JOHNSTON CONTENTS The Species of Tournefortia and Messerschmidia in the Old World 145 Notes on Brand's Treatment of Cry New or otherwise Noteworthy Sj>e THE SPECIES treated here have, in the past, all been referred to the genus Tournefortia. I am, however, suggesting that certain of them be segregated to form the redefined genus Messerschmidia. During the work on this paper I have been privileged to examine almost all the type- specimens concerned. This has permitted me to place definitely a large number of poorly understood old species that have troubled workers in the past. The work has been undertaken as part of a projected study of the Boraginaceae-Heliotropioideae. It is the first attempt to treat all the Old World species of Tournefortia since the presentation by DeCandolle in the ninth volume of the Prodromus in 1845. Tournefortia Linnaeus, Sp. PI. 140 (1753) and Gen. PI. ed. 5, 68 (1754). The species of Tournefortia found in the Old World all belong to the following: Section EUTOURNEFORTIA Johnston, Contr.

Tetrandra (DC.) Miquel, Fl. Nederl. Ind. 2:928 (1858). — type- species, Tournejortia tetrandra Blume. The species of Eutourncjortia found in the Old World are remarkable for their parallelism of variation. Most of them have corollas with the tube either long or short, herbage with the pubescence present or absent, as well as leaf-blades that are broad or elongate. The combinations of these variations produce forms very diverse in gross appearance so that it is not at all surprising that botanists have been impressed by them and misled into giving specific names to many of them. A considera- tion of all the Old World Eutourtiejortiae and observation of the recur- rent pattern of variation among them, however, lead one to a proper estimate of the surprisingly diverse phases which they present. Like- wise, a consideration of the facts of distribution leads to a similar end. When the variations mentioned are given recognition it is found that the resulting numerous ill defined "species'' grow together over most of a common area of dispersal. When the variations mentioned are dis- counted, species may be defined that have a credible geographic range— a range that is distinct from that of the closely related species and one quite similar and familiar among species of other genera within the region. I am accordingly of the opinion that the variations noted deserve at best no more than mere formal recognition. Since, however, I do not believe that obscure tropical plants should be burdened with numerous subspecific names until some evident use for them arises, I have refrained from any attempt at formally naming the reoccurring combinations of the paralleling intraspecitic variation- described.

    Established 1990 PLANT LIST 2016 European mail order website www.crug-farm.co.uk CRÛG FARM PLANTS • 2016 Welcome to our 2016 list hope we can tempt you with plenty of our old favourites as well as some exciting new plants that we have searched out on our travels. There has been little chance of us standing still with what has been going on here in 2015. The year started well with the birth of our sixth grandchild. January into February had Sue and I in Colombia for our first winter/early spring expedition. It was exhilarating, we were able to travel much further afield than we had previously, as the mountainous areas become safer to travel. We are looking forward to working ever closer with the Colombian institutes, such as the Medellin Botanic Gardens whom we met up with. Consequently we were absent from the RHS February Show at Vincent Square. We are finding it increasingly expensive participating in the London shows, while re-branding the RHS February Show as a potato event hardly encourages our type of customer base to visit. A long standing speaking engagement and a last minute change of date, meant that we missed going to Fota near Cork last spring, no such problem this coming year. We were pleasantly surprised at the level of interest at the Trgrehan Garden Rare Plant Fair, in Cornwall. Hopefully this will become an annual event for us, as well as the Cornwall Garden Society show in April. Poor Sue went through the wars having to have a rush hysterectomy in June, after some timely results revealed future risks.
  • Well-Known Plants in Each Angiosperm Order

