Prasophyllum viride, sp. ii. — Stem slenderest in the group, 

 aboi;t seven inches high. Bracts leafy, close to the flowers. Flowers 

 not opening, green, gibbous, in spikes of about one inch, not very 

 dense. Sepals gibbous, green, acute, without glands, about a line 

 and a half. Dorsal sepal not quite so long, broadly hood-shaped, 

 with acute points, without glands. Petals longer than dorsal 

 sepals, lanceolate acute with subulate point, transparent. Labellum 

 articulate, on very long claw, concave on under side, triangular, 

 with blunt recurved points, and deep sinus on each side of the 

 hinge ; surface rugose, with slight depression down the centre, 

 yellow, with red claw. Wings of column covering the stigma, 

 bifid, the upper division twice as long as the lower, subulate, 

 minutely ciliate ; the lower blunt, not ciliate. Stigma an acute 

 triangle, and small part only at the end near the rostellum appa- 

 rently stigmatic. Anther short, with short acute point {not bearing 

 a gland). New South Wales. 



P. densum, sp. n. — Stem rather slender, about five inches high. 

 Bract almost subulate, very close to the flowers. Flowers opening, 

 red-brown, in dense spike, hardly more than half an inch. Sepals 

 red-brown, about two and a half lines, narrow lanceolate acute, 

 with fine point bearuig a gland. Dorsal sepal not quite so long, 

 hooded, lanceolate acute, bearing a gland. Petals about one line, 

 lanceolate acute, with point bearing a gland. Labellum articulate, 

 on long claw, linear-lanceolate acute, with a gland at the point, 

 minutely ciliate towards the end ; surface smooth and flat, light 

 red-brown. Wings of column blunt, entire, not covering the

 the point. New South Wales. 



P. eriochilum, sp. n. — Stem slender, about ten inches high. 

 Bract sheathing, an inch or more from the flowers. Flowers 

 opening, brown and green, in rather open spike of about an inch. 

 Sepals gibbous, green and brown, about one line and a half, lanceo- 

 late acute, without gland, united at the base. Dorsal sepal hooded, 

 broadly lanceolate acuminate, without gland, minutely ciliate on 

 the edge. Petals same length as the dorsal sepal, lanceolate, with 

 long point but no gland, and ciliate along the upper edge. Labellum 

 articulate, on sliort claw, ovate-lanceolate, with long ciliate point, 

 the surface, except near the claw, covered with hairs, brown. 

 Wings of column not covering the stigma, bifid, the upper division 

 longer than the lower, both glandular along the edges. Stigma 

 linear-triangular, with large rostellum. Anther short, with small 

 tooth in the centre (not bearing a gland). 



P. ansatum, sp. n. — Stem slender, about four inches high. 

 Bract almost subulate, very close to the flowers. Flowei's opening,
