Botanical Description

D. fe­brifuga falls under the family of Saxifragaceae. It is an erect, evergreen shrub, 1-3 m tall, with terete twigs and variably pubescent. [4]

The leaves are arranged op­posite, simple, ovate, elliptical to oblong, measure 7.5-30 cm x 2.5-12.5 cm, wedge-shaped at base, short-to long-acuminate at apex, with serrate-dentate margin and variably pubescent. The petiole is 1.5-6 cm long while the stipules are absent. [4]

The inflorescence is a terminal, erect panicle, 4-15(-20) cm long and up to 25 cm in diametre, many-flow­ered while the axes are minutely pubescent. [4]

The flowers are bisexual, actinomorphic while the pedicel is 3-8 mm long. The sepal tube is bell-shaped, 2-4 mm long and with 5-6 teeth while there are 5-6(-7) petals which are valvate, 5-10 mm long, oblong, acute or obtuse and from light to dark blue. The stamens are diplo-(poly-) stemone. The ovary is semi-inferior, 1-locular, many-­ovuled and with 3-5 styles. [4]

The fruit is a berry, which is nearly spherical, about 5 mm in diametre, with persistent sepal and styles. [4]
