all cases these are the only localities for the species thus far 

 known in Maine. 



Oxalis filipes Small, has been collected once in Falmouth, 

 Maine, and O. stricta L., in Belgrade, Scarboro, and sev- 

 eral other localities. Psedera qiiinquefolia (L,.) Greene, var. 

 hirsuta (Don.) Render, has recently been detected near Ban- 

 gor, the first station east of the Champlain valley. Of the 

 recent segregates in Viola, three species form interesting 

 additions to the Maine flora; V. Brittoniana Pollard, from 

 Georgetown, its previous northern limit being the vicinity of 

 Concord, Massachusetts; V. Novae- Angliae House, a char- 

 acteristic species of the St. John and upper Penobscot valleys; 

 V. nephrophylla Greene, a species originally described from 

 the Rocky Mountain region, but now known throughout the 

 limestone districts of central and northern Maine. Oenothera 

 pratensis (Small) Robinson, has been until recently confused 

 with CE. fi-iUicosa L. Stations for it are now known along 

 the edges of the salt marshes as far north as Wells. The fol- 

 lowing plants are known in Maine from but a single station: 

 Saniada trifoliata Bicknell, one specimen collected many 

 years ago at Manchester; Hottonia inflata Ell., South Ber- 

 wick; Samohis floribwidus HBK., Winnegance Creek; Teti- 

 crium occidentale Gray, at Orono. 



The Maine material of the genus Rhinanthus has recently 

 undergone much critical study, with the result that three spe- 

 cies are now known to occur within the limits of the State. 

 True R. Crista- Gallic,., is found along the coast from Gaspe 

 southwards ; R. oblongifolius Fernald, from Mt. Katahdin, 

 Mt. Washington, N. H., Mt. Marcy, N. Y., and Table-topped 

 Mt., Gaspe; R. Kyrollae Chabert, in the St. John valley and 

 adjacent Nova Scotia; fourth species, R. stenophyllus (Schur.) 

 Schinz., is to be expected in Eastern Maine. 



Two species of Campanula are also of interest; C. apari- 

 noides Pursh, seems to be rather rare in Maine save in the 

 southern portion, northward its place is taken by C. uliginosa 

 Rydb.
