4. Description of the types. 

 Group I. Playits with p etiolate leaves. 



The five types included in this group fall into two classes : — 



(A) Forms with ovate leaves, types I and II. 



(B) Forms with subcordate leaves, t3^pes III, IV, Y. 



Types I and II resemble each other slightly, but are easily- 

 distinguished b}- the much smaller size of the leaves in type land 

 its more bushy habit. 



Types III and IV are very coarse tall forms. The leaves are 

 almost cordate and very puckered. On superficial inspection 

 III and IV appear to be identical, but they differ in several details 

 connected with the texture of the leaf and the structure of the 

 flower (see description of type IV). 



Type V is most easily distinguished from III and IV by its 

 short habit, light green colour, thin texture and the flat surface 

 of its leaves. The leaves in type V are not as cordate as in types 

 III and IV, Types III, IV and V were all obtained from Burma.
