1921] Fernald, — Expedition to Nova Scotia 289 



Corollas whitish. — Nova Scotia: gravelly barrier beach, Sand 

 Beach, Yarmouth Co., July 12, 1920, Fernald & hinder, no. 22,349 

 (type in Gray Herb.). See p. 102. 



Verbena hastata L. Not seen west of Hants Co. 



Teucrium canadense L., var. littorale (Bickn.) Fernald. 

 Gravelly coast of Yarmouth Co.: Rockville; Eel Lake; Argyle. 

 On Sable Island and the eastern coast of New Brunswick and south- 

 western coast of Prince Edward Island. See p. 142. 



Nepeta hederacea (L.) Trevisan. We have two well-marked varie- 

 ties of Nepeta hederacea introduced into North America. Typical 

 N. hederacea with the corolla 1.6-2.2 cm. long is apparently rare in 

 eastern Canada. I have seen it from Charlottetown, Prince Edward 

 Island and from a cellarhole at Arcadia, Nova Scotia {Pease & Long, 

 no. 22,366). The commoner plant of eastern Canada has the corolla 

 1-1.5 mm. long and its leaves are inclined to be red or reddish. This 



is 



N. hederacea, var. (parviflora Benth.) Druce, Brit. PI. 57 (1908). 



Judging from the representation before me the two varieties are 

 not uniformly distributed in northeastern America, the representa- 

 tion of specimens from Newfoundland to New England being as 

 follows. Newfoundland: type, 0; var. parviflora, 2. Quebec: 

 type, 0; var., 1. Prince Edward Island: type, 1; var., 1. New 

 Brunswick: type, 0; var., 2. Nova Scotia: type, 1; var., 0. 

 Maine: type, 5; var. 11. New Hampshire: type, 3; var., 4. Ver- 

 mont: type, 6; var., 2. Massachusetts: type, 27; var., 18. Rhode 

 Island: type, 0; var., 11. Connecticut: type, 6; var., 2. 



Stachys palustris L. Roadside ditches, Sand Beach (Yarmouth) 

 and Barrington and collected by others about various ports east- 

 ward. 



True S'. palustris of Europe is clearly only an introduced plant 

 in eastern America, occurring about ports, on waste land, in ditches, 

 etc. from southeastern Newfoundland and Gaspe Co., Quebec to 

 Ottawa, south, chiefly near the coast, to New Jersey. In this intro- 

 duced plant the calyx bears stipitate glands mixed with the long 

 glandless hairs and the pubescence of the stem is short and appressed 

 on the sides, longer on the angles. The indigenous plant of alluvial 

 thickets, river terraces and other rich soil from the Penobscot Valley 

 in Maine to Ontario and southward is var. homotricha Fernald, in 

 which the calyx lacks stipitate glands and the pubescence of the sides 

 of the stem is elongate, often as long as on the angles.
