Kāśa has other meanings too: see all meanings of Kāśa.

Dīrghatapas is a king of the Kāśī line of the lunar vaṃśa. The Brahma Purāṇa gives his line twice. In the first telling he is the son of Kāśa and the brother of Kāśipa, and his son is the learned Dhanva, father of Dhanvantari. In the second he is the son of Kāśika, also called Kāśeya, and the father of the learned Dhanvantari. From his line came Ketumān, Bhīmaratha and Divodāsa, the lord of Vārāṇasī.

In the line of Kshatravṛddha

The teller of the Purāṇa tells the munis the line of Āyu‘s son Kshatravṛddha, the kings of Kāśī. Kshatravṛddha’s son was Sunahotra, whose sons were Kāśa, Śala and Gṛtsamada. Śala’s son was Ārshṭisena, and Ārshṭisena’s son was a second Kāśa. This Kāśa had two sons, Kāśipa and Dīrghatapas. Dīrghatapas’s son was Dhanva, a learned king. Dhanva performed great tapas, and in his old age Dhanvantari was born to him: the Dhanvantari who had arisen before from a portion of the devas was now born from a human portion. He became the great king of Kāśī, learned Āyurveda from Bharadvāja, removed every disease, divided that śāstra into eight parts and taught it to his disciples.

Dhanvantari’s son was Ketumān, his son the learned Bhīmaratha, and his son Divodāsa, lord of Vārāṇasī.
