ORIGIK AKD KINDS OF BUDS. 29 



in other words, it puts forth a bud, this in turn another ; 

 these, however, are only single cell buds, but as we 

 advance upward in the scale we find plants composed of 

 an aggregation of cells, therefore compound in their 

 structure, and their buds, assuming the parent form, are 

 also made up of a number of cells, arranged in regular 

 order, through the controlling influence of what is called 

 the formative or living principle. Keeping the fact 

 in mind that new cells are always the product of other, 

 or parent cells, and that in the re-arrangement of cell- 

 matter, or growth, the new cells preserve their typical 

 form, we can readily understand how buds, even of the 

 most complicated structure, may, under favorable con- 

 ditions, be produced from living organizable vegetable 

 matter, on or within any part or appendage of a plant. 

 It is true that, when plants are under normal conditons 

 and with room for full development, they produce buds 

 uniformly at certain points and not elsewhere ; but it is 

 seldom that a plant is so favorably situated as .got to be 

 disturbed at some period in its life; consequently, ajmor- 

 mal growths may become hereditary through the oft- 

 recurring influence of abnormal conditions. In a state of 

 nature, there is usually more or less crowding among 

 plants, and parts are disturbed, broken, or destroyed. 

 The larger animals trample upon the small and young 

 plants, or later in life browse upon the stems and 

 branches, while insect enemies sting, cut and wound 

 plants in various ways, consequently there is always a 

 struggle for existence, which begets a necessity for a de- 

 parture from what, under other conditions, would be 

 the natural order of growth. 



There are as many dijSjerent forms of buds, as there 

 are different species of plants, but for the sake of con- 

 venience, they may all be arranged under five groups, 

 viz. : The (1) terminal, (2) axillary, (3) accessory, (4) 

 fruit bud, (5) adventitious. Buds, although of various
