'I consider (says T. A. Knight, Esq. in a letter 

 to the author,) a bulb to differ from an ordinary 

 bud, only in having a reservoir of a different form 

 attached to it. The bud of a tree, or of the tuber- 

 ous root of a potatoe, is attached to a mass of 

 alburnum and bark, from which, when it germi- 

 nates, it draws its requisite nutriment. A bulbous 

 root, such as the common onion, has numerous 

 thick and fleshy scales, which in their incipient 

 state, might have extended into leaves, but which, 

 instead of extending themselves, remain short and 

 are distended by becoming reservoirs of the true 

 sap of the plant, as the bark and alburnum were 

 in the cases before- mentioned.' 



He observes, also> *Buds of every kind have 

 their attached reservoirs, without which they can- 

 not live and extend themselves. Some species of 

 trees and herbaceous plants possess a power which 

 others do not, of re- producing buds upon the surface 

 of their alburnum. It is, however, the unanimous 

 opinion of the continental naturalists, and of the 

 English and Scotch, with the exception of myself, 

 that all buds originate from the Medulla ; and it is 

 true, that in all cases> almost, a bud may be traced 

 to the Medulla ; but I have, in a great many in- 

 stances, occasioned buds to be generated upon the 

 smooth surface of the alburnum ; and I have often 

 seen them thus produced naturally.' 



If the bulbs which are produced on the stems of 

 this magnificent Lily, be planted in the borders as 

 soon as they fall, or can be easily detached, they 

 will grow, and in most cases blossom at three years 

 old, but stronger in the fourth year.
