The tropical tree Oreopanax shows a number of characters usually considered as adaptations to a temperate climate combined with typically tropical features. This evergreen tree grows in flushes and forms “resting buds” between successive flushes. Because of the lack of marked seasons in the tree's habitat, the growth cycle shows almost no correlation with external factors. The terminal resting bud appears only after the rest period; new leaves within the bud are formed only during bud growth and bud break which last 10‐14 weeks vs. 2‐3 weeks for taxa in the temperate zone. Abscisic acid seems not to be involved in the induction of the rest period.
