796 CXLVIII. ORCHIDE^. (J. D. Hooker.) [Eria. 



41. E. Eriopsidobulbon, Par. Sf Reichb. f. in Trans. Linn. Soc. 

 xxx. 148; leaves 2-3 narrow, spike short puberulous, braets equalling the 

 very small glabrous flowers, lateral sepals ovate-lanceolate obtuse and 

 linear-oblong acute petals 3-nerved, mentum short incurved, lip obovate 

 with 2 thickened arched ridges on the disk, side lobes above the middle, 

 midlobe small semicircular 5 -ridged, column long. 



TENASSERIM ; at Moulmein, P-arish. 



Pseudobulbs 2 in., oblong or ovoid. Leaves 4-6 in., linear-lanceolate, nerves 

 slender. Spike 2 in. j nerves of sepals and petals quite simple. 



Flowers pedicelled. 



a. Bracts large, lanceolate or ovate-oblong. 



42. E. confusa, HooJc.f. Ic. Plant, t. 1850; pseudobulbs elongating 

 into cylindric stems, leaves 2-8 narrow rigid strongly nerved, racemes 

 lateral tomentose, bracts large lanceolate pubescent, sepals -f in. broadly 

 ovate-oblong obtuse 5-nerved pubescent, mentum broadly conic, petals 

 elliptic-lanceolate 3-5-nerved, lip broadly obovate, side lobes incurved 

 with 3 thick middle ridges, midlobe orbicular or ovate thickened, column 

 rather long. E. excavata, in part, Lindl. Gen. & Sp. Orchid. 67. and in 

 Wall. Cat. 1974. 



NEPAL, Wallich. SIKEIM, alt. 4-6000 ft., J. D. H., &c. (E. alba). 



Pseudobulbs 2-4-nodal, lengthening into terete striate stems 3-10 in. long, and 

 as thick as the finger. Leaves lanceolate. Racemes 2-4 in., inclined ; flowers 

 white, lip yellow ; pedicel with ovary f-1 in. ; bracts % in. ; nerves of perianth not 

 branching. Near IE. bractescens, differing in the stiff narrow leaves and bracts. A 

 drawing of it in Herb. Calcutt. shows no ridges on the side lobes of the lip, but 2 

 small spots on the disk and a mesial crest on the yellow midlobe. 



43. E. acervata, Lindl. in Journ. Hort. Soc. 1851, 57, with woodcut', 

 and in Paxt. Fl. G-ard. i. 170 ; pseudobulbs crowded, leaves 3-5 oblanceo- 

 late flaccid, racemes and flowers glabrous, scape interfoliar, bracts lan- 

 ceolate, lateral sepals ovate-lanceolate acuminate 5-7-nerved, petals 

 linear-oblong or -lanceolate 5-nerved, mentum rounded or broadly conic, lip 

 oblong or obovate with 3 median ridges, side lobes about the middle in* 

 curved, midlobe ovate or orbicular, column very short. Eeichb.f. in Gard. 

 Chron. 1878, 106; Hook.f. Ic. PI. t. 1849; Walp. Ann. vi. 269. Dendro- 

 bium seriatum, Wall. mss. 



SIKKIM HIMALAYA (Ic. in Hort. Bot. Calc.). KHASIA HILLS, alt. 4-5000 ft., 

 J. D. H. Sf T.T. ? TENASSERIM, Parish. 



Pseudobulbs 1-2 in., ellipsoid, grooved or flask-like and flattened if too crowded, 

 not lengthening into long stems. Leaves 4-8 in., obtuse or acute, pale green, many- 

 nerved. "Racemes 2-3 in., slender ; pedicels with ovary f-1 in. ; bracts half as long; 

 flower broad, white or yellowish, membranous. The texture of the leaves is 

 peculiar. In Herb. Calcutt. is a drawing of a Sikkim plant which I take to be a 

 form of this with a more conical incurved mentum. Parish's Tenasserim plant has 

 short broad leaves of a different texture. 



44. E. bractescens, Lindl. in Bot. Peg. 1841, Misc. 18 ; 1844, t. 29 ; 

 leaves 2-3 oblong, racemes slender and long-pedicelled white flowers 

 glabrous or puberulous, bracts large, lateral sepals |-g-iu. ovate-lanceolate 

 acuminate falcate and linear-oblong petals 5-nerved, mentum conical sub- 

 acute, hypochile cuneate-obovate with 3 thickened ridges, the lateral short, 

 side lobes pink rounded, midlobe quadrate. Walp. Itep. vi, 277.
