Hildegardia populifolia is a species of flowering plant in the family Malvaceae. It is found only in the Eastern Ghats of Andhra Pradesh and Tamil Nadu in India. It is threatened by habitat loss; just about 20 trees are known to exist on the eastern slopes of the Kalrayan Hills.
This is a deciduous tree growing up to 20 meters tall. It has lobed leaves and panicles of flowers with red sepals and no petals. Most trees produce both male and bisexual flowers.[1]
The bee Trigona iridipennis feeds on the pollen and nectar. The flowers are visited by several bird species, such as the red-vented bulbul (Pycnonotus cafer), rufous-backed shrike (Lanius schach), blue-tailed bee-eater (Merops philippinus), and stork-billed kingfisher (Pelargopsis capensis), some of which are predators of the bee.[1]
