FLOWERING PLANTS OF NANTUCKET 373 
Arisaema pusillum (Peck) Nash. On Nantucket extremes of 
this plant are at marked contrast. At Watt’s Run and in Trot’s 
Swamp the smallest and most delicate form, with narrow black- 
purple spathes and slender linear spadix, may be seen growing near 
by much larger examples having broader, striped, or even wholly 
green spathes and with the spadix sometimes slightly clavate. 
In some plants the spathe is fluted or ribbed on the inner as well 
as the outer side. Observed in flower from June 1 to July 4. 
Lemna minor L. Sachacha Pond; Shawkemo; Capaum Pond. 
Lemna trisulca L. Choking the ditches in meadows north of 
the town, and in great masses floating and submerged in No- 
Bottom Pond. 
Tradescantia virginiana L. Scattered through a sandy lot on 
the north side of the town; also a large tuft in a grassy opening 
in pine woods south of the Fair grounds, June, 1910. 
Juncus balticus Willd. At several localities in Shawkemo 
growing in abundance along the borders of fresh water bogs near 
the shore as well as in brackish soil. 
Lilium philadelphicum L. Leaves commonly very narrow and 
often somewhat scattered, suggesting an approach to L. umbel- 
latum Pursh; but the capsules, although often attenuate at base, 
are very variable in size and form and are mostly obovoid or 
obovoid-oblong. 
Vagnera stellata (L.) Morong. Additional localities are Trot’s 
swamp, where it is locally common, and Thorn lot, Shawkemo. 
Small plants growing on the open plains near the South Shore 
have the later leaves perfectly glabrous beneath. 
Polygonatum biflorum (Walt.) Ell. Salomonia biflora Farwell. 
To be regarded as not uncommon rather than scarce or local, 
but not met with on the western side of the island. 
Medeola virginiana L. Restricted to the same parts of the 
island as the preceding and mainly to the same thickets, in some 
of which, especially in Shawkemo, it is a frequent plant. 
Smilax herbacea L. Not infrequent, extending from the locali- 
ties previously reported into Pocomo.
