DENDROBIUM. 373 
2. Lateral view of column, labellum removed all but the 
spur. 
3. Front view staminodia caudiculigerous processes of up- 
per stigma, 2 lateral view of the stigmata, shewing also 
a tendency to form processes under these belonging to 
the inside of the spur. 
4. Anther transverse section, the septa towards the well 
marked line of dehiscence, become less evident, but the 
anther is now 4-locular. 
5. Lateral view of column and labellum. 
6. Do. labellum mostly removed as also barren stamen, 
the legs of the anther somewhat lifted up from the 
grooved rostellar processes, and their ends separated by 
force from the gland, which adheres to the rostellary pro- 
cesses. This shews that of all the caudicule, very little 
indeed of it is stig matic. 
7. Long central section of a more advanced bud shewing 
the rostellum, and l-lateral stigma, it is curious that 
from the process of the base of spur an aunulus exactly 
like the stigmatic tissue is formed, it may be really stig- 
matic as it adheres to the lateral stigmata. 
8. Bud fully developed, natural size. 
8a Column and labellum of do. 10 times magnified. 
9. Column in front, the anthers are open, the long line of 
dehiscence, only terminating within a short distance of 
the gland is shewn, a opening of stigmatic canal, ё pro- 
cesses of inside of the spur. 
1. (B.) ‘Same series as 1 to 6, of fig. A., but intended to 
show that the crura of the anthere are quite distinct 
from those of the rostellum 4, times. 
2. Section of column of 8; a rostellum, 4 crus grooved along 
the upper edge, which received the crus of the anther, 
c gland, d anther and its crus, e pollen mass, the cau- 
dicula is round only towards the gland, and here it is 
more white, elsewhere itis yellowish, and has a differ-
