63 PEOPAGATION OF PLANTSf 



it is a characteristic of the tendril to tarn away from the 

 light and seek the shade, it naturally follows that the 

 fruit of these plants also ripen best when protected from 

 the direct rays of the sun, as is well known to 

 every practical cultivator of the Grape. 



In many herbaceous plants the tendril is 

 but a prolongation of the mid-rib beyond the 

 point of the leaf, as seen in the Pea-vine, and, 

 in a few instances, like that of the Yellow 

 Vetchling {Lathyrus Aphaca), of Great 

 Britain, the whole leaf is but a filiform ten- 

 dril, while in such climbers as the Clematis, 

 Maurandia and Lophospermum the petiole 

 of the leaf may serve as a tendril. 



All twining plants may be considered in 

 the nature of tendrils, being irritable and sen- 

 sitive on one side, enabling them to climb 

 supports and retain an upright position, but 

 the biology of such plants is scarcely of 

 sufficient importance to the practical hor- 

 ticulturist to call. for treatment in detail in a

ages of stems, for they are extensively em- 

 ployed in the propagation of plants, being removed and 

 transferred from one to another with a portion of the 

 surrounding bark and wood attached, and, in such posi- 

 tions, becoming a part of the stem to which they are 

 united. They are also, in some instances, placed in a 

 position where they produce roots, and thus become 

 separate individual plants. Buds may therefore be briefly 

 described as organs enclosing within scales the rudiments 

 of a stem, of leaves or of flowers. It naturally follows 

 that the appendages of highly-developed plants, which 

 are called leaves, are merely the unfolding of buds and a 

 combination of the tissues of the stem or other parts from.
