Most Palm are tree-like, with single trunks and either fan shaped (palmate) or feather shaped (pinnate
) compound leaves.
We determined five ontogenetic stages for both species of Euterpe and hybrids: (i) seedling: individual with up to three leaves with palmate leaflets; (ii) sapling: individual with pinnate
leaves, without exposed stem; (iii) juvenile: individual with pinnate
leaves and exposed stem; (iv) immature: individual with pinnate
leaves, exposed stem and with no signs of reproductive events; (v) adult: individual with pinnate
leaves, exposed stem, and signs of reproduction such as infrutescences or their scars on the stem.
The leaves at the base of the plant are simple, 0.5-2 in (1.3-5.1 cm) long and shallowly lobed, while leaves higher on the stems are feathery pinnate
, divided into numerous leaves.

Lamina stomatal frequency was determined on the abaxial and adaxial surfaces for two leaflets of the medium part of leaf + 2 of four plants randomly selected (pinnate
