132 Rhodora [June 



ventional A ret hum bulbosa, Catopogcm pulchellus 1 and Pogonia opkio- 



glossoides were abundant; open turfless spots were brilliant with 

 carpets of the deliriously fragrant (pungent) Utricularia cornuta; 

 and the drier knolls had Uai/lussacia dumosa, var. BigeJoriana; alto- 

 gether a bog with most of the plants a bog ought to have and some 

 which are not always found. 



"The Chief" or "the Old Man" had assigned the pine barrens 

 about Springhill Junction to Long and Pease because that area is 

 conspicuous for its hopelessly barren aspect and it was certain that 

 if any plant of real interest were isolated there it would be detected 

 by that unequalled pair. But when, returning to Truro for the 

 night, they joined me in the dining-car, they reported that the region 

 was the most sterile area imaginable, not only on account of the 

 limited number of species on the Carboniferous sandstone but be- 

 cause practically all of them had given up trying to produce either 

 flowers or fruit. Besides the two pines they had a few really good 

 things which we had not seen in other silicious areas: Ori/zopsis 

 canadensis (Poir.) Torr. (Siipa canadensis Poir.), known from New 

 Brunswick and Prince Edward Island but not met by us elsewhere 

 in Nova Scotia, and Carex aenea and C. albolutescens, var. cumulata 

 Bailey, afterward found on various sandy barrens. They had 

 found one brook-bottom which had some fertility, yielding the only 

 Petantet palmata of the summer; and, while waiting for the train, 

 they had weeded the freight yard and taken away Linaria minor, 

 reported in 1907 by C. B. Robinson 2 from Pictou Landing, and now, 

 as it soon proved, a common weed all along the railroad to Halifax 

 and eastward to Cape Breton; the beautiful yellow-flowered Lathy rus 

 prafensis; and a strange Crucifer which proves to be Erysimum parvi- 

 florum, a western species now beginning to move eastward along the 

 railroads 3 . 



1 Calopogon pulchellus is sometimes called Limadorum tuberosum L., Sp. PI. 9f>0 

 (1753), but that species rests chiefly tipon and draws its specific name directly from 

 ' HeUeborine Americana; radice tuberosa" of Martyn, Hist. PI. Rar. 50, t. 50 (1728). 

 The Martyn reference is the only one of the Linnean citations showing a plate, 

 a beautiful full-page colored drawing of the plant of the Bahamas treated by Britton 

 & Millspaugh (Bahama PI, 96) as Jilelia purpurea (Lam.) DC, although they cite 

 Jacquin's Limodorum altum, the description of which defciitely cited M a synonym 

 Martyn's Helleborine Americana; radice tubcrosa. Limodorum tuberosum L, is, of 

 course, the earliest name for Bletia purpurea.