    Well-Known Plants in Each Angiosperm Order

    Well-known plants in each angiosperm order This list is generally from least evolved (most ancient) to most evolved (most modern). (I’m not sure if this applies for Eudicots; I’m listing them in the same order as APG II.) The first few plants are mostly primitive pond and aquarium plants. Next is Illicium (anise tree) from Austrobaileyales, then the magnoliids (Canellales thru Piperales), then monocots (Acorales through Zingiberales), and finally eudicots (Buxales through Dipsacales). The plants before the eudicots in this list are considered basal angiosperms. This list focuses only on angiosperms and does not look at earlier plants such as mosses, ferns, and conifers. Basal angiosperms – mostly aquatic plants Unplaced in order, placed in Amborellaceae family • Amborella trichopoda – one of the most ancient flowering plants Unplaced in order, placed in Nymphaeaceae family • Water lily • Cabomba (fanwort) • Brasenia (watershield) Ceratophyllales • Hornwort Austrobaileyales • Illicium (anise tree, star anise) Basal angiosperms - magnoliids Canellales • Drimys (winter's bark) • Tasmanian pepper Laurales • Bay laurel • Cinnamon • Avocado • Sassafras • Camphor tree • Calycanthus (sweetshrub, spicebush) • Lindera (spicebush, Benjamin bush) Magnoliales • Custard-apple • Pawpaw • guanábana (soursop) • Sugar-apple or sweetsop • Cherimoya • Magnolia • Tuliptree • Michelia • Nutmeg • Clove Piperales • Black pepper • Kava • Lizard’s tail • Aristolochia (birthwort, pipevine, Dutchman's pipe) • Asarum (wild ginger) Basal angiosperms - monocots Acorales

Two basic types of trichomes were recognized: eglandular and glandular. Eglandular trichomes are subdivided into simple and branched trichomes. Based on the number of cells and trichome configuration, simple eglandular trichomes are further divided into four forms: unicellular, two-celled, three-celled and more than three-celled trichomes. Based on branching configuration, the branched eglandular trichomes can be separated into three forms: biramous, stellate and dendroid. Glandular trichomes can be divided into two subtypes: capitate and peltate glandular trichomes. Results from this study of morphological diversity of trichomes within Colquhounia lend insight into infrageneric classification and species relationships. Based on the presence of branched trichomes in C. elegans,thisspecies should be transferred from Colquhounia sect. Simplicipili to sect. Colquhounia. We provide a taxonomic key to species of Chinese Colquhounia based on trichome morphology and other important morphological traits. Key words: Colquhounia; glandular hairs; leaf anatomy; Lamioideae; Yunnan Introduction in spikes or capitula; equally 5–toothed calyces; and nutlets winged at apex (Li & Hedge 1994).

    Boraginales) Based on Trnl and ITS1 Sequence Data7

    6 Systematic analysis of Heliotropiaceae based on trnL and ITS1 sequences 6 A systematic analysis of Heliotropiaceae (Boraginales) 7 based on trnL and ITS1 sequence data Summary The infrafamilial relationships of Heliotropiaceae (Boraginaceae subfam. Heliotropioideae according to classical systems) are reevaluated using molecular data of nuclear ITS1 (86 species) and plastidal trnLUAA intron (66 species) sequences. The results obtained from our investigations show that traditional generic limits warrant adjustment. Heliotropiaceae fall into two large clades. The first clade includes, in basal position, the genus Ixorhea. The genus Myriopus (formerly Tournefortia sect. Cyphocyema) is sister to Euploca (formerly Hilgeria, Schleidenia, Heliotropium sect. Orthostachys). The remaining sections of Heliotropium, Tournefortia sect. Tournefortia and the three small genera Argusia, Ceballosia, and Nogalia, segregated from Heliotropium, constitute the second large clade. Argusia, Ceballosia, and Nogalia cluster within clades of Heliotropium and therefore are reincluded into this genus. Within Heliotropium the species of former Tournefortia sect. Tournefortia represent a lineage of tropical New World Heliotropium species, growing in humid environments, whereas all other Heliotropium species are found in semi-arid habitats. Before new combinations in the genus Heliotropium are made for “Tournefortia”, the exact relationship within New World Heliotropium needs to be resolved, and a revision of “Tournefortia” is inevitable. We advocate maintain the genus Tournefortia, which is easily to define and we conclude that under this definition the genus Heliotropium is paraphyletic. Five genera are thus accepted; 22 new combinations within Heliotropiaceae are presented. 7 Manuscript submitted as HILGER H.H. & DIANE N.

A few of these were not happy in their location and promptly died, or did so poorly as to warrant their removal. A few new varie- ties were added to the original group, but for the most part these trees have been growing there s~nce the trial plot was first laid out. The collection has been of special interest to home owners in the suburban areas of Boston, who naturally are interested in small ornamental trees. It has also been of considerable interest to the tree wardens of various towns throughout New England, for here one may see many of the best small trees growing side by side, so that comparisons can be easily made. Recently this plot has been of interest to the Electric Council of New England, a group of utility companies which provide various electric services for the public in addition to stringing electric lines for these services. When the right kinds of trees are planted properly in the right places along the streets and highways, there need be but little competition between the trees and the wires.

