CIS'SUS,/. [from y.Kraos, ivy.] In botany, a genus of 
the clafs tetrandria, order monogynia, natural order of 
hederaceae. The generic charaSlers are—Calyx: invo¬ 
lucre many leaved, very fmall. Perianthium: one-leafed, 
flat, fhort, four-cornered. Corolla : petals four, concave. 
Neftary a rim furrounding the germ. Stamina : filaments 
four, the length of the corolla, inferted into the nectary ; 
antherse roundifli. Piftillum : germ roundifli, obtufely 
four-cornered, retufe. Style filiform, the length of the 
ftamens. Stigma fimple, acute. Perianthium : berry 
round, Alining, umbilicate. Seed: a roundifh ftone. 
This genus has a great affinity with hedera ; the fruit 
is a berry, and it has one-fifth lefs in the parts of the 
flower : alfo with vitis.— EJj'cntial CharaSler. Berry one- 
leeded, furrounded by the calyx, and four-parted corolla. 
Species, i. Cilfus vitiginea, or vine-leaved ciflus : leaves 
cordate, with about five lobes, tormentofe. Linnaeus ob- 
ferves, that this fpecies of ciflus has the appearance of a 
vine ; but differs in the calyx, corolla, number of ftamens, 
and in having a llyle. The Item is tormentofe: the 
branches villole, hoary at top, and fubquadrangular. 
Leaves alternate, two inches long, entire, fometimes 
flightly angular towards the tip, three-lobed or obfcurely 
five-lobed, (like thofe of mallow,) nerved and veined, 
more villofe beneath, bluntly and unequally toothed, the 
middle lobe larger than the others ; the yOunger ones 
tomentofe on both Tides : they are on unguicular petioles. 
Flowers hoary, molt of them deciduous: fruitful pedicels 
commonly in pairs and divaricating. Berries pear-lhaped, 
the fize of peafe, of a blueifh glaucous colour. Native of 
the Eaft-Indies; introduced here about the year 177a. 
2. Ciflus repanda : leaves cordate, entire or fublobed, 
repand, fmootli on both fides. The branches of this are 
round, flexuofe, jointed, tomentofe, but becoming fmooth 
by age. Leaves petioled, from two to three inches in 
length, and llill more in breadth, of a more firm texture 
than in the other fpecies, nerved and veined, thole which are 
more advanced fmooth on both fides, but the younger 
ones villofe ; the notches finifh in a minute dagger point: 
they are ve ry blunt, but fometimes have a fliort blunt 
point at the end. Native of the Eaft-Indies. 
3. Ciflus latifolia : leaves cordate-ovate villofe acumi¬ 
nate fetaceons-ferrate, branches four-cornered. Branches 
jointed, woody, as are alfo the petioles and peduncles, 
ferruginous-tomentofe, elpecially at fop, by age becom¬ 
ing fmooth at bottom. Native of the Eaft-Indies. 
4. Ciflus cordifolia: leaves cordate quite entire. 
Branches fimple, knotty. Native of South-America. 
5. Ciflus rotundifolia: leaves cordate-roundilh, ferrate. 
Native of Arabia. 
6 . Ciflus ficyoides: leaves fubcordate, naked, briftly- 
ferrate, branchiets round. Native of Jamaica, in walte 
places, by walls, and on pocks : Jacquin flays, in all the. 
Caribbee iflands, and the neighbouring continent, dif¬ 
fering in habit according to the lituation in which it 
grows. The berries of this and fome other forts are 
fometimes eaten by the natives and negroes, but they are 
chiefly food for birds. 
7. Ciflus quadrangularis : leaves cordate, flefliy, fer¬ 
rate-toothed, item four-cornered, fomewhat fwelling. 
Native of Arabia and the Eaft-Indies; found alfo near 
Mozambique in Africa, by Loureiro. 
8. Cilfus acida, or three-leaved cilfus : leaves ternate, 
obovate, iinoo.th, fleftiy-gaftied : native of Jamaica, in 
woods near the coalt. The whole of it is acid. Culti¬ 
vated, as we learn from Plukenet, in 1692, at the royal 
garden, Hampton Court. ;

9. Cilfus trifoliata : leaves ternate, roundifli, Iiirfute, 
with a few teeth, branches angular and membranaceous. 
Native of the Weft-Indies, climbing high above the 
branches of the trees, in the hedges, upon the mountains. 
10. Cilfus crenata : leaves ternate, leaflets roundifli, cre- 
nate. Native of the Eaft-Indies. 
11. Ciflus carnofa : leaves ternate, ovate, obtiife, fer¬ 
rate, fmooth ; branches and petioles round. The whole 
plant fmooth ; branches ftfliated, round. Native of the 
Eaft-Indies. 
12. Ciflus obovafa: leaves ternate; leaflets obovate, 
quite entire, fmooth. Native of America. 
13. Ciflus pedata: leaves pedate; leaflets, lanceolate, 
ferrate, tomentofe underneath. Branches tomentofe, 
hoary. Native of the Eaft-Indies. 
14. Ciflus heptaphylia : leaves in fevens, ferrate, hif- 
pid. This is a" farmentofe fcanderit flirub ; branches pu- 
befcent; leaves alternate, petioled, compofed of a pair, 
a ternate, and a Angle leaflet larger than the reft, a fecond 
time petioled. Koenig lent it front Calcutta. 
15. Ciflus umbellata : leaves ovate, quite entire, 
flowers umbelled; Item fhrubby, twining, long, branch¬ 
ed : leaves oppofite, fmooth ; flowers, white, in compound 
terminating umbels. Nati ve of China about Canton. 
Propagation and Culture. The plants are preferved i» 
fome of the European gardens, more for the fake of 
variety, than for ule or beauty, as they rarely produce 
either fruit or flowers in moderate climates. They are 
propagated either by laying their flexible branches down 
in pots of earth, where they will put out roots in four or 
five months, or by planting cuttings in pots filled with 
light earth, which Ihould be plunged into a moderate hot¬ 
bed of tanners bark, covering the pots clofely with hand- 
glafles to exclude the outer air: the cuttings muft be 
frequently refreflied with water, but not too much given 
at each time. When thefe or the layers are well rooted,, 
they fliould be carefully taken up, and each planted in a 
fmall pot filled with light earth, and plunged into the 
liot-bed of tan, where they fliould. conftantly remain, 
being too tender to thrive in England, but with this care. 
Therefore they fliould be fliifted into larger pots when it. 
is neceflary, and their branches muft be fupported with 
ftakes, to prevent them from trailing over the neighbour¬ 
ing plants ; and in warm,weather the plants fliotiid have 
free air admitted to them daily. With this treatment 
they will thrive very well.
