Anatomical views of the stigma and stigmatic surface of 
Bletia Tankervilli^; from a sketch by Mr. Bauer in 
1802 . 
1. A section of the anterior lip of the clinandrium, the stigma, and a 
portion of the stigmatic canal before impregnation, if viewed under 
water ; magnified 24 times. The stigma, which occupies the upper 
extremity of the figure, is a close sac of cellular tissue : the stigmatic 
canal is composed of an extremely loose plexus of cellular tissue 
fringed by minute hairs. 
2. The same after impregnation. The stigma is discharging the matter 
it contains ; and the plexus lining the stigmatic canal (a) is con- 
verted into a mass of loose separable oblong bodies, having their 
free extremities pointing upwards. 
3. Some of the same bodies magnified 200 times. They are perfectly 
transparent, and appear to be cellules of an oblong or fusiform 
figure, with one, two, or three granular, more opaque, greenish 
yellow specks, looking like young seeds of an Orchis in the midst 
of loose reticulated testa. 
4. Longitudinal section of a portion of the surface of the upper part of 
the stigmatic canal represented at fig. 2 ; magnified 100 times. 
This is seen under water. 
5. Transverse section of a portion of the dense mucous substance lining 
the stigmatic canal, when viewed after having been kept a few 
minutes under water ; magnified 200 times.
