See text Palissya is an extinct form genus of female (ovule-bearing) conifer cones, known from the Late Triassic (Rhaetian) to the Early Cretaceous (Aptian).

The cone of Palissya is noted for its unusual catkin-like construction: Slender bracts (modified leaves) are rigidly attached in a helical pattern around a tall woody core.

The adaxial (upper) surface of each bract bears two parallel rows of ovules which are encased in cup-like structures formed by scales.

Several Australasian species with fragile cones were referred to the separate genus Knezourocarpon,[2] though some were later moved back into Palissya.

[1][2] True specimens of Palissya first appeared in the Northern Hemisphere during the latest Triassic (Rhaetian) and spread to Eastern Gondwana (modern Australia, New Zealand, and Antarctica) during the Middle Jurassic.
