in flower during April ; Pantling No. 472.
This interesting little plant has been met with only once, and the exact elevation
at whicli it gi-ew is uncerttiin. It is we believe a typical Sarcochihs as Brown appears
to have understood the genus. In the drawing, however, tha caudicl© of the pollinia
is shown as without a gland. It is probable, however, that, owing to the scautiuesi
of the material, the gland was overlooked in the dissection.

T l i c flowers of this magnificent species ai'e fleshy in texture; externally the sepals
and petals ai-e almost white, on the upper surface they are chocolate-brown, finely
banod with yellow. The lip is also white extci-nally, but on the upper surface the
hypochile is yellow, tho apical lobe has a broad marginal edging of the same colour,
and tho hypochile and its amides are marked with pink. The lower surface of the
lip has a projection opposite the point of union of the epichile and hypochile, and tho
substance of the Hp is hollowed into a funnel-shaped horizontal cavity, as is shown in
fig. 1 of the drawing.
