RAIMONDO Dipartimento STEBICEF/ Sezione di Botanica ed Ecologia vegetale, Via Archirafi 38, I-90123 Palermo. ABSTRACT. – Record of Talinum paniculatum (Talinaceae) naturalized in Sicily. – The record in the urban context of Palermo (Sicily) of Talinum paniculatum, species native to Tropical America and mainly cultivated for ornamental purposes, is reported. It is the first case of naturalization in the Island of a species of Talinaceae family introduced to Palermo in 1984 from Argentina and cultivated in the Botanical Garden collections. Key words: Talinum, alien flora, Mediterranean plants, Sicily. PREMESSA Il genere Talinum Adans.

Entre ellos, las abejas constituyen un eslabón esencial en la polinización de angiospermas que durante millones de años desarrollaron estrategias cada vez más específicas para atraerlas. De esta forma se establece una relación muy fuerte entre am- bos, planta-polinizador, y cuanto mayor es la especialización, tal como sucede en un gran número de especies de orquídeas y cactáceas entre otros grupos, ésta se torna más vulnerable ante cambios ambientales naturales o producidos por el hombre. De esta forma, el estudio de este tipo de interacciones resulta cada vez más importante en vista del incremento de áreas perturbadas o modificadas de manera antrópica en las cuales la fauna y flora queda expuesta a adaptarse a las nuevas condiciones o desaparecer. -

AN ANNOTATED VASCULAR FLORA AND FLORISTIC ANALYSIS OF THE SOUTHERN HALF OF THE NATURE CONSERVANCY DAVIS MOUNTAINS PRESERVE, JEFF DAVIS COUNTY, TEXAS, U.S.A. Jeffrey James Keeling Sul Ross State University Box C-64 Alpine, Texas 79832-0001, U.S.A. [email protected] ABSTRACT The Nature Conservancy Davis Mountains Preserve (DMP) is located 24.9 mi (40 km) northwest of Fort Davis, Texas, in the northeastern region of the Chihuahuan Desert and consists of some of the most complex topography of the Davis Mountains, including their summit, Mount Livermore, at 8378 ft (2554 m). The cool, temperate, “sky island” ecosystem caters to the requirements that are needed to accommo- date a wide range of unique diversity, endemism, and vegetation patterns, including desert grasslands and montane savannahs. The current study began in May of 2011 and aimed to catalogue the entire vascular flora of the 18,360 acres of Nature Conservancy property south of Highway 118 and directly surrounding Mount Livermore. Previous botanical investigations are presented, as well as biogeographic relation- ships of the flora. The numbers from herbaria searches and from the recent field collections combine to a total of 2,153 voucher specimens, representing 483 species and infraspecies, 288 genera, and 87 families. The best-represented families are Asteraceae (89 species, 18.4% of the total flora), Poaceae (76 species, 15.7% of the total flora), and Fabaceae (21 species, 4.3% of the total flora). The current study represents a 25.44% increase in vouchered specimens and a 9.7% increase in known species from the study area’s 18,360 acres and describes four en- demic and fourteen non-native species (four invasive) on the property. -

