Rangoon Creeper
This plant is distributed from India to Malay Peninsula and Java Islands.   It grows on sunny mountain slopes and by water.   It initially looks like a low tree, then the lower part of the trunk is upright and the upper part is vine-like.   It has sharp thorns on the trunk at regular intervals to entwine with other trees in order to extend and becomes 5m in height.   The vine is strong and can be more than 8m in length.
The flower has an aroma like peach, and is initially white, soon become pink, and then crimson.   It is about 3cm in diameter and has a calyx tube which is thin, long and around 5cm in length.   Capturing the change of the colour, the genus name, Quisqualis, consists of the Latin words, quis meaning who and quails meaning what.
The ripened fruit is called 'Shikunshi' and has been used as a medication (an anthelmintics) for roundworm (Ascaris lumbricoides) and pinworm (Enterobius vermicularis).   Shikunshi contains quisqualic acid as an active ingredient which is an alkaloid and a derivative of 2,3-di amino propionic acid.   Quisqualic acid is isolated from the fruits of the plants belonging to the genus, Quisqualis, such as Q. chinensis or Q. indica and is named after the genus name, Quisqualis.
Most of leaves are opposite.  The leaf blade is thin, oval and 7 to 14cm in length.   The leaf stem is 1 to 2cm in length.   There is a joint at the base of the leaf stem, when the leaf falls some part of the stem remains to form a thorn-like projection.
