CISSA'MFELOS. Pareira Brava Eoot. 

 (From kissos, ivy, and ampelos, a vine; 

 creeps like ivy, and flowers like the vine, 

 on long, hairy racemes. Nat. ord., Meni- 

 spermads [Menispermacese]. Linn., 22- 

 Dicecia 13-Polyandria.) 



Stove twiners. The species from South Africa 

 will do in a warm greenhouse: cuttings of small 

 side-shoots, rather firm, in sand, under a bell- 

 giass, and in bottom-heat ; loam and peat. 

 Summer temp., 60 to 80 ; winter, 45 to 55. 

 C. Caape'ba (Caapeba). 4. Green. July. S. 

 Amer. 1733.

Ci'ssus. (From Jcissos, ivy ; in reference 

 to their scrambling habit. Nat. ord., 

 Vineworts [Vitaceae]. Linn., k-Tetran- 

 dria 1-Monogynia.) 



A genus of stove and greenhouse climbers, 

 having no pretensions to beauty. We introduce 

 it in order to remark, that with the exception of 

 the grape-vine, the plants of this order are singu- 

 larly deficient in use or beauty. The species 

 require the same treatment as Cissampelos. 

 C. di'scolor (two -coloured). Greenish white. 

 September. Java. 



CISTERNS for the accumulation of rain- 

 water should be formed in connexion 

 with the gutters of the various buildings 

 in the gardens ; for no water is equal to 

 it for the artificial supply of moisture to 

 plants. 



CI'STUS. Rock Rose. (From kute, a 

 box; in reference to the form of the seed- 

 vessel. Nat. ord., Rock Hose [Cistacesej. 

 Linn., 1%-Icosandria 1-Monogynia.) 



C. ladani'ferus and C. LtfAon produce gum la- 

 danum. Seeds sown in April ; if under glass, so 

 much the better; layers after the plauts nave
