as a leafy branch, but tapoi- off into a thorn. Prir/i-Ics, such as those on the 

 sterns of Roses and Brain])h's, must not be confounded with thorns. 1'hose are 

 growths from the bark (like hairs or bristU's, only stouter)^ and peel off with 

 it ; while thorns are conntseted with the wood. 



95- Tendrils, such as those of the Grape-Vine, Yirj?inia (h'oepor (¥\<r. 72), and 

 the Melon or Squash, are very sl3nder, lealiess branches, used to enable coitain 



])lants to climb, 

 'i'hey ^'row out 

 straiijlit or nearly 

 so until they reach 

 some neighbouring 

 support, such as a 

 stem, when the end 

 -V hooks around it 

 jr_^ to secure a liold, 

 and the whole ten- 

 dril then shortens 

 itself by coiling up 

 spirally, so draw- 

 ing the growing 

 shoot nearer to the 



supporting object. "When the Virginia Ci-eeper climbs tlio side of a l)uilding, 

 the face of a rock, or the smooth l)ark of a tree, which the tendrils cannot lay 

 hold of in the usual way, their tips expand into a flat plate (as shown in Fig. 

 73, the ends of a tendril magniliod), which adheres very linnly to the surface. 

 This enables the plant to climl) up a smooth surface by tendrils, just as the Ivy 

 and Trumpet-Creeper climb by rootlets (86). 



96. Peduncles or Flower-stalks are a kind of branches, or stems, as is clear from 

 their situation. Thev are eitlior a continuation of the stem, as in the Lilv of the 

 Valley and the Chalcedonian Lily, represented on the iirst page ; or else they 

 rise out of the axil of a leaf, as in the Morning-Glory (Fig. 4). Plainly, what- 

 ever comes from the axil of a leaf must be of the nature of a branch. Ho 



97. Buds, that is axillary buds, are undeveloped branches, as already explained 

 in paragraphs 55 to 58. 



98. The following kinds of branches are all connected with the ground in 

 some way, and most of them act in such a way as to make new plants;
