Arachnanthe.] CXLVIII. ORCHIDE/E. (J. "D. Hooker.) 29 



Stem 4-6 ft., as thick as a swan's quill, sheaths smooth. Leaves 4-7 in., 

 loriform or linear-oblong, tip narrowly notched. Panicle 2-3 fc. ; branches very 

 short, divaricate, 2-3-fld. ; pedicel with ovary 1 in.; flowers 3-4 in. diam., dark 

 green or yellow barred with maroon ; upper margin of side lobas recurved ; anther 

 broad, truncate; pollinia very large, flattened; strap broad with a median ridge. 



53. PXX&X.JENOPSIS, Blume. 



Epiphytes ; stem short, leafy ; pseudobulb 0. Leaves distichous, coria- 

 ceous. Scape lateral; flowers usually large, loosely racerned. Sepals 

 widely spreading. Petals narrower or broader. Lip clawed or sessile, 

 adnate to the base or foot of the column, side lobes erect, midlobe various, 

 spurO; disk variously appendaged, with usually a forked plate or callus. 

 Column suberect, foot long short or ; anther 2-celled ; pollinia 2, sulcate 

 or 2-partite, strap linear or spathulate, gland large or small. Species 

 about 25, Indian and Malayan. 



The genus requires revision, and a careful examination of the lip, which is very 

 imperfectly figured and described by the authors who have had access to living 

 specimens. The beautiful P. amabilis has been sent from Singapore, where it is 

 cultivated. 



* Lateral sepals inserted by a narrow base to the base or very short 

 foot of the column.

PERAK (Ic. Scortechini). SINGAPORE (fid. Warner I. c.) DISTRIB. Sumatra. 



Leaves 4-10 in., elliptic or oblanceolate, acute. Scape very stout, 1-7-fld. ; 

 bracts ovate, acute ; lateral sepals oblong-lanceolate, unequal-sided, acute, deflexed ; 

 petals smaller, oblanceolate ; lip narrow, incurved, broadly clawed or stipitate ; side 

 lobes erect, narrow, linear, truncate ; midlobe cuneately obovate, apex triangular 

 acute crenulate, disk with a bicuspidate appendage at the base ; column rather long. 

 Colours of flower apparently very variable ; Scortechini describes the sepals and 

 petals as deep carnation with green tips, the side lobes of lip yellow dotted with 

 purple, the midlobe purple ; Warner's figure has a very short scape, few flowers, a 

 violet lateral sepal with cream-cold. inner margins, cream-cold, dorsal sepals and petals, 

 and a violet lip. According to Reichenbach the raceme is sometimes branched. 

 Perhaps two species are confounded under violacea.
