1921] Fernald, — Expedition to Nova Scotia 131 



rcsinosa, and I going on to Amherst. The two latter areas I had 

 noted from the train on first reaching Nova Scotia, for they were 

 unlike most others which I saw. The chief attraction at Amherst 

 was a series of springy bogs and spring-fed pools by the track south- 

 ward toward Nappan. In one of these pools I had seen from the 

 speeding train a plant which upon reflection I imagined might be 

 Montia rindaris, x a European species known in North America only 

 in southeastern Newfoundland and northeastern New Brunswick. 2 

 Like so many things thus glimpsed from a train, the plant of course 

 was not Montia at all, but a mass of half-emersed Ranunculus Purshii 

 flecked with stranded fragments of Lcmna minor. The latter plant, 

 although widely dispersed in southern regions and abundant in pools 

 and streams of eastern New Brunswick, Prince Edward Island, the 

 Magdalen Islands and northern and eastern Nova Scotia, seems to 

 be absent from western Nova Scotia as are the Ranunculus and Lcmna 

 trisvlca with which it grew. The spring-pools below Amherst had 

 other good aquatics which we had not seen in the western counties : 

 MyriophyUum vcrticillatum, var. pcctinatum, Sagittaria cuneata Shel- 

 don (S. arifolia Nutt.) and, at their margins, swales of Calamagrostis 

 neglect a or solid and almost impenetrable stands of the big bullrushes, 

 Scirpus talidus and S. acutus, forma congestus, 3 the latter a striking 

 extreme growing apart from typical S. acutus and having the spike- 

 lets in a single very dense glomerule. The railroad embankment 

 was beautiful with masses of the Harebell, Campanula rotundifolia , 

 which we had not seen near Yarmouth, and with it a color-form of 

 Butter-ar d-eggs, Linaria vulgaris, only in this form the corolla, ex- 

 cept for the deep-yellow palate, was milk-white. 



The sphagnous spruce-bog nearby is a gem, a spring-fed bog with 

 central pond, its quaking margin full of Carcx limosa and C. diandra, 

 species common enough in the region bordering the Gulf of St. Law- 

 rence but not found all summer in southwestern Nova Scotia. The 

 bog was white with Scirpus hudsonianus and that rare and elegant 

 cotton grass, Eriophorum Chamissonis, forma albidum. 4 The con-
