  • Epidemiology of the Invasion by Miconia Calvescens And
    J.-Y. Meyer 4 EPIDEMIOLOGY OF THE INVASION BY MICONIA CALVESCENS AND REASONS FOR A SPECTACULAR SUCCESS ÉPIDÉMIOLOGIE DE L’INVASION PAR MICONIA CALVESCENS ET RAISONS D’UN SUCCÈS SPECTACULAIRE JEAN-YVES MEYER1, 2 1 Délégation à la Recherche, B.P. 20981 Papeete, Tahiti, POLYNÉSIE FRANÇAISE. 2 Cooperative National Park Resource Studies Unit, Botany Department, University of Hawai’i at Manoa, Honolulu, HAWAI’I (USA). Miconia calvescens is a small tree native to rainforests of tropical America where it is uncommon. First described around 1850, it was introduced to European tropical greenhouses then distributed to tropical botanical gardens all over the world because of its horticultural success. M.c. was introduced as an ornamental plant in the Society Islands and the Hawaiian Islands and in 25-35 years became a dominant invasive plant in both archipelagoes. Small populations were recently discovered in the Marquesas Islands (Nuku Hiva and Fatu Iva) in 1997. M.c. is also naturalized in private gardens of New Caledonia and Grenada (West Indies), in tropical forests of Sri Lanka, and in the Queensland region in Australia. The survey of the epidemiology of invasion in Tahiti shows that M.c.’s extension was slow but continuous since its introduction in 1937. Hurricanes of 1982-83 played more a role of “revealer” rather than of “detonator” of the invasion. The lag phase observed between the introduction date and the observation of dense populations may be explained by the generation time of M.c.. Several hypothesis may explain the spectacular success of M.c.: (1) the characteristics of the invaded area; (2) the plant’s bio-ecological characteristics; (3) the “facilitation phenomenon“ and the “opportunities“.

  • Leaf Structural Characters of Leandra and Miconia
    Bol. Mus. Para. Emílio Goeldi. Cienc. Nat., Belém, v. 14, n. 3, p. 425-437, set.-dez. 2019 Leaf structural characters of Leandra and Miconia (Miconieae: Melastomataceae): taxonomic and ecological significance Caracteres estruturais foliares de Leandra e Miconia (Miconieae: Melastomataceae): importância taxonômica e ecológica Raísa Gonçales-SilvaI | Odair José Garcia de AlmeidaII | Luiz Antonio de SouzaI IUniversidade Estadual de Maringá. Maringá, Paraná, Brasil IIUniversidade Estadual Paulista. São Vicente, São Paulo, Brasil Abstract: Leaves of six species of Leandra and Miconia were investigated to find structural characters of interest for the classification of species and genera, as well as those that may be related to water stress. Specimens were collected in Guartelá State Park, Brazil, and described morphologically. Anatomical studies were performed on leaf samples embedded in historesin and sectioned through a rotating microtome. Scanning electron microscopy was done on material fixed in glutaraldehyde. Leandra leaves are lanceolate-ovate, while Miconia leaves have oblong-lanceolate and lanceolate blades. Both genera have a vascular system of the petiole composed of collateral, bicolateral, and anficrials bundles. The leaves are hypoestomatic and dorsiventral, varying in the number of strata of the parenchyma. The midrib consists of concentric collateral bundles (U-shaped, V-shaped or circular) or concentric bundles. The morphology of the indument, the structure of the mesophyll, and the vascularization of the midrib are characteristics of interest for the diagnosis of species. They are probably species that avoid drought and consist of plants capable of reducing or compensating for water loss. Keywords: Leaf blade anatomy. Indumentum. Leaf anatomy. Midrib vasculature. Petiole vasculature. Resumo: Folhas de seis espécies de Leandra e Miconia foram investigadas estruturalmente, com atenção aos caracteres de interesse para separação das espécies e dos gêneros, bem como àqueles que podem estar relacionados ao estresse hídrico.

This paper characterizes the leaf indumentum of Miconia albicans (Sw.) Triana, M. chamissois Naudin, M. fallax DC., M. ligustroides (DC.) Naudin, Microlepis oleaefolia (DC.) Triana and Rhynchanthera dichotoma DC., typical species from Brazilian cerrado. Samples collected from the median third of young and mature leaf blades were processed following the usual scanning electron microscopy techniques (SEM). We observed ten morphological types of trichomes and four of emergences. With five different types, four of which are reported for the first time, Rhynchanthera dichotoma is the species that presents the most diverse indumenta. A mixed type of trichome formed by a glandular and a branched non-glandular portion called “lateral-gland” was observed in M. ligustroides. Such non-glandular portion presents different degrees of development. A correlation is suggested between the stage of development of the non-glandular portion and the exposition to light of these “lateral gland” on young leaves. Key words: emergence, leaf, trichome, morphology. Resumo A grande diversidade de tricomas, variando desde estruturas unicelulares a tricomas muito complexos é uma característica marcante em Melastomataceae.

Integrated within a flower, labile floral characters produce different phenotypes that promote variable interactions with pollinators. Thus, investigation of floral evolution may help infer potential historic transitions in pollinator modes and ecological pressures that generated present diversity. This study aims to explore morphological evolution of flowers in Miconieae, a species-rich Neotropical tribe within family Melastomataceae. Despite a constrained floral plan, Melastomataceae manage to achieve a variety of floral traits appealing to diverse pollinator types, with majority of the species requiring specialized “buzz pollination” by bees. However, previous research in Miconieae documented several instances of convergent evolution of phenotypes associated with generalized pollination strategies. I explore morphological evolution of Miconieae in a phylogenetic context to understand how diversification relates to different phenotypes, and how common evolution of generalized pollination systems is within this tribe.
