The broadly ovate leaves of ton phluang, a deciduous tree with the botanical name Dipterocarpus tuberculatus (fig.), have a blunt tip and a rounded or heart-shaped base, and are somewhat reminiscent to those of the teak tree (fig.). The large leaves are widely used as a wrapper for foodstuffs as well as to thatch roofs of bamboo huts and dwellings, especially in the area of Mae Hong Son, where it grows abundantly.
