DESCRIPTION OF THE TYPES USED IN 

 HYBRIDIZATION. 



Type II. Plants late, tall ; height 150 cm. ; lower inter- 

 nodes short, upper ones long ; most of the large leaves borne 

 near the ground ; no large leaves in the upper two-thirds of 

 the plant. Leaves petiolate, petiole is slightly alate in the 

 lower leaves, more so in the upper ones ; the wings are 

 decurrent down the main stem for about 2.5 cm. ; leaves inserted 

 at an angle of 90° and bend downwards from the top of the 

 petiole, asymmetric ; shape varies from ovate to lanceolate 

 according to the position on the stem ; venation acute-angled, 

 secondary veins arising at an angle of about 60° ; apex acute ; 

 margin entire or slightly undulate ; colour blue-green ; texture 

 thick ; average length of petiole 6 cm. ; average iength of 

 lamina 49 cm. ; ratio length/breadth 2.5. 1 7i florescence leaves 

 petiolate, petiole not alate, inserted at an angle of 60° — 90°, 

 lanceolate ; apex acuminate ; margin generally entire, some- 

 time undulate. Inflorescence raised, side branches borne at 

 regular distances up the stem, parallel to but not as long as the 

 main axis. Flowers a deep pink colour which does not fade 

 much ; length 45 mm. Calyx slightly globular and inflated, 

 about one-third the length of the corolla ; teeth moderately long 

 and acute. Corolla with an orifice 8 mm. in diameter, a broad 

 tube, and the transition between the tube and the dilated 

 portion abrupt ; limb not very deeply divided with folds at the 

 junctions of the lobe ; lobes very rounded at the base ; apical 

 points short and somewhat reflexed. Capsule much longer than 

 the persistent calyx, conical ; apex blunt.
