RHODODENDRON, ETC. 149 



as in Holly, and have a grey-green appearance matching 

 the ash-grey bark and twigs. 



Q. Suber, the Cork Oak, with similarly grey-green 

 hard foliage, differs in its corky bark, and its acorns. 



Daphne Laureola, L. Spurge Laurel (Fig. 69), a 

 small bush with very supple, tough branches, and shining, 

 coriaceous, lanceolate leaves, also has its buds chiefly at 

 the tips of the twigs. The bud-scales are, however, not in 

 5 ranks, and are otherwise different. 



** Buds not aggregated at the tips of the 

 twigs, and scales not in 5 ranks and dry. 



t Buds ferruginous, viscid, ovoid-conic, pointed, 

 and exhibiting about 10 12 long, triangular- 

 ovate, acuminate scales, spirally imbricate ; 

 the flower-buds larger. 



Rhododendron ponticum, L. Rhododendron, Rose Bay. 

 The terminal buds are usually flower-buds, and relatively 

 very large, each bud-scale having a flower-bud in its axil. 



The lateral leaf-bud begins with a scale on each flank 

 to right and left, the third scale next the subtending leaf. 

 The young leaves are revolute and spirally arranged. 

 The dark laurel-like leaves remind one of Prunus Lusi- 

 tanica arid P. Lauro-cerasus, but the larger viscid buds at 

 once distinguish them ; Aucuba, with somewhat similarly 

 shaped but opposite leaves, is quite different, and all differ 

 from the true Laurel (Laurus). See pp. 144 and 150. 



ft Buds small, 36 mm. long, not viscid or 

 ferruginous ; shrubs with large glossy ovate- 

 lanceolate leaves. 



Twigs and buds green. 



Prunus Lauro-cerasuSy Lois. Cherry Laurel. The 

 bud-scales are stipular, arid the young leaves conduplicate
