1-[4 STUDIES lis' INDIAN TOBACCOS. 



Type XVIII. Plants somewhat early, later than types 

 XIV and XV, dwarf ; height 97 cms. ; habit open ; internodes 

 moderately long, except the two or three lowest ones, so that 

 nearly all the leaves are raised above the ground. Leaves sessile, 

 inserted at an angle of about G0° and droop from a point about 

 one-third from the base of the leaf ; shape varies from elliptical 

 to lanceolate according to the position of the leaf on the stem, 

 lamina much narrowed in the basal third of the leaf; leaves 

 sliohtly amplexicaul, decurrent for about I'S cms., slightly auricu- 

 late ; venation acute-angled, secondary veins arising at an angle 

 of about 45° ; apex acute to acuminate ; margin shghtly undulate, 

 the lamina more or less undulate in the basal portion according to 

 the position of the leaves on the stem ; colour light green ; tex- 

 ture thin; average length 45-5 cms.; ratio length/breadth 3 0. 

 Infiorescence leaves sessile, inserted at an angle of 90°, linear ; 

 apex acuminate ; margin entire or slightly undulate ; leaf flat or 

 somewhat undulate. Inflovesceuce raised above the leaves; side 

 branches borne at regular intervals up the stem from the base 

 upwards, almost as long as, and somewhat parallel to, the main axis. 

 Flowers white, very pale pink in the bud, short (length 40 mm.). 

 Calijx tubular, less than half the length of the corolla ; teeth 

 moderately long and acute. Corolla with a very small orifice 

 (7 mm.), slender; the transition between the tube and the dilated 

 portion abrupt ; limb deeply divided with folds at the junctions 

 of the lobes ; lobes very rounded at the base ; apical points short. 

 Capsule a little shorter than the persistent calyx, conical ; apex 



pointed. 



The anthers burst in the bud when just above the stigma. 

 In the open flower the stamens are decidedly above the stigma 

 and project beyond the orifice of the corolla.
