Dorsal sepal about 5 lines, greenish or pinkish, ovate- 

 lanceolate, often very recurved in very old flowers, incurved 

 in younger ones. 



Lateral petals about Ah lines, pinkish with white tips, or 

 white with bi'ownish mesial stripe, linear-lanceolate. 



Labellum abovit 5 lines, on very short claw, oblong- 

 lanceolate ; sharply reflexed about the middle, tip looking 

 between lateral sepals ; erect portion rather gibbous, its 

 margin almost entire ; antei'ior part bluntly triangular with 

 very crenulated margins ; membranous part white, greatly 

 exceeding tne callous part, ending abruptly just beyond the 

 bend. 



Lateral appendages falcate, with rounded basal lobe ; 

 not quite so high as rostellum. 



Rostellum triangular with bifid apex, slightly higher in 

 the fresh flower than the lateral appendages, and much 

 higher than the anther-case. 



Anther-case without a point; reddish-brown, much 

 lower than rostellum. 



Caudicle strap-shaped, about as long as anther-case. 



Stigmatic surface reniform, just below rostellum, occu- 

 pying whole breadth of middle lobe of column and reaching 

 below to about the middle of the column. 



Pollinia 2, large, each markedly bilobed ; total length 

 of pollinia about 1 line. 



Lateral index about 95. 



This species blooms rather later than F. patens, gener- 

 ally throughout November. 



It is widely but not numerously distributed throughout 

 the State. 



6. P. rotundiflorum, Rogers, sj^. hoc. PI. x.b, figs. 1 to 5. 



This species is chiefly remarkable for the peculiar struc- 

 ture of its lateral appendage. 



Plant about 7 in. in height. 



Flowers about 7 in a spike, presenting a somewhat globu- 

 lar form owing to the tendency for sepals and petals to con- 

 verge together to a point ; yellowish-white ; sessile with small 

 ovate bract. 



Lateral sepals quite free, lanceolate, curving upwards 

 on each side of the labellum, yellowish-green in colour, about 

 3i lines, nearly same length as dorsal sepal and lateral petals. 



Dorsal sepal concave, acuminate, converging towards the 

 points of the lateral sepals. 



Petals bluntly linear, white with pinkish stripe, in- 

 curved, embracing dorsal sepal and erect portion of labellum.
