lax-fld. ; bracts minute, truncate, membranous ; pedicel with ovary i in. ; sepals as 

 long, lanceolate, 5-nerved j petals narrower, 3-uerved ; lip ' nearly as long as the 

 sepals, broadly ovate, finely acuminate, cymbiform, quite entire; spur as long as the 

 sepals, suberect, slightly clavate j anther firmly attached by a point to the column. 

 Capsule f in., pedicelled, narrowly ellipsoid, ribs slender. — I have seen only indif- 

 ferent specimens, from which the pollen was gone. Dr. Trimen informs me that it 

 is found in several parts of Ceylon.

Epiphytes ; pseudobulbs clustered, 1-3-leaved. Leaves flat, linear, not 

 plaited. Scape from the base of the bulb, slender, simple or bi*anched ; 

 raceme lax-fld. ; bracts small acute. Sepals narrow, spathulately obovate, 

 obtuse, dorsal arched, lateral connate placed under the lip. Lip adnate to 

 the column above its middle, spreading, more or less 3-lobed, disk with 2 

 short erect lamellae on the mesial line. Column incurved with 2 styliform 

 horizontal or decurved processes on each side of the stigma, and a cucnl- 

 late top concealing the anther ; rostellum suberect, acute ; anther membra- 

 nous, 2-celled; pollinia 2 or 4 in 2 pairs, narrowly pyriform attached by a 

 strap to a small gland. — Species 5 or 6, Indian and Malayan. 



In Herb. Calcutta is a tine drawing of what may be a, new species from 

 Moulmein, with a large quadrate clawed pubescent lip ; it may be intended for 

 A. javanica. 



1. A. javanica^ Beinwdt. in Flora lAterat. 1825, ii. 4 ; in Syllog. 

 Batisb. 1828 ; side lobes of lip broad rounded or subtriangular, midlobe 

 very small clawed oblong concave, claw lamellate. Blume'Bijdr. 377; 

 Limdl. Gen. & Sp. Orchid. 140 ; Walp. Anm. vi. 492. A. picta, Lvndl. in

Tbnassebim, PaHsh. Pbbak, Scorteehmi, and Singapobe, WalUak, &c. 

 Malacca, Griffith, MaAngay. ^-T>ist^13. Java, Philippines. - 



Psevdobulbs f-li in., oblong or ovoid. Leaves 4-6 by J-J in., 2-dentate. Scape 

 6-18 in., simple or branched; pedicels ^ in., capillary; sepals ^-^ in., white with 

 purple tip and central broad or narrow band ; petals subsimilar ; lip white with a 

 purple band and lamella. Capsule \ in., broadly ellipsoid. — It is difficult to reconcile 

 GrifSth's figure with the above description of the lip, but his habitat being that of 

 Maingay's plant (Orchard trees, Malacca) seems to identify it. 



2. A. indica, Wight. Ic. t. 1748 (bad) ; lip oblong subpanduriform 

 tip rounded, lamellae opposite the contraction. Walp. Ann. vi. 492. 



Tenassbeim, Griffith (in Serb. Lindl.), Parish. PjeafANG, Mai<ngay. 



A much smaller plant than A. javanica, with more densely tufted pseudobulbs, 

 very narrow leaves, scapes shorter, more branched, and smaller flowers ; the sepals are 

 i in. long and the very different lip is inserted higher up, just under the column. — 

 Wight who had lost the locality of the species he figured probably received it 

 from GrifEth. In a drawing by Parish the fiowers lare yellow green faintly blotched 

 with purple. Wight's figure of the lip is quite unlike that of the specimen he 

 depicted, which is now in Herb. Kew. 



3. A. Ztldleyi, Hook. f. ; lip with small oblong obtuse side lobes and 

 a large orbicular or transversely oblong clawed smooth midlobe, lamell» 

 on the claw.
