from Easton's 1897 Bible Dictionary

Bolled
(Ex. 9:31), meaning "swollen or podded for seed," was adopted in
the Authorized Version from the version of Coverdale (1535). The
Revised Version has in the margin "was in bloom," which is the
more probable rendering of the Hebrew word. It is the fact that
in Egypt when barley is in ear (about February) flax is
blossoming.
