((') All the internodes moderately long, only two or three 

 leaves on the ground. 



Five types (XIV to XVIII) belong to this sub-division. 

 The first three are easily distinguished from the other two by 

 their nmch greater height, and the greater elongation of their 

 inflorescence. Type XIV bears some resemblance to type XIII 

 of the last sub-division and is distino^uished from XV and XVI 

 by the width and paucity of its leaves. Types XV and XVI are 

 very easily distinguished from each other by the shape and surface 

 of their leaves, t^'pe XV having more undulate leaves with more 

 acuminate apices than type XVI. Type XVII is a short type 

 with a peculiarly flat-topped inflorescence and very few leaves. 

 The most distinctive character of type XVII is the shape of its 

 leaves in which it shows a resemblance to class B.
