BICKNELL: FERNS AND FLOWERING PLANTS OF NANTUCKET 387 
John W. Harshberger in August, 1915. It had not before been 
known from Nantucket and we must suppose it to be an intro- 
duction more or less recent. 
*MENTHA GLABRATA (Benth.) Rydb. 
Mentha canadensis var. glabrata Benth. 
Collected by Miss Gardner at Wauwinet in full flower July 24, 
1915. Plant evidently bright green, leaves narrow, attenuate at 
base, rather distantly low-serrate, glabrate. On Nantucket 
Mentha canadensis L. shows a marked tendency towards an unusual 
degree of pubescence, and extreme examples even closely approach 
the more northern var. lanata Piper. The glabrate plant is thus 
at contrast with the ordinary Nantucket form in a very marked © 
degree. At Alexandria Bay on the St. Lawrence, where I once met 
with it, it appeared so unlike M. canadensis that I did not at first 
suspect its close relationship. Its unmistakably different and 
pleasanter fragrance seemed especially noteworthy. 
*SOLANUM VILLOsSUM (Mill.) Lam. 
Mrs. Flynn has sent me an excellent specimen of this plant in 
flower and early fruit collected by her in a yard at Milk and Main 
Streets, September 4,1901. The plant is over 6 dm. high, openly 
branched, with thin sinuate-dentate leaves, and is more or less 
villous-pubescent throughout, especially on the younger parts, and 
evidently somewhat viscid; the inflorescence is racemose rather 
than sub-corymbose asin S. peregrinum Bicknell, the calyx lobes 
membranous, only slightly if at all venose, and triangular acute; 
the flowers appear to be somewhat larger than those of S. nigrum L., 
their anthers 1.5-1.75 mm. long on glabrous filaments. It agrees 
closely with many authentic specimens of S. villosum from Colorado 
and Idaho to Washington and California. I am not aware that it 
has ever been reported from New England. 
*ASTER ERICOIDES L. 
In Miss Gardner’s herbarium I found a specimen of this aster 
from Tuckernuck, collected September 14, 1914. It isa somewhat 
pubescent form approaching the var. villosus T. & G. and agreeing 
rather closely with examples from Chappaquiddick Island where, 
as elsewhere on Martha’s Vineyard, it is a scarce plant.
