244 CHERRY: GEAN 



$ Twigs slender and pend- 

 ent, yellowish grey pass- 

 ing to deep brown, with 

 no special odour. 



Primus Cerasus, L. Cherry (Fig. 128). The buds are 

 small and nearly obtuse, the lateral ones erect, with dry 

 brown scales; twigs glabrous, with no peculiar odour. 

 Bud-scales smooth, or papillate under the lens. Lenticels 

 scattered. Leaf-scar semi-lunate, with three leaf-traces 

 on rather prominent leaf-bases. 



$J Twigs more erect and 

 stouter, with more promi- 

 nent leaf -bases ; buds 

 larger, more acute, and 

 especially prone to be ag- 

 gregated on the numerous 

 dwarf-shoots. 



Prunus Avium, L. Gean (Fig. 129). P. Avium has 

 larger and more pointed buds, stouter and more erect 

 twigs with prominent leaf-bases, and more numerous 

 dwarf-shoots ; the latter thick and short and much ringed, 

 and with buds clustered at their tips. The lenticels are 

 also more prominent and the leaf-scars rounded triangular. 



The bud begins with two scales, right and left, one 

 overlapping the other at the margins; the third scale is 

 anterior. Then follow about 6 8 others, each oval- 

 pointed, and showing no trace of separation into parts. 

 Further inwards we find the tips more rounded and 

 notched, with a trace of lamina in the notch ; and then 

 obvious leaves with their stipules becoming narrower and 

 more normal (Fig. 32). These leaves are conduplicate and 

 spirally arranged. 



As the bud opens, the outermost scales fall, leaving
