Description Aeschynanthus intraflavus is an epiphytic subshrub. The stems are scrambling, trailing, and up to long. The branches are up to long, light green when young, and become brown with age.
The leaves are arranged oppositely, thick, leathery, long, and wide. The leaves are narrowly to broadly elliptical, and have smooth margins. The leaf stems are long. The plants have triangular bracts.
The inflorescences have one or two flowers. The flower stems are light green or orange, and long. The calyx has pale green lobes, which are orange towards the apex, narrowly linear, and long. The corolla is tube-shaped, reddish-orange on the outside, and pale yellow on the inside. The corolla is around long, around wide at the base, and around wide at the mouth. The flowers have four stamens.
The fruit is a linear-cylindric capsule, up to long, and up to wide. The fruits have numerous seeds, which are around long. The seeds have small protuberances, nine hairs at one end, and one hair at the other end.
Aeschynanthus intraflavus appears similar to Aeschynanthus arfakensis, although the latter has orange-yellow flowers, which are purpish towards the apex.
