ET INSULARUM MARIS PACIFICT. 297 



Ch. Hydropitys var. flaccida, A. Br. in lit. 

 /S. Gaudichaudii, verticillis remotissirais ; aculeis minimis inconspicuis ; 



foliorum articulis 4 ; seminibus solitariis, fasciis 9. 



Ch. fibrosa, Ag. Syst. Alg. p. 129. 



The var. a. was found near Madras by Br. Wight (No. 133 inherb. 

 Hook.) ; /3 in the Marian Islands, by Gaudicliaud (herb. Agardh). 



Ch. flaccida is very nearly allied to the subséquent species, differing, 

 however, by the larger and less contorted seeds with a yellow-brown 

 nut. The naked (uncovered and therefore not striated) leaves are of 

 less importance, Ch. Hydropitys varying also sometimes with naked 



leaves. 



** gymnopodes. 



8. Ch. Hydropitys, monoica, subflexilis et subdiaphana, caule tenui cor- 



ticato, aculeis raris sparsis conicis parum elongatis ; verticillorum 



foliis 10-12, articulis 5-7, primo (sequentibus sequilongo) semper 



ecorticato, sequentium uno vel pluribus corticatis, ultimo breviore 



attenuato foliola geniculi supremi paulatim superante ; foliolis in 



omnibus foliorum geniculis verticillatis, longitudine subsequalibus, 



quam semina subduplo longioribus ; stipulis duplici foliorum numéro, 



longitudine foliolorum, coronam simplicem conspicuam subpatulam 



formantibus ; seminibus solitaris perminutis, coronula brevi obtusa, 



nucleo atro, fasciis 11-13.

On the coast of Coromandel in company with Ch. Ceylonica Willd. 

 {Bélanger in 1826-28 var. 6.) ; Jenkins in Assam (herb. Hook., var. 

 a. and passing into var. b.) ; Busna (herb. Hook. a. and c. mixt). 



One of the prettiest species of the genus, which seems to be equally 

 fréquent in the East Indies and South America. The first spécimens 

 which I received from the East Indies by Bellanger were so exceed- 

 ingly small, in comparison with those from Surinam and the Brazils, 

 that I was led to distinguish them as a particular species ; but the 

 rich séries of this species, in Sir W. Hooker's herbarium, convinced me
