Abstract

Glandular hairs ofEremophila fraseri secrete a resin containing terpenoid and flavonoid components. Each glandular hair secretes about 0.2 μg resin, which constitutes 17% of the mature leaf dry weight. The glandular heads are characterized by proliferated endoplasmic reticulum associated with numerous amoeboid plastids having reduced internal lamellae. Nuclear crystals occur in the stalk and head cells of the glands. The head cells also contain calcium oxalate crystals. Resin release occurs through an apical secretion cavity. Cutinization of the walls of the head and supporting cells, and the role of specialized structures of the head cells in resin formation are discussed.
