description
Burmannia sphagnoides is a perennial, leaf-green, continuously whitish, unbranched to seldom branched herbaceous plant that reaches a stature height of around 2.8 to 4 centimeters at flowering time. The stem is thickened, thread-like and succulent . It is mycotrophic . The rhizome is cylindrical, upright and 1.1 to 1.5 (rarely 0.75 to 2.6) centimeters long and densely covered with two-line, ovate-lanceolate scale sheets. The roots are fibrous and short. The leaves are close at the base and lighter towards the outer end, the leaves at the base are 4.7 to 7.2 millimeters long and 3 to 4 millimeters wide, the leaves on the stem are similar, but narrower, they are 4.5 to 6 , 8 millimeters long and 2.5 to 3.2 millimeters wide. The bracts are ovate-lanceolate, tapering to a point and 5 to 8 millimeters long.
The heady inflorescence consists of three to eight flowers . The sessile flowers are 8.5 to 10.6 millimeters long and cleistogamous with a white thickened crown . The flower tube is cylindrical and around 4 millimeters long, there are no wings. The 2 to 2.4 millimeter long outer lobes are broadly triangular, upright and fleshy thickened with a pointed outer end. The inner ones are elongated-round to circular, blunt to rounded, fleshy, thickened and around 1 millimeter long. The stamens are sessile and start in the throat just below the inner lobes , the connective is bar-shaped and has two short, lateral arms that support the thecae , a spur is missing. The stylus is as long as the corolla tube and thickened thread-like, at its end are the three almost sessile, funnel-shaped scars .
The ovaries are approximately spherical and 5 millimeters long and 5 millimeters wide. The approximately spherical capsule is 5 to 5.5 millimeters long, the seeds are numerous and approximately spherical.
