more dense, some of branches are set free. The disposition of branches is 

 not strictly distichous, having five or more branches or branchlets often 

 arising near to one another. They appear at the beginning like a minute 

 tooth or like a'spinose prominence. They are almost cylindrical (300-350 ji 

 thick in subcylindrical portion) or slightly compressed and are sometimes more 

 flattened and widened in those of the higher order. Eamuii attain the 

 length of 1-3 mm. Cystocarps and tetraspores have exactly the charact- 

 ers of the genus. Colour red. Substance cartilaginous. 



Remarks : At a first glance, the present plant is often erroneously 

 taken for Endocladia complanata Earv., with which it is often found 

 growing together ; but the difference is at once manifest from the mode of 

 ramification, structure of frond, &c. On the other hand, it shows in its 

 external apperence some resemblances to Gelidium divaricatum JJartens. 

 The latter species, however, differs in forming a dwarf, jlulvinate mass, 

 having no creeping and rooting segment-. 



Feyssormelia can lifer a Sp. no v. Fig. 26-30. 



Diagnosis : Frond leathery, flabelliform or reniform, either undivided 

 or with similarly shaped and slightly imbricating lobes, covered with buffy- 

 colored hairs on the under surface, furnished with a thick stalk-like bundle 

 of root-fibres, perfectly flat at margin, and marked with concentric lines. 

 Fruits of both kinds forming irregularly roundish patches over the upper 

 surface. 



Hab. On rocks or roots of some larger algae beneath the tide marks. 

 Sagami, Boshu. 



Descrijitiun : Frond fixed to the substratum by a thick stalk-like 

 bundle of root-fibres, which mostly arises near the base of frond, but some- 

 times a few are produced here and there, and even near the margin. 

 Thus, the plant does not closely adhere to the substratum by its whole 

 under surface but is elevated on the stalk-like support. Frond 3-4 cm. 

 long and nearly as broad in the widest part, cuneate at the base, becoming 

 flabelliform as the frond widens ; sometimes undivided and entire, but often 

 vertically cloven. And each lobe, after growth is renewed, becomes flabel- 

 liform like the original frond, being slightly imbricated. The margin along 

 the curved, upper edge is perfectly flat, but folded back when dried. The
