deciduous stipules. Flowers 1.8-2 cm. in diameter, on long slender 

 pedicels, in small compact mostly 5-7-flowered corymbs, the elongated 

 lower peduncles from the axils of upper leaves; calyx-tube broadly 

 obconic, the lobes separated by wide sinuses, gradually narrowed 

 from the base, short broad, acuminate, irregularly glandular-serrate 

 below the middle, reflexed after anthesis; stamens 10; anthers pale 

 pink; styles 3-5, surrounded at the base by a broad ring of pale tomen- 

 tum. Fruit ripening in October, on stout spreading pedicels, in 

 few-fruited clusters, subglobose rather broader than long and flattened 

 at the ends to slightly obovate, dull red, pruinose, marked by dark 

 dots, 1-1.2 cm. in diameter; flesh green, dry and hard; calyx little 

 enlarged, without a tube, with a wide shallow cavity, and small reflexed 

 closely appressed lobes; nutlets 3-5, gradually narrowed and rounded 

 at the ends, rather broader at the base than at the apex, ridged on 

 the back, with a broad high grooved ridge, 7.5-8 mm. long and 5.5-6 

 mm. wide. 



A tree sometimes 10 m. high, with a trunk 3 dm. in diameter, 

 covered with dark scaly bark, large ascending branches, and stout 

 slightly zigzag branchlets light orange-green and marked by pale 

 lenticels when they first appear, becoming dark chestnut or orange-

 following year, and armed with numerous slender straight or slightly 

 curved purple shining spines 3.5-4 cm. long.

Leaves ovate, acuminate, abruptly or gradually narrowed and 

 cuneate at the base, finely often doubly serrate, with straight glandular 

 teeth, and slightly divided into 4 or 5 pairs of small acute spreading 

 lateral lobes; about half-grown when the flowers open at the end of 

 May and then thin, yellow-green and slightly hairy along the midribs 

 above, paler below, and at maturity thin, light yellow-green and 

 lustrous on the upper surface, pale yellow-green on the lower surface,

 with minute occasionally persistent glands, 2-2.5 cm. in length. 

 Flowers not more than 1.5 cm. in diameter, on long slender pedicels,
