In the publication of this article [1], there was an error in the Abstract section which was published with incorrect pollen size results. The error: ‘Pollens of all taxa are monads, spheroidally shaped with 28-457 µm diameter, and 15-pantocolpate apertures type with microechinate ornamentation.’ Should instead read: ‘Pollens of all taxa are monads, spheroidally shaped with 28–47 µm diameter, and 15-pantocolpate apertures type with microechinate ornamentation.’ This has now been updated in the original article [1].Mahidol UniversityAgricultural and Biological SciencesErratumSCOPUS10.1186/s40529-016-0144-8
