Genus III. 
CYSSUS L. Tue Cissus. Lin, Syst. Tetrandria Monogfnia. 
Identification. Lin. Gen., No. 147.; Dec. Prod., 1. Pp. 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. Be. 
1—+4-seeded. (Dec. Prod., i. p. 630.) Climbing plants, chiefly ligneous, with fp ery 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, 
™@ 1.C. orientalis Lam., figured in Lam. Ii., t. 84. fig. 2., is a native of the Levant, and, accord- 
ing to Sweet’s Hortus Britannicus, was introduced in 1818. It is 2 green-house climber ; and, being 
considered tolerably hardy, it might be tried against a conservative wall. 
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. 
&_ 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, errated, smooth- 
ish leaves, and but seldom, if ever, flowers in our green-houses. It is, probably, as hardy as other 
New Holland shrubs. 
’ g 4 C. capénsis Willd. is a native of the Cape of Good Hope, introduced in 1792. 
& C. viti, a, (fig. 148.), C. quinguefolia (fig.149.), and, probably, other species now kept in our 
green-houses, and some even in our stoves, might, probably, prove half-hardy, if judiciously treated.

OF THE HALF-HARDY LIGNEOUS PLANTS OF THE ORDER 
GERANIA‘CER. 
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 
eee ttom of a wall, if the soil be kept quite dry during that season, and covered with straw. The 
151 
following sorts may, perhaps, be chosen for a trial, in preference to some others : — P. Barringtdnii, 
cucullatum (fig. 150,), macrinthon, megalénthon, calamistratum, quercifdlium, peltdtum, zonale 
(fig. 151.), Bentinckfanwm, inquinans (fg. 152.).
