Herminii sp. Pl. CCLXXXV. Fig. I. 
l. Side view of flower. 
2. Front of ditto. 
3. Side view, sepals removed. 
4. Back view of column and labellum. 
5. Front view of column, a base of labellum, 5 stigma, c 
floor of clinandrium and its furcation into a rostellum, 
apices of the forks turned up and in union with the 
glandule, d pollinia just emerging from the anther, e 
sterile stamina. 
6. Front view same pollinia removed, the same letters have 
the same reference. 
7. Lateral view of a column, the pollinia are now quite 
disengaged from the anther, as they will always be 
found to be at some period, the same letters &c. 
8. Front view more advanced, The stigma is tumid and 
choked up'with the pollinia, which are in a state of dis- 
solution, the stigma hasa tendency to spbacelation, d 
remains of the pollinia. 
9. Pollinium. 
10. Partium situs et alternant. 
I omitted to note whether the gland at length loses its 
adhesion with the rostellum. 
In this the two processes appear opposed to the lateral 
petals, although the reverse is represented in the diagram no. 
10. If they are opposite, the fertile stamen obviously belongs 
to a very different series. I have yet to examine this species 
closely.
