What does it mean to be farinaceous? (From Tolstoy's Anna Karenina)

Having a mealy texture; rich in starch.

On the day of the races at Krasnoe Selo, Vronsky had come earlier than usual to eat beefsteak in the common messroom of the regiment.  He had no need to be strict with himself, as he had very quickly been brought down to the required light weight; but still he had to avoid gaining flesh, and so he eschewed farinaceous and sweet dishes.

From Leo Tolstoy's Anna Karenina.
