On the Physiology of Botany. 9 



I am assured that it is supposed I am trying to alter the pre- 

 sent system, which my sort of botany touches not, or the Lin- 

 nean, on which the whole of my discoveries are really founded. 

 But there are two very different sorts of botany: one is the ter- 

 minology of plants with the sexual system and names ; mine the 

 physiology of plants, and their resemblance to animal life : no 

 two sciences can differ more, though they are both absolutely 

 necessary to each other.

Description of the Plate. 



Fig. 1. The flower-buds, having received their nucleus. 



Fig. 2. The exterior of the buds and branches without the bark. 



Fig. 3. The stem cut longitudinally, the llower-buds proceeding 

 from the line of life at ddd. 



Fig. 4. The stem cut horizontally, showing the flower-buds 

 shooting from the line of life from a to h. 



Fig. 5. The Ulex Europeans, with its blackish buds running up 

 the stem perpendicularly; the lines diverging. 



Figs. 6 and 7. Buds cut open, showing the flowers having taken 

 refuge under their scales, and others running up the 

 stem to increase the number. 



Fig. 8. The root of an herbaceous plant, showing the flower 

 bud, fig. S*, cut open, even below the middle root. 



Fig. 9. The highly-grooved HeracUutn, with the flowers pass- 

 ing up the wood. 



Fig. 10. The Atriplex, with the flowers passing up the grooves 

 in the wood: the leaves are always found rolled in the 

 bark. 



Fig. 11. The alteration of the stem after the leaves have passed 

 up. 



Fig. 12. (I have forgotten to mention the different manner m 

 which the flower-bud and leaf-bud are always discovered 

 in the lower part of the herbaceous plant.) Flower- 

 bud a a; leaf-bud h h. 



• In the old practice of making fruit trees bear, by taking off a circle of 

 the bark down to the wood itself, the communication is complettly cut 

 off between the lower and uppe. parts of the tree by means of the bark, as 

 the wood is left bare all around; yet. the upper part of the tree put" for »i 

 bloom l.uds in great abundance. If the buds had their origin in the bark, 

 the buds must be cut off. or greatly deereased; bat the reverse .s the case. 

 And if the flower-branch proceeded from the alburnum, how could it be 

 supported without the aid of tbe wood .' it would even m its early state break 

 off.
