VlTACEAE. 



AMPELOPSIS. 

 (Family Vitaceae). 



Rather soft-wooded climbers, 

 sometimes with tendrils only on 

 the upper branches, these opposite 

 the leaf-scars when present and 

 not thickened at tip: foliage de- 

 ciduous. Stems angled or nearly 

 terete, moderate: pith moderate, 

 white, without firmer diaphragms 

 even at the nodes, soon dividing 

 into thin plates by transverse 

 fissures beginning at the peri- 

 phery. Buds subglobose, solitary 

 though collaterally branched in 

 development, sessile, with 2 or 3 

 scales. Leaf-scars alternate, 2- 

 ranked, rounded: bundle-traces, 

 about a dozen in an ellipse, rather 

 small and indistinct: stipule- 

 scars long and narrow. (Cissus). 

 Winter-character references: 

 Ampelopsis cordata (Cissus Am- 

 10, (4), 135, f. 21. 

 A long time will be required to get uniform usage of the 

 name Ampelopsis. Popularly it is applied almost universally 

 to the Virginia creeper and Boston ivy, now called variously 

 Parthenocissus or Psedera by botanists.
