Habenaria.] GXLVIII. OROHIDE^E. (J. D. Hooker.) 159 



f Stem leafy, leaves scattered or subimbricate. 



85. H. breviloba, Hook.f. ; slender, leaves oblong-lanceolate acumi- 

 nate, spike short dense-fld., bracts about equalling the ovary, lateral sepals 

 lanceolate, petals broadly oblong, lip as long as the sepals obcordate sub- 

 flabelliform, spur minute inflated incurved. Peri stylus brevilobus, Thwaites 

 JEnum. 311. 



CEXLON ; near Ratnapoora, Thivaites. 



Stem with spike 10-18 in., naked below. Leaves 2-3 by f-f in., bases sheathing, 

 nerves very slender. Spike (young) 1 in. ; bracts lanceolate, finely acuminate ; 

 ovary in. ; lateral sepals linear-lanceolate, subacute, 1-nerved ; petals oblong, 

 obtuse, 3-nerved ; lip sessile at the base of the column ; anther oblong, truncate, 

 cells parallel, tubes ; stigmatic processes ; rostellum 3-fid, concealing; the small 

 poll iuiar glands. A very anomalous species, the flowers are too young for satis- 

 factory analysis. Thwaites describes the lip as having a minute midiobe. 



86. H. malabarica, Hook. /. ; stem leafy, leaves many ovate or 

 lanceolate acuminate upper passing into bracts longer than the flowers, 

 spikes many-fld., ovary very short, lateral sepals linear, petals obliquely 

 ovate-oblong obtuse, lip as long as the sepals deeply trifid, lateral seg- 

 ments subulate recurved, mid one straight, spur a small globose didymous 

 or ellipsoid sac. Peristylus brachyphyllus, A. Rich, in Ann. Sc. Nat. Ser. 

 2, xv. 70, t. 2 A. 



NILOHIRI, and Bababudan Hills in CANAKA, Heyne, Perrottet, Stocks. 



Stem, rather stout, 6-12 in. Leaves 1-2| in., bases sheathing, nerves very 

 slender. Spike 2-4 in., rather dense-fld. ; bracts herbaceous, lower -i-f in. or 

 longer, often twice as long as the flowers, ovate-lanceolate, acuminate, sheathing ; 

 ovary in. ; lateral sepals as loug, erect or spreading, 1-nerved, apiculate below the 

 tip, dorsal elliptic obtuse faintly 3-nerved ; base of lip 3-lobed above the concave 

 claw, contracted at the base of the segments ; spur incurved or not ; anther-cells 

 parallel, glands of pollinia concealed by the 3-fid rostellum j stigmatic processes 

 clavate. Habit of H. peristyloides & concinna. 



87. H. torta ? HooJc. /. ; small, slender, subbasal leaves linear-lanceo- 

 late upper passing into narrow sheaths, spike very slender lax-fld. twisted, 

 bracts longer than the very small secund flowers, lateral sepals linear 

 obtuse, petals linear-oblong, lip equalling the sepals 3-cleft beyond the 

 middle, lobes short obtuse lateral spreading or incurved midiobe straight, 

 spur a minute sac. Peristylus spiralis, A. Rich, in Ann. Sc. Nat. Ser. 2, 

 xv. 69, t. 2 B ; Wight Ic. t. 1696. 



On the WESTERN GHATS ; from the Ooncan to Travancore, Wight, fyc. CEYLON, 

 in the Central Province, alt. 4-7000 ft. 



Stem with the spike 6-18 in., often flexuous. Leaves 12^ in., obtuse acute or 

 acuminate, nerveless, passing into the sheaths of the scape. Spike 2-4 in., rachis 

 often flexuous ; bracts %-% in., lanceolate, acuminate ; flowers decurved, greenish 

 white; lateral sepals reflexed, YQ g- in. long, dorsal linear-oblong obtuse; lip very 

 variable, fleshy, broader or narrower than long, base truncate above the short 

 concave claw; anther minute, cells parallel; stigmatic processes clavate; ros- 

 tellum between the cells, 3-tid. The Ceylon plant has larger flowers than the 

 Peninsular. 



88. H. Prainii, Hook. f. ; stem slender naked above or with one or 

 two sheaths, leaves few oblong or ovate-oblong acute, spike many-fld., bracts 

 as long or longer than the ovary, lateral sepals linear-oblong obtuse, petals
