LILAC. SNOWBERRY 245 



JfJt Shoots and twigs round, smooth, 

 more or less grey; buds with several 

 visible scales; leaves not lobed; flowers 

 not of two kinds, and fruit not red. 



-T- Twigs ending in a pair of rather 

 large olive-green or brownish buds; 

 branches grey. Leaves more or less 

 cordate, on long petioles. Flowers 

 lilac, in pyramidal inflorescences. 

 Fruit a capsule. 



Syringa vulgaris, L. Lilac (Fig. 12). A shrub or small 

 bushy tree, 10 15 feet high, with a besom-like habit, 

 sending up numerous erect, round, yellowish-grey or olive 

 twigs with conspicuous lenticels, and often forked in a 

 pseudo-dichotomous manner. Bark grey to grey-brown, 

 fissured and scaly. 



Olive-green buds, with greenish scales edged with 

 brown, are met with in several species ofPyrus (pp. 196 7) 

 and Acer (p. 219). The former are distinguished at once 

 by the scales being spirally inserted, but in Acer they are 

 opposite and decussate as here. With plants in leaf and 

 flower there is no difficulty : in the winter state the 

 periderm and bark are diagnostic, but a sharp mark of 

 recognition is also found in the leaf-scars, which in Acer 

 have three, in Syringa only one elongated leaf-trace 

 bundle. Moreover Acer has a terminal bud. 



4- -T- Buds not paired at the end of the 

 twigs; leaves not cor date nor long- 

 stalked; flowers if lilac not in 

 bunches; and fruit not capsular. 



8 Twigs shedding fine silky cortical 

 fibres, pale grey to yellowish, 

 thin. Leaves glaucous beneath. 

 Flowers rosy, few, in the leaf 

 axils. Berries white. 



Symphoricarpos racemosus, Mchx. Snowberry (Fig. 

 124). A small bush, 3 6 feet [or more] high, with
