828 CXLVIII. ORCHIDEJE. (J. D. Hooker.) [Trickosma. 



E. coronaria, Reichb. f. in Wulp. Ann. vi. 272, and in Gard. Citron. 1870, 

 234. Coclogyne coronaria, Lindl . in Hot. Reg. 1841, Misc. 83. 



SIKKIM HIMALAYA, alt. 5-6000 ft, and KHASIA HILLS, alt. 4-5000 ft. 



v 3-6 in., from an underground soft rhizome, as thick as a goose-quill, naked, 

 fleshy ; basal sheaths few, lax. Leaves ovate-lanceolate acuminate, thick, 3-nerved. 

 Scape 1-2 in., 2-4-fld. ; bracts large; pedicel with ovary f-1 in.; flowers white, 

 yellowish or purplish, sweet-scented ; latiral sepals $ in. long, ovate-lanceolate; 

 petals oblong ; lip subsessile, ovate-oblong, streaked with purple ; disk yellow, with 

 2 thick crenate ridges between the side lobes, and 7 on the suborbicular midlobe ; 

 anther rather fleshy. 



34. CCDLOGYNE, Lindl. 



Epiphytes ; rhizome creeping ; pseudobulbs 2-(rarely l-)leaved. 

 Leaves coriaceous, or thin and plaited. Scape usually short; flowers 

 usually racemed, .rarely (except in sect. Pleione) 2 or solitary ; bracts 

 long, sheathing, deciduous. Sepals subequal, lateral saccate at the base. 

 Petals narrower. Lip sessile at the base of the column, erect and em- 

 bracing it, base concave or saccate. Column long, erect, winged, foot ; 

 top hooded, membranous ; anther more or less 2-celled ; pollima 4, cohering 

 in pairs by a granular viscus. Species about 70, Indian and Malayan. 



In some species of this genus the flowers are produced from the undeveloped 

 pseudobulbs ; in others only from the fully developed ; and this character is quite 

 constant. Again, in some species which flower from the undeveloped pseudobulbs 

 the sheaths of the flowering scape are closely imbricating, and all coriaceous or 

 membranous ; in others the inner sheaths are more or less fo'.iaceous, or one or two 

 may form fully developed leaves. This character does not so well limit species, but 

 is very useful. Lastly, the presence or absence of sheaths on the scape of the species 

 which flower from the mature pseudobulh, and their position, afford very constant 

 characters. A consideration of these hitherto partially recognized characters suggests 

 the following arrangement of the Indian species. 



Sect. I. EUCCELOGYNE. Flowers and leaves coaetaneous. Lip 3-lobed, the 

 terminal lobe spreading. 



* Flowers from an undeveloped pseud jbulb at the base of the old pseudobulb. 

 Sheaths of the scape all basal. 



f Sheaths of the scape imbricating, none becoming foliaceous (except sometimes 

 in C. suaveolens, occultata, breviscapa & sulfurea). 



Racemes pendulous or decurved, many-fld. (or feiv-jld. in C. cristata). Sp. 1-8. 



Racemes erect or inclined, rarely drooping, many- orfew-fld. Sp. 9-20. 



ff Inner sheaths of the scape more or less foliaceous. (See also C. suaveolens, 

 occultata, breviscapa & sulfurea). Sp. 21-29. 



** Flowers from the top of the mature pseudobulb. 



f Scape sheathed at the base only. Sp. 30-35. 



tt Scape not sheathed either at the base or beneath the raceme. Sp. 3G-38. 



ff*t* Scape with distichous- imbricating sheaths below the raceme only. 

 Sp. 39-47. 



Sect. II. PLKIONE. Flowm appearing before or after the leaves (except 

 C. JLookeriana) from the base of the mature! pseudobulb. Lip large, convolute, 

 with a shovel-shaped mouth, very obscurely 3-lobed. Sp. 48-53. 



Doubtful species. Sp. 54-55.
