George Town, V. D. L., R. Gunn, Esq., n. 1295.—Two 
imperfect and half decomposed specimens of a fine Chylo- 
cladia, probably new, but too closely allied to C. articulata 
for me to venture to describe it without more perfect speci- 
mens. The substance is far more gelatinous than in C. 4" 
ticulata, and the size, unless we compare it with the gigantic 
state figured by Turner, is much greater. The length of the 
lowermost constrictions is, in one specimen, an inch and - : 
the other 14 inches. It appears to decompose rapidly ? 
fresh water, throwing off its ultimate ramuli as a Stars" 
does its rays. The frond is irregularly dichotomous, with 
very patent axils, constricted at the branching; the upper 
divisions umbellate, 4-5 new branches springing from boos 
top of an old one, and these from their apices giving birth 
to saccate clavate ramuli. ds
