of the support, where they assume a different closer stouter 

 growth and produce flowers. 



1. H. Helix. Common Ivy. The varieties of this are 

 numerous and handsome. Flowering specimens, it is said, may 

 be distinguished by the pedicels and calyx being clothed with 

 6- to 8-rayed stellate hairs. But the names are almost suffi- 

 ciently descriptive of the peculiarities of the garden forms, as : 

 pedata, palmata, rugosa, lucida, sagittcefolia, minor marmo- 

 rata, aurea marginata, argentea marginata, etc. There 

 are also green and variegated arborescent forms, and others 

 with white, yellow, or black berries. 



2. H. Canariensis, or Hibernica. Usually known in gar- 

 dens as the Irish Ivy. Stellate hairs of the inflorescence with 

 13 to 15 rays. Algertensis is one of the best green-leaved 

 varieties referred here. Though the variegations are not so 

 numerous and varied, there are some very desirable, generally 

 of more robust and vigorous growth than in No. 1 : pdllida, 

 maculata, argenteo-marginata, Cavendishii, etc. ; arborescens 

 and cordifolia are c Tree Ivies.' 



3. H. Roegneriana or Colchica. Giant Ivy. Inflorescence 

 furnished with 2-lobed scales, each lobe again divided into 7 

 to 10 teeth. The leaves of this form are very large, thick 

 and leathery. There is a variety, arborea, both green and 

 variegated.
