Small trees or shrubs for our

 ally evergreen. Twigs moderate, 

 swollen at the nodes, more or 

 less zig-zag with elongated inter- 

 nodes, subterete or angled: pith 

 somewhat 3-sided, continuous, pale 

 or greenish. Buds woolly, super- 

 posed, sessile, sometimes small 

 and at first concealed by the leaf- 

 scar, the end-bud lacking. Leaf- 

 scars usually alternate, raised, 

 from nearly round or deltoid be- 

 coming narrowly U-shaped by 

 tearing of the articular mem- 

 brane: bundle-traces 3: stipule- 

 scars or remnants minute, at the 

 upper angles of the leaf-scar.
