1921] Fernald, — Expedition to Nova Scotia 99 



the region of open, boggy barrens east of Argyle Head; Bissell, Linder 

 and I examining the granitic coast of extreme southwestern Nova 

 Scotia at Shag Harbor. We got into a typical Hudsonian bog 

 region like bits of the outer coast of eastern Maine 1 or of Newfound- 

 land, with their great abundance of Bakeapple (Rubus Chamaemorus), 

 Carcx pauciflora, C. trispcrma, var. Billingsii, Empetrum nigrum, 

 and swales of Eriophorum callitrix or interrupted turf of Scirpus 

 cespitosus, var. callosus Bigelow. 2 Around the shores were the usual 

 coastal plants of this latitude, such as Elymus arenarius, var. villosus 

 E. Meyer, 3 Cocloplcurum lucidum (L.) Fernald, 4 and Euphrasia pur- 

 purea Reeks, var. Randii (Robinson) Fernald & Wiegand, but here 

 apparently all belonging to the white-flowered forma albiflora Fer- 

 nald & Wiegand; 5 and the only traces of a coastal plain flora noticed 

 were the ubiquitous Sisyrinchium atla?iticum, Carex atlantica and C. 

 b%lllata, var. Greenei and the almost ubiquitous Bog Huckleberry, 

 Gaylussacia dumosa, var. Bigelov^iana Fernald, 6 northern bog variant 

 of a wide-ranging coastal plain species. 



But when, returning to Yarmouth, Long and Pease joined us on 

 the train, although they had some boreal species, such as Seirpus 

 cespitosus, var. callosus and Carex oligosperma (boreal, but found 

 on Cape Cod), they showed a very different lot of plants from the 

 bog-barrens east of Argyle Station and the peaty and sandy soil 

 about Sand Pond. They were beaming over the prompt discovery 

 of Schizaca pusilla (fig. 11), a young Bartonia, a young Xyris sug- 

 gesting the coastal plain X. caroliniana and, in flower, the northern 

 representative of the genus, X. montana, a young Solidago of the 

 subgenus Euthamia, obviously related to the coastal plain S. tenui- 

 folia, Eleocharis Robbinsii of coastal plain sloughs south to Florida, 

 Panicum spretum, a common species of the coastal plain south to 

 Texas, Calamagrostis Pickeringii, var. debilis Fernald & Wiegand, 

 heretofore unknown 7 between eastern Massachusetts and Newfound- 

 land, Lycopodium inundatum, var. Bigchvii (L. adpressum (Chapm.)
