separated from it by a deep cleft, the glands of the pollinia close 
together; anther horizontal; ovary 3} lines long.

The flowers have a dull yellow ground, the galea marked by definite 
purple lines ; the sepals with purple spots; the lip purple, with a yellow 
apex and base. The galea resembles in shape that of D. maculata, 
Linn. f. (otherwise a very different plant), or that of some of the very 
shortly-saccate Satyria. The early closing of the flowers by the 
falling inwards of the lip, and the erection of the side-sepals is very 
curious, and I have not observed it in any other species. It is most 
nearly allied to D. neglecta, Sonder, which has flowers of only half the 
size, but which has not hitherto been detected on the Peninsula.

(1781), p. 406.—Glabrous, erect, 15-30 in. high; stem nearly straight, 
slender, distantly clothed with closely-wrapping sheaths, with shortly- 
spreading points; leaves 4-6, radical, linear-lanceolate, acuminate, 
laxly spreading; raceme distantly 4-9-flowered, subsecund; bracts 
broadly ovate, acute, erect, about as long as the ovary; side-sepals 
broadly elliptical, obtuse, mucronulate below the apex, spreading, 
about 10 lines long, 7-8 lines wide; odd sepal ovate, concave, obtuse, 
bluntly and widely saccate behind, just below the middle, about 9 lines 
long, 5 lines in depth; petals obliquely oblong, apex incurved, posterior 
margin erosulate, meeting and arching over the anther, adnate to the 
column at base; lip linear, acute, 5 lines long; column erect or 
ascending ; rostellum with divaricate arms, bearing the glands at the 
apices, furnished posteriorly with a petaloid appendage reaching half- 
way up and closely embracing the anther; glands facing the front of 
the flower. Bot. Mag. (1888), t. 7021; Satyrium secundum, Thunberg,
