In the Viṣṇu purāṇa, Māṛṣā is described as the offspring of trees.
WHILST the Pracetasas were thus absorbed in their devotions, the trees spread and overshadowed the unprotected earth, and the people perished: the winds could not blow; the sky was shut out by the forests, and mankind was unable to labour for ten thousand years. When the sages, coming forth from the deep, beheld this, they were angry, and, being incensed, wind and flame issued from their mouths. The strong wind tore up the trees by their roots, and left them sear and dry, and the fierce fire consumed them, and the forests were cleared away. When Soma (the moon), the sovereign of the vegetable world, beheld all except a few of the trees destroyed, he went to the patriarchs, the Pracetasas, and said, “Restrain your indignation, princes, and listen to me. I will form an alliance between you and the trees. Prescient of futurity, I have nourished with my rays this precious maiden, the daughter of the woods. She is called Māṛṣā, and is assuredly the offspring of the trees. She shall be your bride, and the multiplier of the race of Dhruva. From a portion of your lustre and a portion of mine, oh mighty sages, the patriarch Dakṣa shall be born of her, who, endowed with a part of me, and composed of your vigour, shall be as resplendent as fire, and shall multiply the human race.
However, in the Mahābhārata, Yudhiṣṭhira describes her as the daughter of a tree.
"Yudhishthira then spoke, saying, 'My tongue never uttereth an untruth and my heart never inclineth to what is sinful. When my heart approveth of it, it can never be sinful. I have heard in the Purana that a lady of name Jatila, the foremost of all virtuous women belonging to the race of Gotama had married seven Rishis. So also an ascetic's daughter, born of a tree, had in former times united herself in marriage with ten brothers all bearing the same name of Prachetas and who were all of souls exalted by asceticism. O foremost of all that are acquainted with the rules of morality, it is said that obedience to superior is ever meritorious. Amongst all superiors, it is well-known that the mother is the foremost. Even she hath commanded us to enjoy Draupadi as we do anything obtained as alms. It is for this, O best of Brahmanas, that I regard the (proposed) act as virtuous.'
Was Yudhiṣṭhira mistaken or is there some other way to reconcile this?
