Belonging to the Gesneriaceae family, one of Paraboea capitata varieties is known as Paraboea capitata var. oblongifolia. This variety is endemic and can only be found in Peninsular Malaysia where it has been recorded to grow on four limestone hills in Perak and Kelantan. This variety is a stemless herb with a stout rootstock that is restricted to limestone where it grows near the base of limestone hills, on damp shaded rocks faces, and in gullies.

This variety is a perennial herb, sometimes with a rhizome up to 10 cm long. The typical or distinctive feature of the genus Paraboea is the type of indumentum. Normally the leaves are whitish underneath from a felty or woolly covering of hairs but some species are brown underneath. Its leaves are opposite and congested into a rosette. As its name suggests, it has oblong to obovate leaves and these distinguish it from the typical variety that has broadly ovate leaves. It has axillary inflorescences with the peduncle much longer than the leaves and usually covered with rusty brown hairs. The flower arrangement is cymose. The petals are white, glabrous and the corolla tube is short. The stamens are bright yellow, and the anthers transversely ellipsoid. The stigma is larger than the style that has a green base. Typical of this species is the linear and untwisted fruit that is glabrous, green when young, and opens by upper suture. The seeds are ovoid and brown.

Under the Malaysia Red List Category, this species variety is Endangered due to its risk of extinction caused by its habitat vulnerable to disturbances such as quarrying for cement or marble, urban development, ecotourism and agricultural activities.
