Species distribution models predict Lippia turbinata and Salimenaea integrifolia (Verbenaceae) could expand their ranges by 2070 while Lippia alba may lose habitat. Contrasting responses show the need for species-specific conservation strategies to protect plant resources.

A new orchid, Telipogon villonacoensis, is described from the Andes. Once thought restricted to southern Ecuador, it is now known from Colombia to Peru, which is an unusually wide range for the genus. This discovery sheds light on the hidden diversity of miniature orchids.

A new species of carnivorous plant, Pinguicula panfetiae, has been described from eastern Cuba. Endemic to the slopes of the River Toa in the Alejandro de Humboldt National Park, it differs from related species by its smaller white flowers and leaf shape.

A new set of 48 nuclear microsatellite markers (14 polymorphic) was developed for Cola acuminata, an important African food tree. Results indicate high genetic diversity, and the markers also proved transferable to C. nitida.

Hedgerows play a crucial ecological role in maintaining connectivity in the fragmented Atlantic Forest. This study showed hedgerows matched forest fragments in seed rain and litter, with even greater fruit richness, highlighting their role in biodiversity conservation.

The allohexaploid genus Campeiostachys (StYH) originated from natural hybridization between tetraploid Roegneria (StY) and diploid Hordeum (H), with Roegneria as the maternal donor. The study also shows that C. purpuraristata belongs in the C. dahurica complex.

Wild Vigna marina shows remarkable salt tolerance, surviving up to 20,000 ppm NaCl, outperforming commercial Vigna radiata varieties. Populations differ widely, making their conservation crucial for breeding salt-tolerant crops in a changing climate.

Symmetry vs structure in naviculoid diatoms. This review shows how SEM & wall morphogenesis studies reshaped our understanding: structure, not symmetry, underpins true relationships. Valve shape and symmetry still matter but beware of overemphasising single traits.

Background and aims – Over 40 years ago, I explored the use of symmetry and structure as taxonomic criteria for naviculoid diatoms, arguing that structure was the more informative character. This paper examines subsequent progress in the understanding and systematics of naviculoid diatoms with par...
