Observations made in Salta, northern Argentina, for a complete flowering season of five plants from several patches, allowed the authors to conclude: 1. anthesis lasts 9-13 hours and consists of two floral phases, in the last of which the stigma is not receptive; 2. stigma is receptive in the bud when anthers are not dehiscent, hence the flowers are protogynous; 3. nectar is secreted during phase 1 only; 4. the nectar composition fits that of melittophylous plants; 5. rain or drizzle do not affect the nectar composition or pollen viability because they are highly protected but do affect visitation by pollinators; 6. flowers are flag-blossom pollination units with pollen presented on stylar subapical trichomes, adapted to medium-sized hymeno...
