The common ambrebule is found on the south and west of the continent of Marcrusia.

Etymology

From Arabic عنبر (ʕanbar, “amber”) + Latin bulla (“bubble, knob”).

Morphology

The ambrebule grows no taller than 4 meters, with a flattened, wide canopy. Its bark is dark and chocolate-colored, rough, hard, and deeply textured. The leaves are small, tough, and densely packed. In spring, the tree is dotted with tiny white flowers that bloom singly along its branches. Each flower produces a small, dry seed pod containing a single seed.

Physiology

Produces a secretion that hardens into bules (hardened resin spheres).

Behavior

Life Cycle

The ambrebule flowers in late spring, with blossoms emerging in April and persisting through May. After flowering, the tree begins secreting the bules along its bark and harden over the course of three to four weeks. The tree lives from 40 to 50 years.

Social Structure

Solitary nature; most ambrebules grow far apart unless cultivated.

Ecology

Natural propagation is difficult due to the low germination rate.
