ConclusionIn conclusion I wish to pay deserved tribute to two men for their outstanding contributions to the general system of plants during the twentieth century. Adolf Pascher’s extensive and critical work on the algae, culminating in a general system (1931), is the foundation and inspiration for all modern algological systems. Charles E. Bessey is usually remembered for his well known work on the phylogeny and classification of angiosperms, especially as expressed in papers published in 1897… Expand
Replacement Name for Tetradium DANA, 1846
TLDR
It was shown recently that Tetradium Dana, 1846, a common Middle and Upper Ordovician fossil, is a calcareous filamentous florideophyte alga (Phylum Rhodophyta) and not a tabulate coral or a chaetetid sponge, as traditionally classified. Expand
A PHYLOGENETIC CLASSIFICATION OF THE ANNONIFLORAE Ro
A synoptical key to the three orders Annonales, Berberidales, and Nymphaeales of the superorder Annoniflorae is presented with discussion as to why these orders, the core of the histmical Ranales,Expand
A new view on Nematothallus: coralline red algae from the Silurian of Gotland
TLDR
The Nematothallopsis organism is reconstructed as an extinct rhodophyte and the putative terrestrial habit of cuticular nematophytes in general is re-evaluate to reflect the conspicuous similarity of the palisades to the pseudoparenchymatous tissue of coralline red algae. Expand
The taxonomy of middle Miocene red algae from the Gârbova de Sus Formation (Transylvanian Basin, Romania)
TLDR
This study describes seventeen non-geniculate coralline algal species from the middle Miocene (lower-middle Badenian) red-algal limestones of the Transylvanian Basin, Gârbova de Sus Formation and proposes the attribution of Lithophyllum platticarpum Maslov to Spongites fruticulosus Kutzing as a gametangial thallus with male conceptacles. Expand
Lithothamnion crispatum: long-lasting species of non-geniculate coralline algae (Rhodophyta, Hapalidiales)
TLDR
The examination of fossil Lithothamnion specimens ranging in age from the Early Miocene to the Pleistocene revealed the occurrence of multiporate conceptacle chambers pitted with depressions, indicating this species has a long stratigraphic distribution starting at least 20 My ago, without significant morphological changes in either reproductive or vegetative anatomy. Expand
Grateloupia Serra sp. nov. H. W. Wang & Y. Lou (Halymeniaceae, Rhodophyta): a new species previously confused with Grateloupia asiatica in China
TLDR
Morphological differences were supported by molecular analyses based on ribulose-1, 5-bisphosphate carboxylase/oxygenase gene (rbcL) sequences and Sequences of four G. serra sp. Expand
Two New Records of Peyssonnelia Species and Sonderophycus cauliferus Comb. Nov. within the Family Peyssonneliaceae (Peyssonneliales) from Korea
TLDR
Detailed morphological studies and molecular analyses based on plastid-encoded rbcL gene sequences were undertaken on Peyssonnelia species, a poorly known genus from Korea, and a new combination, Sonderophycus cauliferus comb is proposed, for previous Peysonnelia caulifera. Expand
An assessment of the taxonomic status of the Mediterranean endemic genus Acrodiscus Zanardini (Halymeniales, Rhodophyta)
TLDR
This study extensively sampled A. vidovichii and documented its vegetative and tetrasporangial features, and provides molecular-sequence data (COI-5P, rbc L, LSU) that indicate its phylogenetic affinities. Expand
Identification of Phymatolithon lamii (Me. Lemoine) Y.M. Chamberlain 1991 following bleaching in the upper intertidal zone of the Minas Basin, Nova Scotia, Canada
Objective: To identify an unusual encrusting calcareous organism found growing on upper intertidal rocks along the coast of the Minas Basin, Nova Scotia, Canada, which was thought to potentiallyExpand
Molecular phylogenies support taxonomic revision of three species of Laurencia (Rhodomelaceae, Rhodophyta), with the description of a new genus
The systematics of the Laurencia complex was investigated using a taxon-rich data set including the chloroplast ribulose-1,5-bisphosphate carboxylase/oxygenase large subunit ( rbc L) gene only and aExpand

ORIGINS OF ANGIOSPERMOUS PLANTS
TLDR
The principal conclusions reached by Takhtajian are that the angiosperms originated in the Jurassic or perhaps the Triassic period and persisted as subordinate elements of the flora until mid-Cretaceous time, when they rapidly rose to dominance. Expand
Gymnosperms
the field to the economic zoologist and entomologist who are only secondarily interested in the affected plant. Nine chapters (I76 pages) are devoted to nonparasitic diseases; one chapter (55 pages)Expand
Cryptogamic Botany
THE utility of a book presenting in clear outline the present state of our knowledge of the morphology of flowerless plants cannot be doubted. The division of plants into Cryptogams and PhanerogamsExpand
Classification of Gymnosperms from the Viewpoint of Paleobotany
TLDR
An altered scheme of classification of the vascular plants is proposed in which the "gymnosperms" are parceled among three classes in accordance with affinities as suggested by their origin. Expand
Studies in Fossil Botany
THE present work owes its origin to a course of lectures delivered at University College in 1896. In appealing to a wider audience, Dr. Scott has rendered an important service to biological science,Expand
On the Morphology and Relationships on the Taxaceae
TLDR
The Cephalotaxaceae are still variously treated, viz., as a group of the farnily Taxaceae or as a family of their own, either placed close to the yew family or regarded as of very different phylogenetic origin. Expand
On the Broad Classification of Organisms
  • R. Whittaker

A system of broad classification which recognized a plant kingdom of four divisions and an animal kingdom of ten to fifteen phyla was for many years stable and standardized. Significant changes haveExpand
The Structure And Development Of The Stem In The Pteridophyta And Gymnosperms
TLDR
A comparison of the taxonomic criteria employed for the higher animals and the higher plants respectively results in a striking contrast, which will serve to illustrate the value of the primary fibrovascular skeleton from the phylogenetic standpoint. Expand
On the Structure and Affinities of Acmopyle Pancheri, Pilger
TLDR
An investigation of some material collected in New Caledonia by Prof. R. Compton, M. A., during his expedition to that island in 1914 is undertaken. Expand
A new system of the Cormophyta
TLDR
It is justified to briefly review the results at which I arrived in the present journal to explain one or two points of a nomenclatural nature which, it seems to me, were perhaps somewhat insufficiently elucidated in the paper quoted. Expand
