Melhania polyneura is a plant in the family Malvaceae.
Melhania polyneura grows as a herb up to 20cm (10inches) tall. The oblong or ovate leaves are tomentose and measure up to 4cm (02inches) long. Inflorescences are four-flowered. The flowers have yellow petals.
The type specimen of Melhania polyneura, no longer extant, was collected in 1895 in Mwanza District, Tanzania. Its habitat may have been in wooded grasslands at altitudes of about 1200m (3,900feet). Changes in area land use to small farms since the initial specimen have resulted in the IUCN assessment as Critically Endangered.
