Vrydagzynea.'] cxlviii. orohidb^. (J. D. Hooker.) 97 



sheaths membranous ; flowers i in. long, pale yellow and pink; blade of lip as long 

 as the oblong inflated spur, margins incurved. — Only one specimen seen. 



2. V. albida, Blume Orchid. Archip. Ind. 75, t. 19, f. 2, 3; bracts 

 oblong subacute, lip oblong retuse with a short obtuse tooth, disk with a 

 low hispidulous ridge from the base to beyond the middle. Etseria albida, 

 Blume Bijdr. 410; Lindl. Gen. & Sp. Orchid. 491. 



Peeak ; in the Padang Valley, Wray. — Disteib. Javp. 



Whole plant 8-10 in. high, glabrous. Leaves 1^-2 in. long, ovate or elliptic, 

 subacute. Scape slender, 1-3 in. ; sheaths broadly acuminate, membranous ; spike 

 very many-fld. ; bracts J in. long, exceeding the pale green flowers ; sepals i in. 

 long, obtuse ; blade of lip as long as the inflated spur. Capsule i in. long. — The 

 specimen as in fruit, but the withered flowers are well preserved. A drawing appa- 

 rently of this by Scortechini represents the leaves as more lanceolate with waved 

 margins. 



3. V. gracilis, Blume Orchid. Archip. Ind. 72, t. 17, and t. 20, f. 1 ; 



bracts lanceolate acuminate, lip oblong, tip rounded apiculate, disk with a 

 slender ridge from base to apex. 



Peeak ; at Horum, Scortechini. — Disteib. Sumatra. 



Whole plant 3-8 in. high, simple or branched, glabrous. Leaves |-1 in., petioled, 

 ovate or ovate-cordate, subacute. Scape very short ; spike few-fld., papillose ; sepals 

 •|- in. long, acute, agglutinate to the narrow petals ; spur obtuse, nearly as long as the 

 blade of the lip; anther with a membranous tip. 



82. CVSTORCKXS, Blume. 



Characters of Vrydagzynea, but lip clawed as in Zeuxine, and with a 

 large exposed didymous sac. — Species 3 or 4, Malayan. 



.^theria fusca, Lindl., referred here by Bentham, is a, true OooAyera, with the 

 shallow sac of the lip partially exposed. It must be by oversight that its habit is 

 described as altogether that of Cystorohis, from which it differs in its tufted roots, 

 radical leaves, robust habit, and alpine habitat. Amongst Scortechini's drawings of 

 Perak Orchids there are several probably referable to Cystorchis, but unaccompanied 

 with specimens. 



1. C. javanica, Blume Orchid. Archip. Ind. 87, t. 24, f. 1 ; leaves 

 dark green with crenate pinkish margins, lip with a long straight claw and 

 dilated tip. Etseria javanioa, Blume Bijdr. 410 ; lAndl. Gen. Sf Sp. 

 Orchid. 491 (^theria). 



Perak, Scortechini. — Disteib. Java. 



Stem a span long, leafy above. Leaves f— li in., petioled, ovate, obtuse or subacute, 

 margins entire or crenulate. Scape and short raceme puberulous ; sheaths lanceolate, 

 acuminate ; bracts equalling the ovary ; flowers J in. long ; lateral sepals ovate- 

 lanceolate, 1 -nerved, puberulous; petals linear-oblong, obtuse, 1-nerved ; sac of lip 

 membranous, claw rigid grooved, the margins being inflexed ; rostelluiii ovate ; 

 anther sessile, very convex, umbonate ; gland of poUinia ovate, acute. — Specimen 

 not good, but I think referable to Blurne's plant, of which the leaves are described 

 as undulate, dark purple above and pale flesh coloured beneath. 



2. C> variegrata, Blume Orchid. Archip. Ind. 89, t. 24, f. 3, and 36 ; 

 leaves pale green with dark transverse bands, scape slendei-, raceme 

 puberulous, beak of lip with incurved sides and a small dilated tip.
