65 (1921). Lunenburg Co.: wet thickets and swales back of brackish 

 shore of Lahave River, Bridgewater; upper border of cobbly beach, 

 Wentzell Lake. 



Var. vulgivaga is the typical form of the species as was clearly 

 indicated by Engelmann in publishing it: "It is WilldenoW's original 

 C. Gronovii, in his Hb. nro. 3160." 



**C. Gronovii, var. latiflora Engelm. Trans. Acad. Sci. St. 

 Louis, i. 508 (1859); Yuncker, 1. c. (1921). C. Saururi Engelm. Am. 

 Journ. Sci. xliii. 339 (1842). Yarmouth Co.: thickets and damp 

 shores, Quinan, Argyle and Belleville. A coastal plain variety re- 

 corded by Yuncker as extending from Texas to southern Illinois 

 and New Jersey. 



All our material of var. latiflora from Nova Scotia has large, de- 

 pressed-globose or oblate capsules, in maturity 4-5 mm. broad, and 

 unusually large seeds, 2.2-3 mm. long. Its corolla and anthers are 

 exactly those of the southern plant and, although Yuncker in his 

 recently published Revision, of the North American and West Indian 

 Species of Cuscuta excludes C. Gronovii (in his key, p. 47) from the 

 group characterized by " Capsule globose, more or less depressed," 

 and places it (p. 48) in the group with "Capsule globose-ovoid to 

 conic or long-beaked," many of the specimens placed by him under 

 this species have definitely depressed-globose capsules like the plant 

 of western Nova Scotia. Similarly, although Yuncker 's description 

 of C. Gronovii calls for seeds " about 1.5 mm. long, " many plants which 

 he has identified have seeds up to 2.3 mm. long. The old corollas of 

 C. Gronovii and var. latiflora sometimes crown the capsule. In such 

 cases there is great difficulty in distinguishing the plants with de- 

 pressed-globose capsules from C. Cephalanthi Engelm. In the latter 

 species, however, the anthers are smaller and more rounded than 

 in C. Gronovii. 



Mertensia maritima (L.) S. F. Gray, forma albiflora Fernald, 

 Rhodora, xxiii. 288 (1922). Rocky barrier beach, Markland (Cape 

 Forchu), and very abundant and uniform on the barrier beach at 

 East Jordan. 



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

 Shelburne Co.: crest of barrier beach, East Jordan. 



**Solanurn Dulcamara L., var. villosissvmum Desv. PI. Angers, 112 

 (1818). £. tomentosum Koch, Syn. 507 (1838). y. niacin urn Bab. 

 Man. 210 (1843). S. littorale Raab in Flora, ii. 414 (1819).— Much 

 of the material collected in western Nova Scotia, at various stations 

 especially near the const of Yarmouth, Shelburne and Annapolis 

 Cos., belongs to the variety with velvety or densely pilose foliage.
