Just after the above remark had been written, Prof. Wille 

 showed me a new work by Setchell, with the title "Algæ novæ 

 et minus cognitæ, 1." (Univ. of Calif. Public. Botany, Vol. 4, 

 No. 14, May, 1912). In it Setchell rearranges four species of 

 Coilodesme found on the west coast of North America. But 

 what he mentions as a new species, Coilodesme amplissima, 

 is in fact nothing but Adenocystis californica Rupr., as may 

 be well understood from the remarks given above. The description 

 of the species by Ruprecht is by no means definitive. The ex- 

 ternal form of the plant is simply inferred by his saying "Die Ab- 

 bildung von Adenocystis Lessoni Bory, Voy. Goq. Tab. II, Fig. % 

 passt so gut auf die californische Pflanze, . . ." This simple remark 

 only leads to uncertainty as regards his species for those who have 

 no opportunity of gaining access to the original specimens. The 

 confusion in the Coilodesme species of the eastern Pacific are 

 naturally difficult to avoid. This confusion is due to Kjellman, 

 who erroneously identified the form in question with Ruprecht's 

 species.

The plant grows multicipitally on a complanated disc-shaped 

 root, which adheres firmly to the surface of the substratum. The 

 frond is simple, cylindrical and hollow; the lower part attenuates
