description

Burmannia candelabrum is an annual, almost always unbranched, seldom branched, succulent herbaceous plant that reaches a height of 5.5 to 25 centimeters at flowering time. It has been described as completely mycotrophic , but this status has not been established. There is no rhizome, the roots are fibrous and short. The leaves are 2.3 to 4.5 millimeters long, are absent at the base and only appear sporadically on the stem, where they are lanceolate, tapering and tightly fitting.

The inflorescence is an inflorescence consisting of between two and four or just one single flowers , which occasionally branches out in the shape of a candelabra with several flowers . The clearly and upright stalked, triple-winged flowers are 6 to 11.2 millimeters long and purple to bluish in color. The flower tube is cylindrical and 2.8 to 4.2 millimeters long, the 2.1 to 4.2 millimeter wide wings are wide, halved, obovate, blunt or rounded at the outer end and run from the base of the corolla lobes to below the base of the ovary . The outer lobes are triangular, obovate, thin to fleshy, upright with a sack-like furrow parallel to the edge, sometimes only in the lower half, and are around 1.1 to 1.4 millimeters long and 2 to 2.5 millimeters wide. The inner lobes are 0.4 to 0.6 millimeters long and erect, lanceolate, thin to fleshy, blunt at the outer end. The stamens are sessile and start in the pharynx, below the inner lobes. The connective is forked and has a blunt, thick, downward-pointing spur. The stylus is as long as the corolla tube together with the scars . The stylus is thickened, thread-like, at its end are the three sessile, trumpet-shaped scars.

The ovaries are approximately spherical to obovate and 3 to 4 millimeters long. The approximately spherical and 3 to 5.5 millimeters long capsule opens along irregular transverse slits. The seeds are numerous and elliptical in shape.

distribution
