(/>) Lower internocles short, upper ones gradually elongated ; 

 nian}^ large leaves borne close to the ground, a few continued up 

 the stem. 



Of the four types belonging to tljis sub-division type XIII 

 forms a transition between sub-divisions (/>) and (c). Only a few 

 leaves are borne on the ground and several laige ones appear on 

 the main stem. In its open habit this t3'pe resembles t37pes XIV 

 and XV. 



Type X is a short bushy form easily distinguished from the 

 other types in this sub-division by its height and the surface 

 of its leaves. Types XI and XII resemble each other very 

 closely and only dift'er in some minor details. Type XII 

 is later than type XI with deep pink flowers, while the flowers of 

 the latter are white. The structure of the flowers is also 

 somewhat different.
