Coffea Jenkinsii Hook. f. 

 Coffea ligustroides S. Moore. 

 Coffea khasiana Hook. f. 



Coffea Jenkinsii Hook. f. Fl. Brit. Ind. 3 (1882) 155. 

 A glabrous shrub. Leaves 1.2 cm. to 4.0 cm. wide by 7 cm. 

 to 14 cm. long, elliptic-lanceolate to caudate-acuminate, base acutely 

 narrowed, apex attenuated, apex 1.5 cm. long; petiole 0.5 cm. long; 

 lamina broadest at the middle or below; 5 to 6 paired veins of the 

 first rank; stipules 0.4 cm. long. Flowers axillary; corolla-tube 

 longer than the lobes, mouth glabrous, lobes acute, 4 in number; 

 calyx quadridentate. Fruit ellipsoid, i cm. long by 0.5 cm. broad. 

 Diagnostic Characters of the Species: — Closely allied to C. khasi- 

 ana Hook f. but C. Jenkinsii Hook. f. is almost entirely glabrous, 

 only the younger shoots being puberulous. Leaves narrower, with 

 fewer prominent veins. Flowers larger. Fruit and seeds different, 

 — the seeds of C. Jenkinsii Hook. f. being 0.83 cm. long, ellipsoidal 

 in form. This species resembles, in habit, the non-economic species 

 C. salicifolia Miq. of Java. 



Geographical Distribution: — Himalaya Region; Khasia Mts. (Alt. 

 900 M. to 1200 M., Jenkins, Griffith — Kew Distrib. No. 3015); 

 East Bengal. 



History : — This species was collected by Jenkins and Griffith about 

 1880. Although its seeds are of a fair quality, it has not been ex- 

 tended beyond local cultivation. 



Use : — Mainly as a substitute for the seeds of C. arabtca L.
