I'PTEROSTYLIS SARGENTI, sp. nov.— 
Radical leaves withered beore flowering, and not seen. Scape- 
1-2 flowered, 3-5 inches high. Leaves or empty bracts lanceolate, 
f-i^inch long, clasping the stem with rounded auricles, the lowest one 
or two reduced to sheathing scales. Galea about -J- in. long, curved 
forward; dorsal sepal ending in a short up turned point 1-2 lines long; 
lateral petals very shortly pointed, their junction with the dorsal sepal 
marked by lines of white hairs inside the galea. Lower lip ^ inch 
long, pointing downwards, the entire part as long as the lobes, which 
end in filiform points about 2 lines long and are separated by an acute 
sinus. Labellum on a broad claw, glabrous, 3-lobed ; the middle 
lobe triangular, about 2 lines long, with a ridge down the middle ; 
lateral lobes 1 + lines long, linear-lanceolate, slightly curved, produced 
at the base into erect thick clavate dark-brown appendages fully 2 lines 
long and recurved at the top. Column nearly as long as the galea, 
with short, almost orbicular, wings on either side of the rostellum ; 
the wings with a very short point at the upper outer angle. Anther 
short, not acuminate. 
The specimens were sent to me by Mr. Alex. Purdie, who re- 
ceived them from Mr. O. H. Sargent, of York. Mr. Sargent found 
them flowering in July and August, T904, within a few miles of York. 
The species belongs to the section Calochilus , and in habit and 
general appearance, is not unlike small specimens of P. longifolia , 
R. Br., though the curve of the galea is different and the lower lip is 
more like that of P. rufa , R. Br. The labellum and its appendages 
are quite distinct from those of any other species, and the column 
wings have no lower lobe. I have not seen the lines of hairs inside 
the galea in any other species. 
THELYMITRA PSAMMOPHILA, sp. nov.— 
Stem 5-8 inches high, slightly flexuose. Leaf narrow-linear, 1-A--3 
inches long; empty bracts 2 or 3, leaflike, but only inch long. 
Flowers 2 to 4. Sepals and petals ovate, more or less acuminate, 3 
to 5 lines long, yellow Column-wing continued behind, but shorter