II. Some denominations of Dicotyledonous Trees and Shrubs species. With a Retrospection and a set of Propositions on the Nomenclature-Rules BY Dr. J. VALCKENIER SÜRINGAR, retired prof, of the Agricultural Academy in the Netherlands. INTRODUCTION. This second Part has its origin principally in Dr. ALFRED REHDER'S "Manual of Cultivated Trees and Shrubs" 1927. That admirable work contains several revolutionary looking changes of names, which changes partly were already propagated in BAILEY'S works of the last years; and I have made a study of those names, beside others. The result is that I cannot in many cases join with REHDER'S new-old names and principles. But when I therefore criticise in all those cases REHDER'S opinion, the reader must not think thereby that I criticise REHDER'S work as a whole. I criticise the names and principles only because I think that these changes and principles are unfavourable with respect to the world's effort to obtain unity of plantnomenclature; and I don't think about criticizing the work as a whole. REHDER'S "Manual" is the result of long and arduous work; it is in its relative size the most complete, the sharpest as to the characters, the newest and most usable of all Dendrological works existing. No Dendrologist, even no Botanist, who has to do with Trees and Shrubs, can do without it. Readers, who wish eventually to obtain corrigenda and addenda to this paper or to the first part of it, are requested to communicate with the writer, who will be moreover thankful for hints and observations.

    Woody and Herbaceous Plants Native to Haiti for Use in Miami-Dade Landscapes1

    Woody and Herbaceous Plants Native to Haiti For use in Miami-Dade Landscapes1 Haiti occupies the western one third of the island of Hispaniola with the Dominican Republic the remainder. Of all the islands within the Caribbean basin Hispaniola possesses the most varied flora after that of Cuba. The plants contained in this review have been recorded as native to Haiti, though some may now have been extirpated due in large part to severe deforestation. Less than 1.5% of the country’s original tree-cover remains. Haiti’s future is critically tied to re- forestation; loss of tree cover has been so profound that exotic fast growing trees, rather than native species, are being used to halt soil erosion and lessen the risk of mudslides. For more information concerning Haiti’s ecological plight consult references at the end of this document. For present purposes all of the trees listed below are native to Haiti, which is why non-natives such as mango (the most widely planted tree) and other important trees such as citrus, kassod tree (Senna siamea) and lead tree (Leucanea leucocephala) are not included. The latter two trees are among the fast growing species used for re-forestation. The Smithsonian National Museum of Natural History’s Flora of the West Indies was an invaluable tool in assessing the range of plants native to Haiti. Not surprisingly many of the listed trees and shrubs 1 John McLaughlin Ph.D. U.F./Miami-Dade County Extension Office, Homestead, FL 33030 Page | 1 are found in other parts of the Caribbean with some also native to South Florida.

    Lamiales – Synoptical Classification Vers

    Lamiales – Synoptical classification vers. 2.6.2 (in prog.) Updated: 12 April, 2016 A Synoptical Classification of the Lamiales Version 2.6.2 (This is a working document) Compiled by Richard Olmstead With the help of: D. Albach, P. Beardsley, D. Bedigian, B. Bremer, P. Cantino, J. Chau, J. L. Clark, B. Drew, P. Garnock- Jones, S. Grose (Heydler), R. Harley, H.-D. Ihlenfeldt, B. Li, L. Lohmann, S. Mathews, L. McDade, K. Müller, E. Norman, N. O’Leary, B. Oxelman, J. Reveal, R. Scotland, J. Smith, D. Tank, E. Tripp, S. Wagstaff, E. Wallander, A. Weber, A. Wolfe, A. Wortley, N. Young, M. Zjhra, and many others [estimated 25 families, 1041 genera, and ca. 21,878 species in Lamiales] The goal of this project is to produce a working infraordinal classification of the Lamiales to genus with information on distribution and species richness. All recognized taxa will be clades; adherence to Linnaean ranks is optional. Synonymy is very incomplete (comprehensive synonymy is not a goal of the project, but could be incorporated). Although I anticipate producing a publishable version of this classification at a future date, my near- term goal is to produce a web-accessible version, which will be available to the public and which will be updated regularly through input from systematists familiar with taxa within the Lamiales.
