CXLVIII. ORCHIDE/E. (J. D. Hooker.) 793 



narrow obtuse 3-nerved, dorsal longest, petals linear oblong-ovate obtuse 

 3-nerved, lip entire ovate subpanduriform subacute, side nerves forming a 

 2-arched thickened purple ridge towards the base. Wight Ic. 1635 (E. 

 pubescens on the plate) ; Walp. Ann. vi. 275. 



NILGHIRI HILLS ; on the West slope, Perrottet, Wight. 



Leaves 3-5 in., acute or acuminate. Racemes as long or shorter, very many-fid, j 

 pedicels shorter than the bracts ; flowers yellowish. 



29. E. pubescens, Wight Ic. 1634 (E. polystachya on the plate); 

 pseudobulbs short as thick as the thumb, racemes from amongst the 

 (lanceolate) leaves drooping slightly pubescent, flowers |-| in. long, sepals 

 lanceolate acute 5-7-nerved, dorsal longest, petals linear-lanceolate 5-nerved, 

 lip entire ovate- subcordate acute, side nerves forming arched thickened 

 ridges. Walp. Ann. vi. 275. 



NILGHIEI HILLS ; on the West slope, Wight. 



Readily distinguished from J5. polystachya, by its much larger flowers, nearly 

 glabrous racemes, and 5-7-nerved sepals, which are white with pale streaks ; lip 

 with purple blotches and yellow tip. 



30. E. mysorensis, Lindl. in Journ. Linn. Soc. iii. 54; pseudobulbs 

 short thick, racemes from amongst the (lanceolate) leaves curved glabrous, 

 flowers -| in., sepals lanceolate acute, nerves 3-5 very strong and reticulate, 

 petals lanceolate acute 3-nerved, side nerves branching, lip clawed entire 

 from ovate- to oblong-lanceolate subpanduriform, side nerves usually form- 

 ing arched thickened ridges. 



MALABAE and DHAEWAR ; on the Bababoodan Hills, Law. 



This will probably prove to be a form of E. polystachya. Lindley describes the 

 lip (which is very variable in size, shape, and nervation) as wholly smooth, but though 

 the arched ridges are sometimes slender, they are always present, and often very 

 thick and even crenate. 



31. E. tricolor, Lindl. Gen. fy Sp. Orchid. 65 (not elsewhere) ; pseudo- 

 bulb 4-6 in. columnar, leaves linear, racemes from amongst the linear 

 sessile leaves erect puberulous, flowers -| in. long, sepals lanceolate acute 

 3-nerved, outer nerves branching, petals linear acute 3-nerved, lip entire 

 ovate-lanceolate acute obscurely lobed at the side smooth, claw very large 

 deeply saccate. Thwaites JEnum. 299. 



CEYLON; Central Province, alt. 4-7000 ft., Macrae, &c. 



Eeadily distinguished from mysorensis by the narrow leaves, stout scape and 

 raceme, and by the remarkable sac at the base of the lip, which is constant. 



32. E. ringrens, Reiclib.f. in Bonplandia, v. 222; pseudobulb 5 in. 

 fusiform, leaves linear-lanceolate acuminate, racemes lateral glabrous, 

 bracts ovate much shorter than the pedicels, flowers | in., sepals lanceolate 

 and broadly linear, petals 3-nerved, lip small ovate acute 5-nerved with an 

 oblong thickening on each side below the middle. Walp. Ann. vi. 275. 



TENASSEEIM ; at Moulmein, Parish. 



Pseudobulb as thick as the finger in the middle. Leaves 5-6 in., terminal. 

 Raceme 2-2% in., suberect. Lindley (in Journ. Linn. Soc. iii. 55) refers this to E. 

 ovata, B. R. xxx. (1844) under t. 29, of the Philippines, which has ovate obtuse 

 leaves and a pubescent raceme. 



33. E. obesa, Lindl. in Wall. Cat. 1976; Gen. fy Sp, Orchid. 68; 

 in Sot. Reg. 1844, under t. 29 ; in Journ. Linn. Soc. iii. 53 ; pseudobulbs
