clothed with closely-fitting shoaths. Zeaves disti-ibuted over the upper two-tkirds of
the stem, mcmhranons, oblong-lanceolate or ovate-lanceolate, acute, the edges undulate,
the base usually broad (rarely narrowed) amplcxicaul or sheathing, sessile; length 3
to 8 in., breadth 1-25 to 2-75 in.; the pai-t of the stem above the leaves and below
the raceme with lanceolate acuminate bract-like leaves much smaller than those of the
middle-stem. Máceme 4 to 9 .in. long, crowded.. J'lowers .s.ho\it 1 in. in diam.;
Iraci lanceolate, acuminate, about as long as the slender stalked ovary. Sepals subequal,
oblong-lanceolate, acuminate, spreading or reflexed. Peíais shorter than the
sepals, linear, produced as a wing downwards a Httle below the point of insertion
Zij) as long as the petals, Iiastately 3-partite; the segments narrow, fleshy, the centml
segment horizontal, the hasal pail' sometimes as long as the eentral, but usually shorter;
spw as long as the stalked OTary, slender, vertically compressed, 2-iidged, up-tnrned.
CoUmn stout. Antlicr-cdh .rather . distant, .parallel, narrojv, erect, their tubes long;
poJüma oblong, their candieles slender and twice as long as themselves, the glands minute.
Sfaminodes ovate, ragulose, situated externally to the anther-cell and stigma on each
side. Siiffnm two, oblong, with slightly divergent blnnt apices, situated below the
anthers and at the margins of the month of the spur. Capsule huear-oblong. Hook,
