Notes
Closely related to T. philippinensis and T. oblita, from which it differs by the patent hairs growing fulvous in the lower part of the stems, from the former, which grows in the same area of Luzon, especially by the nearly rosulate, larger leaves, the winged petioles with dense, patent hairs, the longer calyx with narrower lobes and the light brown ribs of the nutlets.
