374 BICKNELL: FERNS AND FLOWERING PLANTS OF NANTUCKET 
forms appearing to intergrade variously with P. meridionale, but 
characteristic examples stand well apart. 
A series of specimens of all three species has been verified by 
Professor Hitchcock and Mrs. Chase. 
*PANICUM AUBURNAE Ashe. 
Collected in Squam, at Surfside and in the pine barrens. 
Specimens have been determined by Professor Hitchcock and Mrs. 
Chase. Compared with a series from Long Island the Nantucket 
plant is less copiously velvety-villous, the nodes not so conspicu- 
ously white bearded and the culms less elongate and declined. 
Professor Hitchcock writes me that these Nantucket and Long 
Island specimens are the first he has seen from the coastal region 
north of Virginia. Certain less typical examples from Nantucket 
seem to approach P. albemarlense. 
*PANICUM IMPLICATUM Scribn. 
In low grounds, apparently scarce. Little Neck, June 22, 
1910; Thorn lot, June 17, 1910. 
PANICUM HUACHUCAE Ashe. 
The var. sylvicola Hitche. & Chase, of a lax and slender form, 
was collected on a shaded bank in Squam, June 8, 1912. 
*PANICUM SCOPARIUM Lam. 
Collected by Miss Grace Brown Gardner in Polpis, August 24, 
1915; excellent specimens are preserved in Miss Gardner’s her- 
barium. A most interesting addition to the Nantucket flora, 
connecting the Martha’s Vineyard and Cape Cod stations where 
alone this southern grass was previously known in New England. 
*ARRHENATHERUM ELATIUS (L.) Beauv. 
Sparingly in a field below the Cliff, June 15, 1910, and in Made- 
quet, far from any cultivated ground, June £7; Tt; 
FESTUCA OVINA L. 
Examples of the var. hispidula Hack., having the lemmas rather 
densely hirsute, are occasionally met with in and near the town. 
FESTUCA RUBRA L. 
Not infrequent examples, doubtless introduced, differ from the 
native plant by their blue-glaucous coloring and stiffer leaves, as 
well as in other less obvious characters, and appear to be referable
