 adapted for bowers or trellis-work. It may be increased by 

 ripened cuttings, and slips of the root, planted under a hand- 

 glass, or by laying down the young shoots. The other species 

 will grow freely in a mixture of loam and peat, and ripened 

 cuttings will strike root in a pot of sand, under a hand-glass.

 white lines, which elegantly contrast with the smooth green bark, 

 not unlike what is observed in A^cer strialum. This is most 

 probably the Funis viminalis of Rumph. amb. 3. t. 2.
