658 A. E. Verrill—The Bermuda Islands. 
Several other species are cultivated, as the Blue Aloe (A. Mexicana 
Lam.); A. var. variegata Hort.; A. striata Z.; A. xylonacantha Salm. 
These woody endogenous plants, though not real shrubs, are put 
here for convenience. 
c.—The more prominent Climbing Plants or Vines. 
Several fruit-bearing vines have been included in a previous list 
(a) with the fruit trees. Among these are the Passion-flowers, the 
Grape, ete. Others are included in the list of seaside plants. 
The following list comprises the more important naturalized and 
cultivated species, and some natives, but many others are cultivated 
in the larger gardens. 
Sweet Clematis. (Clematis lammuta I.) 
Grows luxuriantly in some places ; cultivated. European. 
Japan Clematis. (C. Japonica Thunb.) 
Several varieties of this fine species are cultivated in some gardens. 
Woodbine; Virginia Creeper; False Sarsaparilla. (Vitis hederacea 
Ehr.= Ampelopsis quinquefolia Mich.) 
This common North American vine, which is native about Wal- 
singham, is often cultivated. 
Japanese Ivy. (Vitis inconstans Miq. = Ampelopsis tricuspidata 
Sieb.; tridentata Thun.; Veitchi Hort.) 
Cultivated in gardens, for covering walls. 
Poison Ivy ; Poison Vine. (Rhus towicodendron L.) 
Native and very common in thickets and swamps. Described by 
the earliest writers with correct accounts of its poisonous qualities 
and its variable effects on different individuals.* Leaves trifoliate, 
flowers greenish, fruit green, in loose clusters ; the sap is not milky. 
Adheres to trees and walls, like the true ivy, by root-like tendrils. 
It is liable to be mistaken for the Japan Ivy, some varieties of the 
latter resembling it in foliage and habit. 
* A solution of sugar of lead (lead acetate) in weak alcohol is one of the best 
remedies for the irritating poison of this plant; but zine sulphate and copper 
sulphate are, perhaps, equally useful, and safer to use. The poison is an oil, 
allied to croton oil. Dry heat is also useful. The powder of bismuth subnitrate 
is useful to allay the itching.
