Flowering and fruiting: November-March
The 2-merous form that is occasionally found in China resulted in the 2-merous Eriocaulon willdenovianum Moldenke ( E. longifolium Nees ex Kunth (1841), not Rafinesque (1840)) being put in synonymy under E. sexangulare in FRPS. These two species are distinct outside of China, and it is possible that the 2-merous plants in China represent a reduction from 3-merous to 2-merous within E. sexangulare. This question needs further study.
