Phenological response to climatic change depends on spring warming velocity
Communications Earth & EnvironmentClimatic change is dramatically altering phenology but generalities regarding tempo and mode of response remain limited. Here we present a general model framework incorporating spring temperature, velocity of spring warming, and species’ thermal ...

Nordic Journal of Botany, EarlyView.Phyllanthus asteranthos Croizat has been treated as a synonym of P. pulcher Wall. ex Müll. Arg. (syn. Nymphanthus glaucescens (Miq.) R.W.Bouman) since 1987. Through detailed morphological observations of living plants and critical examinations of type materials and additional specimens, this study revealed that the two taxa are morphologically very ...

Taxonomic identities of Coelogyne roseans, C. chen‐tsii and C. niana (Coelogyninae, Orchidaceae)
Nordic Journal of Botany, EarlyView.The taxonomic identities of Coelogyne roseans (= Pholidota roseans) and C. niana (= P. niana) have long been misunderstood. Our findings indicate that C. chen‐tsii (= P. longipes) is conspecific with C. niana, consequentially C. chen‐tsii is reduced to a synonym of C. niana. Although C. roseans and C.

Breynia phuongiana (Phyllanthaceae), a new species from the Central Highlands of Vietnam
Nordic Journal of Botany, EarlyView.A new species, Breynia phuongiana (Phyllanthaceae subgen. Sauropus), is described and illustrated from the Central Highlands of Vietnam. It is morphologically similar to B. beillei, B. bonii, and B. thorelii, but differs in having oblong‐elliptic leaves, sepals marked with reddish striations, an androphore exceeding 1 mm in length, and distinctly ...

Incorporating climate data with machine learning can improve rice phenology estimation
Environmental Research LettersCrop phenology provides essential information for crop management and production. Satellite-based methods are commonly used for phenology estimation but still struggle to capture interannual variations of phenological events.
