Identification. Lin. Gen., No. 147. ; Dec. Prod., 1. p. 627. ; Don's Mill., 1. p. 689. 



Derivation. Kissos is the Greek name of the ivy, which these plants in some manner resemble. 



Gen. Char., $c. Calyx almost entire. Petals 4, falling off separately. Ovary 4-celled. Berry 



14-seeded. (Dec. Prod., i. p. 630.) Climbing plants, chiefly ligneous, with simple, trifoliate, or 



palmate leaves, and cymes or corymbs of small flowers, greenish, yellow, and sometimes purplish. 



Above 70 ligneous species are described in Don's Miller, a few of which are green-house plants, and 



already introduced into British gardens. 



" t_ 1. C. orientdlis Lam., figured in Lam. III., t. 84. fig. 2., is a native of the Levant, and, accord- 

 ing to Sweet's Hortus Britannicus, was introduced in 1818. It is a green-house climber ; and, being 

 considered tolerably hardy, it might be tried against a conservative wall. 



4. 2. C. quindta Ait., a native of the Cape of Good Hope, introduced in 1790, has palmate leaves, 

 and is treated as a green-house plant. 



fl_ 3. C. antdrctica Vent. Choix, t. 21., and our fig. 147, is a native of New Holland, whence It was 

 introduced in 1790, and is commonly called the kangaroo vine. It has large, cordate, serrated, smooth- 

 ish leaves, and but seldom, if ever, flowers in our green-houses. It is, probably, as hardy as other 

 New Holland shrub*. 



L 4. C. capensis Willd. is a native of the Cape of Good Hope, introduced in 1792. 

 ft_ C. \itiglnca, (Jig. 148.), C. quinquefblia C/#.149.), and, probably, other species now kept In our 

 green-houscs. and some even in our stoves, might, probably, prove half-hardy, if judiciously treated. 



CHAP. XXVII. 



OF THE HALF-HARDY LIGNEOUS PLANTS OF THE ORDER 



GERANIA N CE;E. 



WE introduce this order chiefly for the sake of recommending a trial of some of the hardier 

 varieties of the common pelargonium ; the roots of which, at least, will live through the winter at 

 the bottom of a wall, if the soil be kept quite dry during that season, and covered with straw. The

following sorts may, perhaps, be chosen for a trial, in preference to some others : P. liarringtbnr'/i 

 cucullatum (fig. 150.), macrfenthon, mcgalanthon, calaniistratum, guercifblium, peltatum, zonalc 

 (fig. 151.}, Bentinckinnwrn, inquinans (.fig. 152.)
