VIBURNUM 243 



Ace7^ campestre and Ulmus campestris are often shrubby 

 in hedges, &c., and have a great tendency to form tawny- 

 grey corky periderm, which is ridged and furrowed on the 

 branches : it is less rugged than that of Sambucus, but 

 there are certain resemblances. Both are much more 

 woody and stiffly branched ; and the buds, leaves, flowers 

 and fruit differ entirely (see pp. 160, 185). 



CJ CJ Twigs not thick nor pithy; leaves not 



compound, and lenticels not prominent. 



§ Twigs greyish or whitish, mealy; buds 



naked; leaves large oval, grey-green, 



hairy; flowers white in dense corymbs; 



fruit fleshy, flattened, red to black. 



Viburnum Lantana, L. Wayfaring Tree. An erect 

 shrub, common on chalk, 10 — 15 feet, abundantly but 

 loosely branched. Twigs more or less angular at tips, and 

 nearly white with grey, scurfy, stellate hairs. Branches 

 yellowish-brown, passing to grey-brown, with long fissures. 

 The flattened oval fruits, mealy shoots and foliage, and 

 the naked elongated buds are very characteristic. 



§§ Twigs and foliage not mealy; buds 

 not naked; and fruit not flattened. 

 $ Shoots slightly angular; ttvigs shin- 

 ing pale-brown or greyj leaves lobed 

 and with glands on their petioles. 

 Flowers in dense cymes; the outer 

 ones mtich larger, barren and white. 

 Fruit scarlet. 



Viburnum Opul a s,h. Guelder Rose (Fig. 123). A shrub 

 or small tree, up to 10 — 12 feet high, easily recognised by 

 its glandular petioles, broad lobed leaves, and the larger 

 white barren flowers at the edges of the umbellate cymes. 

 Bark yellowish grey, fissured ; branches weak, tawny -grey. 

 Suckers long and wand-like. The buds exhibit at most 

 two scales on the outside.
