Taxon info
Clerodendrum is a genus of flowering plants in the Lamiaceae family. It is a member of the subfamily Ajugoideae, one of four subfamilies transferred from Verbenaceae to Lamiaceae based on morphological and molecular phylogenetics.

Biniuang is a small, smooth shrub growing to a height of 1 to 2 meters. Branches are green, streaked with purple, and four-angled. Lower leaves grow on long stalks and are heart-shaped, very large, measuring up to 32 centimeters wide; with pointed tips and obscurely toothed margins. Upper leaves become gradually smaller and finally pass into bracts. Panicles are large, pyramidal in form, lax, terminal, and 50 to 90 centimeters long. Flowers are crimson. Calyx is large, inflated, conical, and almost winged at the angles, the five lobes being elliptic or ovate and about 10 millimeters long. Corolla-tube, which is slightly longer than the calyx, divides into five, oblique, spreading, oblong lobes. Stamens are purple, very long - 5 to 6 centimeters in length. Fruit is about 1 centimeter in diameter, usually 2-lobed,and clasped by persistent calyx lobes.
