umbel |
|
nominative |
inflorescence |
Pedunculate, determinate or indeterminate, simple or compound and apparently polychotomous, with one or more pedicellate flowers terminating each ultimate axis, the pedicels of each such floral set and the branches (rays) arising from each axial subdivision diverging from each other like the ribs of an umbrella, the whole plane, convex or concave distally. |
