air Dillenia suffruticosa Family Dilleniaceae updated Nov 10 Where seen? This large shrub to tree with large glossy green leaves, cheery yellow flowers and pink star-shaped 'fruits' is commonly seen. According to Corners, this is the most common Dillenia in Malaya. Corners says "one may regard it as a rank tropical weed, but the more we become acquainted with it, the greater is our admiration. It is a plant of enormous vigour and blooms every day of its life which may be fifty if not a hundred years. We should be thankful that there is such a fascinating plant ready to clothe the wasteland". It was formerly known as Wormia suffruticosa. Features: A large shrub to shrubby tree to 6m tall. Leaves large (15-35cm) oval and 'cabbagey' with a toothed edge and a fold near the stalk. Flower yellow, large (8-10cm) with five large thin petals, several flowers on a long stalk. The flowers open one at a time along the inflorescence, the bud swelling visibly and turning yellow on the morning before the day it would bloom. The next day around 3am, the flower starts to open becoming fully bloomed about an hour before sunrise.The petals drop off by 4pm and the sepals fold back on the young fruit in the evening. The flower stalk rotates slowly from pointing down when the flower blooms to pointing up when it starts to fruit. The flower has no scent and produces no nectar. The fruits take exactly five weeks to set and opens at 3am. The pink star-shaped fruit capsule is fully expanded long before sunrise, with 7-8 'rays' displaying purple seeds that have a fleshy bright red aril. The empty husk falls off at about 8am the following day. According to Corners, bees appear to be the pollinators that gather their pollen, as well as by small beetles and flies that scramble over the flowers. Small birds pick up the seeds from the opened star-shaped fruits, especially bulbuls. The seeds are swallowed whole together the fleshy aril around them, and thus dispersed by the birds. Role in the habitat: The large leaves are used by tailorbirds to sew together into a pouch for their tiny nests. Unfortunately, after they fall to the ground, the large leaves also hold shallow pools of rainwater in which mosquitos breed. Thus areas with Simpoh air are often mosquito infested. Human uses: The large leaves of the Simpoh air were used to wrap food such as tempeh (fermented soyabean cakes), or formed into shallow cones to contain traditional "fast food" such as rojak. |
