 

 open the 25th of May and then membranaceous, yellow-green, 

 roughened above by short white hairs and pale and glabrous below, 

 and at maturity thin but firm in texture, dull blue-green, smooth 

 and lustrous on the upper surface, pale bluish green on the lower 

 surface, 5-6.5 cm long and 4.5-5 cm wide, with thin yellow midribs, 

 and slender primary veins extending obliquely to the points of the 

 lobes ; petioles very slender, slightly wing-margined at the apex^ 

 sparingly villose while young on the upper side, soon glabrous, 

 3-4 cm in length ; leaves on vigorous shoots subcoriaceous, truncate 

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

 lobed, often 5.5-6 cm long and wide. Flowers 1.5-1.6 cm in diam- 

 eter, on long slender glabrous pedicels, in lax mostly 4-6-fiowered 

 corymbs ; calyx-tube narrowly obconic, glabrous, the lobes gradually 

 narrowed from broad bases, wide, acuminate, entire or occasionally 

 slightly toothed near the middle, glabrous, reflexed after anthesis ;
