After renewed examination and after having seen a specimen of Gracilaria Blodgettii Harv. it is evident to me that the plant, to which 1 previously have given this name, cannot be referred to this species, but must be regarded as a new species for which 1 propose the name Gr. cylindrical referring to the nearly cy- lindrical thallus, which is only interrup- ted by the narrowings at the base of the branches (Fig. 364). The plant reaches a height of about 22 cm. It is fastened to the substratum by means of a small disc. The main stem, being quite thin at its outgrowth from the disc, soon reaches the normal thickness of the thallus, about I'/s—2 mm and this thickness it keeps through- out. The branches are issued on all sides. The ramification is rather irregular with shorter or longer distance between the branches. These are altogether a replica of the main stem. At their outgrowth from this they are quite thin, but rapidly obtain the normal size of the thallus keeping this through their whole length (often more than 10 cm) to their obtuse apex. The branches are mostly unbranched, but now and then they issue a. Fig. 364. Gracilaria cylindrica nov. spec. Habit of a plant. (About Vs natural size).
