Figure 1. Symptoms begin on lowest (oldest) leaves in canopy.
Figure 2. Progression of symptoms up through the canopy. Oldest
leaves are on the right, and youngest leaves are on the left.
Figure 3. All leaves in the canopy have died.
Figure 4. Diseased (left) vs. healthy (right) queen palms.
Figure 5. Brown stripe on petiole extends into the rachis of the
leaf.
Figure 6. Brown external petiole stripe corresponds with internal
discoloration of the petiole.
Figure 7. Leaflets on one side of the leaf have died (right), but
leaflets on opposite side are still living (left).
Figure 8. Progression of symptoms up through the canopy. Oldest
leaves are necrotic, and subsequently younger leaves are various
shades of yellow and green.
Figure 9. Note brown stripe on petiole of these leaves.
