Sapria ram is a holoparasitic flowering plant endemic to Thailand. It is found in central and southern Thailand. H. Bänziger & B. Hansen (1997) consider specimens in Thailand formerly identified as Sapria poilanei (currently considered to be endemic to Cambodia) to be Sapria ram.

Rhizanthes infanticida is a species of parasitic flowering plants without leaves, stems, roots, or photosynthetic tissue. They grow on roots of the Tetrastigma vine. They are found in the tropical forests of southern Thailand, western Malaysia, and Sumatra. The brown flowers are from 14 to 22 cm across. The flowers smell like a mammalian carcass and attract flies, which pollinate the blooms while laying their eggs inside. The flies' larvae die due to the lack of nutrients, hence the species name "infanticida".

Rhizanthes deceptor is a species of parasitic flowering plant without leaves, stems, roots, or photosynthetic tissue. They grow on roots of the Tetrastigma vine. They are only found in the tropical forests of Sumatra at 500–700 m. The flowers are white, with red-brown tips, and are from 20 to 27 cm across.
