Nordic Journal of Botany, EarlyView.Names in the genus Pinguicula established for taxa from the Baltic and Nordic countries, including their oversea territories and Iceland, were analyzed to provide nomenclatural and taxonomic clarity. Of the 33 names retrieved from the literature and online databases, one is illegitimate, two are invalid and 16 were found to require typification.

Extrafloral nectar fuels ant life in deserts [PDF]
, 2014 Interactions mediated by extrafloral nectary (EFN)-bearing plants that reward ants with a sweet liquid secretion are well documented in temperate and tropical habitats. However, their distribution and abundance in deserts are poorly known. In this study,

THE ECOLOGY OF MUTUALISM [PDF]
, 1982 Elementary ecology texts tell us that organisms interact in three fundamen tal ways, generally given the names competition, predation, and mutualism. The third member has gotten short shrift (264), and even its name is not generally agreed on.

Calyx and epicalyx morphology in Indian Hibiscus (Malvaceae) and its taxonomic importance
Nordic Journal of Botany, EarlyView.Hibisceae is one of the largest tribes in Malvaceae, having a diverse floral morphology. The genus Hibiscus shows a wide range of evolutionary patterns in calyx and epicalyx morphology. Genera like Abelmoschus, Azanza, Gossypium, Hibiscus,and Thespesia are separated on the basis of calyx and epicalyx morphology, meaning that the calyx and epicalyx have
