Abstract The study of fossil plant–biotic (mainly arthropod) interactions offers an opportunity to understand the evolutionary process in palaeoecosystems and their response to climate fluctuation. Despite the importance of such investigations, not much is known about plant–arthropod associations from the Cenozoic floras of Asia.

Abstract Wetlands are very fragile systems and susceptible to being affected by human activity. S'Albufera de Mallorca Natural Park is the main wetland in Mallorca Island (Spain), and undergoes a salinization process derived from the overexploitation of adjacent aquifers, which favors marine intrusion.

Phytotaxa
Two new species are described and illustrated. Echeveria cuevasii shares with E. flammigera typical characteristics of Echeveria of the Nudae series, for instance, a subshruby habit, medium-sized rosettes and short sub spicate inflorescences. However, it differs from the latter by having fewer shorter branches, longer leaves, more flowers per ...

Systematic Botany, 2007
Most floral diversity in the core eudicots is based on a groundplan that includes among its most distinctive elements a bipartite perianth and pentamerous merosity combined with a bicarpellate gynoecium. To obtain insights into the origins of this groundplan, the evolution of its structural components in Hamamelidoideae (Hamamelidaceae, Saxifragales ...

A cladistic analysis was performed including five Cretaceous and 31 extant taxa within Saxifragales using a combination of molecular sequence and morphological data in order to elucidate the utility of extinct taxa in illuminating saxifragalean evolution.

The Botanical Review, 2013
Itea is a genus of about 20 species of trees and shrubs that are today native to southeastern North America, eastern Asia, and eastern Africa. In this paper, I review the fossil record of Itea, which is based on four types of fossils: diporate, psilate pollen attributed to Itea or the dispersed pollen genus Iteapollis; carpofossils representing fruits ...
