In this habitat, water slowly drain out from the moist hilly soil, stagnate and flow slowly in shallow manner and shade is more than 50 per cent. <em>P. alboflavescens </em>habitat was undisturbed, cool, moist, diversified with flora and fauna. The annual average temperature of the habitat was 25.92^oC and received 838mm rain during 2017-18. There were only 58 <em>P. alboflavescens </em>plants in the habitat. The older <em>P. alboflavescens </em>climb over the trunk, canopy of tall forest trees and flowers, green pods were observed in April 2018. The stems were gray, leaves were ovate (5-13x4-8.0cm), 5-7 lateral veins and petiole length was 2.0-3.0 cm. The smaller <em>P. alboflavescens </em>plants can be easily uprooted and replanted successfully. The height of <em>P. alboflavescens </em>was relatively 0.5ft to more than 20.0 m. <em>Idea malabarica </em>butterfly feed on nectar, leaves of <em>P. alboflavescens</em> and the activity was throughout the year. Adult butterflies glide slowly over canopy of forest trees and the activity was limited only within the above described habitat. The medicinal plant <em>P. alboflavescens </em>is at risk and <em>I. malabarica</em> is also at lower risk or near threatened as per the publication of IUCN.
