DOGWOOD 169 



two bud-scales fused into one : they have alternate buds, 

 &c., except in Salix purpurea. 



ft Bud-scales at least 3 or 4 ; buds quite sessile. 



Turigs blood-red; buds small, slender, 

 velvety pubescent and compressed, and 

 showing 3 4 scales at most, sometimes 

 apparently fused. 



Cornus sanguinea. Dogwood (Fig. 83). The bright 

 crimson colour is at its best in spring, after the twigs 

 have been exposed to frost, &c. : the older twigs and 

 branches are grey. But the blood-red colour is not 

 always developed, and the predominant colour of the 

 twigs may be olive, touched with red; in these cases 

 other characters will have to be relied on in diagnosis. 

 Older branches olive-brown and fissured. The lenticels 

 are not usually evident till the second year and sometimes 

 spread out and fuse laterally, giving the branches an almost 

 scaly appearance. 



The very narrow and somewhat elongated, sessile buds, 

 about 6 8 mm. long, may be appressed or not, and are 

 often accompanied by an extremely small accessory bud 

 below. Leaf-scars not prominent. 



Several other hedge-shrubs have brown or reddish 

 brown twigs, but none are so vividly blood-red, and all 

 differ in the position of the buds, &c. 



Twigs never brilliant blood-red, and buds 

 not velvety. 



J Shoots with white latex, and like the 

 buds velvety pubescent; lateral buds 

 exposing three scales only ; bud-scales 

 green with brown tips ; older twigs 

 tawny, corky. 



Acer campestre, L. Maple (Fig. 84). The terminal 

 buds (often absent) are small, about 5 mm. long, and
