The differences, too, are inherited and selection can be made to 
ies. f ; 
in (1) the relative length of the capsules and internode, (2) 
the position of the leaves—whether occurring in pairs or in 
threes or fours and whether opposite or alternate. From com- 
binations of these variations the following types with refer- 
ence to the inflorescence and fruiting system, can be distin- 
guished :— 
(i) Plants with internodes longer than the capsules, the 
latter occurring in opposite pairs. 
ii) Plants with internodes longer than the capsules, and 
the latter occurring in fascicles of threes. In this type we get 
a decided whorled appearance, especially if the leaves arise in 
threes from the same point of the stem (Plate XI). 
(iii) Types in which the internodes are not longer than 
the capsules. 
(iv) Types in which the capsules are as long as the inter- 
nodes and in which the leaves are alternate. The capsules 
when in fruit a main axis completely occupied by the fruits in 
* Spiral arrangement. These types are well known to Burmese 
cultivators who have specific names for each of them, eg. 
“ gw 
round-about ” to (ii), and “ tet-kyaw ” or “ climb and jump”

In shape the capsule shows very considerable variation 
from type to type and generally also among the capsules on 
shape, e number of cells also varies from two to ten and 
this variation is often found on one and the same plant. The 
shape of the capsule depends to a great extent on the number 
of cells. When there are only two or four the shape is oblong- 
‘ompressed with a quadrilateral section ; when the number of 
cells iS greater than four the capsule assumes a more or less 
Colour of the Vegetative Parts.—This varies from light
