roots of the preceding summer had already begun to decay 

 and were completely emptied of starch. 



The leaves are arranged in a f spiral. They vary some- 

 what in form and size, but with no apparent regularity in the 

 variations, either as to arrangement or stage of development. 

 The principal bud is placed in the axil of the uppermost 

 foliage leaf, and, as mentioned, it had already developed several 



foliage leaves by the middle of 

 the summer ; as the result of 

 further increases during the sum- 

 mer, a rosette of 6 — 8 leaves 

 is formed. The growth of the 

 bud ceases temporarily during 

 the autumn, some of the leaves 

 remaining as scale-leaves, to 

 form a protective covering for 

 the younger growth, which next 

 spring will develop into ordi- 

 nary foliage-leaves. These scale- 

 leaves may be found at the 

 ba>^e of the spring-rosette as 

 lale as July, but only in a vrry 

 damaged state. Unfortunately,

 buds gathered during the win-

 contain starch, as is the case with kindred

The principal bud has sometimes been found to develop 

 its peduncle during the same year as the parent shoot, and 

 this even on plants showing relatively poor development, so 

 that the plant may have two inflorescences flowering about 

 the same time. Vegetative augmentation-shoots may be 

 formed by small leaf-rosettes developed from some of the
