AppendiculaJ] CXLVIII. ORCHIDE^;. (J. D. Hooker.) 85 



PERAK ; on Gunong Batu Pateh, alt. 3-4000 ft., on rocks, King's Collector. 



Stem 12-24 in., stout, terete. Leaves rather thin, base semi-amplexicaul ; sheaths 

 i in. Racemes 3-6 in., terminal and leaf-opposed, sessile or peduncled, erect; rachis 

 stout ; bracts -*- in., oblong, obtuse, coriaceous, recurved, strongly nerved ; flowers 

 i in. long, bright yellow with a red centre ; lateral sepals recurved, acute ; petals 

 obovate-oblong, 3-nerved; column unarmed; anther as broad as long. Capsule 

 | in., fusiform, strongly ribbed, claret-coloured. Very like A. cristata, Blume, of Java, 

 but the limb of the lip is not " rounded emarginate and crested on either side." 



9. A. IVXairm ayi, HooJc.f. Ic. Plant, ined. ; leaves 2-3 by | in. linear- 

 lanceolate tip dilated apiculate, racemes terminal many and dense-fld., 

 bracts spreading and incurved, mentum sub-cylindric or shorter, lip elliptic- 

 or ovate-oblong 5-nerved, base calceolar, tip rounded. 



PERAK, Scorteckini. PENANG, Maingay, (Kew Distrib. 1617). 



Stems 6-16 in., rafher slender or stout, unbranched. Leaves suberect, narrowed at 

 the base, tip minutely 2-fid or rounded. Racemes 1-2 in., simple or branched 

 at the base, suberect, flexuous ; bracts $-% in., deflexed, then incurved, coriaceous, 

 subacute, 5-ribbed ; flowers T L in. long ; lateral sepals broad, obtuse, nerve slender ; 

 petals linear- or obovate-obloug, 3-nerved ; lip concave ; column unarmed, rostellum 

 short, triangular; anther ovate, acuminate. Capsule % in., fusiform. The Perak 

 specimens are more slender than the Penang, the mentum is longer and more 

 cylindric, the petals narrower, 1 -nerved. The species should be compared with 

 A. graminifolia, Teysm. and Binnend. 



IMPERFECTLY KNOWN SPECIES. 



10. A. echinocarpa, Hook. f. Ic. Plant, ined. ; leaves %-% in. close 

 set orbicular-oblong coriaceous margin thickened upper base reflexed, spike 

 short terminal few-fld., bracts orbicular concave, capsule ellipsoid, valves 

 densely clothed with soft bristles. 



PERAK ; lower camp in Gunong Batu Pateh, alt. 3400 ft., Wray. 



Stem 4-6 in., slender but rigid ; internode ^ in. Leaves semi-amplexicaul, pale, 

 opaque, rather waved ; tip rounded, obscurely 2-fid. with incumbent teeth ; upper base 

 usually reflexed, like an ear. Capsule % in. long, turgid. A very remarkable 

 species. 



A. LONQIFOLIA, Slume Sifdr. 304; Lindl. Gen. $ Sp. Orchid. 230? Tlnvaites 

 Enum. 806. CEYLON, Ambagamowa district, rare, Thwaites (C.P. 3208). Of the 

 plant thus doubtfully referred by Thwaites to the Javan A. longifoliu, this author 

 says that the flowers are not in a sumciently perfect state for analysis. Blume thus 

 describes longifolia, " Stems simple compressed, leaves linear-lanceolate retuse, 

 flowers densely capitate." Thwaites adds, "leaves 3-5 by | in., retuse, mucronate." 

 Can the Ceylon plant be an Agrostopliyllum or Phreatia ? 



A. TERES, Griff. Notul. iii. 359 j Ic. Plant. Asiat. t. 332, is Ceratostylis teres, 

 R. f. see v. v. p. 825. 



A. SP., Griff. Notul. 359 ; Ic. Plant. Asiat. 335, fig. 1, analysis only, from 

 Afghanistan, cannot (as Lindley in Hook. Kew Journ. vii. 36 observes) be an 

 Appendicula. 



74 THEXiASXS, Blume. 



Epiphytes, with either small 1-2-leaved pseudobulbs, or with short 

 compressed stems clothed with equitant leaf sheaths. Leaves oblong or 

 linear-oblong flat, or loriform and jointed on the sheath. Scape from the 

 base of the pseud obulb, or lateral on the stem, with 1-3 small sheaths ; 

 flowers very minute, spicate, cellular. Sepals connivent, dorsal flat, lateral 

 concave keeled or winged. Petals narrow, membranous. Lip sessile at the
