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, arid 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 and 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, 3 6 mm. long, not viscid or 

 ferruginous ; shrubs with large glossy ovate- 

 lanceolate leaves. 



Twigs and buds green. 



Prunus Lauro-cerasus, Lois. Cherry Laurel. The 

 bud-scales are stipular, and the young leaves conduplicate
