characters. The Indian types of X. nisfim fall naturalh' 

 into two groups which are easilj^ distinguished in the field : (1) 

 tall plants with open habit and long internodes ; (2) short plants 

 with short internodes. Further sub-division is more difficult 

 as the plants in group (I) are all very much alike, while those in 

 grou[) (2) form an almost perfect series. The best division 

 appears to be that based on the nature of the inflorescence which 

 may be open with sparse flowers, somewhat open with flowers 

 crowded, or compact with ffowers crowded, giving classes A, B, C. 

 The types within the classes are arranged in order, so that the 

 first type of each class bears the most resemblance to the preced- 

 ing class. It was generally a matter of some difficult}' to decide 

 in which class to place such transitional types. The t3"pes within 

 the classes are separated from one another bj^ differences in the 

 arrangement of the leaves, shape, surface and colour of the 

 latter.
