SIKKIM HIMALAYA (Ic.in . Hort . Bot. Calc. ) KHASIA HILLS , alt . 4-5000 ft ., J.D.H . & T.T. .? TENASSERIM , Parish .

Pseudobulbs 1-2 in., ellipsoid , grooved or flask-like and flattened if too crowded , not lengthening into long stems . Leaves 4-8 in., obtuse or acute , pale green , many-nerved . Racemes 2-3 in., slender ; pedicels with ovary ¾ -1 in.; bracts half as long ; flower broad , white or yellowish , membranous .- The texture of the leaves is peculiar . In Herb. Calcutt . is a drawing of a Sikkim plant which I take to be a form of this with a more conical incurved mentum . Parish’s Tenasserim plant has short broad leaves of a different texture .
