﻿Bicknell: Ferns and flowering plants of Nantucket 



A form collected in Polpis, September 17, 1907, growing on 

 Solidago and Boehmeria, has diverging styles becoming 3-4 mm. 

 in length, and stamens nearly as long as the lobes of the corolla; 

 the scales of the corolla are parted and cleft into a sparse fringe 

 and the depressed-subglobose capsule is not at all umbonate but, 

 on the contrary, definitely flattened at the top. 



BORAGINACEAE 



* Lappula Lappula (L.) Karst. 



Waste yard on North Water Street, June 17, 1910, a single 

 large plant just in flower; Surfside, July 4, 1912, a number of 

 plants in full flower about an abandoned chicken paddock. 



* Amsinckia intermedla F. & M. 



A number of plants in scattered growth with the preceding 

 near Surfside, in full flower and fruit July 4, 1912. Plants erect, 

 becoming 6 dm. high with flowering spikes 2 dm. long; corolla 

 1.25 cm. long, spreading 7 mm., orange yellow, reddened in the 

 throat. 

 Pneumaria maritima (L.) Hill. 



Although the sea lungwort has long been known to grow on 

 Nantucket, reaching there the southern limit of its range, it 

 seems to have remained always one of the island's rarer plants 

 and never to have established any permanent colony. Nor is it 

 known that more than a few plants have ever been found together 

 on the island. It seems to appear sporadically, and to disappear, 

 at widely separated points along those miles of seashore that, 

 it might be thought, would offer good encouragement to its 

 continued growth. These circumstances of its occurrence suggest 

 that its seeds may come to the island from time to time by some 

 natural agency of dispersion but that the plant is unable to over- 

 come some condition in the environment not quite favorable to 

 its particular needs. Mrs. Owen has recorded the occurrence of 

 a single plant on the north shore at Brant Point, one or two on the 

 south shore, and a few large plants on the southeast shore between 

 Siasconset and Sancoty. I, myself, have met with it only twice; 

 on the sand strip between Sachacha Pond and the ocean, two 

 small sterile plants, September 6, 1904; and at Coskaty, a solitary 

 plant in full flower, June 12, 191 1.
