The overall shape of the flower when fully opened.
Star-shaped: the perianth segments spread widely in several directions and the flowers are more or less star like (stellate). |
Bell-shaped: a short tubular flower shaped like a bell (campanulate). |
||
Tubular: a flower that is more or less cylindrical. This condition can arise from the sepals and petals overlapping or being fused along their margins. |
Hooded: the upper perianth parts, usually the dorsal sepal and petals, are expanded and overlap or are fused along their margins to form a single structure (galea). This structure usually curves forwards to fully or partly enclose the column or other parts of the flower. |
||
Spider-shaped: the flower has long, slender, spider-like sepals and petals. |
Cupped: the sepals and petals remain incurved and do not spread widely. The flowers have a cupped appearance. |
||
Other: flowers that do not obviously fit into any of the other categories. |
