Figure 10 From: Have giant lobelias evolved several times independently?

Lobelioid seeds are extremely small and could presumably be carried over large distances by strong wind currents. The figure shows seeds from the Hawaiian endemic Clermontia kakeana around the eye of a needle; one gram contains about 36,000 seeds.Back to article page
