11c Leaves against-continuous, oblong, at the base pointed, above very sharply pointed, when dry leathery and lead-colored, glabrous on both sides of, clearly 3 nerved (near 5 nerved), 14 - 20 by 6 - 7½ cm. Petiole stalk 2 - 2½ cm long, glabrous, thick. Peduncle separately, axillär, 10 cm long. Blooms plus or minus 1 cm in diameter, in simple (+/-10 - 12 flowers) umbels. Pedicels glabrous, plus or minus 2½ cm long, Corolla flaps wide, flattened, rounded off, very short-shaggy. Corona scales above and below pointed, higher up stalked. Flat in the center. With 15 meters of highly winding stems, living in the presence of Hoya cinnamomifolia Hook., but immediately recognizable, because with this (new?) type of each leaf pair often a blade does not development.
