1923] Evans, — Notes on New England Hepaticae, — XVII 75 



and N. rupestris (Nees) Schiffn., have been reported from New Eng- 

 land. 1 This genus should be included in the genus Grimaldia Raddi, 

 and the New England species should be known as G. jrilosa (Hornem.) 

 Lindb. and G. rupestris (Nees) Lindenb. 2 



In the present series of Notes the nomenclature of Fossombronia 

 brasiliensis is considered, Bazzania denudata is recognized as a valid 

 species and compared with the closely related B. tricrenata, certain 

 species recently segregated from Scapania nemorosa are discussed, 

 and a species of Lejeunea is reported for the first time from New 

 England. In conclusion a few additions to local state floras are 

 reported and a revised census of New England Hepaticae is given. 



1. Fossombronia brasiliensis Steph. Mem. Herb. Boissier 16: 

 28. [Sp.Hepat.l: 382.] 1900. F. angulosa Aust. Hep. Bor.-Amer. 119. 

 1873 (not Raddi). F. salvia Lindb. Acta Soc. Sci. Fenn. 10: 583. 

 1875 (nomen subnudum); Evans, Rhodora 3: 9. 1901. In the place 

 last cited F. salina was first definitely reported from Connecticut and 

 from New England. A few years ago 3 a number of additional stations 

 from a wide range of territory were recorded, extending the known 

 distribution of the species into the West Indies. At the same time 

 the very close relationship between F. salina and F. brasiliensis was 

 emphasized, and it was pointed out that the only important difference 

 between them (according to the published descriptions) was in the 

 inflorescence, F. salina being monoicous, while F. brasiliensis was 

 said to be dioicous. It was further pointed out that the name F. 

 brasiliensis, on account of Lindberg's inadequate publication of F. 

 salina, would have to be maintained, if it should ever be proved that 

 Stephani 's plant was really monoicous and that the two species were 

 therefore synonymous. As a matter of fact Schiffner 4 had already 

 demonstrated a monoicous inflorescence in F. brasiliensis, stating 

 that the antheridia and archegonia were irregularly mixed together 

 on the upper surface of the stem, and on the basis of his account the 

 reduction of F. salina to synonymy would have been justified. In 

 order to be quite certain of this reduction, however, the writer has 

 examined three Brazilian specimens of F. brasiliensis from the Boissier 

 Herbarium at Geneva, kindly sent for study by Professor Chodat.
