CAPRIFOLIACEAE. 



SYMPHORICAKPOS. 

 (Family Caprifoliaceae). 



Rather small shrubs: deciduous. 

 Twigs round, slender, more or less 

 pubescent: pith small, round, 

 somewhat brownish, usually ex- 

 cavated. Buds small, solitary or 

 collaterally multiple or developing 

 lateral branches the first season, 

 ovoid-oblong, more or less com- 

 pressed, sessile, with about 3 pairs 

 of keeled scales. Leaf-scars op- 

 posite, half-round, small and 

 mostly torn, raised, partly con- 

 nected by transverse ridges: 

 bundle-trace 1, indistinct: stipule- 

 scars lacking.

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). S. 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). X S. Heyeri.
