HEARN Department of Ecology and Evolutionary Biology, University of Arizona, Tucson, Arizona 85721, USA ([email protected]) ABSTRACT To understand evolutionary patterns and processes that account for anatomical diversity in relation to ecology and life form diversity, anatomy of storage roots and stems of the genus Adenia (Passifloraceae) were analyzed using an explicit phylogenetic context. Over 65,000 measurements are reported for 47 quantitative and qualitative traits from 58 species in the genus. Vestiges of lianous ancestry were apparent throughout the group, as treelets and lianous taxa alike share relatively short, often wide, vessel elements with simple, transverse perforation plates, and alternate lateral wall pitting; fibriform vessel elements, tracheids associated with vessels, and libriform fibers as additional tracheary elements; and well-developed axial parenchyma. Multiple cambial variants were observed, including anomalous parenchyma proliferation, anomalous vascular strands, successive cambia, and a novel type of intraxylary phloem.

  • The Island Rule and Its Application to Multiple Plant Traits
    The island rule and its application to multiple plant traits Annemieke Lona Hedi Hendriks A thesis submitted to the Victoria University of Wellington in partial fulfilment of the requirements for the degree of Master of Science in Ecology and Biodiversity Victoria University of Wellington, New Zealand 2019 ii “The larger the island of knowledge, the longer the shoreline of wonder” Ralph W. Sockman. iii iv General Abstract Aim The Island Rule refers to a continuum of body size changes where large mainland species evolve to become smaller and small species evolve to become larger on islands. Previous work focuses almost solely on animals, with virtually no previous tests of its predictions on plants. I tested for (1) reduced floral size diversity on islands, a logical corollary of the island rule and (2) evidence of the Island Rule in plant stature, leaf size and petiole length. Location Small islands surrounding New Zealand; Antipodes, Auckland, Bounty, Campbell, Chatham, Kermadec, Lord Howe, Macquarie, Norfolk, Snares, Stewart and the Three Kings. Methods I compared the morphology of 65 island endemics and their closest ‘mainland’ relative. Species pairs were identified. Differences between archipelagos located at various latitudes were also assessed. Results Floral sizes were reduced on islands relative to the ‘mainland’, consistent with predictions of the Island Rule. Plant stature, leaf size and petiole length conformed to the Island Rule, with smaller plants increasing in size, and larger plants decreasing in size. Main conclusions Results indicate that the conceptual umbrella of the Island Rule can be expanded to plants, accelerating understanding of how plant traits evolve on isolated islands.

Algumas espécies de Passiflora já foram analisadas citogeneticamente, mas pouco é sabido sobre espécies que ocorrem na Amazônia. Neste contexto, o objetivo deste trabalho foi compilar dados citogenéticos do gênero Passiflora bem como determinar a composição cromossômica da espécie Passiflora coccinea proveniente do fragmento florestal da Universidade Federal do Amazonas. Para isto, os meristemas radiculares foram pré-tratados com solução antimitótica 8- hidroxiquiloneína e fixados com Carnoy. As preparações cromossômicas foram realizadas pela técnica de dissociação celular e submetidas à coloração convencional com Giemsa. A morfologia cromossômica foi determinada com base na razão entre os braços. No presente trabalho, o tempo de pré-tratamento mais adequado foi três horas, apresentando um maior número de células em metáfases mitóticas e melhor morfologia cromossômica em Passiflora coccinea. O número diploide foi igual a 72, sendo 26 cromossomos metacêntricos/submetacêntricos e 46 acrocêntricos (26 m/sm + 46a) e número fundamental de braços igual a 98. Assim, os resultados obtidos neste estudo revelaram uma composição cariotípica inédita para a espécie Passiflora coccinea, reforçando a importância no aumento de análises cromossômicas no gênero Passiflora, essenciais para a compreensão da organização do genoma deste grupo de plantas.

    96 East and Central African Journal of Pharmaceutical Sciences Vol. 18 (2015) 96-99 An in vitro Study on the Oxytocic Action of Adenia Globosa Engl. K. A. SINEI* AND J. W. MWANGI Department of Pharmacology and Pharmacognosy, School of Pharmacy, University Of Nairobi, P.O. Box 19676 – 00202; Nairobi, Kenya. Adenia spp. (Passifloraceae) grows widely in many parts of Eastern and Southern Africa. Though some species of the plant are known to be generally toxic, a few of them are used in traditional medical practices. Among the many uses is the claim that when given to goats and cows which have difficulty in giving birth, it hastens the process of giving birth. We found this of interest and set out to investigate it further. We determined the effect of the water extract of Adenia globosa on the isolated preparation of the rat uterus and how this action interacts with ergometrine and prostaglandin F2α, two well-established uterine stimulants. The crude extract and the other drugs were tested on isolated rat uterus set up in an organ bath under the usual laboratory conditions. The results obtained showed that the plant extract caused a dose-dependent contraction of the rat uterus. The contractile effect was potentiated by small doses of ergometrine and prostaglandin F2α. It was therefore postulated that since prostaglandin F-2α also exists as an endogenous hormone which is released at the time of labour, the observed potentiation probably occurs in vivo when the plant preparation is given to domestic animals to ease and speed up the process of giving birth as claimed in the traditional use of this plant.

Lohmann Abstract—Phylogenetic relationships of Passiflora subgenus Decaloba were examined using 148 taxa and four molecular markers: nuclear nrITS, ncpGS, cp trnL-F, and ndhF. Relationships of subgenus Decaloba to the other four Passiflora subgenera (Astrophea, Deidamioides, Tetrapathea,andPassiflora) are investigated, as are relationships among the eight supersections within subgenus Decaloba. Results indicate that subgenus Deidamioides is not monophyletic. Subgenus Astrophea + subgenus Deidamioides (section Tryphostemmatoides) together form the most basally branching lineage in the genus, followed by a clade comprised of subgenus Passiflora + subgenus Deidamioides (sections Tetrastylis, Polyanthea, and Deidamioides). Passiflora obovata (subgenus Deidamioides section Mayapathanthus) is resolved as part of subgenus Decaloba.

  • Planting a Dry Rock Garden in Miam1
    Succulents in Miam i-D ade: Planting a D ry Rock Garden John McLaughlin1 Introduction The aim of this publication is twofold: to promote the use of succulent and semi-succulent plants in Miami-Dade landscapes, and the construction of a modified rock garden (dry rock garden) as a means of achieving this goal. Plants that have evolved tactics for surviving in areas of low rainfall are collectively known as xerophytes. Succulents are probably the best known of such plants, all of them having in common tissues adapted to storing/conserving water (swollen stems, thickened roots, or fleshy and waxy/hairy leaves). Many succulent plants have evolved metabolic pathways that serve to reduce water loss. Whereas most plants release carbon dioxide (CO2) at night (produced as an end product of respiration), many succulents chemically ‘fix’ CO2 in the form of malic acid. During daylight this fixed CO2 is used to form carbohydrates through photosynthesis. This reduces the need for external (free) CO2, enabling the plant to close specialized pores (stomata) that control gas exchange. With the stomata closed water loss due to transpiration is greatly reduced. Crassulacean acid metabolism (CAM), as this metabolic sequence is known, is not as productive as normal plant metabolism and is one reason many succulents are slow growing. Apart from cacti there are thirty to forty other plant families that contain succulents, with those of most horticultural interest being found in the Agavaceae, Asphodelaceae (= Aloacaeae), Apocynaceae (now including asclepids), Aizoaceae, Crassulaceae, Euphorbiaceae and scattered in other families such as the Passifloraceae, Pedaliaceae, Bromeliaceae and Liliaceae.
