Parkia sumatrana subsp. streptocarpa
Content
Distribution
Asia-Tropical: Borneo; Malaya (Peninsular Malaysia present); Thailand (Thailand present), Burma present
Burma, Thailand, Indochina; in Malesia: Malay Peninsula, and perhaps Borneo. — .
Uses
Young leaves and young seeds are edible (Nielsen 1981; Nielsen & Santisuk 1985). The powdered bark is reported as having medicinal uses, including against leeches in Indochina (Vidal 5063).
Notes
1. Although the majority of Parkia specimens from Malesia with medium-sized oblong leaflets are readily referrable to either P. singulars subsp. borneensis or to P. sumatrana, a minority are not.
Using all available material, there is a continuum of variation in leaf characters (number of pairs of pinnae and leaflets, size and shape of leaflets) between the two taxa. The majority of 'intermediate ' or unplaced collections are from Borneo. Roster mans 10237 with narrow, glabrous, twisted pods an I Hallier 2420 with rather numerous leaflets, raise the possibility that P. sumatrana subsp. strep- toi arpa occurs in Borneo. The capitula of Haviland 2907 differ from both P. sumatrana and P. singularis by having a well developed staminodial fringe ancl a spherical ball of fertile flowers.
An interesting situation exists where P. singularis and P. sumatrana can be readily distinguished from each other where they are sympatric in the western part of Malesia, but there appears to be a gr dation in vegetative characters between them in Be Tieo
2. Little flowering material is available for P. sumatrana and it is not possible to say whether the difference in the corolla lobes between subsp. sumatrana and subsp. streptocarpa is constant.
