Outline of Angiosperm Phylogeny
Outline of angiosperm phylogeny: orders, families, and representative genera with emphasis on Oregon native plants Priscilla Spears December 2013 The following listing gives an introduction to the phylogenetic classification of the flowering plants that has emerged in recent decades, and which is based on nucleic acid sequences as well as morphological and developmental data. This listing emphasizes temperate families of the Northern Hemisphere and is meant as an overview with examples of Oregon native plants. It includes many exotic genera that are grown in Oregon as ornamentals plus other plants of interest worldwide. The genera that are Oregon natives are printed in a blue font. Genera that are exotics are shown in black, however genera in blue may also contain non-native species. Names separated by a slash are alternatives or else the nomenclature is in flux. When several genera have the same common name, the names are separated by commas. The order of the family names is from the linear listing of families in the APG III report. For further information, see the references on the last page. Basal Angiosperms (ANITA grade) Amborellales Amborellaceae, sole family, the earliest branch of flowering plants, a shrub native to New Caledonia – Amborella Nymphaeales Hydatellaceae – aquatics from Australasia, previously classified as a grass Cabombaceae (water shield – Brasenia, fanwort – Cabomba) Nymphaeaceae (water lilies – Nymphaea; pond lilies – Nuphar) Austrobaileyales Schisandraceae (wild sarsaparilla, star vine – Schisandra; Japanese

Things never stand still and one of the consequences of not doing Chelsea is that we no longer need some of the large show plants so this year we are able to offer the evergreen Dianella tasmanica (page 12) with its extraordinary blue berries. Some of our plants did not enjoy the wonderful summer as much as we did but the Schizostylis were an eye opener. They are stream side plants from southern Africa so we think of them as wanting dampish soils but forget that The youngest grandson - but Eucomis pole-evansii is winning! they experience seasonal rainfall and very hot summers. They literally blossomed and are still in full flower as I varieties are grown in an open field so we know they are write this in mid November.

JUDD W.S. Et. Al. (1999) Plant Systematics
CHAPTER8 Phylogenetic Relationships of Angiosperms he angiosperms (or flowering plants) are the dominant group of land Tplants. The monophyly of this group is strongly supported, as dis- cussed in the previous chapter, and these plants are possibly sister (among extant seed plants) to the gnetopsids (Chase et al. 1993; Crane 1985; Donoghue and Doyle 1989; Doyle 1996; Doyle et al. 1994). The angio- sperms have a long fossil record, going back to the upper Jurassic and increasing in abundance as one moves through the Cretaceous (Beck 1973; Sun et al. 1998). The group probably originated during the Jurassic, more than 140 million years ago. Cladistic analyses based on morphology, rRNA, rbcL, and atpB sequences do not support the traditional division of angiosperms into monocots (plants with a single cotyledon, radicle aborting early in growth with the root system adventitious, stems with scattered vascular bundles and usually lacking secondary growth, leaves with parallel venation, flow- ers 3-merous, and pollen grains usually monosulcate) and dicots (plants with two cotyledons, radicle not aborting and giving rise to mature root system, stems with vascular bundles in a ring and often showing sec- ondary growth, leaves with a network of veins forming a pinnate to palmate pattern, flowers 4- or 5-merous, and pollen grains predominantly tricolpate or modifications thereof) (Chase et al. 1993; Doyle 1996; Doyle et al. 1994; Donoghue and Doyle 1989). In all published cladistic analyses the “dicots” form a paraphyletic complex, and features such as two cotyle- dons, a persistent radicle, stems with vascular bundles in a ring, secondary growth, and leaves with net venation are plesiomorphic within angio- sperms; that is, these features evolved earlier in the phylogenetic history of tracheophytes.

The Plant Collection of the 6Th Earl of Coventry at Croome Park, Worcestershire
margaret stone, ann hooper, pamela shaw and lesley tanner an eighteenth-century obsession – the plant collection of the 6th earl of coventry at croome park, worcestershire The parkland at Croome, Worcestershire, was the frst landscape designed by Lancelot Brown, employed by George William, 6th Earl of Coventry. The Earl amassed a vast, diverse plant collection, for which over six hundred bills have survived; they cover more than sixty years from 1747 to his death in 1809. Large numbers of plants were purchased at enormous cost and there were many frst introductions to Britain. By the end of the eighteenth century this was arguably the fnest private collection ever formed. This paper is a study of that collection. in 1751, george william, viscount Deerhurst, succeeded to the title of 6th earl of coventry; he was twenty-eight years old and had been managing the croome estate for three years (figure 1). he had demolished the early eighteenth-century formal gardens and now employed lancelot brown as clerk of works to remodel the seventeenth- century house. brown had worked at stowe, buckinghamshire, for ten years between 1740 and 1751, acquiring experience in supervising building work and remodelling the lake; he was by then thirty-fve years old. the exterior of croome court shows considerable similarity to william kent’s neo-palladian holkham hall, norfolk. the earl must have been deeply involved in the project; he kept his invoices carefully, often annotating them, and they have survived to the present (figure 2).1 clearly, he had a good working relationship with brown, who was soon appointed to develop the grounds.

