Tropidia.~\ CXLVIII. OROHIDE^. (J. D. Hooker.) 93 



stout ; lip nearly as long as the petals, obtuse, lateral nerves narrowly lamellate 

 below the middle ; column with a long slender rostellum ; anther narrowly lanceo- 

 late; pollinia clavate, grains lamelliform, caudicle long slender, gland minute. 

 I have examined Lindley's specimen of T. semilibera, and find that he was in 

 error in supposing that the lateral sepals are free to below the middle; it does 

 not differ from T. angulosa. 



Sect. II. TROPIDIA PROPEE,. Lip cymbiform, not spurred. 

 * Flowers in short sessile axillary or axillary and terminal spikes. 



2. T. cureulig-oidesj Lindl. in Wall. Gat. 7386 A; Gen. & Sp. 

 Orchid. 497; bracts ovate acuminate, lip with a reflexed tip a thickened 

 midnerve and intramarginal ridges from beyond the middle to the base 

 of the reflexed tip. T. assamica, Slume Orchid. Archip. Ind. 124, t. 41, 

 f. 2.

 ?PERAK, Wray. 



Stem 1-2 ft. Leaves 6-10 by 1-1-j in., elliptic- or linear-lanceolate, caudate- 

 acuminate, 5-nerved. Spikes -f in., erect or decurved ; bracts imbricate, in., 

 ovate-lanceolate, upper narrower ; sepals ^ in. long, strongly 5-ner^ed, dorsal 

 linear-lanceolate, lateral strongly recurved, lanceolate from an ovate base, taper- 

 pointed; petals rather shorter, obliquely ovate-oblong, obtuse, 5-nerved; lip much 

 shorter than the sepals. Capsule f in. long. Bentham in Flora of Hong Kong has 

 referred Schauer's Ptychochilus septemnervis of China to this, but according to 

 Schauer's figure it differs in the much smaller flowers with ovate acute sepals, and 

 a lip without the reflexed tip. Wallich's 7386 B from Burma is a different species, 

 but in too imperfect a state for analysis. 



3. T- graminea? Blume Orchid. Archip. Ind. 124, t. 41 ; leaves 

 lanceolate strongly 3-5-nerved, spikes very small and few-fld., lip obtuse 

 with short intramarginal lamellae towards the middle, tip shortly recurved.

MALAY PENINSULA; on Mount Ophir, Griffith, Loll. DISTRIB. Java. 



Stem 18 in., slender. Leaves 6-8 by 1-1 in., acuminate as in- C. circuligoides. 

 Spikes i in. long, 1-2-fld. ; bracts in., about equalling the ovary ; flowers in. 

 long, strongly recurved ; sepals lanceolate, acuminate, 3-nerved ; petals falcately 

 gibbously lanceolate, 1-2-nerved ; lip ovate, subacute, margins undulate towards the 

 apex tip recurved. Described from a single specimen. Blame's figure represents 

 the leaves shorter and broader, and the spikes as with rather more flowers and 

 terminal only. 



** Flowers in peduncled spikes. 



4. T* Main gray i? Hook, f, ; spikes terminal and axillary, bracts 

 subulate, lip with a median and intramarginal lamellae extending from the 

 base nearly to the acute tip. 



MALAY PENINSULA; on Mount Ophir, Maingay. 



Stem 12-18 in. Leaves 4-6 by f-1 in., elliptic-lanceolate, acuminate, 5-nerved. 

 Peduncle 1^-2 in., flexuous, sheathed ; spike short ; bracts very variable, lower 

 1 in., upper smaller; flowers in. long; sepals oblong-ovate, subacute, lateral 

 5-nerved, dorsal narrow; petals obliquely oblong, 3-4-nerved ; lip with no reflexed 

 tip. Very like T. pedunculata, Blume, of Sumatra, but the flowers are not fur- 

 furaceous, the sepals are 5-nerved, and the intramarginal lamellae of the lip are 

 continuous.