Disintegrating Portulacaceae: a new familial classification of the suborder Portulacineae (Caryophyllales) based on molecular and morphological data Abstract Traditional classifications of the suborder Portulacineae recognize six families: Basellaceae, Cactaceae, Didiereaceae, Halophytaceae, Hectorellaceae, and Portulacaceae. However, phylogenetic analyses based on molecular sequence data indicate that the traditional family Portulacaceae is paraphyletic and consists of three distinct lineages that also include Cactaceae, Didiereaceae, and Hectorellaceae. We use sequence data from the chloroplast genes matK and ndhF representing 64 species of Portulacineae and outgroups to reconstruct their phylogenetic relationships with Bayesian and maximum parsimony inference methods. Evidence from these molecular phylogenetic analyses as well as from comparative morphological investigations allow us to propose a revised familial classification of the suborder Portulacineae. -
2 ANGIOSPERM PHYLOGENY GROUP (APG) SYSTEM History Of
ANGIOSPERM PHYLOGENY GROUP (APG) SYSTEM The Angiosperm Phylogeny Group, or APG, refers to an informal international group of systematic botanists who came together to try to establish a consensus view of the taxonomy of flowering plants (angiosperms) that would reflect new knowledge about their relationships based upon phylogenetic studies. As of 2010, three incremental versions of a classification system have resulted from this collaboration (published in 1998, 2003 and 2009). An important motivation for the group was what they viewed as deficiencies in prior angiosperm classifications, which were not based on monophyletic groups (i.e. groups consisting of all the descendants of a common ancestor). APG publications are increasingly influential, with a number of major herbaria changing the arrangement of their collections to match the latest APG system. Angiosperm classification and the APG Until detailed genetic evidence became available, the classification of flowering plants (also known as angiosperms, Angiospermae, Anthophyta or Magnoliophyta) was based on their morphology (particularly that of the flower) and their biochemistry (what kinds of chemical compound they contained or produced). Classification systems were typically produced by an individual botanist or by a small group. The result was a large number of such systems (see List of systems of plant taxonomy). Different systems and their updates tended to be favoured in different countries; e.g. the Engler system in continental Europe; the Bentham & Hooker system in Britain (particularly influential because it was used by Kew); the Takhtajan system in the former Soviet Union and countries within its sphere of influence; and the Cronquist system in the United States. -

DDC) Stemming from the Adoption of the APG (Angiosperm Phylogeny Group) III Classification As the Basis for the DDC’S Treatment of Flowering Plants
This PDF documents proposed changes throughout the Dewey Decimal Classification (DDC) stemming from the adoption of the APG (Angiosperm Phylogeny Group) III classification as the basis for the DDC’s treatment of flowering plants. We request comment from any interested party, to be sent to Rebecca Green ([email protected]) by 31 January 2016. Please include “Angiosperm review comments” in your subject line. -------------------------------------------------------------- Why is the DDC adopting a new basis for classifying angiosperms (flowering plants)? During the latter half of the 20th century, biological classification turned from establishing taxa predominantly on the basis of morphological similarities to establishing taxa predominantly on the basis of shared ancestry / shared derived characters, with biological taxonomies mirroring evolutionary relationships. Phylogenetic analysis typically underlies modern evolutionary classifications, but has resulted in the development of many competing classifications. Within the domain of flowering plants, different classification systems have been favored in different countries. The Angiosperm Phylogeny Group, a global consortium of botanists, has addressed this issue by developing a “consensus” classification that is monophyletic (i.e., its taxa include all but only the descendants of a common ancestor). Now in its third version, the APG III classification is considered relatively stable and useful for both research and practice (e.g., for organizing plants in herbaria). The development for flowering plants presented here is the culmination of DDC editorial work over a span of several years. An early version revised 583–584 to make the schedule compatible with the APG III classification, while trying to minimize relocations and using see references to establish the APG III logical hierarchy. -

(Received: 19th May, 2019; Accepted: 28th December, 2019) ABSTRACT Leaf anatomical studies were carried out on two species of Talinum: Talinum triangulare (Jacq.) Willd and Talinum paniculatum (Jacq.) Gaertn to fill the knowledge gap in the understanding of the taxonomic relationship between the two species of the genus Talinum studied. Widens of T. paniculatum were collected and established in nursery bags in Ondo city, Ondo State, Nigeria. At flowering, the leaves were collected for anatomical studies. Free hand peeling was done for leaf portions that were used for epidermal studies. Leaves were cleared for venation using standard methods. Transverse sections of the leaf blade, mid rib and petiole were cut from the median portion of the materials available using Reicheirt sliding microtome at 8 - 15 µm. Sections were stained in Safranin O and counter stained in Alcian blue. These were rinsed in several water changes to remove excess stain and then treated to serial grades of alcohol. The stained sections were mounted in dilute glycerol for anatomical studies. Observations were made with compound light microscope. -
