TUBERS. 



The tuber of a Cyclamen (a development originally from the caulicle or 

 tigellum) is essentially the same as the rootstock, differing only in its more or 

 less globular form. It throws off feeding roots from its base or its sides, and it 

 forms a bud or buds at the top. Its fleshy tissue is laden with starch and 

 building material for new growth.
