﻿Plantago major L. 



A weed of roadsides, old fields and waste places. July to 

 September. 

 *Plantago halophila Bicknell. 



A characteristic plant of salt marshes and brackish shores, 

 sometimes extending along roadsides. Flowering during August 

 and September. 



Excessively abundant in fields and grassy places everywhere. 

 Dark green glabrate plants and paler and narrower leaved very 

 hairy forms, mainly of poorer soils, constitute markedly divergent 

 varieties of this species. Forms with dark, ovate, compound 

 heads are frequent, as well as sharply contrasting forms having 

 the spikes linear and elongated. Blooms from May until October. 

 Plantago decipiens Barneoud. 



Frequent or, locally, rather common in salt marshes and along 

 shores, blooming from August through September. 

 *Plantago aristata Michx. 



A few plants on Little Neck, September lo, 1904, in flower and 

 fruit; near Brant Point, September 13, 1907; one plant in a waste 

 yard June 27, 1910; a scattered growth in a dry field in Shawkemo, 

 in full flower July i, 1912. Abundant and evidently long estab«- 

 lished on Martha's Vineyard, and also extending all along the sandy 

 roadway that crosses Chappaquiddick Island, but on Nantucket 

 apparently of only recent introduction. 



RUBIACEAE 

 Houstoxia coerulea L. 



Abundant throughout, not only in low moist places but also 

 over the dry plains and commons, and to the tops of the exposed 

 rolling hills. In the southwest quarter of the island it even 

 overspreads the sandy wastes near the shore, in association with 

 Sisyrinchitim arenicola, these being the most noticeable plants 

 flowering there in early June. In full flower May 30, 1909; it 

 continues quite generally in bloom into July, and produces belated 

 flowers in August and even in September.
