FRUCTIFICATION.

The sexual apparatus of Orcuis mMascuLa, &c. from a 
drawing by Mr. Bauer in May 1792. This plate illustrates 
the structure of the Tribe called OpHrype&. 
1. A front view of the column of Orchis mascula with the base of the 
labellum, shewing the position of the anther, with its pouch, the 
cells of the former being partially open, so as to shew the pollen 
within ; on each side of the anther are seen two granular tumours, 
which are the rudiments of stamens; magnified 15-times. 
2. A back view of the same; the orifice of a section of the ovarium 
being shewn above the mouth of the spur, a section of which occu- 
pies the centre of the figure ; the spur is seen to be hairy inside. 
3. A front view of the anther with the cells opened, so as to exhibit the 
pollen-masses inside in their natural position ; magnified 15 times. 
The pouch in which the glands of the pollen-masses are confined 
is forced a little down. ; 
4. The same viewed from beneath and behind. The back of the pouch 
is visible, with two foramina which communicate with the glands 
of the pollen-masses, and establish a communication between them 
and the stigma. In an unexpanded state the back of the pouch is 
pressed down close upon the stigma, and at that time the influence 
of the pollen is conducted to it through these foramina; after ex- 
pansion the pouch and foramina are separated from the stigma by 
so considerable a space, that no communication can be established 
between them. See fig. 16. 
5. A transverse section of fig. 3; magnified 15 times. In this the inner 
structure of the cells of the anther is exhibited, and the pouch is 
in its natural position. 
6. A pollen-mass with its caudicula and gland, taken out of the anther ; 
magnified 15 times. 
7. The same; magnified 15 times; its pollen forcibly stretched asunder, 
and many of the granulations torn away.
