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. -
1 Ornamental Palms
1 Ornamental Palms: Biology and Horticulture T.K. Broschat and M.L. Elliott Fort Lauderdale Research and Education Center University of Florida, Davie, FL 33314, USA D.R. Hodel University of California Cooperative Extension Alhambra, CA 91801, USA ABSTRACT Ornamental palms are important components of tropical, subtropical, and even warm temperate climate landscapes. In colder climates, they are important interiorscape plants and are often a focal point in malls, businesses, and other public areas. As arborescent monocots, palms have a unique morphology and this greatly influences their cultural requirements. Ornamental palms are over- whelmingly seed propagated, with seeds of most species germinating slowly and being intolerant of prolonged storage or cold temperatures. They generally do not have dormancy requirements, but do require high temperatures (30–35°C) for optimum germination. Palms are usually grown in containers prior to trans- planting into a field nursery or landscape. Because of their adventitious root system, large field-grown specimen palms can easily be transplanted. In the landscape, palm health and quality are greatly affected by nutritional deficien- cies, which can reduce their aesthetic value, growth rate, or even cause death. Palm life canCOPYRIGHTED also be shortened by a number of MATERIAL diseases or insect pests, some of which are lethal, have no controls, or have wide host ranges. With the increasing use of palms in the landscape, pathogens and insect pests have moved with the Horticultural Reviews, Volume 42, First Edition. Edited by Jules Janick. 2014 Wiley-Blackwell.

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. -

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. -

Indigenous Palm Flora – 4
INDIGENOUS PALM FLORA – 4 4.1. INTRODUCTION Vegetation is the most valuable gift of nature which provides us all kinds of essential requirements for our survival, including food, fodder, medicine, fuel, timber, resins, oils etc. Natural resources survey like floristic study plays an important role in the economic improvement of developing country (Ganorkar and Kshirsagar 2013). Beside this, floristic study of a particular region is also reflects the picture of natural assemblage of plants, which include total information on numbers of family, genus and species, dominant genera, dominant families and major life-forms occupying a particular habitat (Sasidharan 2002). Likewise, knowledge of the floristic composition of any place is the necessary pre-requisite for the study of various ecosystems. Palms diversity in West Bengal is one of the most important requisites, not only from the taxonomic view point but to increase of our knowledge also for the benefit of science and the society. Various natural reservoirs like in situ conservatories of West Bengal are quite rich in different species of palms and rattans. The plains, Gangetic delta, western plateau are the houses of few species of rattans and palms but the forested areas of northern plains, sub-Himalayan terai, duars and hills of Darjeeling-Kalimpong are very much rich in diversified palm and rattans species with quite a good population sizes. The earliest record of Indian palms appreciated in Hortus Malabaricus (Van Rheede 1678) where only 9 palms species were described with figures. About 71 species of palms and rattans were recorded from undivided India by Sir J. D. Hooker in his book Flora of British India (1892 -1893). -

Tropical Plant Research 7(2): 374–378] INTRODUCTION The genus Arenga Labill and Livistona R. Br., are represented by one and two species in Bangladesh respectively (Siddiqui et al. 2007, Rahman 2018). In Bangladesh, these genera were known to contain the following three species: Arenga pinnata (Wurmb) Merr., Livistona chinensis (Jacq.) R.Br. ex Mart. and Livistona speciosa Kurz. (Siddiqui et al. 2007, Rahman 2018). Sangu-Matamuhuri Reserve Forest is one of the last strongholds of biodiversity in Bangladesh (Creative Conservation Alliance 2016). Sangu Reserve Forest (SRF hereafter) is located in the south of Boro Modok in Thanchi Upazila of Bandarban District, Bangladesh (Fig. 1). The actual floral diversity of SRF is still unknown. We conducted a field exploration at this remote forest during February 2019. SRF is a part of the Indo-Burma Biodiversity hot spot (Myers et al. 2000).

House of Adi Tribe of Arunachal Pradesh: Construction Materials and the Use of Space
International Journal of Innovative Research and Advanced Studies (IJIRAS) ISSN: 2394-4404 Volume 2 Issue 12, December 2015 House Of Adi Tribe Of Arunachal Pradesh: Construction Materials And The Use Of Space Nung Boko D. Narsimhan Centre for Floristic Research, Department of Botany Madras Christian College (Autonomous), Tambaram, Chennai Abstract: Adi is one of the major tribes of Arunachal Pradesh, in North East India. A typical Adi house is raised on stilts. Every part of the Adi house has some specific name and each part has unique functional significance. Different species of bamboo, palm, cane and timber formed the construction materials for a traditional Adi house. Traditionally it is believed that the construction materials collected during a particular period last long and are free from the attack of termites and other insects. Keywords: Adi tribe, traditional house, bamboo, cane, palm I. INTRODUCTION the moon. This paper deals about the construction materials and use of space in a traditional Adi house. Adi people reside mostly in the foothills of the Eastern Himalaya and they are one of the major tribes of Arunachal Pradesh (Mandal et al. 2002). Out of the total 18 districts of II. METHODOLOGY the state Adi tribe live in six districts, namely East Siang, West Siang, Upper Siang, Lower Dibang Valley, Lohit and Upper Banggo is the basic traditional administrative unit for Adi Subansiri (Modi 2007). Adi is divided into 14 sub-tribes such tribe. Each banggo consists a cluster of villages of varying as Ashing, Bori, Bokar, Karko, Komkar, Minyong, Millang, numbers. This study was conducted in Yagrung village of Pasi, Padam, Panggi, Pailibo, Ramo, Shimong and Tangam Bosing Banggo (Figure1).
