Ecological and systematic studies of Ecological and systematic studies of the Ceylon species of Caulerpa ecologicalsystem00unse Year: 1906 IHE CEYLON SPECIES OF CAULERPA. 125 root-branches fixed to the scarred rocks ; on the other hand, the vertical axes are few and with ratiier large intervals between them. The result is that the plant becomes firmly fixed, because the rhizome and the system of roots are so strongly developed in comparison with the relatively few and short assimilation branches which they have to keep attached. The vertical axes are slender with close pinnules. These, in regard to their form, may vary a httle, in that they are sometimes quite cylindrical—which is the most common, sometimes more clavate and somewhat flattened laterally. The former kind of branches is the commoner, and if both kinds occur on the same vertical axis the cylindrical ones are to be found at the base, the clavate ones at the top. This form is precisely Grevillb's C. Ictica (H/iRVEY, Ceylon Algae No. 64) according to specimens in J. G. Agardh's Herbarium in Lund (No. 6,744).
