two of ihe branches have found support, and 

 have coiled spirally, thereby drawing the plant 



near the support ;

Farmers' boys say that a watermelon is ripe when the 

 querl is dead (which, however, may not be true) . What is this 

 querl ? 



135&-. The tendrils of some plants are provided with discs at the 

 ends, rather than hooks, by means of which they attach to a support. 

 Compare the common Virginia creeper ; also the root-like tendrils of 

 the Japanese ampelopsis or Boston ivy (Fig.-1^7~). Can the pupil show 

 that the tendril in Fig. 107. is stem, not root ? 



clematis is shown in Fig. 108. Here 

 the petiolule of the terminal leaflet is acting as a 

 tendril, although all of the petiolules and the pet- 

 iole have the same habit. Leaves, then, may act 

 both as tendrils and foliage.
