tion with three plants having so far been discovered. 

 Two of these were found on July 16, and the re- 

 maining one on July 25, but they were not in bloom 

 until August 3. The situation consisted of some 

 very dry hilly knolls, on the outskirts of a large 

 wood, and I am not likely to forget the day, seeing 

 that at the same time I also discovered the Green 

 Adder's Mouth (Microslylis unifolia), and those 

 rare little ferns the Adder's Tongue (Ophioglossum 

 vulgatum), and Little Grape Fern (Bolrychium sim- 

 plex), the dry location for these three latter, being 

 somewhat uncommon, as they generally occur in 

 damper situations as a rule. 



HoDDiGES Rattlesnake Plantain. Epipactis 

 tesselata (Lodd) A. A. Eaton. I really found this 

 orchid away back in 1915, but as it was not then m 

 bloom, and I was unacquainted with the difference 

 in the shape, size, and colouring of its leaves, to 

 those of E. repens, I passed it over, and took it for 

 the latter species. However in the fall of 1918, I 

 came across a few dead scapes, which by their size 

 and height, struck me at cnce as not being repenz, 

 but something new. This idea was further strength- 

 ened in the following spring, when the difference in 

 the leaves was noticed, and later in July when the 

 flowers appeared, all doubt was at an end, as they 

 were then seen to be the present species, and not 

 repens. 



Heart-leaned Twayblade, Lhlera cordata 

 (Lin.) R. Br. This little orchid even if it were 

 common, would nevertheless be hard to find, owing 

 to its small size, and inconspicuous madder-purple 

 flowers. I first came across it on June 8, of the 

 present year (1919), growing amongst spagnum 

 moss, in a damp wood to the north-west of the 

 village, and again on July 8, in the large bog to the 

 north-east of the village, and yet again on August 

 4 (one plant only), in the woods surrounding the 

 great Brule bog near Waterville. some miles also 

 to the north-east of Hatley. In the first mentioned 

 locality, I found bunches of eight, ten, nineteen, 

 and in one case as many as twenty-seven plants, all 

 growing somewhat closely together. In two cases, 

 there was a small bract leaf (the same as often oc- 

 curs in H. obtusata), at the base of the raceme, and 

 in a few the lip was devoid of madder-purple, this 

 giving the whole raceme a green appearance. My 

 dates for fresh blooms, range from June 8 to July 3. 

 In "The Canadian Naturalist," 1840, pp. 

 297-303, Gosse gives a good account of the Brule, 

 describing it as exactly resembling the bogs of New- 

 foundland. It consists of some thousands of acres, 

 and is said to owe its origin to the beavers, which 

 were formerly numerous, damming up the streams, 

 which overflowing and spreading over the flat lands, 

 killed the growing timber. When Mr. Griscom and 

 I visited it for the first time, on August 4, we both 



came to the conclusion, that there were great possi- 

 bilities regarding the place. Seven different orchids 

 were found, even at this somewhat late date, as well 

 as many of the plants, shrubs and trees, mentioned 

 by Gosse as growing in similar situations in New- 

 foundland, including black spruce, which I had not 

 noticed here before. It is hoped to again visit the 

 locality early in June, when good results are ex- 

 pected, especially in regard to the orchids, of which 

 our trip in August gave promise. 



Large Coral Root, Corallorrhiza maculata Raf. 

 It was not until August 9, that I came upon a little 

 colony of this species, consisting of forty plants, the 

 blooms of which were over of course, but the fruit 

 still remained. They were found growing in a 

 small cedar wood, on some dry sloping ground, 

 about two miles to the south-east of the village. 

 Later on, or on August 21, another plant was shown 

 to me on the roadside, some few miles to the north 

 of the present site, but also on the east of the village. 



White Adder's Mouth, Microst^Us monophyl- 

 los (Linn) Lindl. This rare little orchid like many 

 others, is easily passed over, unless you are specially 

 looking for it, which no doubt accounts for my hav- 

 ing found it during the present season (1919), 

 when all my energies were devoted to the fern and 

 orchid families, instead of the birds. The situation 

 was a low damp one, at the edge of a little wood, 

 where twenty-four plants were located. Later on I 

 found one other plant in a similar situation, two 

 miles to the north-west of the village, whereas the 

 first locality was two miles to the south-east of it. 

 The plants were just in their prime on June 30, 

 the day on which I found them. 



Green Adder's Mouth, Mkrosiylis unifolia 

 (Michx) B.S.P. This is another somewhat incon- 

 spicuous little plant, but is much commoner than 

 monophyllos, there being at least five stations at 

 which I have found it, and generally in somewhat 

 goodly numbers. Its habitat seems to vary a good 

 deal, the situation sometimes being very dry, as al- 

 ready mentioned in the account of the Slender 

 Ladies' Tresses, and at others very damp, the same 

 as those favoured by monophyllos. 



Loesel's Twayblade, Liparis LoeselU (Linn) 

 Richard. This is another of those somewhat in- 

 conspicuous little orchids, and one which I must 

 have passed over many times, before finally noticing 

 it in bloom, en July 12 of the present year (1919). 

 It certainly favours very wet boggy places, especial- 

 ly those where the water drains out of the land, at 

 the foot of hill-sides. At present I have located 

 about four stations, where its numbers vary con- 

 siderably, from three plants in one, to some dozens 

 in another. My data for fresh blooms range from 

 June 27 to July 5.
