nearly related to C. Roei. In contrast to the new species, 

 however, C . Roei is a much larger plant, with narrow linear 

 leaf and bigger flower; it has caudate sepals, and the middle 

 lobe is simply recurved and not reduplicated ; there are two 

 yellow glands at the base of the column, and the latter, though 

 markedly winged, does not bear the wide hatchet-shaped wings 

 of C . Bryceana. 



Pterostylis VereenjE, sp. nov. 

 Found by Miss Vereena Jacobs growing in fair numbers 

 amongst Hakea, Tetratheca, etc., in stony soil at Cherry 

 Gardens, South Australia, about the middle of September. 



Description : — 



A plant of slender habit, 4 to 5J inches high. Leaves 

 in a radical rosette, sessile, lanceolate-ovate, 7-nerved, reticu- 

 lated. Bracts two, one near the base, the other about the 

 middle of the stem ; very large, leaf-like, broadly lanceolate, 

 sheathing at their base, reticulated. 



Flower single, about f inch long, green. Galea erect, but 

 abruptly curved forwards towards the end, terminating in 

 rather an acute point. The conjoined sepals enclosing an 

 acute sinus ; tapering into fine points embracing the sides of 

 the galea and then bending forward. Labellum on a move- 

 able claw, spathulate-lanceolate, moderately recurved towards 

 the end, tip not very acute; traversed throughout its length 

 by a raised mesial ridge, with two or three longitudinal veins 

 on each side of it; under-surface of lamina with a deep mesial 

 furrow corresponding to the ridge ; reaching to a higher level 

 than the anther, the recurved portion showing through the 

 sinus of the conjoined sepals; basal appendage curved, its 

 tip trifid, penicillate. Column 6 lines (including anther) ; 

 upper angles of membranous wings produced into an acute 

 tooth, lower angle into a ciliated, blunt, linear-oblong lobe. 

 Stigma narrow-lanceolate, occupying middle third of column, 

 its upper, angle toothed. 



This species falls under Section Antenncea, series Grandi- 

 fiorce, of the Flora australiensis. It is most closely related 

 to P. pedunculata, P. nana, and V . pyramidalis. From P. 

 pedunculata it is readily distinguished by the bracts upon the 

 stem, conspicuously large and leafy in P. Vereence, small in 

 P. 'pedunculata ; by the labellum, narrow at the proximal end, 

 gradually increasing in width towards the distal end, whereas 

 in pedunculata the labellum is ovate, wide at the base and 

 narrowing towards the tip ; by the stigma long and narrow- 

 lanceolate in the former species, short and ovate in the latter. 

 It differs from P. nana in the large bracts upon the stem ;
