scarcely applicable to the Ophrydez, in the monstrous forms 
of which, four lateral processes occur, and apparently in ex- 
traordinary situations. 
On this head Mr. Brown remarks. © For in this case, in 
which three anthers are formed, auriculz not only exist on the 
middle or ordinary stamen, but one is also found on the upper 
side of each of the lateral anthers, which are here opposite 
to two divisions of the outer series of the perianthium. 
Great light is thrown on the conformation of Orchidee by 
the monstrosity of Habenaria bifolia, quoted by Mr. Brown,as 
casting great doubt on this hypothesis being applicable to these 
auricule of Ophrydee. ‘ For’ (Mr. Brown says) “in this 
case, in which three anthere are formed, auricule not only 
exist on the middle, or ordinary stamen, but one is also found 
on the upper side of each of the lateral anthere, which are 
here opposite to two divisions of the outer series of the 
perianth. It is evident here that there is a strong tendency 
to become hexandrous, the only doubt of the applicability of 
my idea to this monster, exists in the processes of the 
lateral stamina being on the upper side.” 
Epipactis in Bauer's illustrations t. 20 is well worth study, 
In fig. 6, I take the usual structure to be, one anther deve- 
loped, with traces of other four, of which the two cellular 
bodies represent the anthers opposed to the two lateral se- 
pals ; the intermediate teeth, those opposed to the two lateral 
als. 
In Bauer's Epipactis, it is obvious that the only stamen 
unrepresented is that opposite the labellum. 
10. Тһе same parts are visible, but the teeth oppo- 
site the lateral petals are antheriferous. 
isis very remarkable, for the development is that in 
which the formation of cellular bodies indicates some profi- 
ciency, no greater regularity of the column appears to exist 
in these monstrous cases, than in the normal ones. 
' Now, what is the usual situation of these lateral processes 
in those genera in which they are of constant occurrence? ;
