Professor Bailey is most appropriate, as the species is the parent of 
some of our best garden varieties. 
RUBUS NIGROBACCUS X VILLOSUS, Bailey. This hybrid Professor Bai- 
ley finds common in Central New York, and he has so named speci- 
mens from a large colony covering a quarter of an acre in Weybridge, 
Vermont. It has been found in four other towns in western Vermont. 
We find it difficult to accept this disposition of our Vermont plant, 
which has more slender bristles, and wider, more glabrous and more 
sharply toothed leaflets than are found in either of the alleged parents. 
The botanical status of this plant requires further investigation. 
RuBus CUNEIFOLIUs, Pursh, with leaves whitish pubescent beneath, 
is a southern species that barely enters New England in southern Con- 
necticut. Specimens seen were from Stratford, East Haven, Killing- 
worth and Milford. 
Kuntz sETOsUs, Bigelow (Florula Bostoniensis, 1824). This 
plant seems to be not rare in the vicinity of Boston, but it has strangely 
failed of recognition in any edition of the Gray Manual. The stems 
are usually erect; but trailing forms are not infrequent even in the 
same colony. It varies also greatly in the width of the leaflet and in 
the abundance of its bristles.  Wide-leaved, prostrate forms are easily 
mistaken for Rudus hispidus. The species appears to be widely dis- 
tributed in New England. 
There remain to be noticed, briefly, our four species of trailing 
blackberries, or dewberries. 
RUBUS vILLOSUS, Ait. As noted above, this name must hereafter 
be applied to what for over-a century has been incorrectly passing as 
R. canadensis. lt is abundant in the lowlands of New England, in 
sterile soil; but rare in the mountains and in Maine, north of the coast. 
The species, though still a variable one, has been much simplified by 
the Segregation of the two following. 
Rupus invisus, Bailey, is a plant every way larger than A. villosus. 
Specimens have been seen from Connecticut, Massachusetts and Maine. 
The Maine plant, collected by Mr. Fernald in Foxcroft, August 31, 
1897, is more robust than the types from Ithaca, N. Y., which, through 
the kindness of Professor Bailey, I have been permitted to examine, 
has more oval and more sharply toothed leaflets, and may be deserving 
of varietal distinction. . 
Rursus Estro, Tratt., has been identified by Professor Bailey 
with the Æ. ziZosus var. humifusus of Torrey. With its slender stem
