-9- Rhodora [December 



Valeriana officinalis L. Occasional escape to roadsides. 



** Eupatoriuii VEKTICILLATUM Lam. ace. to Wiegand, Rhodora, 

 xxii. (>2 (1920) = E. PURPUREUM L. ace. to Mackenzie, ibid. 1(35 

 (1920). Yarmouth Co.: cobbly or bushy borders of Salmon (Green- 

 ville) Lake; sandy and rocky border of Tusket River, Tusket Falls; 

 gravelly margin of Tusket (Yaughan) Lake; sandy and cobbly beach 

 of Panning L., Carleton. See p. 147. 



I do not undertake to settle which name should be applied to this 

 coastal plain species. The very fact that two such students as 

 Wiegand and Mackenzie, after prolonged and independent study of 

 the literature, should arrive at such different conclusions is sufficient 

 indication that the identity of the Linnean species cannot be finally 

 settled without close comparisons by someone, who thoroughly under- 

 stands the plants involved, of the various critical specimens in the 

 Old World herbaria. 



E. maculati'M L. ace. to Wiegand, 1. c. (>4 (1920) = E. BRUNERI 

 Gray, ace. to Mackenzie, 1. c. (1920). Rich thickets and swales, 

 Digby Neck to Halifax Co. and Cape Breton. 



SOLIDAGO latifolia L. Locally in rich woods or on calcareous . 

 slopes, Digby Neck to Cape Breton. See pp. 164, 170. 



S. BICOLOB L. Rare or wanting in the southwest; not seen in 

 Shelburne, Yarmouth and southern Digby Cos. 



S. UNILIGULATA (DC.) Porter. Abundant on wet or dryish peaty 

 barrens 1 . Macoun's records of S. itiiginoxa and S. raccmusa ("S. 

 hum ilia") belong here. There are other records of S, vliginoxa but 

 I have seen no material from Nova Scotia. See p. 157. 



S. JUNCEA Ait. Not seen in Queens, Shelburne and Yarmouth 

 Cos. 



S. N EM ORALIS Ait. Rare or wanting in the southwest; not seen in 

 Queens and Shelburne Cos., and seen in Yarmouth Co. only at Carle- 

 ton. Seeming to prefer argillaceous soil. 



** S. Ki.liottii T. & G. Abundant, often dominant, in boggy 

 clearings, swales, damp thickets, spruce and maple swamps and 

 lake shores, Yarmouth Co. eastward at least to Queens. See pp. 

 144, 151, 157, 169. 



* S. RUGOBA Mill., var. VILLOBA (Pursh) Fernald. Apparently 

 frequent throughout. 



Too much of the Nova Scotian materia] is intermediate between S. uniligulata 

 and S. nrglecta T. & G. In Massachusetts, too, these plants are not specifically 

 separable and it seems that Gray was correct in treating them as varieties of one 

 species. Since, however, .S. uniligulata antedates 8. ncglccta they should be com- 

 bined under the former not under the latter name, which was retained by Gray. 

 The varieties of S. uniligulata are as follows. 



S. omuouuTi (DC.) Porter, var. terrae-novae (T. & G.), n. comb. S. Tcrrae- 

 Xi>va< T. &. G. Fl. X. A. ii. 2()(i (1842). 



Var. neglecta (T. & G.), n. comb. S. ncglecta T. & G. 1. c. 213 (1842).
