Abstract Understanding the Cenozoic vegetation history of what is now Qinghai–Tibetan Plateau crucial for elucidating co‐evolutionary dynamics between plateau development, its environment, and organisms it hosts. In this study, we conduct a comprehensive analysis phytoliths within late Oligocene–Early Miocene lacustrine sedimentary section Lunpola Basin, central Plateau. The diverse phytolith morphotype assemblages indicate that Tibetan region mainly comprised mixed coniferous broad‐leaved forest. Grasses in understory primarily consisted Pooideae, distinguished by morphotypes such as rondel, crenate Stipa ‐type bilobate forms. Combined with previous work, infer riparian transitioned from humid subtropical forest, dominated woody plants during middle Eocene, to more seasonally arid open woodland containing abundant herbaceous before developing into cooler forest Miocene. growth retreat Tethys Ocean, together uplift Himalaya, contributed change.

Abstract Southwest China is characterized by high plateaus, large mountain systems, and deeply incised dry valleys formed major rivers their tributaries. Despite the considerable attention given to alpine plant radiations in this region, timing mode of diversification numerous valley lineages remain unknown. To address knowledge gap, we investigated macroevolution Isodon (Lamiaceae), a lineage commonly distributed southwest wetter areas Asia Africa. We reconstructed robust phylogeny encompassing nearly 90% approximately 140 extant species using transcriptome genome-resequencing data. Our results suggest rapid radiation during Pliocene that coincided with habit shift from herbs shrubs habitat humid valleys. The shrubby growth form likely acted as preadaptation allowing for movement into these Ecological analyses highlight drought-related factors key drivers influencing niche preferences different forms richness Isodon. interplay between topography development East Asian monsoon since middle Miocene contributed formation biome China. This study enhances our understanding evolutionary dynamics ecological shaping distinctive flora reveals strategies employed montane plants response climate change dryland expansion, thus facilitating conservation efforts globally.
