The anther and pollen-masses of BuetTia TANKERVILLIZ ; 
from sketches by Mr. Bauer in August 1801. This plate 
illustrates the structure of the Tribe called EPIDENDREZ. 
— 
. A young anther seen in front; magnified 8 times. 
._ A side view of the same. 
bo 
3. A vertical section of one of the lobes of the same, shewing the early 
formation of pollen in the solid substance of the anther, and the 
origin of the filaments or straps by which the masses are finally 
connected. 
aN 
. A view of the face of the lobes of the anther; magnified 8 times. 
5. A back view of fig. 1. shewing that there are three vascular cords that 
pass out of the column into the anther. 
6. 7. Transverse and vertical-tangental sections of the young anther, 
shewing that the pollen-masses are all originally secreted in different 
parts of the substance of the anther, which at first is a solid mass. 
8. 9. Grains of pollen magnified; fig. 8, 100 times, fig. 9, 200 times ; 
to shew that they cohere in threes or fours, and are themselves 
composed of more minute particles, as is apparent from fig. 9. 
10. A full-grown anther dropping out its pollen-masses; magnified 
8 times. 
12. A view of the underside of the same. 
14. A side view of the same. 
13. A view of the interior of the anther, shewing the eight cells for the 
reception of the same number of pollen-masses ; magnified 8 times. 
11. 16. 17. Various views of the pollen-masses, shewing that the eight 
lobes are all connected by filaments or straps, which unite at the 
apex of the anther. 
15. A section of the anther, shewing the thickness of the connectivum 
and the space occupied by the masses of pollen. All these figures 
are magnified 8 times in diameter.
