CHAPTER VIII. 



ARRANGEMENT OF LEAVES IN THE BUD. 



Not necessarily that of the bud-scales Leaves decussate distichous 

 spiral Folding of leaves in bud Conduplicate Direction 

 of folding Convolute Involute Revolute Plicate Plane. 



THE arrangement of the young leaves in the interior of 

 the bud is by no means necessarily the same as that of the 

 bud-scales, though the exceptions chiefly concern those 

 cases where the scales are stipular. 



In the Juniper the leaves in bud are throughout in 

 whorls of three (Fig. 38).

Fig. 38. Plan-diagram of bud of Juniper, consisting of alternate 

 whorls of three leaves each, the outer serving as bud-scales. 



Fig. 39. Plan-diagram of a bud with the outer bud-scales opposite, 

 passing into a spiral. The scales are reduced leaves, e.g. Willow. The 

 leaves are neither folded nor rolled.
