﻿34 Bicknell: Ferns and flowering plants of Nantucket 



MENYANTHACEAE 

 Menyanthes trifoliata L. 



Mrs. Owen's catalogue bears record that this plant was found 

 in Maxcy's Pond in 1853. It has remained there to this day in 

 a secluded corner of the pond where, in 1909, it spread over an 

 area not less than thirty yards in greater extent. I know of it 

 also at three other stations on the island: in Shawaukemmo 

 meadow; in a wet bog on Little Neck, where there is much of it, 

 and in Round O Swamp, a circular bog perhaps one hundred 

 yards across, set in the open on the western side of the island. 

 So abundant is it here that, in early June, before becoming hidden 

 by taller growing plants, its crowded leaves overspread the swamp 

 in one unbroken level of dark bluish green, made more striking 

 to the eye by a wide encircling rim of golden green from the 

 budding leafage of the investing shrubbery. Here on June I, 

 1909, it appeared to have passed entirely out of bloom until my 

 field glass revealed a few plants in the very middle of the swamp 

 still in full flower. The following year three weeks later in the 

 season it was completely screened from view by a taller growth 

 of Calamagrostis and Decodon. Found at one station on Martha's 

 Vineyard. 

 Nymphoides lacunosum (Vent.) Kuntze. 



Lymnanthemum lacunosum Griseb. 



In many of the fresh water ponds. Just in flower June 15, 

 1908, June 27, 1910; in full flower July 6, 1912, on the eastern 

 side of the island, not yet quite in flower on the western side 

 July 10. Occurs on Tuckernuck. 



APOCYNACEAE 

 * Vinca minor L. 



Sparingly escaped from cultivation in and near the town. 

 In full flower June 4, 1911. 

 Apocynum androsaemifolium L. 



Occurs sparingly on the eastern side of the island in Pocomo 

 and Squam and near Siasconset. In full flower near Wawinet 

 July 8, 1912. Corolla brightly pink tinged, the largest 6.5 mm. 

 long, spreading 8 mm.
