Journal ArticleDOI
TL;DR: A formal classification of the land plants that is compatible with the APG III classification is proposed, and two new names are established: Amborellanae and Austrobaileyanae.

338 citations


Journal ArticleDOI
TL;DR: A new subfamilial name, Xanthorrhoeoideae, and a new tribal name, Oziroeeae, are proposed, which greatly simplifies the taxonomy of Asparagales and thus makes the teaching of these families much easier.

283 citations


Journal ArticleDOI
TL;DR: Ford et al. as mentioned in this paper proposed a method for selection of candidate coding DNA barcoding regions for use on land plants, based on the Linnean Society International Journal of Botanical Sciences (BLINSE).

254 citations


Journal ArticleDOI
TL;DR: The publication of the third Angiosperm Phylogeny Group (APG) classification has resulted in the need for a revised systematic listing of the accepted families, and this linear APG III (LAPG III) sequence of families is presented here.

178 citations


Journal ArticleDOI
TL;DR: How Darwin's seminal work on the angraecoid orchid Angraecum sesquipedale triggered the beginning of a long debate about the evolution of long floral spurs and why his idea of reciprocal evolution or ‘coevolution’ was one of the great contributions to evolutionary biology is discussed.

103 citations


Journal ArticleDOI
TL;DR: Differences in proportions of parts of the ovules in Anacardiaceae and Burseraceae are linked with the different direction of ovule curvature, which may represent a synapomorphy or apomorphic tendency for the three families.

90 citations


Journal ArticleDOI
TL;DR: Xylem heterochrony is analysed not only for all key groups of angiosperms (including monocots), but also for different growth forms, such as lianas, annuals, various types of perennials, rosette trees and stem succulents.

84 citations


Journal ArticleDOI
TL;DR: The various angiosperm clades in which carnivory has evolved and the degree to which these plants have become ‘complete carnivores’ is documented and the problems with definition of the terms used to describe carnivorous plants are discussed.

75 citations


Journal ArticleDOI
TL;DR: The anatomical leaf structure was consistent throughout the Mentheae tribe, and the vascular bundles in the midrib were modified into a mechanical tissue, which is an adaptation to xerophytic environments.

Journal ArticleDOI
TL;DR: It is suggested that the papillae improve pollination because they are a tactile expectation of pollinating insects, and the prominence of striations may be a 'spandrel', simply reflecting the thickness of the overlying cuticle.

Journal ArticleDOI
TL;DR: The elaiophore on the internal surface of the lip produces oil in non-collectible amounts, but it is enough to maintain the interest of the bees, guiding them to the elaiophile on the column base, a necessary step in pollination.

Journal ArticleDOI
TL;DR: The date estimates suggest that the most recent common ancestor of Begonia could have diversified from the end of the Cretaceous to the beginning of the Neogene, probably during a period of global cooling from the mid Eocene to early Oligocene.

Journal ArticleDOI
TL;DR: The Oceanian plant genus Spiraeanthemum (Cunoniaceae) has a centre of diversity in New Caledonia, where it is represented by seven species and its diversification was investigated using two low-copy nuclear genes, ncpGS and GapC, and phylogenetic analyses were based on maximum parsimony, maximum likelihood and recombination networks.

Journal ArticleDOI
TL;DR: Heterostyly is now known to occur in many more plant families than at the time Forms of Flowers was published and, as expected, the heterostylous syndrome is now defined more broadly than in Darwin's time.

Journal ArticleDOI
TL;DR: High levels of genetic diversity maintained in populations of C. macranthos suggest that the collection-mediated decrease in the number of individuals is still too recent for long-term effects on genetic variation, and in situ and ex situ conservation strategies should be provided to preserve genetic variation and to ensure the long- term survival of the two species in the Korean Peninsula.

Journal ArticleDOI
TL;DR: In this paper, the glandular origin of the stipular colleters in Ilex is confirmed on the basis of their position, secretions and anatomy, and proteins were found in the secretions studied.

Journal ArticleDOI
TL;DR: It is demonstrated that the distribution of epidermal silica bodies is homoplastic within Pteridaceae, but that they act as a potential synapomorphies for several different groups within the family.

Journal ArticleDOI
TL;DR: It seems that a low frequency of hybrid formation can function as an important mechanism of reproductive isolation between closely related pairs of species in the A. nidus complex in addition to hybrid sterility.


Journal ArticleDOI
TL;DR: A critical morphological analysis of living populations and extensive herbarium material, together with karyological, cytogenetical and DNA-analytical data allow a discussion of the phylogenetic diversification and stepwise expansion of the section since the late Miocene.

Journal ArticleDOI
TL;DR: The data indicate that hybridization and introgression are common in all these species on Tenerife and support the hypothesis that homoploid hybrid speciation has occurred repeatedly, and examine population differentiation based on amplified fragment length polymorphism.

Journal ArticleDOI
TL;DR: The effects of after-ripening (storage under warm, dry conditions) on seed germination was examined in six plant species from the arid zone of Western Australia with the aim of improving germination and germination rate for rehabilitation objectives.

Journal ArticleDOI
TL;DR: Assessment of morphological variation in the V. paraibica complex led to the selection of diagnostic traits of four species, including red and yellow floral bracts of V. interrogatoria and V. eltoniana.

Journal ArticleDOI
TL;DR: A new species of Nepenthes L., N. attenboroughii (Nepenthaceae), from Palawan Island in the Philippines, is described and illustrated, and appears to be related to both N. mira Jebb & Cheek of Palawan and N. rajah Hook.

Journal ArticleDOI
TL;DR: It is concluded that section Camellia consists of c.

Journal ArticleDOI
TL;DR: It is hypothesize that O. mesaritica may have arisen from O. iricolor by pollinator shift and that this is more probable than scenarios invoking hybridization as a result of mispollination by rare, non-specific flower visitors or specifically attracted insects.

Journal ArticleDOI
TL;DR: A phylogenetic analysis using published sequences of the plastid rbcL and ndhF genes, the trnL-trnF region and the nuclear ribosomal internal transcribed spacer (ITS) to assess the systematic placement of the two genera within Mutisioideae showed that Gypothamnium is closely related to Leucheria, Moscharia, Polyachyrus and, with low support, Jungia.

Journal ArticleDOI
TL;DR: This study revealed that molecular, morphological and karyological data reveal similar patterns in the taxa studied, and suggests that Bunium spp.
