Xie, S.-P., S.-H. Zhang, T.-Y. Chen, X.-C. Zhang, X. Zeng, and Y. Yu. 2018. Late Miocene occurrence of monogeneric family Oleandraceae from southwest China and its implications on evolution of eupolypods I. Review of Palaeobotany and Palynology 256: 13–19. https://doi.org/10.1016/j.revpalbo.2018.05.002

Yunnan in SW China is a world renowned hotspot for diverse species of vascular plants such as ferns. However, fossil records of the Cenozoic ferns there are insufficient to clarify their phylogeny and historical biogeography from a geological perspective. Among these derived ferns, the monogeneric f…

Petersen, K. B., and M. Burd. 2018. The adaptive value of heterospory: Evidence from Selaginella. Evolution 72: 1080–1091. https://doi.org/10.1111/evo.13484

Heterospory was a pivotal evolutionary innovation for land plants, but it has never been clear why it evolved. We used the geographic distributions of 114 species of the heterosporous lycophyte Selaginella to explore the functional ecology of microspore and megaspore size, traits that would be corre…
