Ontario County 



Lysimachia terrestris x thrysiflora Fernald & Wiegand 



(Rhodora, i2\ 140. 1910) 



Canandaigua. Miss E. C. Webster, June 24, 191 1. 



This plant had been labelled by Doctor Peck as"Naumbergia 

 thrysiflora with terminal spike," but possesses also lower ax- 

 illary spikes of flowers producing sterile capsules. The terminal 

 spike has all the appearance of that of L. terrestris, but bears 

 near its base two lateral undeveloped short-stalked spikes in the 

 axils of small leaflike bracts. The plant has the unmistakable ap- 

 pearance of being a hybrid between the two named species. 



Megalodontia Beckii (Torrey) Greene 



(Bidens Beckii Torrey) 



Honeoye lake. M. S. Baxter 3641, August 15, 192 1. 



This remarkable species was first collected at Sander's lake, Sche- 

 nectady, by Dr L. C. Beck, in flower. Paine's catalog (1865) adds 

 the following localities : Canaderaga lake, outlet of Schuyler's lake, 

 Oneida county, Oswego Falls, Sodus bay, and outlet at Owasco lake. 

 Mrs Goodrich (PI. of Onondaga Co. 189. 1912) reports it from 

 Tully. Doctor Wibbe (Torr. Club Bul., 10: 46. 1883) reports it 

 from Paddy lake. Oswego county, and Doctor Allen collected it at 

 Saratoga lake (Torr. Club Bul., 21: 497. 1894), which collection 

 is the basis for M. nudata Greene (Pittonia. 4: 271. 1901), 

 based upon characters of doubtful value, and apparently representing 

 merely a " habitat variant " such as frequently occurs in Ranun- 

 culus delphinifolius, and numerous other semiaquatic 

 species.

Cypripedium arietinum R. Br., forma albiflorum, forma nova 



All parts of the flower pure white. Summit lake, northern Otsego
