A cornucopia of diversity-Ranunculales as a model lineage. [PDF]

J Exp Bot, 2023
Abstract The Ranunculales are a hyperdiverse lineage in many aspects of their phenotype, including growth habit, floral and leaf morphology, reproductive mode, and specialized metabolism. Many Ranunculales species, such as opium poppy and goldenseal, have a high medicinal value.

Heterodichogamy in Kingdonia (Circaeasteraceae, Ranunculales) [PDF]

Annals of Botany, 2012
Preliminary field observations in 2001 and 2002 suggested that Kingdonia uniflora (Circaeasteraceae, Ranunculales) exhibits heterodichogamy, an unusual kind of reproductive heteromorphy, hitherto unreported in Ranunculales and known from only one other genus in basal eudicots.During several subsequent years flowers were observed in the field.

Comparative floral development in Lardizabalaceae (Ranunculales) [PDF]

Botanical Journal of the Linnean Society, 2011
Abstract Ovules development and structure of 6 species of 5 genera in Lardizabalaceae were studied under SEM and LM. Ovule morphology show diversity in the family: anatropous ( Sinofranchetia and Decaisnea ) or campylotropous ( Sargentodoxa , Akebia and Holboellia ); ovule number is 1 ( Sargentodoxa ) to 20 (even up to 180 in Akebia and ...

Floral Morphogenesis in Euptelea (Eupteleaceae, Ranunculales) [PDF]

Annals of Botany, 2007
Based on molecular phylogenetic studies, the unigeneric family Eupteleaceae has a prominent phylogenetic position at or near the base of Ranunculales, which, in turn, appear at the base of eudicots. The aim of the present paper is to reveal developmental features of the flowers and to put the genus in a morphological context with other basal eudicots ...

Spermatophyta Molecular Clock: Time Drift and Recent Acceleration. [PDF]

Plant Environ Interact
Exponential increase in the base substitution rate in recent geologic time. ABSTRACT Angiospermae radiation is widely recognized as a mid‐Cretaceous event, but the adaptive radiation of Asarum and Viola as spring ephemerals also occurred during the Quaternary. To better understand the evolution of Angiospermae through geological time, a robust and well‐
