It was reported Acer tutcheri Duthie, a new record of Acer L. in Zhejiang province. Relationship between A. buergerianum Miq. and var. jiujiangense Z. X. Yu, between A. buergerianum var. yentangense Fang et Fang f. and var. horizontale F. P. Metcalf was discussed, and A. buergerianum var....

Acer iranicum (Sapindaceae s. l., Aceroideae), from the upper limits of the lowland forests toward the midlands in the western part of the Hyrcanian forests, is described as new. Diagnostic characters for A. iranicum are sub-leathery to papery leaves, rounded, elongate sepals, oblong-ovate petals,...

Stem respiration (R_S) plays a crucial role in plant carbon budgets. However, its poor understanding limits our ability to model woody tissue and whole-tree respiration. A biophysical model of stem water and carbon fluxes (TReSpire) was calibrated on cedar, maple and oak trees during spring and late ...

Acer (Sapindaceae) is an exceptional study system for understanding the evolutionary history, divergence, and assembly of broad-leaved deciduous forests at higher latitudes. Maples stand out due to their high diversity, disjunct distribution pattern across the northern continents, and rich fossil...

Rhus asymmetrica sp. nov. from the lower Oligocene of Cervera (Catalonia, Spain) is characterized by a trifoliate leaf with a symmetric sessile apical leaflet and asymmetric lateral leaflets. The apical leaflet displays a serrate margin and decurrent base with pinnate primary venation,...

The floral characters of Acer yui are supplemented based on living plants flowering in April from the type locality. It is distinguishable based on both vegetative and floral characters between the two morphologically similar species, A. buergerianum and A. yui. Contrary to general consideration...

This is a commentary on a new research by Salomón et al. in the issue of New Phytologist (pp. 2214-2230), which discusses a process-based model of stem respiration that couples water and carbon fluxes at the organ level (TReSpire). The sap flow, stem diameter variations, xylem and soil water...

The frequency and severity of drought are expected to increase due to climate change; therefore, selection of tree species for afforestation should consider drought resistance of the species for maximum survival and conservation of natural habitats. In this study, three soil moisture regimes:...

Acer Linn. is a genus of highly variable species of the family Aceraceae. Currently, it is intricate to conduct species identification and phylogeny investigations using traditional morphological method. This study was applied to assess the applicability of Internal Transcribed Spacer 2 (ITS2) for...

Dipteronia (Sapindaceae) is an ancient relict woody genus, and contains just two extant species endemic to Southwestern and Central China. As sharing numerous morphological characters, Dipteronia and Acer have long been considered as sister groups forming the traditional family Aceraceae. However,...
