L/ 



CrSSUS L. The Cissus. Lin. Syst. Tetrandria Monogynia.

 is hardy in British gardens.

 Cissus, or Ivy Vine.

p. 694. 

 Engravings. Lam. 111., t. 84. fig. 2. ; and our 



fig. 190. 



Spec.Char.,Sfc. Leaves bipinnate, smooth ;

 A deciduous climber. Levant. Stem

 Berry, ?. 



We have only seen the plant bearing 

 this name in the collection of Messrs. 

 Loddiges, from which our figure is taken, 

 and which, as it does not agree very well 

 with the specific character, is perhaps 

 not the true plant. At all events, the 

 plant figured is handsome, and as vigo- 

 rous and hardy as Ampelopsis bipinnata. 190. Cissus orientalis. 



Order XVII. XANTHOXYLA^CE^. 



Ord. Char. Floivers unisexual, regular. Calyx in 3 5 divisions. Petals 

 the same number, longer than the calyx ; aestivation generally twisted. 

 Stamens equal in number to the petals ; in the female flowers wanting or 

 imperfect. Ovary with as many carpels as there are petals. Fruit either 

 berried or membranous. Trees or shrubs, chiefly natives of warm climates. 

 {Lindl.) 



Leaves compound, alternate or opposite, without stipules ; abruptly or 

 unequally pinnate ; with pellucid dots. Floivers axillary or terminal ; 

 grey, green, or pink. The species in British gardens are comprised in 

 three genera, which are thus contradistinguished : 



Xantho'xtlum L. Flowers bisexual. Carpels 1 5, 2-valved. Leaves 



abruptly and impari-pinnate. 

 PteYea L. Flowers bisexual. Fruit compressed, 2 3-celled ; cells winged. 



Leaves of 3 leaflets, rarely of 3 leaflets. 

 Aila'ktus Desf. Flowers polygamous. Carpels 3 3, membranous. Leave?
