1915] Weatherby,— Two Extensions of Range in Gramineae 71 
precedents. We have now a list of about 200 flowering species that 
extend along the Canadian border across the continent. In the genus 
Viola we may mention V. adunca, V. nephrophylla, V. palustris, V. 
renifolia, and V. Selkirkii. It is not improbable that stations in- 
termediate between eastern Ontario and British Columbia will be 
discovered for V. septentrionalis.— Ezra BRAINERD, Middlebury, 
Vermont. 
Two Exrensions or RANGE IN GRAMINEAE.— During the past 
collecting season, I noted the following grasses somewhat outside 
their recorded ranges: — Bromus Karmu Gray. In low, sandy 
woods in the valley of the Little Androscoggin River, Oxford, Maine. 
Apparently not hitherto reported east of Middlesex County, Mass., 
whence it is recorded, as an introduced plant at Malden, in the 
Flora of the Boston District (RmopoRa, xv. 148). In the same 
patch of woods at Oxford grows Lupinus perennis, also near its 
northwestern limit there. 
Panicum CoMMONSIANUM Ashe. In dry, loose sand at two 
stations, Dennis, Mass. I am indebted to Prof. Hitchcock for 
the determination of these specimens. The species probably occurs 
also in the adjoining town of Harwich, but the plants there were 
collected too late in the season for certain identification. It is 
known from Long Island and from three localities in sand-plain 
regions of Connecticut but, so far as I am aware, has not been 
previously reported from Massachusetts. Both the Dennis stations 
‘were along old and little-used wood-roads. Situations of this general 
character, where original conditions have been altered and the 
soil more or less disturbed, offer favorable ground for the growth of 
certain species of Panicum. P. strictum Pursh (P. depauperatum 
Muhl.) and species of the huachucae alliance often flourish mightily in 
recent clearings or where woods have been burned over. On Cape 
Cod there are many old excavations from which sand for the making 
of cranberry bogs has been taken, and the sides and bottoms of these 
sometimes furnish good Panicum collecting. The only stations for 
P. umbrosum LeConte (P. Ashei Pearson) and P. barbulatum which I 
have seen on the Cape are in such excavations.— C. A. WEATHERBY, 
East Hartford, Connecticut.
