 tufts white, turned upwards ; intermediate lobe brownish, very deeply and narrowly cleft, 

 the divisions rounded, entire, its crest rather higher than the hair-tufts. Anther only

10. T. fuscolutea (brown-yellow), R. Br. Generally rather stout, 15-45 cm. high. Leaf 

 the widest in the genus, ovate -lanceolate to oblong-lanceolate, contracted and sheathing 

 at base, dimensions very variable, ranging from 4-12 cm. long and H--5 cm. wide. Flowers 

 2-6, large, yellowish marked with dark-brown spots, about 2J cm. in diameter. Perianth- 

 segments elliptic-lanceolate, acuminate, 11-16 mm. long. Column 7-8 mm. long including 

 wings, but very short (only 2mm.) below the anther; wings voluminous, produced 

 behind and beyond the anther in form of a canopy or broad hood, without definite lateral 

 lobes, the upper margins dissected into dentate or linear processes, a dorsal thickening 

 from the base produced upwards into an undivided clavate appendage rather shorter 

 than the linear processes, the summit of the hood in front of the appendage densely woolly. 

 Anther at its apex produced into a long recurved finger-like process ; concealed, with 

 exception of its apex, behind the stigma. Stigma situated in the concavity formed by 

 the wings at base of column. Rostellum prominent in upper border of stigma. No 

 caudicle.

11. T. urnalis [urn-shaped column), Fitzg. A slender plant 10-30 cm. high. Leaf 

 long, linear, channelled, often reaching the base of the inflorescence. Flowers small, 

 1 or 2, yellow inside, the sepals dark red-brown on the outside, buds reddish on outside. 

 Perianth -segments rather wide, acute, about 6 mm. long, opening in warm sunshine. 

 Column about mm. long, not hooded, but wings produced above the anther ; the lateral 

 appendages not ciliate but broad, horizontal, and rugose, the lobe between them undulate 

 or almost denticulate ; vings united in front of the column at the base and sometimes 

 produced upwards in the form of a central spur in front of the stigma, giving the column 

 an urn-like appearance. Anther 2-celled, obtuse, slightly emarginate, protruding above 

 the stigma, after dehiscence carried upwards with the growth of the column, leaving the 

 pollen -masses attached to the rostellum. Pollinia 4 (in 2 pairs) attached directly to the 

 viscid disk and easily removed on a needle.

12. T. carnea [flesh-colored), R. Br. A very slender species, usually 15-30 cm. high. 

 Leaf very narrow -linear, channelled. Flowers 1-3, rather small, pink or red, expanding 

 in bright sunlight. Perianth -segments obtuse, elliptical or oblong-elliptical, about 

 9 mm. long. Column about 5 mm. long, erect, not hooded ; wings produced laterally 

 into 2 denticulate and more or less roughened yellow horizontal lobes, rather higher than 

 the anther ; intermediate lobe rather broad, reddish, slightly denticulate, rather higher 

 than the lateral ones. Anther somewhat blunt, its lower half concealed behind the stigma.

13. T. flexuosa (zig-zag stem), Endl. A very slender species, usually 15-20 cm. high. 

 Leaf terete above its opening, about 7-8 cm. long. Stem very wiry, zig-zag ; stem-bracts 

 2, situated at points of flexion. Flowers small, yellow, 1 or 2, opening on hot days.

 about 4i mm. high, not hooded, widely winged ; the wings only very slightly produced 

 at the sides into rounded dentate lobes ; the intermediate lobe slightly notched and 

 rather higher than the lateral lobes ; all very much shorter than the anther. Anther 

 situated entirely above the stigma, apex produced into a large oblong fleshy downy 

 process greatly exceeding the lobes of the wings. Pollinia 4 fin 2 pairs), directly connected 

 with the viscid disk. Stigma somewhat rectangular.
