Differences in reproductive performance traits of two Platanthera species

Nordic Journal of Botany, EarlyView.
The species Platanthera bifolia and P. chlorantha (Orchidaceae) are both declining in Europe, but P. bifolia has been diminishing relatively more. Loss of habitats and landscape heterogeneity due to agricultural intensification or abandonment of less fertile areas are primary drivers of decreasing orchid populations.

Edaphic effects on forest structure and tree species composition in three seasonally dry tropical forest types in Cambodia

Nordic Journal of Botany, EarlyView.
Soil conditions are critical factors shaping forest structure and tree species composition in seasonally dry tropical forests (SDTFs); however, few studies have evaluated edaphic effects in Cambodia's unique lowland forest landscape, where different forest types coexist under similar climatic conditions.

Rediscovery of Passiflora clypeophylla (subgenus Decaloba): a highly threatened and narrow endemic species found within a karstic canyon in Guatemala

Nordic Journal of Botany, EarlyView.
Passiflora clypeophylla, an endemic species to the Guatemalan karstic forests last seen in 1889 and deemed extinct, was rediscovered in the Department of Alta Verapaz, east of Cobán. The species was known only from a single specimen hailed from the type locality, Rubel Cruz, where it has been found again. An additional location has been identified in a

Sedum zhenghaianum (Crassulaceae), a new species from Zhejiang and Jiangxi, East China

Nordic Journal of Botany, EarlyView.
In this paper, Sedum zhenghaianum sp. nov. is described as a new species based on morphological and molecular analyses, and its taxonomic relationships are discussed. Morphological analysis indicates that S. zhenghaianum should be classified in the genus Sedum sect. Sedum and is distinct from the related species S. tosaense in morphology, e.g.
