This species is nearest, in size of utricles, to the Juan Fernandez Schizo- 

 codiums described above. The adult utricles, however, have not only a very 

 much thickened galeate lip, but the outer layer of the tip is curiously and 

 distinctively marked, being thrown up into folds, papillae, or warts. The plant, 

 furthermore, is characterized by a complicated repent or decumbent base. It 

 seems to be a very distinct species and the type (and only known) locality is 

 Lobos de Tierra, not far to the south of Payta, Peru,

This seems to be worthy of independent rank and far removed from true 

 C. dichotoiHuni (Huds.) Setchell {C. touie^itosuin (Huds.) Stackh.) of the oceanic 

 shores of Europe. Its utricular dimensions alone are sufficient to clearly dis- 

 tinguish it. Its decided tendency to flatten also removes it from the y>toinen- 

 {osum» complex (as more strictly limited). It was collected at Lobos de Afuera, 

 near the Lobos de Tierra. Peru. 



Codiinn cojitractnvi Kjellm. 



The plant from Melinca, Guiatecas Islands, West Patagonia (about lat. 

 48° S.), referred by SvEDELlUs (Sv. Exp. till. Magellanslander, 3, No. 8: 300, 

 1900) to .CodiujH contractiim Kjellm. » is, at present, not clear in status. It 

 seems unlikely that it can be the veritable species of KjELLMAN (Japanese), 

 although SVEDELIU.S has written that the determination was made under the 

 supervision of Professor KjELLMAX himself. SVEDEUUS had a search made 

 for the alcoholic material on which the reference was made but no trace of it 

 was found. Dried specimens were not prepared. The drawings of utricles 

 made by SvEDELlUS in his studies were kindly loaned by him, but they have 

 not, as yet, proved conclusive. SvEDELIUS (loc. cit.) calls attention to the fact 

 that the upper portions of the original species (Japanese plants) are broadened 

 and somewhat flattened below the axils, which is not so apparent in the South 

 American plants he refers to it. It seems, both from KjELLMAN s figure (Bih. 

 till K. Sv. Vet. Akad. Handl. 23, afd. Ill, No. 11: pi. 2 fig. 12, 1897) and from 

 a specimen of the type collection (!) that the terminal branches are swollen 

 below the dichotomous apices and conspicuously contracted just below the 

 dilations and that this is the conspicuous habit of the species. Until the South 

 American specimens upon which the reference of SvEDELlLS is based become 

 available for study, it seems best to consider the presence of C. coniraclmn 

 Kelm. on the west coast of Sou^h America as doubtful.
