Twigs round, slender, more or less 
pubescent: pith small, round, 
somewhat brownish, usually ex- 
cavated. Buds small, solitary or 
collaterally multiple or developing

Like the related genus Lonicera, Symphoricarpos pre- 
sents the phenomenon of two types of pith, excavated and 
continuous, in different groups of species that are referred to 
‘it; in this respect recalling Jasminum, some species of which 
have a continuous pith, while the pith is exquisitely cham- 
bered in others. 
1. Pith continuous. (Coral berry). (1). §. orbiculatus. 
Pith excavated. (Snowberry). 2. 
2. Buds small (2 mm. long): twigs glabrate. S. racemosus. 
Buds moderate (3 mm.): puberulent. (2). S. occidentalis. 
Buds large (4 mm.). (Hybrid snowberry). XS. Heyeri.
