We propose a method for seed shape quantification based on the comparison of the bi-dimensional images of the seeds with geometric figures. J index is the percent of similarity of a seed image with a figure taken as a model. Models in shape quantification include geometrical figures (circle, ellipse, oval ::: ) and their derivatives, as well as other figures obtained as geometric representations of algebraic equations. The analysis is based on three sources: Published work, images available on the Internet, and seeds collected or stored in our collections. Some of the models here described are applied for the first time in seed morphology, like the superellipses, a group of bidimensional figures that represent well seed shape in species of the Calamoideae and Phoenix canariensis Hort. ex Chabaud. -

In order to characterize the inflorescence and further knowledge of this family, a morphoanatomical study was carried out of the palm S. inajai in a green area of the Campus of the Federal University of Amazonas - UFAM, Manaus, Amazonas. The inflorescences are branched to one order, pedunculate, and interfoliar, measuring 62-82 cm in length, with woody bracts with longitudinal grooves on the external surface, and flowers in triads. The number of flowers to each inflores- cence varies from 5,904 to 17,316 for staminate flowers, and from 180 to 3,528 for pistillate flowers. Staminate flowers with six anthers and one vascular bundle each; three-lobed pistillodium, vascularized pistillodium. Its pistillate flowers have six staminodia joined to form a circle, syncarpic, tricarpellary, trilocular gynoecium, one ovule to each locule, synascidiate in the ovary, and plicated above. -

Systematics and Evolution of the Rattan Genus Korthalsia Bl
SYSTEMATICS AND EVOLUTION OF THE RATTAN GENUS KORTHALSIA BL. (ARECACEAE) WITH SPECIAL REFERENCE TO DOMATIA A thesis submitted by Salwa Shahimi For the Degree of Doctor of Philosophy School of Biological Sciences University of Reading February 2018 i Declaration I can confirm that is my own work and the use of all material from other sources have been properly and fully acknowledged. Salwa Shahimi Reading, February 2018 ii ABSTRACT Korthalsia is a genus of palms endemic to Malesian region and known for the several species that have close associations with ants. In this study, 101 new sequences were generated to add 18 Korthalsia species from Malaysia, Singapore, Myanmar and Vietnam to an existing but unpublished data set for calamoid palms. Three nuclear (prk, rpb2, and ITS) and three chloroplast (rps16, trnD-trnT and ndhF) markers were sampled and Bayesian Inference and Maximum Likelihood methods of tree reconstruction used. The new phylogeny of the calamoids was largely congruent with the published studies, though the taxon sampling was more thorough. Each of the three tribes of the Calamoideae appeared to be monophyletic. The Eugeissoneae was consistently resolved as sister to Calameae and Lepidocaryeae, and better resolved, better supported topologies below the tribal level were identified. Korthalsia is monophyletic, and novel hypotheses of species level relationships in Korthalsia were put forward. These hypotheses of species level relationships in Korthalsia served as a framework for the better understanding of the evolution of ocrea. The morphological and developmental study of ocrea in genus Korthalsia included detailed study using Light and Scanning Electron Microscopy for seven samples of 28 species of Korthalsia, in order to provide understanding of ocrea morphological traits. -

Palmtraits 1.0, a Species-Level Functional Trait Database of Palms Worldwide
www.nature.com/scientificdata OPEN PalmTraits 1.0, a species-level Data Descriptor functional trait database of palms worldwide Received: 3 June 2019 W. Daniel Kissling 1, Henrik Balslev2, William J. Baker 3, John Dransfeld3, Bastian Göldel2, Accepted: 9 August 2019 Jun Ying Lim1, Renske E. Onstein4 & Jens-Christian Svenning2,5 Published: xx xx xxxx Plant traits are critical to plant form and function —including growth, survival and reproduction— and therefore shape fundamental aspects of population and ecosystem dynamics as well as ecosystem services. Here, we present a global species-level compilation of key functional traits for palms (Arecaceae), a plant family with keystone importance in tropical and subtropical ecosystems. We derived measurements of essential functional traits for all (>2500) palm species from key sources such as monographs, books, other scientifc publications, as well as herbarium collections. This includes traits related to growth form, stems, armature, leaves and fruits. Although many species are still lacking trait information, the standardized and global coverage of the data set will be important for supporting future studies in tropical ecology, rainforest evolution, paleoecology, biogeography, macroecology, macroevolution, global change biology and conservation. Potential uses are comparative eco- evolutionary studies, ecological research on community dynamics, plant-animal interactions and ecosystem functioning, studies on plant-based ecosystem services, as well as conservation science concerned with the loss and restoration of functional diversity in a changing world. Background & Summary Most ecosystems are composed of a large number of species with diferent characteristics. Tese characteristics (i.e. traits) refect morphological, reproductive, physiological, phenological, or behavioural measurements of spe- cies that are usually collected to study intraspecifc trait variation (i.e. -

In order to infer taxonomic relationships of these groups, morphological and anatomical data in members of the two tribes are compared with available studies in other tribes of the basal clades of the core arecoids, as defined by recent molecular phylogenies. Our results suggest an isolated position for Manicaria and highlight unexpected affinities between the tribe Leopoldinieae and representatives of the western Pacific Ocean tribe Pelagodoxeae.
