﻿FLOWERING PLAXTS OF NaXTUCKET 335 



vARiA LiNARiA (L.) Karst. 



Linaria vulgaris Hill. 



Another one of our common weeds that does not make head- 



y on Nantucket. I have met with it there on only three 

 1899, at Siasconset, a few plants together; in 1904, 

 a single patch on the south shore at the site of the old Surfside 

 hotel ; and in 1912, by the Wauwinet road in Squam, a small colony 

 in full flower July 12. As far back as 1888, Mrs. Owen reported 

 it as "not infrequent on the edge of the town," where today, if it 

 has not died out entirely, it must be extremely scarce. It occurs 

 on Tuckernuck and is frequent on Martha's Vineyard, but seems 

 to be absent from Chappaquiddick Island. 

 Linaria canadensis (L.) Dumort. 



One of the common plants of sandy and sterile soils. First 

 flowers May 30, 1909, June 4, 1911; in full flower June 7, 1908; 

 continues to bloom well into September, 



*SCROFHULARIA LEPORELLA Bicknell. 



Scarce. In September, 1899, a colony of some twenty plants, 

 the tallest nearly five feet high, grew at the border of a thicket 

 in Squam. Five years later, and many times since then, this 

 station was searched for in vain ; probably none of the plants had 

 survived the encroachment of the woody growth that had at first 

 given them protection. Not until 1910 was the species seen 

 again when two spindling flowerless plants were found at Watt's 

 Run. The next year much of it, in full flower on June 9, raised 

 its tall stems along a low shore thicket in Quaise, and on July 5, 

 1912, a group of some fifteen plants were in full flower in low open 

 ground near Miacomet Pond. Collected in a yard on West 

 Silver street July i, 1911, by Miss Grace B. Gardner. It occurs 

 on Martha's Vineyard, there being two stations on Chappa- 

 quiddick Island. 



It is interesting that the wide variation in leaf form to which 

 this species is subject may be seen in its extremes in the small and 

 isolated colonies found on Nantucket. In plants rising side by 

 side the leaves of one may be evenly close-serrate, of the other 

 coarsely and irregularly laciniate, or even doubly laciniate, with 

 salient triangular to lanceolate-attenuate teeth. Even this ragged-
