 Leaves 1ft. or more long, linear. Lateral sepals olive-green, 2in. long. Petals 

 with dark claws, the lamina pale-yellow. Labellum middle lobe broadly-rhom- 

 boid, lateral lobes small. Glands at base. Column wings not toothed.

4. I>. aurea (golden), Sm. Exot. Bot. i. 15, t. 9 ; Benth. Fl. Austr. vi. 327. 

 Stems 1ft. high or more. Leaves narrow, not very long. Flowers 2 to 5, 

 yellow or more or less blotched or tinged with brown. Petals obovate-oblong or 

 elliptical, 6 to 8 lines long in the typical form including the claw ; lateral sepals 

 rather longer, more or less dilated above the middle ; dorsal sepal shorter than 

 the petals, broad and embracing the column at its base, the ovate upper portion 

 more open. Labellum as long as the dorsal sepal, divided to the base, the middle 

 lobe very broad, contracted at the base, the lateral lobes much shorter, broadly 

 falcate, often undulate-toothed, the disk with 2 raised longitudinal plates ending 

 usually in small teeth at or below the middle of the lamina. Lateral lobes of the 

 column falcate, obtuse, sometimes irregularly toothed, the wings almost 

 continuous at the base with the raised lines of the labellum. — K. Br. Prod. 315 ;

 or purple and sometimes almost entirely dark-coloured except the yellow centre of 

 the petals, under Jin. long. Dorsal sepal erect rigid and embracing the column 

 at the base, ovate-oblong and very open at the top ; lateral sepals at length 

 recurved, narrow, rarely exceeding the petals ; petals ovate, on a long rigid dark- 

 coloured claw. Labellum shorter than the dorsal sepal 3-lobed from above the 

 base, the lateral lobes large and usually as long or nearly as long as the broad 

 middle lobe, the 2 raised lines of the disk ending usually in prominent angles 

 or teeth a little above the base of the middle lobe. Lateral lobes of the column 

 often toothed.— R. Br. Prod. 315 ; Bot. Mag. t. 8156 ; Lindl. Gen. and Sp. Orch.

 curved, not broad, often somewhat toothed, about J the length of the ovate- 

 rhomboid middle-lobe ; the 2 raised longitudinal lines far apart, ending in 

 pubescent calli at the base of the broad part of the middle lobe, the intervening 

 pubescent centre continued more or less along the middle of the lobe. — Lindl.
