lANTHA PALLIDIFLORA. 
Pale-fiowei^ed lantha. 
GYNANDRIA MONANDRIA Nat. Ord. ORCHIDEM. 
Gen. Char — Petala minuta, conniventia, subaequalia, libera, inferne una 
cum labello magno dilatato inarticulato, breviter obtuse calcarato. An- 
thera operculifonnis, libera. Masses pollinis duo, dorso lobulato pedicello 
glanduloso affixae. 
lantha pallidi/hra. 
Stem none. Leaves binate, linear-lanceolate, four or five inches long, gla- 
brous and nerveless. Scape arising from between these leaves, in the 
present individual about half a foot high, and simple ; but evidently, as 
may be seen from the vestiges of the old scapes which had blossomed in 
their native country, sometimes attaining a much greater height, and 
branched ; cylindrical, glabrous, jointed, with scales at the joints, having 
small bracteas at the base of each flower. 
Flowers lax and distantly placed. Petals very small, connivent and stand- 
ing forward, so as to conceal the column of fructification, the three outer- 
most smallest and equal in size, the two innermost larger and broader, 
all of them white with purple stripes ; united together with the label- 
lum at the base, so as to form a short, obtusely 2-lobed spur. Lip very 
large, pendent, nearly plane, 2-lobed, at the base furnished with two 
yellow tubercles, the rest of it white, with faint purplish streaks, its mar- 
gin waved. Germen slender, pedicelliform, twisted. Column very short. 
Stigma concave, green. Anther hemispherical, yellowish, with two 
purplish spots, operculiform, free. Pollen-masses two, yellow, coriaceous, 
each with a small lobe behind, and fixed to a linear, oblong, white foot- 
stalk, which has at its base an oblong gland ; this gland projects beyond 
the operculum, where that is fixed upon the column. 
The subject of the accompanying plate seems to be too in- 
teresting for me to neglect this opportunity of figuring it, al- 
though, as far as can be conjectured from some old scapes which 
remain on the plant, another season might have afforded much 
finer flowering stems. The individual from which the drawing
