138 CXLVIII. ORCHIDEA (J. D. Hooker.) [Habenaria. 



cells rather divergent, tubes short, glands of pollinia small ; stigmatic processes 

 elongate, tips often falcate dilated, and upcurved ; rostellum obscure. Capsule fin., 

 sessile, fusiform, ribs thick. Black when dry. 



17. H. arietina, Hook, f. ; habit and foliage of H. pectinata, but 

 petals pubescent broader than the dorsal sepals gibbously dilated on the 

 outer (lower) margin, spur rather longer than the ovaiy. H. pectinata, 

 Lindl. Gen. # Sp. Orchid. 341 ; Wall. Cat. 7029 B in part, and 0. 



TEMPERATE HIMALAYA ; from Simla eastwards, alt. 5-8000 ft. and to 10,000 ft. 

 in Sikkim. KHASIA HILLS, alt. 5-6000 ft. 



So similar in a dried state to IT. pectinata as to be with difficulty distinguish- 

 able, and though separated by Lindley, perhaps only a variety. Unfortunately 

 Lindley in describing both species gave Don's name to the wrong plant, as I have 

 proved by examining Smith's original specimen of O. pectinata in his Herbarium at 

 the Linnean Society, which is of a very small state. Black when dry. 



18. H. intermedia* Don. Prodr. 24 ; leaves ovate or oblong acumi- 

 nate, flowers few very large, dorsal sepal recurved, lateral reflexed narrower 

 than the dimidiate obovate falcate glabrous petals, lip longer than the 

 sepals, spur twice as long as the ovary. Lindl. Gen. & Sp. Orchid. 322 ; 

 Wall. Cat. 7030 ; Reichb. f. in G-ard. Chron. 1879, 136. 



TEMPERATE HIMALAYA ; from Kashmir to Sikkim, alt. 5-7000 ft. 



Stem 810 in. Leaves 2-4 in., scattered, 5 7-nerved, base rounded or cordate. 

 Racemes few-fld. ; bracts broad, equalling the ovary ; flowers 2 in. diam., white or 

 greenish ; lateral sepals falcately lanceolate, acuminate, reflexed, 5-nerved ; petals 

 strongly 5-nerved; spur very stout; anther-cells with long erect filiform tubes, 

 glands of pollinia small ; stigmatic processes long, slender, incurved ; rostellum adnate 

 to the face of the column between the anther-cells. Capsule 1^-2 in., pedicelled, 

 fusiform, beaked, terete. 



19. H. trichosantha, Wall. Cat. 7028 ; leaves ovate-oblong or lan- 

 ceolate, spike lax-fid., bracts shorter than the long-decurved narrow ovary, 

 lateral sepals ovate-oblong or -lanceolate acuminate puberulous, petals 

 linear falcate acuminate, lip longer than the sepals, side lobes capillaceo- 

 multifid, spur longer than the ovary. 



BURMA, at Taongdong, Wallich Moulmein, Parish ; Attran, Brandis (in 

 Serb. Calcutt.~). 



Stem 8-18 in. Leaves few, 3-6 in., 5-7-nerved. Raceme 4-10-fld. ; ovary 1 in, 

 sessile; lateral sepals in., deflexed ; petals dilated upwards, entire or serrulate, 

 1-nerved ; spur 1* in.; anther-cells short, with short free tubes, polliuia much 

 shorter than their caudicles, glands small; stigmatic processes short, globose; rostel- 

 lum an obscure plate between the anther-cells, Capsule 1 in., fusiform, shortly 

 beaked, deeply channelled. 



** Side lobes of lip petaloid, outer margins entire, toothed, or fimbriate, 

 midlobe narrow. 



f Lip deeply 3-lobed or -partite, not or hardly longer than the lateral 

 sepals. 



20. H. greniculata, Don Prodr. 25; stem tall leafy with many 

 slender sheaths above, lateral sepals acute, petals linear- oblong, lip sub- 

 orbicular, side lobes cuneate or rounded fimbriate or crenate, spur longer 

 than the beaked ovary geniculate. Platanthera geniculata, Lindl. in Wall.
