Pterocarpus indicus is a species of Pterocarpus native to southeastern Asia, northern Australasia, and the western Pacific Ocean islands, in Cambodia, southernmost China, East Timor, Indonesia, Malaysia, Papua New Guinea, the Philippines, the Ryukyu Islands, the Solomon Islands, Thailand, and Vietnam. Pterocarpus indicus was one of two species (the other being Eysenhardtia polystachya) used as a source for the 16th- to 18th-century traditional diuretic known as lignum nephriticum. Many populations of Pterocarpus indicus are seriously threatened. [Wikipedia]
(2) Khlong Wat Pradu is a defunct canal once situated off the city island in the northeastern area of Ayutthaya in the Phai Ling Sub-district. The canal was named after the temple Wat Pradu, to which it connected. The mouth of the canal was at the Lam Khu Khue Na in between Wat Krajom and Wat Nang Chi. Based on Kaempfer’s maps, Khlong Wat Pradu linked up with a north-south canal that flowed west of Wat Kudi Dao and Wat Samannakot and connected with Khlong Kramang about 50 metres from its junction with Khlong Ban Bat and Khlong Dusit. The canal can be seen on a photo with references 4064 - BN 391 684 9 Jun 44//F/36 (043) in the Williams-Hunt Aerial Photos Collection. Khlong Wat Pradu ran parallel and north of a wooden bridge, starting at the Wat Pradu Boat landing and leading to the temple. Khlong Wat Pradu has been filled up today but ran earlier just north of the Wat Pradu Songtham premises.
(3) Khlong Wat Nang Chi is a defunct canal running more or less parallel to Khlong Wat Pradu. The mouth of the canal was at the Lam Khu Khue Na near Wat Nang Chi, and the waterway ran in an eastern direction where it joined a north-south running canal coming from Wat Pradu and running into Khlong Kramang.
