surface of the gi-ouud, two or three namicrs, each producing at its extremity a tuber
smallei" than that of the parent. Leif bi'oadly cordate or orbicular, strongly plicate.
Flowers solitary, few or ia racomes, often pendulows. Sep th and petals sub-ccjual, uan'ow,
connivent or spreading. Lip sometimes slightly saccate at the base, adnate to tlie base
of the column, rather narrow, the lower pait couTolute roimd the column ; the lateral
lobes small, usually triangular ; the apical lobe flat, ovate or orbicular, entire or fimbriate.
Column elongate, clavate upwards; the stigma anticous, oblong to orbicular. PoUinia
two or four, elongate, often cohoiing together, but witliout cither caudicle or gland.
Spccies about 70, Asiatic and American, with a few AVest Indian.
The Indian spccies, with tiie exception of P. Jlookeriana and of a new spccies
recently discovered in Bm-ma, belong to the section Ncrvilia, in which the leaf and
flowers arc not contemporaneou-!. The species with contemporaneous leaf and flowers
are mostly natives of America, on!}- one being Japanese, and two Indian.

Stem 2 in. long, glabrous, with one or two sheathing bracts near the base. Leaf
2 in. broad, appearing with the flowers, reniform-orbicular, the margins lindulate, the
nerves sub-scaberulous near the base; petiole nearly as long as the stem, sub-scabemlousstriate.
Fbwers two, about 1 in. long; the floral bract linear-lancoolate, Iialf as long as
the pedicellate ovary. Sepals and petals sub-equal, linear-lanceolate. Lip oblong, with
two short blunt sub-triangular side lobes about its middle, aud an ovate-oblong sub-acute

end of the side lobes.
Sikkim, at an elevation of 3,000 feet; in flower in August; G. King, No. 2153.
Collected only once, and the exact locality iinknown. The leaf and flower are
contemporaneous, and in this respect the species is unique amongst the Sikkim species of
the genus. The foregoing description is drawn up from a diied sp9cimen. But, in
accordance with the arrangement of figuring only spccies of which fresh specimens
were available, no di'awing of this has been printed.
