A monstrosity of this plant has been gathered on Hidden lake, south 

 Herkimer county. Several flowers were found, all having many petals nearly 

 white, around three lips also white veined with purple, except their centers, 

 which were covered with a heavy deep green beard. 



The peculiarities of these flowers are that they have three labella, and that 

 the column is resolved into small petaloid organs. The blossom is normal as 

 to the proper perianth, except that the labellum is unusually papillose, 

 bearded almost to the base. The points of interest are, first, that the two 

 accessory labella are just in the position of the two suppressed stamens of 

 the outer series viz. of A 2 and A 3 , as represented in the diagram (Darwin, 

 Fertilization of Orchids, p. 292) ; and there is a small petaloid body on the 

 other side of the flower, answering to the other stamen A 1 . Secondly, in one 

 of the blossoms, and less distinctly in another, two lateral stamens of the 

 inner series, a 1 and a 2 , are represented each by a slender naked filament. 

 There are remaining petaloid bodies enough to answer for the third stamen 

 of the inner series and for the stigmas, Gray in Linn. Soc. Jour. Also Sill.
