probably tlie variety amhignum, as Mr. Dickson writes 

 that the calyx is tomentose and the lobes very long- 

 pointed. 



Tkillium grandiflorum, Salisb. 



Monstrosities of this species are not uncommon in 

 South Western Ontario, a fine series in our herbarium 

 having been received from Mr. J. Dearness, London, Ont. ; 

 Mr. E. Cameron, Niagara, Ont. ; Mr. J. M. Dickson, 

 Hamilton, Ont., and Mr. Wm. Scott, Toronto, Ont. Mr. 

 Dickson, after studying in the field the different forms 

 found in the vicinity of Hamilton, sent me the following 

 notes : — 



" A few years ago several green flowered Trilliums were 

 observed growing in a flat piece of woods on the banks of 

 the Waterdown Creek, near this city. To see if they were 

 persistent and not merely sports of a season, I visited the 

 locality during the latter part of May, 1897, and, upon 

 a close inspection, found several remarkable forms not 

 previously noted. Some of these may be described as 

 below : — 



" 1st. Several with white edgings and markings on sepals. 

 The most remarkable of these had one sepal green, one 

 half green and half white and the third pure white, while 

 both sepals and petals were inserted in a distinct spiral on 

 the axis ; the leaves were normal. 



" 2nd. Leaves and sepals normal. Petals marked with 

 green lines or bands toward the base. 



" 8rd. Leaves and sepals normal. Petals green, with 

 a narrow white margin. 



" 4th. Leaves distinctly petiolate. Petioles one to 

 three inches long; sepals white, with a green stripe 

 down the midrib. Petals narrowed, lanceolate, white, 

 with broad green band in centre, running from base, and 

 terminating near the apex. 



" 5th. Leaves as in No. 4. Sepals normal. Petals
