This little plant grows epiphytically upon larger algae, e. g. Turbinaria and Zonaria. It is fastened to the host-plant by means of a small roundish disc. In the specimens examined by me the disc was about 400// in diameter. From the surface of this disc the erect filaments arise; at their base, where they are attached to the disc, a node is always present. As the specimens showed some differ- ences according to their growing upon Turbinaria ov Zonaria I wish to describe them separately and begin with those upon Turbinaria (Fig. 181). This was growing in a very exposed place at Judith Fancy on the north side of St. Croix and on account of this the specimens of Jania had also a Fig. 181. Jania pumila Lamx.

Some of them consist of a single joint which on its top bears a conceptacle, others are longer, a few times dichotomously divided, ending in conceptacles, if they are not throughout vegetative. In the basal part of the filaments the vegetative joints are mostly oblong-cuneate with broadly rounded top and very atten- uated base, in the upper part nearly cyUndrical, tapering some- what to both ends. The first mentioned joints are about 200// long, about 150/i broad at their upper end and 70/^ at their base, but much larger ones occur; the more cylindrical joints in.
