65 (1921). LuxENBURG 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, l. c. (1921). C. Saururi Engelm. Am. 
Journ. Sci. xlii. 339 (1842). YamMovurH 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 Hevision of the North American and West I ndian 
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, | 
Rnopona, xxiii. 288 (1922). Rocky barrier beach, Markland (Cape

East Jordan.

of the material collected in western Nova Scotia, at various stations 
especially near the coast of Yarmouth, Shelburne and Annapolis 
Cos., belongs to the variety with velvety or densely pilose foliage.
