The position on the plant where the inflorescence arises. The inflorescences are produced from specialised floral nodes, the position of these nodes on a species varies and is of evolutionary significance.
 |
Terminal on a stem, tuber or pseudobulb: the inflorescence arises from the terminal nodes. |
 |
From an axil on a stem, pseudobulb or rhizome: the inflorescence arises from the axil of a leaf or bract. |
 |
Breaking through leaf: the inflorescence breaks through a basal part of the leaf. |
 |
From centre of leafy rosette: the inflorescence arises from the centre of a rosette of leaves. |
 |
From leaf base: the inflorescence arises from the base of a leaf. |
 |
Leaf opposed: in some epiphytes the inflorescence arises on a section of the stem opposite a leaf (not in the leaf axil). |
 |
Base of pseudobulb: the inflorescence is produced from nodes at the base of a pseudobulb or stem. |
