BICKNELL: FERNS AND FLOWERING PLANTS OF NANTUCKET 375 
to the var. glaucodea Piper, according to Piper’s description 
(Contr. U. S. Nat. Herb. 10: 22. 1906). I am inclined to think 
that our native salt marsh grass commonly referred to F. rubra 
is distinct from the European plant and should stand as Festuca 
glabra Spreng. 
*FESTUCA ELATIOR L. 
F. arundinacea Schreb. 
Very typical examples of the tall fescue grass were collected 
June 18, 1910, by a fence along the railroad on Washington Street, 
the larger panicles 47 cm. in length, the spikes 15-17 mm. long, 
and leaves as broad as 1.5 cm. Also found on Easton Street, 
June 3, 1911. 
Although the distinction between the tall fescue and the 
meadow fescue (F. pratensis Huds.) is not now commonly recog- 
nized, their differential characters are too pronounced to be justly 
disregarded. These differences are well brought out in the de- 
scriptions of both species in the first edition of Gray’s Manual. 
BROMUS HORDACEUS L. 
Forms having the spikelets glabrous or nearly so are doubtless 
to be referred to the var. leptostachys (Pers.) Beck (var. glabrescens 
[Coss.] Shear). It is abundant by roadsides near the railroad in 
the suburbs of the town. 
BROMUS COMMUTATUS Schrad. 
Brant Point Road; above the Cliff; Island View Farm; coming 
into flower early in June. Bromus racemosus L., included earlier 
in this list, should doubtless be referred to a small form of B. 
commutatus, if the two are held to be distinct. 
*ScIRPUS OLNEYI Gray. 
Sparingly in a salt marsh along a thicket near Abram’s Point, 
not yet fully mature June 2, 1909. 
*SCIRPUS NOVAE-ANGLIAE Britton. 
Abundant along the inlet to Coskaty Pond, June 12, I9II; a 
well-established colony at Squam Pond varying in extent in dif- 
ferent years; spikes appearing June 10, 1911, not yet fully devel- 
oped June 20, 1910; in full flower July 4, 1912. Also collected in 
Squam by Miss Gardner, September 2, 1913, then in mature fruit.
