positive sign of fusion in the bracts or other part of the flower, seemed, 
however, to negative the idea of fusion.! 
A similar illustration, for a knowledge of which the writer is in- 
debted to the kindness of Professor Asa Gray and Mr. Darwin, occurred 
in some specimens of Pogonia ophioglossoides collected by Dr. J. H. 
Paine in a bog near Utica, New York. It will be seen from the fol- 
lowing description that these flowers presented an almost precisely 
similar condition to those of the Ophrys aranifera just mentioned. “The 
peculiarities of these flowers,” writes Professor Gray, “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 
A2 and a3, as represented in the diagram, fig. 192; and there is a small 
petaloid body on the other side of the flower, answering to the other 
stamen, Al. Secondly, in one of the blossoms, and less distinctly in 
another, two lateral stamens of the inner series (a1 and a2) are repre- 
sented 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, but their order is not well to be made out in the dried 
specimens.” It may here be mentioned that Jsochilus is normally 
triandrous. 
A tetrandrous flower of Cypripedium has also been recorded. 
In Isochilus, according to Cruger, there are often five stamens, and
