252 Proceedings of the Club 



Dr. Britton called attention to the supposed variants of R. hirta 

 with parti-colored rays, as suggested by plants from near Phila- 

 delphia and from Staten Island. 



Dr. Britton presented the subject of the relationship of our 

 woodland species of Circaea, C. Lutetiana being the representative 

 near New York City, and extending widely around the world. 

 The characteristic bristles of the fruit fail to appear in a remarkable 

 specimen from Ohio which was exhibited. C. intermedia of Cen- 

 tral Europe was also discussed in its relations to the foregoing.

Dr. Britton exhibited a series of specimens of Antennaria 

 neodioica Greene, a species which seems to be easily distinguished 

 from the others of eastern North America by its spatulate basal 

 leaves, distinctly mucronate, tapering rather abruptly from well 

 above the middle into a long narrow base, which, however, can 

 scarcely be called a petiole. He showed specimens of the plant 

 collected in company with Professor Greene at Bushkill, Pa., on 

 the Club's Field Meeting, May 30, 1897, at which time Professor 

 Greene first insisted on its specific difference from A. plantaginifolia 

 with which it grew. The series included authentic specimens of 

 Antennaria rupicola Fernald, which differs from the typical speci- 

 mens of A. neodioica only in the yellowish involucre, and slightly 

 less abruptly tapering leaves, collected by Mr. Fernald at Island 

 Falls, Aroostook Co., Maine, also specimens of A. neodioica at- 

 tenuata Fernald, and of A. neodioica grandis Fernald, discussing 

 their relationships with previously described species. 



Dr. Rusby referred to the similar variability of Andean species 

 of Gnaphalium as seen by himself and other botanists in Bolivia. 



Dr. Howe discussed the relationship of Riccia Beyrichiana, 

 the hepatic which he had considered to be probably identical with 

 one discovered by Mr. R. M. Harper near Athens, Georgia, last 

 summer. The loan of the type-specimen from Vienna now shows 

 that the two are wholly distinct, Mr. Harper's plant representin 

 a new species, described in the Bulletin for March. Riccia Bey- 

 richiana seems therefore to be still known only from the origi- 

 nal collection of 1833.
