I have found C. sedoides f. crassicaulis in Ceylon in several specimens from Matara, Dondra Head, and Weligama on the south coast (fig. 47). Almost all correspond well with Agardhs's /. crassi- caulis. Thus the vesicles are, as a rule, always spherical, there are no joints on tli« main axis, and the closely set branchlets stick out in all directions around the main axis. But, on the other hand, the. Fig. 47.—C. sedoides (r. br.) c. ag. /. crassicaulis J. G. AG. (1 X 1). vesicles are sometimes provided with a very short but distinct stalk (fig. 48), and this seems also to be the case with Agardh's own type-specimens, a character again shown in some high-grown crassicaulis forms (in the Herbarium of the R. Riksmuseum in Stockholm) from Torres Strait (Aug. 1846). Also Weber v. Bosse speaks about (loc. cit. p. 388) a Caulerpa from Upola, in which some branchlets are.
