O. strumifer. Brid. “This is again restored to the rank of a species, as it differs from O. polycarpus (Dicranum) in the caps. being more or less cernuous, constantly strumose at base, with a compound annulus, and in the leaves having papillæ only on the upper surface.” [Dr. Braithwaite, Jour. Bot. VIII. 228.]
84. Dicranum heteromallum. δ. sericeum.
Add as a synonym, Dicranodontium sericeum. Schp.
85. D. Starkii. β. molle =
D. arcticum. Schp. Its general appearance better distinguishes it from D. Starkii than its microscopical characters. It is quite erect, growing in large loose patches, stems 3–4in., elastic, very robust; foliage of a fine purplish brown colour; leaf wider below, and more suddenly contracted upwards, with a thinner nerve; fruits earlier. [Hunt. l. c. p. 321.]

Add as synonyms Dicranodontium aristatum. Schp. D. asperulum. Mitt.
96. D. palustre. Brid. Dr. Braithwaite points out in Grevillea I., 109, that La Pylaie’s specimens of this moss (Bridel Bryol. Univ. I. 814) belong to Campylopus flexuosus, as shewn by De Notaris in his Epil. Bryol. Ital.; and that hence the name D. Bonjeanii, De Not. is to be preferred. The synonymy would then stand:—
