beautiful flowers do not preserve their colours well when dried, 

 and do not make such attractive sheets as those of Pogonia, 

 Calapogon and Arethusa. 



Spiranthes lucida (H. H. Eaton) Ames. Wide-leafed Ladies' Tresses. 

 This is one of our rarest orchids and only two plants were 

 found. The first was in flower on July 2, 1905, on the wet 

 river-front below the Victoria Hotel, Aylmer, P.Q., but the 

 habitat has since been destroyed. The second plant grew by the 

 brookside near Old Chelsea and was collected Sept. 20, 1908., 

 withered but still retaining some of the seed-filled ovaries. 



Spiranthes cernua (L.) Richard. Nodding Ladies' Tresses. 



This is the most fragrant of our Ladies' Tresses, growing in 

 cold wet soils and blooming late in the autumn. It was formerly 

 common in the old gravel-pit at Britannia, Ont., and of recent 

 years was abundant in a swampy meadow lying between the 

 Kingsmere hills and Simmon's Corners, P.Q. Collected 

 Britannia Sept. 20, 1905; Kingsmere, Sept. 6, 1909. 



Ranunculus aquatilis L. var. caespitosus D.C. White Water Crow- 

 foot. 



This dwarfed and small-flowered emersed form of the water 

 crowfoot was common Sept. 19, 1908, spreading over the mud 

 flats, exposed by the low water of that year, along the shore 

 below the Country (Tub. The common immersed form var. 

 capillaceus D.C. was also abundant in the stream. 



Dent aria laciniata Muhl. Cut-leafed Tooth wort or Pepper-root. 



This plant, as listed in the Flora Ottawaensis, was collected 

 in a limited area at Beechwood, Rockcliffe, near the Cemetery, 

 and I obtained specimens there on May 13, 1906. A second 

 locality for this species was discovered in the woods near the 

 angle of the road which branches toward Old Chelsea as one 

 comes cityward from Kirk's Ferry, May 26, 1906. 



Cardamine parviflora L. Small-flowered Bitter-cress. 



The only example observed of this little species was col- 

 lected, July 4, 1909, on the rocky western summit of King's 

 Mountain, Kingsmere. 



Podostemum ceratophyllum Michx. River Weed. 



The afternoon and evening of September 14, 1908, were 

 spent by me at the Experimental Farm with Fletcher in entomo- 

 logical and botanical work and conversation, etc., during which 

 he gave me directions for finding the habitat which he had dis- 

 covered for the River Weed. Little did I then think that these 

 would be the last of the innumerable pleasant and profitable 

 hours in which I had the privilege of enjoying the genial com- 

 panionship, the over-flowing hospitality and the unlimited assist- 

 ance and encouragement of my gifted and lovable friend and