Networks in a Large-Scale Phylogenetic Analysis: Reconstructing Evolutionary History of Asparagales (Lilianae) Based on Four Plastid Genes
Networks in a Large-Scale Phylogenetic Analysis: Reconstructing Evolutionary History of Asparagales (Lilianae) Based on Four Plastid Genes Shichao Chen1., Dong-Kap Kim2., Mark W. Chase3, Joo-Hwan Kim4* 1 College of Life Science and Technology, Tongji University, Shanghai, China, 2 Division of Forest Resource Conservation, Korea National Arboretum, Pocheon, Gyeonggi- do, Korea, 3 Jodrell Laboratory, Royal Botanic Gardens, Kew, Richmond, United Kingdom, 4 Department of Life Science, Gachon University, Seongnam, Gyeonggi-do, Korea Abstract Phylogenetic analysis aims to produce a bifurcating tree, which disregards conflicting signals and displays only those that are present in a large proportion of the data. However, any character (or tree) conflict in a dataset allows the exploration of support for various evolutionary hypotheses. Although data-display network approaches exist, biologists cannot easily and routinely use them to compute rooted phylogenetic networks on real datasets containing hundreds of taxa. Here, we constructed an original neighbour-net for a large dataset of Asparagales to highlight the aspects of the resulting network that will be important for interpreting phylogeny. The analyses were largely conducted with new data collected for the same loci as in previous studies, but from different species accessions and greater sampling in many cases than in published analyses. The network tree summarised the majority data pattern in the characters of plastid sequences before tree building, which largely confirmed the currently recognised phylogenetic relationships. Most conflicting signals are at the base of each group along the Asparagales backbone, which helps us to establish the expectancy and advance our understanding of some difficult taxa relationships and their phylogeny.

This life form is common in the monocots that inhabit Mediterranean climates around the world. In Mexico only the northern area of Baja California has this type of climate. Hypothesis: In this study, we recorded the species and distribution of Mexican geophyte monocots to pinpoint diversity hot- spots. Our hypothesis is that the highest diversity of geophytes will be found in biogeographic areas with complex topography and seasonal climate not only in the north of the Baja California Peninsula. Data description: Records of geophytes were taken from different sources, collections, taxonomic references and diversity databases. Geophyte locations were mapped in the context of biogeographic and protected areas. Climate preferences were estimated using bioclimatic variables and by a Principal Component Analysis we identified the most significant variables explaining distribution of geophytes. Results: The Mexican geophyte flora is composed of 476 species, approximately 10 % of the total diversity of monocots. Echeandia and Tigridia were the two most diverse genera. This flora is dominated by the taxa of Orchidaceae, Asparagaceae and Iridaceae, and ten small endemic genera were recorded. Geophyte diversity was highest in two biogeographic provinces: the Trans-Mexican Volcanic Belt and the Sierra Madre del Sur, in dry forests such as oak-pine, seasonally dry tropical forests and semi-arid shrubby vegetation. Three bioclimatic variables: temperature seasonality, annual precipitation and precipitation of the wettest quarter resulted significant for understanding distribution of geophytes.

Email: [email protected] *Corresponding author SUMMARY Background: Tigridia pavonia (L.f.) DC is a wild species with great ornamental value, of which nine plant varieties are known. Within the evolutionary process of this species, Penélope has been considered a natural hybrid, product of the cross between the varieties Trinidad and Dulce. Objective: In the present study, the cytogenetic relationships among Trinidad, Dulce and Penélope were analyzed. Methodology: The karyotype of the varieties Trinidad and Penélope was determined through classic cytogenetics and the physical mapping of the genes 5s and 45s rDNA through Fluorescent In Situ Hybridization. Results: The results showed for the first time the karyotype and the physical mapping of the genes 5s and 45s rDNA in the varieties Trinidad and Penélope. Implications: The information generated can be the basis for future evolutionary analyzes, and / or breeding programs in the species. Conclusion: A higher cytogenetic similarity of Penélope with Trinidad and Dulce has been revealed, suggesting that the latter may be the parents.
