Epiphytal. _Stems_ erect, club shaped, somewhat flattened, light green, one to two feet high, retaining the leaves for two years, when mature becoming deeply furrowed and swollen below the nodes, the internodes partially sheathed by the withered bases of the leaves: it is these tumid internodes which give the appearance of a necklace, whence the name _moniliforme_ came to be applied, though erroneously, to the plant. _Leaves_ distichous, oblong obtuse, obliquely emarginate, pea-green. _Peduncles_ from the axils of the leaves of the two-year old stems, or from the joints whence the leaves have fallen, two to three flowered, with small acute appressed bracts. _Flowers_ bright coloured and pleasing, three inches across; _sepals_ oblong acute, venose, their base produced into a blunt striated spur, white below and of a bright rosy pink in the upper half; _petals_ ovate, of the same colour as the sepals; _lip_ ovate, cucullate, reflexed, obscurely three-lobed, attenuated at the base, and serrulate on the margin, with an elevated pubescent crest along the disk, white below, having two crimson spots about the centre, the apical portion wholly rich magenta-crimson. _Column_ short, the lip articulated at the end of its prolonged base.
