EXPLANATION OF PLATES. 



Plate II. 



Calochilus cuweus. 



The central figures show the*, plant in its natural size. 

 Fig. 1. Upper-Surface of labellum, x 2. Shows the fleshy glabrous 

 rectangular base with the longitudinal raised lines 

 and the hairy triangular lamina. 



,, 2. Side view of the same, x2. Shows the tip of the labellum 

 produced into a ligulate process. 



,, 3. Front view of column, x2. Shows in its upper part the 

 duck-bill anther, immediately below which is the 

 rostellum, situated in the upper concave margin of 

 the stigma. The dark comma-shaped glands are 

 shown within the column wings at the base. 



,, 4. Side view of the same, x2. Shows anther in profile, and 

 also the lateral winging of the column. 



Plate III. 



Pterostylis pusilla. 



Central figure showing plant in its natural size. 

 Fig. 1. A flower (natural size) from the front. 



,, 2. Labellum from above, x3. Note labellum with raised 

 lateral and posterior margins -and soooped-out upper- 

 surface, with long hairs on sides and very short ones 

 on tip and vestigial appendage; the broad claw; the 

 pyriform bodies on the lower-surface are partly to be 

 seen projecting on each side of the labellum at the 

 base. 



,, 3. Lateral view of labellum and claw, x3. 



,, 4. Labellum seen from below, x3. Note the pyriform 

 bodies, one on each side of the deep central channel 

 which traverses the entire length of the lower-surface. 



,, 5. Column from front, x3. Note the membranous wings 

 just below the anther, and the secondary ovate- 

 lanceolate expansion traversed by the narrow stigma. 



,, 6. Column in profile, x3. Note its curvature; also the 

 side views of the anther and the membranous wings.
