- Summary:
- The life history and reproductive biology of the Mauna Kea silversword was studied from 1985 to 1988 in the four known populations. Because flowers typically self-pollinate, low seed set suggests that the silversword is self-incompatible. Distance from the nearest flowering plant and seed set were significantly negatively correlated. Seed set was apparently limited by the number or activity of pollinating insects. Simulations using transition matrices indicated that adult survival contributed most to population growth when seedling production was low.
