Small shrubs, loosely branched: 

 deciduous. Twigs terete or some- 

 what 5-lined from the nodes, 

 slender, zig-zag, red: pith small, 

 pale or light brown, continuous. 

 Buds small, superposed, the upper 

 of each series often developing 

 the first season or slightly 

 stalked, ovoid or oblong, with 

 about 4 scales. Leaf-scars alter- 

 nate, 2-ranked, small, half-round 

 or triangular, slightly raised: 

 bundle-traces 3 or subconfluent:

Stephanandras are slender 

 spiraea- or kerria-like shrubs dif- 

 fering from the former in some 

 small respects and from the latter 

 in their red and not bright green 

 twigs. Winter-characters of 8. 

 flexuosa are given by Shirasawa, 



247, pi. 4, and of 8. incisa by Schneider, f. 137.
