Fruit production in Cyclopogon cranichoides is pollen limited (R. N. Calvo 1990). Natural fruit set was 26–62% over a 4-year period, whereas hand pollinations gave better than 96% fruit set. Contrary to most other studies of orchids, Calvo did not detect a cost of reproduction associated with resource constraints.
