It is a scandent shrub, and its purple-black drupes are likely dispersed by birds. |
Fruiting plants are immediately recognizable by the unique bright blue color of their drupes, but sterile shrubs are very nondescript and easily overlooked. |
In the raspberry and bramble several small drupes or drupels are aggregated so as to constitute an etaerio. |
The drupes are metallic blue that later turn blue-black to black and ripen in October. |
This appears to have given rise to both single-seeded drupes and multi-seeded pyrenes early in evolution, and to berries later in evolution. |
The multiple fruit consists of small drupes or achenes grouped together in a single unit, and is usually round or oval shaped. |
