1921] Fernald, — Expedition to Nova Scotia 1G7 



conventional but still very choice coastal plain species was Rhexia 

 virgin tea, which we had had only from Randel Lake; hut the great 

 surprise was a boggy savannah at the border of the lake where, at 

 least close to the lake, the two dominant sedges were the northern 

 Car ex oligosperma (Labrador to Great Bear Lake — at the Arctic 

 Circle, south to northern Pennsylvania, Michigan and Minnesota) 

 and Eleocharis tuberculosa (Texas to Florida and north to eastern 

 Massachusetts, see fig. 14). On the way back to the railroad and 

 again near Pubnico station we were greatly interested in Spiranthes 

 cernua, vox. ochroleuca. Typical white-flowered S. cernua, with de- 

 licious fragrance suggestive of the Pond Lily, had been common and 

 blooming freely in sterile meadows but this much larger plant with 

 elongate bracts and yellowish flowers of disgustingly pungent odor 

 was just beginning to bloom and grew in dry habitats, either open, 

 sandy fields or rocky barrens. 



After making a circuit on the 7th, to secure fruiting material of 

 Rxibus and other specialties, we quickly packed the boxes and on the 

 9th sailed on the Prince Arthur, satisfied with our summer's work, 

 though fully conscious that we had barely scratched the surface. 

 Of the more than 2,b00 lakes in the silicious belt we have visited 

 exactly 40 and have almost made the circuit of just 1 ; of the innumer- 

 able savannahs and inland marshes we have been on 4; we have not 

 touched the sandy valleys of the Clyde, Roseway, Jordan, Sable 

 and other rivers to the east; the regions where Ilex opaca and Rhodo- 

 dendron maximum have been reported are still to be investigated; and 

 we have not yet located Ceratiola. 



But the season was not yet over. Many problems promptly arose 

 as soon as the material was unpaeked, so, on October 5, Linder and I 

 sailed on the Prince George back to Yarmouth where we spent three 

 strenuous days, out from sunrise to sunset, collecting fruit of critical 

 groups and adding whatever of novelty the lateness of the season 

 would allow. 



A Bidcns growing in a cold bog at Sand Peach, a plant we had 

 earlier collected in the most immature condition, seems like B. con- 

 nuta, var. gretcilipes Fernald 1 of the Cape Cod cpjagmires but its 

 achenes are nearly tvviee as long; apparently an endemic variety. At 

 last we reached Carleton and Kemptville, trailing Sabatia Kenned y- 



'Rhodora xxi. 103 (1919).
