Seed & fruit parts of Pomaderris elliptica (0011198)

Опис:

Seed sample of Pomaderris elliptica (Yellow Dogwood). Mature seeds are typically very dark brown to black. Immature or infested seeds are typically pale brown. White appendage is an elaiosome. This collection shows a syndrome commonly observed in Pomaderrris apetala where the membraneous operculum fails or only partly develops in the coccarium segments and so fails to release the seed.
