Coelarthrum Albertisii (Piccone) Borgs. A, part of a plant (about natural size); B, part of a female plant (about 2:1); C, transverse section showing the diaphragm between the joints (10:1). As mentioned in my former paper this plant was at first found at the Canary Isles by Piccone and described by him as Chylocladia Albertisii. Referring to my above quoted paper with regard to my reasons for considering this plant a representative of a new genus, I shall here restrict myself to a short description of the plant. Coelarthrum Albertisii forms small bushes about 4—5 cm high. The thallus is nearly terete, articulate, hollow, repeatedly dichotomously ramified (Fig. 389 A). The joints are largest in the basal part, in my specimens oblong obovate of shape, about 1 cm long and V2 cm broad; upwards the joints become gradually smaller and nearly spherical. Between the joints diaphragms are present dividing the cavity in the interior into as many compart- ments as there are joints (Fig. 389 C, 390 A). The membrane consists of a layer of rather large cells oblong— rectangular when seen from the surface (Fig. 390 Z), £"), more roundish-quadrangular in transverse section (Fig. 390 A, B, C.).
