Class B. Lower leaves broad in the centre, tapering towards 

 both ends ; ratio lenoth to breadth between 2 and 3 ; inflorescence 

 leaves linear or similar to, but narrower than, the low^er leaves. 



This class contains 15 types and is intermediate in 

 character between class A with very narrow lower leaves and 

 linear inflorescence leaves, and class C in which the lower and 

 inflorescence leaves are broad. The leaves of all the types are 

 alike in being decidedly broad in the centre, but the amount of 

 tapering towards both ends differs somewhat. The types are 

 further subdivided accordingf to habit. 



Suh-class 1. Internodes short ; all the large leaves form a 

 rosette on the ground. 



Only one type belongs to this sub-class. It is a very free 

 flowering form with broad leaves prolonged into long slender 

 points.
