NEW AUSTRALIAN ORCHIDS. 



137 



claw, cordate, but not emarginate, having a small tooth in the 

 centre, yellow, smooth, but having a broad linear red plate in the 

 centre and thickened red edge. "Wings of column not covering the 

 stigma, extending from the claw beyond the rostellnm, deeply bifid, 

 the upper division the longer, both linear acute. Stigma lanceolate. 

 Anther short and deep, with rather short subulate point (not 

 bearing a gland). New South Wales. 



P. reflexum, sp. n. — Stem slender, about one foot high. Bract 

 sheathing, acute, one and a half inches or more from the flowers. 

 Flowers opening, red-brown, in rather close spike of twenty or 

 more flowers. Sepals two lines long, broadly lanceolate acute, 

 united for half their length, without glands. Dorsal sepal one line 

 and a half long, hooded, ovate-lanceolate acute, with fine point, but 

 no gland. Petals longer than dorsal sepal, lanceolate acute, fim- 

 briate on both edges towards the end, without gland. Labellum 

 articulate, on short claw, thick, oblong, recurved at a right angle, 

 the point being also recurved and fringed, having orbicular reflexed 

 lobes about the centre, and two broad thickened longitudinal plates, 

 red-brown. Wings of column not covering the stigma, extending 

 from the claw beyond the rostellum, deeply bifid, the upper 

 division acute and ciliate on the upper edge, the lower blunt, 

 falcate, shorter than the upper. Stigma ovate-lanceolate, short. 

 Anther short, with rather long mucronate point, bent at right angle 

 in the centre (not bearing a gland). New South Wales. 



P. filiforme, sp. n. — Stem very slender, about eight inches 

 high. Bract eheathing, with almost subulate point, about one 

 inch from the flowers. Flowers opening, very light yellowish red, 

 in loose spike of about eight flowers. Sepals a quarter of an inch, 

 recurved, united for a quarter of their length, linear-lanceolate 

 acute, the fine point not bearing a gland. Dorsal sepal hooded, 

 lanceolate acute, reflexed, the fine point not bearing a gland. 

 Petals two lines long, narrow-lanceolate acute (the fine point not 

 bearing a gland), minutely ciliate on the edges. Labellum articu- 

 late, on a short claw, oblong, lanceolate, mucronate, smooth but 

 crinate along the edges, the point reflexed (not bearing a gland). 

 Wings of column extending from the claw and about a fifth of its 

 length beyond the rostellum, slightly bifid, the lower division long 

 and almost filiform, the upper very short and crenulate. Stigma 

 very short, oblong, with very large rostellum. Anther larger than 

 in other closely allied species (except P. Jimhriatum), with very long 

 point, which is filiform, recurved twice the length of the anther 

 itself (not bearing a gland). New South Wales. 



Diuris tricolor, sp. n. — Stem more than one foot high. 

 Leaves two, linear, channelled, four to six inches long. Bracts two 

 or more, sheathing. Flowers six or more, yellow, with purple 

 centre and purple claws to the petals, and with green lateral sepals. 

 Lateral sepals from an inch to an inch and a half long, linear, 

 deflexed. Dorsal sepal ovate, embracing the column, about half an 

 inch long, yellow with purple centre. Labellum about four lines 

 long, three-lobed, the lateral lobes three lines long, thick, truncate, 

 oblong, the end denticulate, spotted with purple. Middle lobe
