| Trunk or main stem | Branche | Twigs |
| Phyllotaxy | Alternate spiral to distichous (axial and bilateral symmetry) | Alternate spiral to distichous with twisting of the leaf axis giving a spiral leaf appearance (axial and bilateral symmetry) | Alternate spiral to distichous with torsion of the module giving a spiral leaf appearance (axial and bilateral symmetry) |
| Leaves type NB: In the wild, nodosities (swellings) are common on the petiole and rachis of leaves | Paripinnate compounds with one stipule per leaf sheath and another stipule at the end of the primary rachis. The leaves are composed of 2 to 16 pairs of leaflets on the compound leaf and 11 to 52 pairs of secondary leaflets on each leaflet. | Paripinnate compounds with one stipule per leaf sheath and another stipule at the end of the primary rachis.

| Preferential growth direction | Vertical in the proximal part and oblique to horizontal in its distal part | Oblique (minority) and horizontal (majority) | Horizontal |
| Ramification | Mesotone (majority) and Acrotone (minority) on growth modules | Mesotone (majority) and Acrotone (minority) on growth modules | No |
| Size of growth units (GUs) | Variable: 4.5 to 35.5 leaf scars; Long and short in places (3.85 to 51.4 cm) | Variability: 4 to 27 leaf scars; Long and short in places (4.5 to 43.6 cm) | Variability: 3 to 16 leaves; Short and very short in places (2.1 to 11 cm) |

| Leaf caducity | Dry season flowering period (January, February and March) | Dry season flowering period (January, February and March) | Dry season flowering period (January, February and March) |

| Axis complexity | Bears branching orders 2, 3 and short, greedy twigs | Bears only branching orders 3 and short gourmand branches | No (unbranched), but bears flowering clusters and shoots |
