Description

Its rough branches are dark gray. It has oblong, hairless, leathery leaves are 16.2 - 21.6 by 6.75 - 8.1 centimeters. The leaves are covered in minute translucent impressions. The undersides of the leaves are paler than the upper surfaces. Its petioles are 1.3 centimeters long. Its bent peduncles are the same length as its petioles and are scaly at their base. Its 1.8 centimeter long, rounded sepals are united at their base, covered in minute, fine hairs. Its flowers have 6 petals in two rows of 3. Its smooth, linear-oblong outer petals are thick and leathery and tapered at their base. The upper 1.3 centimeters of its inner petals are joined at their margins. Its stamen are linear-oblong with a fleshy tip that extends above the anthers. Its gynoecium have ovaries that are covered in short rigid hairs and styles that have fluted ends.[3]

Reproductive Biology

Pollen is shed as permanent tetrads.[4]

Uses

Bioactive molecules isolated from its roots have been reported to have cytotoxic activity in tests with cultured human cancer cells.[5][6][7]
