thirty-three species of orchids have been collected 

 in a given space of five square miles. This being 

 so, it looks as though I can now safely lay claim to 

 second honours for the Province of Quebec. 



Appended is an annotated list of the twelve new 

 species found this year (1919), as well as an ab- 

 breviated one, for the benefit of those wishing to see 

 at a glance, the total number of orchids, approxi- 

 mate dates when, and number of stations at which, 

 they have been found. 



Large Round-Leaved Orchis, Habenaria or- 

 biculata (Pursh) Torr. I first came across this or- 

 chid on June 8, four plants in leaf only being found 

 at this date. On subsequent visits, however, I in- 

 creased this number to eleven, but none of these 

 bloomed, with the exception of one, which when I 

 went to gather it the first time, was not quite fully 

 out. Returning a few days later, 1 was disappointed 

 to find that the flower had been eaten off, probably 

 by some cows, of which there were a good many 

 grazing in the immediated neighbourhood. Most of 

 the plants were growing under hemlock trees, in 

 company with C. acaule and E. tesselata 



Habenaria macrophylla Goldie. In addition to 

 the eleven plants mentioned above, were two with 

 very much larger leaves than any of the others. 

 Fortunately one of these bloomed, and I think 

 I am justified in recording it as macroph\)lla, 

 for in addition to the size of its leaves, the 

 scape was 41 cm. high, and none of the spurs 

 were less than 3 cm. long, both of these dimen- 

 sions considerably exceeding those given in Gray's 

 Manual for orbiculaia. The raceme was I I cm. 

 long and 5 cm. through, and held fourteen flowers. 

 I first found this particular plant on June 13, the 

 scape then being 18 cm. high, which had increased 

 to 28 cm. by June 22. It was not, however, until 

 ihe beginning of July, that its full height of 41 cm. 

 was attained, and by the thirteenth, all the fourteen 

 flowers were fully developed, making it, if not exact- 

 ly a showy, still a fine, and uncommon looking 

 plant, in my opinion. 



X Habenaria Andreri'.sii, White. I have no ver- 

 nacular name for this supposed hybrid between H. 

 ps^codcs and H. lacera. I first came across it on 

 July 26, when I found one perfectly white bloom, 

 and one almost so, the top of the raceme only being 

 suffused with pink. They puzzled me at the time, 

 but I en'.ered the record in my Gray's Manual un- 

 der the above, with a note of interrogation, however, 

 scarcely believing that they could be Andrewsii, 

 seeing that there were no H. lacera about. For- 

 tunately about a week after, I had the pleasure of 



Mr. Ludlow Griscom's company for a few days 

 botanizing, and on August 3, he came across an- 

 other plant, which also puzzled him. However, on 

 taking it home and critically examining it, he came 

 lo the conclusion that it was really Andrewsii, and 

 on submitting it to Mr. Oakes Ames, his identifica- 

 tion was confirmed, Mr. Ames at the same time 

 questioning the correctness of regarding it as a hy- 

 brid between H. ps^codes x lacera. I understand 

 the plant has been found commonly in Newfound- 

 land, which has also aroused suspicion as to its be- 

 ing a hybrid between H .psycodes x lacera. It may 

 be of interest to here give Mr. Oakes Ames' exact 

 label of determination of the above specimen, which 

 IS as follows, viz.: "Habenaria Andrewsii Wh.fs? 

 The divisions of the labellum not as deeply fringed 

 as in Andrew's specimens from Vermont. This 

 specimen is more like material from Newfoundland 

 (Fernald and Wiegand 5216). The raceme of 

 this specimen is rather characteristic of the hybrid. 

 It may be convenient to regard it as of hybrid 

 origin, with psycodes lacera parentage!" It seems 

 obvious from this comment, that my failure to find 

 Ic.era anywhere in the district, is an interesting 

 piece of evidence. 



Large Purple Fringed Orchis. Habenaria 

 firr.briala (Ait) R. Br. It was not until July 10, 

 that I came upon a colony of these delicate belles 

 of the swamp, as Thorcau calls them, alluding to 

 the peculiar charm of the pale pink flowers. The 

 larger, paler flowered, and usually more open 

 raceme, distinguishes this species from its cousin H. 

 p5i;coJes, besides which it generally occurs in more 

 shady situations than the latter. One very fine 

 plant that I found, had a total height of 9.5 dm., 

 the raceme being 18 cm. long by 5 cm. through, 

 and the four large leaves were 16-18 cm. long by 

 6-10 cm. broad. My dates for fresh blooms, range 

 from the tenth to about the middle of July, but 

 judging from the conditicn of those on the tenth, it 

 is evidently to be found somewhat earlier. 



Grass Pink, Calopogon pulchellus (Sw.) R. 

 Br. The peculiarity of this lovely magenta crimson 

 orchid, consists in i!s not having the ovary twisted, 

 so that consequently the lip is on the upper, instead 

 of the lower side of the flower. Apparently it is 

 rare at Hatley, for I have only found one station 

 for it so far, in the large bog to the north-east of the 

 village, and then only a very few plants could be 

 located. It was in bloom from July 8-15. 



Slender Ladies' Tresses, Spiranthes gracilis 

 (Bigel) Beck. This slender little orchid like the 

 Grass Pink, is apparently rare here, only one sta-
