more ovate leaves, by the indentations between the teeth of 

 the leaves and by the more compound stipules. 



2. C. jugalifolius, Tayl.; caule laxe implexo, procumbente, 

 subsimplici ; foliis subimbricatis, patentibus, ex lata basi 

 triangulari-ovatis, retusis, biciliatis, caeterum integerrimis, 

 cum stipulis minoribus 4-5-ciliato-partitis connatis. 



Hab. Guyana. Richard, Hook. Herb. 



Dusky olive-green. Stems above an inch long, one tenth 

 of an inch wide, rather straight. Stipules scarcely wider 

 than the stems; their cilia elongated, articulated. This 

 differs from J. coalita, Hook, by the longer and more patent 

 leaves, by the more inconsiderable stipules, which are more 

 deeply divided. 



3. C. gibbosus, Tayl.; caule implexo, procumbente, ramis 

 erectiusculis, incrassatis ; foliis imbricatis, patentibus, con- 

 cavis, oblongis, acutiusculis, integerrimis, apice recurvis, 

 stipulae quadrato-rotundatae, emarginato-bifidae, hie illic 

 spinoso-dentatae conjunctis ; calyce terminali, ovato-aeu- 

 minato, inflato, gibbo. 



Hab. Martinique; Richard, Hook. Herb. 



Purplish brown. Stems 2-3 inches long, shoots flattened. 

 Stipules large, joined by a very narrow isthmus on each side 

 to the leaves. Calyces larger, subtrigonal, pale, the mouth 

 small, subdentate. The leaves are far longer and more 

 closely imbricated and the stipules longer than in C. grandi- 

 folius, Tayl. 



4. C. Drummondiiy Tayl.; caule implexo, repente, subramoso, 

 gemmifero, adscendente, attenuato; foliis erecto-patentibus, 

 oblongis, bifidis, caeterum integerrimis, stipulee ovatse, 

 acutae, subintegerrimae utrinque connatis; calyce sessili, 

 ventrali, basi laciniato-squamoso, oblongo, inflato, ore 

 bifido, acuto, subcompresso.
