24 OXLVUI. ORCHIDEJ:, (,T. D. Hooker.) [Luisia. 



Stem 2-5 in. ; internodes -$ in. Leaves as thick as a sparrow quill. Rachis 

 of spike clothed with imbricate ovate acute bracts ; pedicels decurved j flowers 

 punctulate ; dorsals sepal oblong obtuse and similar petals 1-nerved ; lip as long as 

 the sepals, epichile about half as long as the hypochile both concave. Griffiths' 

 specimens are not in flower but appear to be the same as Mann's, which are so. 



6. Xi. primulina, Par. & Reichb.f. in Trans. Linn. Soc. xxx. 144, 

 t. 30, f. 1 ; stem short very stout, leaves 3-4 in. very stout, rachis short 

 few-fld., sepals subequal oblong acute, petals larger obovate-spathulate 

 obtuse, lip much longer than the lateral sepals yellow, hypochile small 

 short saddle-shaped, epichile large triangular-ovate obtuse, margin 

 obscurely lobulate. 



TENASSERIM ; at Moulmein, Parish. 



$tera 3-4 in. ; internodes short. Leaves \ in. diam. Flowers f in. diam., pale 

 yellow with a purple column. Described chiefly from a drawing by Parish. A draw- 

 ing in Herb. Calcutt. of apparently the same species (collected at Moolyet, Moulmein) 

 has elliptic^acute sepals, a shorter cordate epichile, a larger hypochile with a purple 

 disk, and a yellow column j its concave lateral sepals are spurred at the back. There 

 are in Herb. Kew flowers and leaf of a cultivated plant from Burma (Hort. Kew), 

 resembling this, but with a purple lip. 



7. Xi. macrotis, Reichb. f. in Gar A. Chron. 1809,1110; habit and 

 leaves of L. Psyche, sepals triangular keeled, petals longer triangular 

 ligulate acute flat base broad, lip much longer than the sepals violet-black 

 triangular-ovate from a broad 2-auricled base sulcate. 



ASSAM (Sort. Day}. 



I have seen only flowers of what I take to be this (Hort. Kew), in whiich the 

 sepals are ovate-oblong, subacute, the petals much longer (^ in. long), linear-oblong, 

 obtuse, and the lip very like that of L. primulina, and of the same size, but dark 

 purple. The shape of the petals distinguishes it from primulina. 



** Petals much longer than the sepals. 



8. Xi. Psyche, Reichb. f. in Sot. Zeit. 1863, 98; in Gard. Chron. 

 1865, 342 ; stem tall stout, leaves 3-5 in. stout, rachis short, flowers few 

 large, petals linear- sp at hulate or obovate obtuse twice as long as the obtuse 

 concave sepals, lip broadly ovate-obloiig retuse, base contracted saccate 

 2-auricled. Sot. Mag. t. 5558. 



TENASSERIM ; at Moulmein, Parish. ? KHASIA HILLS, alt. 3000 ft., Mann. 



Stem 1 ft., internodes 1 in. Leaves strict, in. diam. Sepals % in. long, 

 petals 1^ in., variable in breadth, both pale greenish yellow. Lip convex, nearly 

 1 in. long, violet-brown, tessellated with white or yellow, auricles erect, embracing 

 the white column. Capsule 1^-2 in. long. Mann's specimen is in fruit only. It 

 has a large clavate capsule as figured by Parish in his drawing of L. Psyche.

 slender, leaves 4-7 in., rachis in., flowers few large, petals narrow twice

 convex base broad 2-auricled, lip with V divergent lobes. Lindl. Fol.
