Phylogeny and classification of the Melastomataceae and Memecy- laceae. - Nord. J. Bot. 13: 519-540. Copenhagen. ISSN 0107-055X. A systematic analysis of the Melastomataceae, a pantropical family of about 4200- 4500 species in c. 166 genera, and their traditional allies, the Memecylaceae, with c. 430 species in six genera, suggests a phylogeny in which there are two major lineages in the Melastomataceae and a clearly distinct Memecylaceae. Melastomataceae have close affinities with Crypteroniaceae and Lythraceae, while Memecylaceae seem closer to Myrtaceae, all of which were considered as possible outgroups, but sister group relationships in this plexus could not be resolved. Based on an analysis of all morph- ological and anatomical characters useful for higher level grouping in the Melastoma- taceae and Memecylaceae a cladistic analysis of the evolutionary relationships of the tribes of the Melastomataceae was performed, employing part of the ingroup as outgroup. Using 7 of the 21 characters scored for all genera, the maximum parsimony program PAUP in an exhaustive search found four 8-step trees with a consistency index of 0.86. Because of the limited number of characters used and the uncertain monophyly of some of the tribes, however, all presented phylogenetic hypotheses are weak. A synapomorphy of the Memecylaceae is the presence of a dorsal terpenoid-producing connective gland, a synapomorphy of the Melastomataceae is the perfectly acrodro- mous leaf venation. Within the Melastomataceae, a basal monophyletic group consists of the Kibessioideae (Prernandra) characterized by fiber tracheids, radially and axially included phloem, and median-parietal placentation (placentas along the mid-veins of the locule walls).

(MELASTOMATACEAE) ON MT MAKILING, PHILIPPINES J. Peter Quakenbush1 ABSTRACT An investigation into the reproductive biology of Medinilla multiflora Merr. (Melastomataceae) from Mt Makiling, Luzon, is presented. This includes a morphological and distributional exami- nation of the population on the mountain, the documentation of reproductive phenological patterns, a study of the mating system and observations of biotic interactions. Measurements were made of trait variability, reproductive phenology was characterised from field and herbarium observations, stigmatic receptivity was tested by counting pollen germination, insect exclusion and hand-pollination experiments helped determine the mating system and field observations recorded the identity and behaviour of floral visitors. Significant reproductive morphological differences were found between described populations. This identified a need for the recognition of this diversity and further delimitation of the Medinilla multiflora species complex. Although Medinilla multiflora produced flowers and fruit year-round, the population also exhibited cycles of increased reproduction most likely initiated by seasonal low temperatures.

    Insert as an Additional Taxa For Ardisia japonica: Ardisia crenata J. Sims Coralberry (Ardisia crenulata) C This is species is also known as Spiceberry; Coralberry is a larger version of A. japonica forming a rounded woody evergreen shrub 3N to 5N(6N) tall; the 4O to 6O(8O) long elliptic-lanceolate to oblanceolate lustrous dark green leaves have crenate-undulate margins; the foliage tends to be bunched toward the ends of the stems; the specific epithet refers to these crenate leaves. C Plants have small ¼O long white to pink inverted urn-shaped flowers in cymes in spring to summer; however, the species’ primary asset is the massed clusters of bright shiny red fruits; they are extremely showy, contrasting handsomely with the dark green foliage, ala a holly mimic. C Originating from Japan and Southeast Asia, this species has limited cold tolerance, but good heat tolerance’ it is effective in USDA zones 8(7) to 10 landscapes; plants are prolific seed producers and have naturalized extensively in eastern portions of the Gulf Coast; they are often found along woodland edges, but can tolerate full sun where adequate moisture is available; growth is best in well drained, moist, fertile, acidic to neutral soils; unfortunately, A. crenata can become weedy in favorable environments. C Ardisia crispa (C. Thunberg) A.P. de Candolle, Coral Ardisia, is a similar, but less cold hardy groundcover sometimes encountered along the Gulf Coast in South Texas or as an interiorscape plant.

  • Forest Structures, Composition, and Distribution on a Pacific Island, with Reference to Ecological Release and Speciation!
    Pacific Science (1991), vol. 45, no. 1: 28-49 © 1991 by University of Hawaii Press. All rights reserved Forest Structures, Composition, and Distribution on a Pacific Island, with Reference to Ecological Release and Speciation! YOSHIKAZU SHIMIZU2 AND HIDEO TABATA 3 ABSTRACT: Native forest and scrub of Chichijima, the largest island in the Bonins, were classified into five types based on structural features: Elaeocarpus­ Ardisia mesic forest, 13-16 m high, dominated by Elaeocarpus photiniaefolius and Ardisia sieboldii; Pinus-Schima mesic forest, 12-16 m high, consisting of Schima mertensiana and an introduced pine , Pinus lutchuensis; Rhaphiolepis­ Livistonia dry forest, 2-6 m high, mainly occupied by Rhaphiolepis indica v. integerrima; Distylium-Schima dry forest, 3-8 m high, dominated by Distylium lepidotum and Schima mertensiana; and Distylium-Pouteria dry scrub, 0.3­ 1.5 m high, mainly composed of Distylium lepidotum. A vegetation map based on this classification was developed. Species composition and structural features of each type were analyzed in terms of habitat condition and mechanisms of regeneration. A group of species such as Pouteria obovata, Syzgygium buxifo­ lium, Hibiscus glaber, Rhaphiolepis indica v. integerrima, and Pandanus boninen­ sis, all with different growth forms from large trees to stunted shrubs, was subdominant in all vegetation types. Schima mertensiana , an endemic pioneer tree, occurred in both secondary forests and climax forests as a dominant canopy species and may be an indication of "ecological release," a characteristic of oceanic islands with poor floras and little competitive pressure. Some taxonomic groups (Callicarpa, Symplocos, Pittosporum, etc.) have speciated in the under­ story of Distylium-Schima dry forest and Distylium-Pouteria dry scrub.

  • Growing Your Medinilla Speciosa Plant
    Growing your Medinilla speciosa plant Medinilla speciosa is a relatively recent introduction to Australia. It is a small to medium shrub, growing to around 2 metres. The large, almost succulent leaves are heavily veined and make an attractive contrast in the garden. Of course the outstanding feature of this plant are the flowers. They are formed in large pendulous racemes. The new flowers open a light pink, followed by hot pink berries which ripen to purple. There is always varying colours of flower and fruit on the shrub at any given time, making it a great specimen for any tropical or sub- tropical garden or even for pot culture. When your plant arrives, it is important to get it potted up as soon as possible. I would use a standard 150-200 mm pot and a well drained soil mix, I use Searle’s brand. Add a teaspoon of Osmocote and water in well. Keep your plant in bright filtered light with maybe some early morning sun for a couple of weeks until it starts to re-establish, then slowly move it to more morning sun with protection from hot afternoon sun. Pot on as needed, the roots are quite fast growing. Occasional trimming after the bulk of the flowering has finished will form a more compact plant. Water well during dry periods and feed once or twice a year with a complete fertiliser or dynamic lifter. The only major pests of this plant are chewing insects such as Grasshoppers and Caterpillars, these can simply be crushed or sprayed with the insecticide Carbaryl.
