Burmannia lutescens is an annual, leaf-green, unbranched to branched herbaceous plant that reaches a height of 4.5 to 18 centimeters. It is mycotrophic . There is no rhizome, the roots are thickened and short. Leaves are absent at the base and only occur sporadically on the stem, where they are scale-like, triangularly pointed and 1.6 to 5 millimeters long.
The inflorescence is a double wrap consisting of an occasional single flower, but mostly two to three, rarely five or six flowers . The short-stalked flowers are 6.7 to 11 millimeters long and white in color with yellow lobes. The flower tube is cylindrical and 3.5 to 5 millimeters long, the multifarious wings are half elliptical, half wedge-shaped, square or reduced to a rib and run from the middle of the base of the outer flower lobes to the upper part or the base of the ovary. The outer lobes are egg-shaped to triangular or elongated-round, thin or fleshy thick, erect or with rolled or slightly rolled edges and 1 to 1.8 millimeters long, the inner small, circular, thin or fleshy thickened and 0.3 to 0 , 4 millimeters long. The stamens are sessile and start in the pharynx, the connective has two short, lateral arms that carry the thecae and a short, hanging spur at the base, but arms and spur can also be missing. The stylus is thread-shaped, at its end there are three almost sessile scars .
The ovaries are approximately spherical or broadly rhombic and 2.5 to 3.8 millimeters long. The capsule opens irregularly along transverse slits. The seeds are numerous, yellow and thread-like.
