166 BUDS AND STIPULES 



more advanced early in spring than the leafy ones, as 

 they flower in spring. 



In the Quince (Pyrus Gydonia) we have the fol- 

 lowing series : 1 . The scales of the winter-bud are 

 very broad, short, deeply trifid or almost tripartite, 

 deep brown or black ; the lateral lobes are the largest, 

 and represent the stipules. 2. Fascicles of leaves 

 are produced along the sides of the previous year's 

 wood, and the stipules on the outer leaves are re- 

 duced to small blunt teeth. 3. Those towards the 

 centre of the fascicle bear subulate or linear sti- 

 pules, with a distinct midrib. 4. On the base of the 

 elongating shoots the stipules are lanceolate, shortly 

 stalked, acute, and one-nerved. 5. The stipules gradu- 

 ally widen on succeeding leaves, till they become 

 broadly and obliquely reniform, dentate, with the midrib 

 nearest the anterior side and running into an acute point, 

 copiously reticulate, shortly petiolate, and foliaceous, 

 with large auricles passing round the axis until they 

 meet on the opposite side. The scales of the winter- 

 bud persist for some time, at least, after the expansion 

 of the leaves, and offer some protection. There would 

 be no need, nor room, for large stipules in the fascicles 

 of leaves, as the older leaves protect the younger. 



Again, in the Currant (Ribes saiu/uineum) about five 

 (more or less) of the scales of the winter-bud are ovate, 

 acute, trinerved, rather membranous, and consist of 

 the dilated base of the petiole, the lamina being repre-
