Miniature fan-shaped epiphytes. Stems short to elongate-pendent. Leaves strongly bilaterally compressed, equitant, often spotted and suffused with purple. Inflorescences axillary, pedunculate, laxly pendent racemes, the rachis subumbellate or elongate, often becoming paniculate by the successive production of secondary branches. Flowers spidery. Sepals and petals free, spreading, subsimilar, subequal. Lip three-lobed, clawed, the lateral lobes auriculate, the midlobe clawed, often shaped like an anchor or arrowhead. Column elongate, straight, club-shaped, the anther dorsal; pollinia 2, on a common broadly spatulate stipe and minute circular viscidium.


From the Greek macros, meaning large, and klinion, meaning a little bed, in reference to the conspicuous clinandrium.
