South of the Lakes no additional species are known, unless an 

 unverified report of Adiantinn pcdatinii L. should prove correct. 

 The Maiden-hair is one of the greatest rarities in Nova Scotia, 

 hence the scepticism. The most promising district in the south- 

 east is believed to be still unexplored by a botanist. 



Woodzuardia Virginica (L.) J. E. Smith, Asplcniiim TricJio- 

 luanes L., Dryopteris fragrans (L.) Schott, D. Boottii (Tuckerm.) 

 Underw., and Woodsia ohtiisa (Spreng.) Torn, all found in Nova 

 Scotia, though rare, have not yet been collected in Cape Breton, 

 in spite of the fact that two of them reach the western side of 

 the Strait.

THE TYPE-LOCALITY OF ARENARIA BREVIFOLL\ 



P)Y Roland M. Harper 



Arenaria brcvifolia,^ " the rarest of our eastern American 

 Arenarias," f was for many years known only from the granite 

 region of Middle Georgia, particularly on and around Stone 

 Mountain, where it was collected by Canby in 1869 and by sev- 

 eral other botanists in later years. (It has since been found in 

 Rowan County, North Carolina, by Heller and Small, in Lee 

 County, Alabama, by Professor ILirlc, and in DcKalb Count)', 

 Alabama, by Dr. Mohr. At the last-named station it grew on 

 Carboniferous sandstone, but at all the others its habitat is on gran- 

 ite.) It was natural to suppose, therefore, that the original speci- 

 mens were collected by Nuttall somewhere in Middle Georgia, 

 though not on Stone Mountain, which scciils to have been 

 unknown in Nuttall's time.
