South Indian Olibanum is a narrowly endemic and
endangered deciduous tree. The leaves are compound and crowded at the
ends of branches. The flowers are borne in branched panicles at the
ends of the branches. Each branch produces 8-10 inflorescences and each
inflorescence produces about 30 flowers over a period of 5-14 days.
The flowers are stalked, greenish-white, 6 mm long, 5 mm across, mildly
fragrant, cup-shaped, bisexual. Petals are 5, white, free,
overlapping, 5 mm long and erect. Sepals are 5, minute, basally fused,
overlapping, light green, lightly velvet-hairy outside and persistent
without any further growth during post-fertilization stage in fruited
flowers. Stamens are inserted outside a fleshy annular pinkish-red
nectary disc which is present outside the ovary at the flower base.
They are 10 arranged in two whorls. The pistil is clearly distinguished
into ovary, style and stigma. The ovary is superior, trilocular, each
locule with two drooping ovules borne on axile placentation. The style
is light pink at base and dark green above, 4 mm long and trilobed. The
stigma is short, head-like, shiny. South Indian Olibanum is found only
in a small region of Eastern Ghats in Andhra Pradesh.
