Pāṇini knows that there were two stars in this constellation; the two stars of Punarvasu and one of Tishya make three, but they are expressed by the dual number, as Tishya-Punarvasū (I.².63). But in *sūtra*, IV.3.64 he mentions Punarvasu in the singular, the form found both in the *Maitrāyaṇī* and *Kāṭhaka Saṁhitās* (*Vedic Index*, I.413). According to rule I.2.61 the singular form was optionally used in the Vedas.
