The mericarp of Heracleum mantegazzianum can be distinguished from other similar fruits in the genus by its conspicuously expanded vittae. |
|
The triglyceride and essential oil are located in separate, well-defined compartments, the seed endosperm and vittae, respectively. |
|
In L. juncta, each pale yellow elytron has five black vittae, with vitta 1 bordering sutural margin and extending from just below the base to the apex. |
