Plate IV. 



Drakea Huntiana, F. v. M. 



At each side of the plate the plant is shown in its natural 

 size; on the right with two flowers expanded, and on the Left a 

 flower about to expand and several very young buds. 



Fig. 1. Labellum seen from above, x3. In the upper part of the 

 drawing note the columnar foot (projection) articulated 

 with the labellar claw^ which is of about equal length ; 

 also the two anterior peduncles terminating in 

 globular glands and the large triangular gland lying 

 between them ; also the divergent posterior tails with 

 their numerous hairs. 



,, 2. An enlargement of a bud just about to expand. The 

 lateral sepals have already rotated to the opposite 

 side of the ovary, but the claw-like processes of the 

 column have not yet released their grip of the 

 labellum. 



,, 3. Lateral view of fully-expanded flower, x3. Note that 

 the flower appears inverted owing to the acute flexion 

 of the column and perianth segments on the ovary. 

 The claw is seen to be inserted into the under- 

 surface of the middle or thoracic segment of the 

 labellum. 



,, 4. Front view of column, x3. This shows the lower unex- 

 panded portion of the column and also the upper 

 expanded part. In the latter will be seen the upper 

 and lower claw-like processes, the anther between the 

 former and stigma between the latter.
