Bauhinia naniflora: a new species of section Amaria (Cercidoideae: Leguminosae) from Colombia

Nordic Journal of Botany, EarlyView.
Bauhinia, the most species‐rich genus of Cercidoideae (Leguminosae), is pantropically distributed and includes four sections in the Americas. During an ongoing taxonomic revision of American Cercidoideae, a new species of Bauhinia sect. Amaria ser. Decandrae currently endemic to Colombia was identified and is here described as Bauhinia naniflorasp nov.

Diversity of pollen morphology in species of Cercidoideae (Fabaceae) from Cerrado forest fragments, Brazil: Bauhinia L. and Schnella Raddi

The Cercidoideae subfamily has a wide geographic distribution in Brazil, with its most representative genera, Bauhinia L. and Schnella Raddi. This study aims to describe the pollen morphology of native species of Bauhinia and Schnella that occur in ...

Two new endemic species of Portulaca (Portulacaceae) from the Brazilian Pampa grasslands

Nordic Journal of Botany, EarlyView.
Portulaca L. is a monophyletic, cosmopolitan genus of succulent plants comprising ca 153 species, with particularly high diversity in xerophytic ecosystems in tropical and subtropical regions. Based on morphological evidence, we describe and illustrate two new species from the Brazilian Pampa, Portulaca guaritensis and Portulaca guenoa.

A plant–pollinator invasional meltdown: the Japanese pagoda tree Styphnolobium japonicum facilitates the invasion of the giant resin bee Megachile sculpturalis

Oikos, EarlyView.
An invasional meltdown can occur when a non‐native species facilitates the spread of another non‐native species in the invaded area, increasing its likelihood of survival or its ecological impact. Plant–pollinator systems pose an exceptional study system to test this concept, which remains poorly known.

Floral traits associated with low temperature tolerance at the young microspore stage in rice

Plant Production Science
Low temperature during the booting stage, particularly the young microspore stage (YMS), reduces pollen production and spikelet fertility in rice.

Unshared on the top: strong segregation of pathogen communities between western honey bees and wild bees in a retreating glacier foreland

Oikos, EarlyView.
Shared flowers can facilitate pathogen transmission between managed honey bees and wild bees, yet this process remains poorly understood in ecosystems undergoing rapid environmental change. Using a glacier foreland in Switzerland, we present the first study on how glacier retreat stages and bee life‐history traits influence pathogen occurrence across ...

The pistil as a traffic light: Yellow‐to‐red color change likely influences pollinator visitation patterns in Saxifraga fortunei (Saxifragaceae)

PLANTS, PEOPLE, PLANET, EarlyView.
Flowers can communicate reproductive status to pollinators through visual cues. In Saxifraga fortunei, pistils often changed from yellow to red after pollination, and hoverflies and honeybees preferentially visited flowers with yellow pistils. This pattern suggests that a post‐pollination color shift confined to the pistil can reduce revisits to ...

VARIABILIDAD EN RASGOS POLINICOS EN EL COMPLEJO MIMULUS LUTEUS L. (PHRYMACEAE) EN CHILE CENTRAL VARIABILITY OF POLLEN TRAITS IN THE MIMULUS LUTEUS L. (PHRYMACEAE) COMPLEX IN CENTRAL CHILE

Gayana: Botanica, 2004
We quantified the variability of pollen morphology and life history traits among three natural populations of two taxa in the Mimulus luteus complex and a group of putative hybrids that coexist in the Andean ranges of central Chile.
