Hal)snaria.~\ CXLVIII. ORCHIDE^:. (J. D. Hooker.) 165 



bracts foliaceous, broadly ovate, l|-2 in. long, cymbiform, acuminate ; ovary in. 

 long, erect, slender, beaked, narrowly winged; sepals erect, in., ovate-oblong, 

 obtuse, concave ; petals erect, as long, linear, obtuse ; lip as long as the sepals, very 

 coriaceous, triplicate in bud, being folded longitudinally down the middle, with the 

 side lobes appressed to the midlobe, and each also folded down the middle with the 

 concavity inwards, long clawed, cuneately obovate, obtuse, claw geniculate ; side lobes 

 linear-oblong, obtuse, incurved, shorter than the triangular ovate midlobe ; spur 

 pendulous, subclavate ; anther broad, bases of cells shortly upcurved ; pollinia large, 

 pyriform, grains large, caudicles short, glands small orbicular. The stigmatic pro- 

 cesses differ from those of any other Indian Habenaria, A. Richard figures them 

 as clavate as in most Habenaria;, but I have never found them so, though I have 

 examined many flowers. The rostellum ? forms a broad triangular acute plate 

 extending across the column, and reaching to the bases of the anther-cells.

Hoot unknown. Stem very slender, recurved, with the raceme 4-6 in. high. 

 Leaves one large (2-4 in.) subradical, elliptic-lanceolate, acute, and several small 

 scattered ones alternate higher up, all membranous, 5-7-nerved. Racemes 2-3 in., 

 decurved ; flowers secund, -^-i in. diam., very shortly pedicelled ; bracts ovate or 

 lanceolate, as long as the short ovary; sepals white and rosy; petals 1-nerved ; lip 

 recurved, lanceolate, terminal half solid terete acuminate green, spur inflated, nearly 

 as long as the sepals ; anther beaked, cells contiguous, parallel, pollinia oblong, 

 grains large, caudicles very short.

Tubers globose, small. Stem 3-5 in., erect or recurved. Leaves 2-5 in., linear, 

 acuminate, sides complicate, bases sheathing. Spike 1-2 in., more or less recurved, 

 dense-fld.; flowers secund, pink; bracts linear-lanceolate, lower -i-f in. longer than 

 the flowers ; ovary A in., curved ; sepals lanceolate, 1-nerved ; petals much narrower, 

 acuminate ; lip as long as the sepals, sessile, linear-oblong, trifid to about the middle, 

 puberulous, strongly-nerved, lobes parallel, lanceolate, acuminate ; spur nearly as 

 long as the sepals, conoidal, slightly contracted at the base, inflated, apex subacute j 

 anther membranous ; polliuia clavate, grains very large, caudicles short, glands large, 

 cordate, membranous. The resemblance to H. urceolata is remarkable ; lobes of the 

 rostellum inflected over the glands of the pollinia like two flaps or doors, whence the 

 name.
