Type XVIIL Plants late ; height 72cms. Leaves inserted 

 at an angle of 45 to 60^ somewhat orbicular ; apex obtuse to 

 rounded ; margin ver}'^ undulate ; surface very puckered ; colour 

 dark blue-green ; average length of petiole 9cms. ; average length 

 of lamina 28cms. ; ratio length/breadth '97. Inflorescence 

 leaves inserted at an angle of 45°, ovate or very broadly elliptical ; 

 apex obtuse or rounded ; margin very undulate ; surface very 

 puckered. Flowers crowded, large. Calyx tubular and loose ; 

 teeth short and obtuse. Corolla, with a slightly divided limb, 

 which is flat and fully expanded ; apicula3 inconspicuous. Capsule

 and umbilicate. 



In this type both cross- and self-pollination are possible, the 

 stamens being approximately equal in length to the style. This is 

 a vigorous, very large-leaved type and is very like type XVII, 

 but the leaves are shorter, more orbicular, darker green and 

 thicker.
