Palmyra sprout (also known as Palmyra Tuber) is a sprout that grows on Palmyra palms or Borassus flabellifer. The germinated seed's hard shell is also cut open to take out the crunchy kernel, which tastes like a sweeter water chestnut. It is called as “Theaga” (తేగ / తీగ) in Telugu and as "panam kilangu" (பனம் கிழங்கு) in Tamil. The white kernel of the ripe palm fruit after being left for a few months has got its uses. It can be dried or boiled to form Odiyal, a hard chewable snack.
In the states of Tamil Nadu, Bihar and Andhra Pradesh, India, and in Jaffna, Sri Lanka, the seeds are planted and made to germinate and the fleshy stems (below the surface) are boiled or roasted and eaten. It is very fibrous and nutritious, known as Panai Kizhangu or Panamkizhangu in Tamil and Thegalu or Gaygulu or Gengulu (especially in Andhra pradesh and Telangana areas) in Telugu.
