. Ecological and systematic studies of the Ceylon species of Caulerpa . Fig. 14.—C. davifera (turn.) c. ag. f. remota n. /. (1 x 1). As has been mentioned above, C. davifera forms are, as a rule, never met with in other places than in the uppermost part of the littoral region. Sometimes, however, one can find in deeper water a Gaulerpa form whicla apparently is closely related to davifera. Fig. 14 shows such a one, which I found at Galle in a dark deep pool growing on another alga. It differs in that the vertical axis system has been elongated and the branchlets or pinnules have been separated
. Ecological and systematic studies of the Ceylon species of Caulerpa . Fig. 14.—C. davifera (turn.) c. ag. f. remota n. /. (1 x 1). As has been mentioned above, C. davifera forms are, as a rule, never met with in other places than in the uppermost part of the littoral region. Sometimes, however, one can find in deeper water a Gaulerpa form whicla apparently is closely related to davifera. Fig. 14 shows such a one, which I found at Galle in a dark deep pool growing on another alga. It differs in that the vertical axis system has been elongated and the branchlets or pinnules have been separated, and especially in that the stalks of the branchlets are often considerably longer than the spherical vesicles, wliile the main axis itself has been also considerably elongated. The whole plant gets through this, a habit wliich reminds one of G. Lamourouxii, at least its forms which have always cylindrical main axis. The original /. Lamourouxii, as it was described by Turner—and according to him by C. A. and J. G. Agardh—had only cylindrical axis. But, owing to the occurrence of transition forms to such forms as have flat axis, Weber v. BossE has brought together all these forms under var. jLawoMrottm,\vhich thereby has received a very extended sense. 49-06
