676 ORCHIDEA. [Prasophyllum. 
dense, few- or many-flowered, 4-14 in. long. Flowers minute, the 
perianth about 51, in. long, curved, pointing downwards, greenish. 
Upper sepal ovate, acuminate, concave; lateral rather longer, free, 
ovate-lanceolate, acuminate. Petals the same shape as the lateral 
sepals, but shorter, and with the tips almost aristate. Lip articu- 
late on a flat ribband-like projection from the foot of the column, 
mobile, oblong, acute, truncate at the base, not ciliate, disc almost 
wholly occupied by a thick adnate plate, which is obscurely 
3-grooved towards the base. Column short, the lateral lobes 
broad, obliquely truncate and irregularly 2—3-notched at the tip. 
Auther large, apiculate, overtopping the small rostellum.—Handb.

4. P. rufum, &. Br. Prodr. 319.—Very similar in size and 
habit to P. pumilum, and like it with the leaf reduced to a sheath- 
ing bract just below the spike, the lamina very short and subulate. 
Spike few- or many-flowered, 4-3in. long. Flowers still more 
minute than in P. punulum, the perianth about 4,12. long, hori- 
zontal, reddish or yellowish. Upper sepal ovate, acuminate, con- 
cave ; the lateral much longer, quite free, lanceolate, acuminate, 
the points tipped with a small gland. Petals small, lanceolate, 
shorter than the upper sepal. lLabellum articulate on a flat rib- 
band-like projection from the foot of the column, mobile, lanceolate, 
acute, truncate at the base, adnate plate occupying most of the 
disc, thickest along the margins. Column very short, the lobes 
rather narrow, 2-toothed at the tip. Anuther large, apiculate, over- 
topping the small rostelluu.— Benth. Fl. Austral. vi. 344; Fitz-

The above description is drawn up from Mr. Macmahon’s specimens, which 
correspond fairly well with the plate of P. rufum given by Mr. Fitzgerald in 
his “‘ Australian Orchids.’’ It is distinguished from the preceding species by 
the smaller horizontal usually reddish flowers, narrower lateral sepals tipped by 
a minute gland, much narrower lip, the adnate plate on which is thickest on 
the edges, and in the narrower latera! lobes of the column. 
10. CALEANA, R. Br. 
Glabrous terrestrial herbs. Root of small rounded tubers on 
fleshy fibres. Leaf solitary, linear or lanceolate or oblong. Flowers 
solitary or 2-4 in a terminal raceme; bracts acute. Sepals and 
petals subequal, all linear; the upper sepal erect, the lateral sepals 
and petals spreading or deflexed (but the position apparently re-
