In spite of slipfht difference in the shape and curvation of the 

 lateral appendages (see Proc. Roy. Soc. Vict., vol. 2.3, Pt. 1), this speci- 

 ujen seems best referable to the above variety. 



In view of the amount of variation which seems to be shown in the 

 lateral appendages of the column, it is questionable whether too much 

 attention is not attached to them in classification. 



Prasophtllum Suttoni, Rogers and Rees. (Orchidacea). 



Buffalo Plateau, Victoria, Dr. Sutton, December, 1902. 



Plant about 10 inches, fistula about 3 inches below spike, leaf about 

 2 inches. Spike consists of about 9 flowers, from which the colours 

 have been discharged in the process of drying, although the faint tints 

 on all the sepals and the dark tints on the column suggest that these 

 have been purple. The petals look as though they had been white, 

 with a coloured dark central streak. 



Flowers very shortly stalked and subtended b}' a small semi- 

 ovate bract about as broad as long. Lateral sepals about 4 lines, 

 quite free, not gibbous, rather narrow lanceolate, dark stripe down 

 middle, convex below, channelled on top (i.e., labellar side). Dorsal 

 sepals about 3 lines, rather narrowly hooded, pointed, not recurved. 

 Lateral petals broader and longer than lateral sepals, i\ lines, rather 

 broadly linear with triangular tips, membranous, with dark stripe 

 down middle. Lateral index 112. Labellum on short claw, obovate 

 recurved at an angle of about 60 deg. at the middle, proximal part 

 measuring about 2 lines from claw to bend, not gibbous, with entire 

 margins, distal part measuring about 2 lines from bend to tip, latter 

 rather broadly blunt and rounded, margins and surface almost entirely 

 membranous, slightly crenulated ; callous portion rather narrow, 

 channelled, increasing in thickness towards the bend and ending 

 slightly beyond the latter in 2 raised lines. Anther not pointed, 

 hidden l)ehind rostellum and nnich shorter than latter. Appendages 

 of column lai'ge, reaching quite to level of rostellum, falcate, with 

 small basal ovate l()l)e, adnate only to base of column. Rostellum 

 voluminous, purple, much higher than anther, triangular. Stigmatio 

 surface large. Ovary short (about 2 A lines), turgid, obovate, on very 

 short pedicel. 



The s])ccies appears to be perhaps most closely allied to /^ fiarinii, 

 though also related to other species. The examination and descrip- 

 tion of tlu^ ]ilant was carried out jointly l)y Di'. Rogers and Miss Rees.
