2. HABENARIA GENICULATA, Don Prodr., 25. 
Height of plant 12 to 30 in. Zubers ellipsoid, pubescent. Lower part of зет 
sheathed, middle part leafy, upper part bracteate. Leaves oblong-elliptic, acute, 5- to 
7-nerved, the base narrowed into a long tubular sheath; length 2 to 4'5 in.; the bracts 
lanceolate, acuminate, becoming narrower upwards, 1:5 to 1 in. long. Spike 2 to 4 
in. long, rather laxly-flowered. Flowers ‘8 to 1 in. across; floral bract lanceolate, 
acuminate, as long as the shortly beaked fusiform ribbed ovary. Sepals sub-equal, broadly 
ovate, acute, spreading, the lateral pair sub-erect, Petals narrowly oblong, sub-acute, 
curved inwards, shorter than the sepals. Lip as long as the sepals, variable in breadth, 
sub-orbicular or broadly obcordate, with large cuneate or rounded, fimbriate or 
crenate side lobes, and a small, much shorter, oblong entire apical lobe ; spur infundi- 
buliform at the base, slender, laterally compressed, geniculate, sub-clavate below the 
knee, longer than the shortly-stalked beaked ovary. Anther-cells broad, distant, divari- 
cate, their tubes elongated and curved inwards. Staminodes sub-globular, tuberculate, 
situated on the sides of the anther. Pollinia two, broadly ovate in general outline, 
compressed, each consisting of two thin granular plates attached to a stout incurved 
caudicle triquetous above and tapering to the small hemispherie gland. Stigmas two, 
sub-cylindric-clavate, faleate, rather blunt, the entrance to the spur lying between 
their bases; infertile stigma forming a low broad fleshy arch between the anther-cells, 
Capsule shortly pedicelled, fusiform, ribbed, the apex beaked, 1 in. long. Lindl. Gen.
