Allium littoricola Z.H. Chen, Y.L. Xu & P. Li,in Zhang, Xie, Zhou, X.-P. Li, Yang, Xu, Wang, Chen et P. Li, 2026. 滨海葱 || taiwania.ntu.edu.tw/abstract/2138 AbstractA new species of Allium L. (Amaryllidaceae) from Zhejiang, eastern China, namely A. littoricola, was described and illustrated. Morphological analysis indicates this new species is similar to A. longistylum Baker, but differs in having ovoid bulb, tunic white, light-purple, membranous, leaf blades ascending, scape lateral, hollow in cross section or solid at base, perianth segments 5–6 × 2–3 mm, inner filaments base 1-toothed at each side; low altitude and coastal hillside habitat. Molecular phylogenetic analyses also support it as a new species and suggest that it is closely related to A. longistylum Baker.Keyword: Allium chinense, Allium longistylum, Allium sacculiferum, Allium thunbergii, phylogenyMorphology of Allium littoricola.A.

Tiny bits of Earth’s atmosphere have been drifting to the moon for billions of years, guided by Earth’s magnetic field. Rather than blocking particles, the magnetic field can funnel them along invisible lines that sometimes stretch all the way to the moon. This explains mysterious gases found in Apollo samples and suggests lunar soil may hold a long-term archive of Earth’s history. It could also become a valuable resource for future lunar explorers.

Comins Coch, Ceredigion: The winds have died down, so I head out on an eerily still morning among frozen fallen leaves and emerging catkinsThe bitter wind from the east rattles around the house, upturning plant pots and causing a number of worryingly loud crashes in the gathering dusk. The gale peaks around dawn, then blows itself out to leave an uncannily still, clear morning.In the lane, a deeply eroded trackway of indeterminate age, a fresh rash of fallen branches marks the passage of the storm, while a pair of jays dispute hoarsely in the fragment of woodland beside the stream.
