3.256.p2

ity atra indukalādīn mano-mada-hetutayā prasiddhān uktvā tat-samāna-mādhuryāyām api mālatyāṃ viśeṣa-kathanād idaṃ viśeṣaṇam |

Here, after mentioning the crescent moon and others that are celebrated as causes of delighting the mind, a special distinction is stated in Mālatī even though she possesses equal sweetness; hence this is viśeṣaṇa.
