Orchids in the genus Rhomboda are usually terrestrial, perennial, deciduous, sympodial herbs with a creeping, fleshy, above-ground rhizome anchored to the ground by wiry roots. A few species are epiphytic. The leaves are spirally arranged around the stem with the upper leaves forming a loose rosette. They are dark green to maroon or brownish with a central white or red line. The flowers are resupinate or partly resupinate with the dorsal sepal and petals fused to form a hood over the column. The lateral sepals are similar to the dorsal sepal, free and often spreading. The labellum has a deep pouch near its base, a narrow middle section and often has a hooked tip.[3][4][2][5][6]
