Page "Pusyamitra Sunga" Paragraph 9

It is written in the Harivamsa Purana for Pusyamitra Sunga that an Audbhijja Kaashyapa Dwija Senani will spread the tradition of Yajna again.

In this line of Harivamsa, the word Audbhijja ( ओद ् भ ि ज ् ज ) means plant-born.

Thus according to The Harivamsa Purana, A plant-born Kaashyapa Brahmin General will restore the Vedic tradition.

In Aryan Dynasties, there was a tradition to derive their dynastic names from the various objects of nature like the Sun ( Suryavanshi ), the Moon ( Chandravanshi ), Fire ( Agnivanshi ), Vegetation ( Pallava, Kadamba ) etc.

Accroding to Dr. Hemchandjra Raychaudhari, Sunga Dynasty took their surname from a tree.

He further gave the example of Indian dynasties like Kadamba ( a tree name ) of Banavasi, Pallava ( Sanskrit word for " branch and twig ") of Kanchi and Narikela-Kramukanvaya ( Narikela a Sanskrit word for the Coconut ) of Champa.

The meaning of " Sunga " is the fig tree in Sanskrit.

So according to him, Sungas took their dynastic name from the fig tree.
