| We compared the phyllotaxy and characteristics of the vascular system for two of the dioecious species. |
| From this and related work it has become necessary to define a meristem by its phyllotaxy and other growth patterns and not the identity of organs it produces. |
| In the field, a clockwise phyllotaxy of the foliage may be apparent when the plants are viewed from directly above. |
| Poaceae species present a conserved distichous phyllotaxy and share common properties with respect to leaf initiation. |
| For example, many pioneer trees exhibit orthotropic shoots that successively produce leaves in spiral or decussate phyllotaxy. |
| The fasciated stem extended in one plane, and the phyllotaxy of floral primordia was irregular. |
