About
Pterospermum acerifolium, the bayur tree or karnikara tree, is a flowering plant indigenous to Southeast Asia, from India to Burma. It is most likely to grow naturally along forested stream banks. The best growing conditions are a seasonally moist then dry climate with access to full sunlight. Pterospermum acerifolium is an angiosperm that is traditionally included in the family Sterculiaceae; however, it is grouped in the expanded family Malvaceae as well. The classification Pterospermum is based on two Greek words, Pteron and Sperma, meaning "winged seed" and the species name acerifolium indicates leaves shaped like a maple's. There is an array of common names for Pterospermum acerifolium, depending on the region where it is grown. It is commonly referred to as Kanak Champa, Muchakunda or Karnikar Tree within its native range. In the Philippines, it is known as Bayog.
Uses
As mentioned before, one of the common names for Pterospermum acerifolium is the dinner plate tree. The utilization of the leaves is exactly what the name depicts. Mature leaves are very large, reaching a length and width of up to thirty five centimeters. They can be used as actual dinner plates or as packaging and storage by wrapping materials inside. In India they are shaped into regular dinner plates and soup bowls on moulds, some even stitched together with twigs. In Burma they are also used to dry tobacco upon. The leaves can also serve as a primitive method of re-enforcing roofs and preventing leaks. The pubescent under surface of the leaves is said to stop bleeding and can be used as tinder for a means of sparking fires. The flowers of the bayur tree can serve as a pleasant perfume and can even keep away insects. The flowers also provide a number of medicinal uses. An effective tonic can be prepared, as well as being used as a cure for inflammation, ulcers, blood problems, and even tumors. The reddish wood of the bayur tree can be used for planking.
