Melhania angustifolia is a plant in the family Malvaceae. It is endemic to Zanzibar.
Melhania angustifolia grows as a suffrutex (subshrub) or shrub up to 2m (07feet) tall. The ovate to oblong leaves measure up to 8.3cm (03.3inches) long. Inflorescences are two or three-flowered, on a stalk measuring up to 4cm (02inches) long. The flowers have bright yellow petals.
Melhania angustifolia is native to the Zanzibar Archipelago where only seven specimens are known and the species is threatened by tourism-linked development. Its habitat is in bushland or on sand, near sea level.
