Strongylodon macrobotrys, commonly known as the Jade Vine, is a climbing plant native to the rainforests of the Philippines. The Tagalog name for the climbing plant is tayabak.
The Jade Vine species grows along humid riverbanks on the island of Luzon. It climbs high into mature trees to reach direct sunlight. Thick woody stems support the weight of the plant as it spreads across the canopy.
Bright blue-green flowers form the main characteristic of the Jade Vine. The claw-shaped blossoms hang down in long cascading chains from upper tree branches.
The Secret Behind the Rare Turquoise Color
Turquoise is an exceptionally rare natural color among flowering plants. The Jade Vine creates its blue-green shade through a combination of plant pigments and light interaction.
Two primary pigments exist inside the flower cells. Malvin pigment provides a natural purple tone. Saponarin pigment adds a distinct yellow pigment. The compounds mix together inside the outer petal tissues.
Sunlight passes through the outer cells and hits the pigment mixture. The internal cell structure reflects the light back toward the surface. The reflection blends the purple and yellow pigments into a bright turquoise shade.
Strong sunlight can make the pale blossoms difficult to see high in the canopy. The plant is easily noticed by its flowers that have fallen onto the ground.
Fallen blooms change color as they dry out on the forest floor. The petals shift gradually from mint green to blue-green and finally to purple.
How Fruit Bats Pollinate the Flower
The shape of each Jade Vine flower resembles a sharp, curved claw. Individual blossoms measure up to seven centimeters in length along the outer curve. Such rigid structure protects the inner reproductive organs from rain and small insects.
A deep chamber at the base of the blossom secretes thick nectar. The necktar accumulates in small quantities. It attracts larger animals rather than ants or flies.
Fruit bats commonly act as the primary pollinators for the vine. The flying mammals search for food at night. They use sight and smell to locate flower clusters hanging below the tree canopy.
A bat lands upside down on the hanging flower stalk to drink nectar. The physical weight of the bat depresses the lower petal. Such action opens the rigid blossom.
Opening the petal releases an internal spring structure. The reproductive organs push outward. They press directly against the head and neck of the visiting bat.
Pollen sticks to the fur on the bat's head while the animal feeds. The transferred pollen fertilizes the next blossom when the same bat visits another flower cluster.
Seed Pods of the Jade Vine
Successful pollination triggers the formation of large, fleshy seed pods. The short, oblong pods grow directly along the hanging stalks.
Individual pods grow up to fifteen centimeters in length. The fruit reaches a size similar to a small melon. A thick green outer shell encases the fruit and protects the developing interior.
Up to twelve large seeds develop in a single row inside the fleshy chamber. These seeds have a smooth, dark brown coat. Each seed presses closely against the next one along the inner wall.
Fruit production depends entirely on the transfer of pollen between blossoms. The flowers require manual hand pollination in environments without natural bat presence
