108 OF BUDS. 



roots, like the potatoe, are studded with them; in which 

 respect, as Professor Willdenow judiciously observes. 

 Principles of Botany^ p. 15, such roots essentially 

 differ from bulbous ones, which last are themselves 

 simple buds, and produce their shoots, as well as their 

 offsets, either from the centre or from the base. 



The contents of buds are different, even in different 

 species of the same genus, as Willows. The buds of 

 some produce leaves only, others flowers ; while in 

 other species the same bud bears both leaves and 

 flowers. Different causes, depending on the soil or 

 situation, seem in one case to generate leaf-buds, in 

 another flower-buds. Thus the Solandra grandijioray 

 Tr, of Linn. Soc, v, 6. 99- t. 6^ a Jamaica shrub, was 

 tor a number of years cultivated in the English stoves, 

 and propagated extensively by cuttings, each plant 

 growing many feet in length every season, from abun- 

 dance of moisture and nourishment, without showing 

 any signs of fructification. At length a pot of the 

 Solandi^a was accidentally left without water in the 

 dry stove at Kew ; and in consequence of this unin- 

 tentional neglect, the luxuriant growth of its branches 

 was greatly checked, and a flower came forth at tiie 

 extremity of each. By a similar mode of treatment the 

 sanje eftect has since frequently been produced. Seve- 

 ral plants, especially with bulbous roots, which blossom 

 abundantly in their native soils, have hitherto defied 

 all the art of our gardeners to produce this desirable 

 effect; yet future experience may possibly place it
