Labellum sessile, sharply leflexed about its middle, apex 

 protruding between lateral sepals ; white with a large crenu- 

 lated membranous portion ; callous part relatively small and 

 not very thick, extending only a short distance beyond the 

 bend. 



Column prune-coloured. 



Lateral appendages lanceolate-falcate, about as high as 

 rostellum with a short rounded lobe at the base. 



From the angle where the basal lobe is given off there 

 proceeds a finger-like process which incurves towards the 

 caudicle. 



Caudicle about h length of pollinia. 



Lateral index about 96. 



Blooms September and October. 



Recorded only from Cherry Gardens and Blackwood. 



7. P. album, Rogei-s, .sp. nov. PI. x.a, figs. 1 to 9. 



This is usually a smaller plant than F. odoratum, and 

 with smaller flowers, but with similar colouring, except that 

 there are fewer pink tints. 



The flowers are not scented. 



Lateral sepals about 4 lines, free, pinkish, lanceolate 

 with cylindrical tips, concave upper surface, and rather di- 

 lated base. 



Dorsal sepal nearly 4 lines, not recurved. 



Petals, 3^ lines, linear-lanceolate. 



Labellum on a short claw, obovate-lauceolate, margin 

 of erect portion entire. Otherwise similar to but smaller 

 than F. odoratum. 



Lateral appendages quadrangular-falcate, with ovate- 

 lanceolate basal lobes reaching about halfway up. 



Anther-case much shorter than rostellum, pointless. 



Stigma and caudicle as in F. odoratum. 



Lateral index about 92. 



Recorded from Victor Harbour and Grunthal. 



8. P. pruinosutn, Rogers, sp. nov. PI. xi.B, figs. 1 to 8. 



A rather slender species about a foot high. 



Fistula about 2 in. below spike. Lamina of leaf usually 

 shorter than spike, but sometimes exceeding it. 



Spike 3 to 4 in. long. Flowers about 7 lines, 15 to 20, 

 crowded, and placed more closely to axis of spike than in 

 P. Fitzgeraldi, light prune-coloured, not scented. 



Lateral sepals slender, a little over 4 lines, free, green- 

 ish-yellow, parallel or slightly converging fluted on upper 

 surface.
