What the kulavṛkṣa means?

The oldest Sanskrit grammar writen by an european

I just learned about it from "The Sanskrit Grammar and Manuscripts of Father Heinrich Roth S.J. 1620-1668: Facsimile Edition of Biblioteca Nazionale Rome Mss or 171 and 172". This grammar was never printed, the first page of the manuscript can be seen bellow.

The above mentioned book also contains two manuscripts, one of Sadānada's Vedāntasāra and one of Veṇīdatta's Pañcatattvaprakāśa along with Father Roth's commentary.
