Floristic and Ecological Characterization of Habitat Types on an Inselberg in Minas Gerais, Southeastern Brazil
Acta Botanica Brasilica - 31(2): 199-211. April-June 2017. doi: 10.1590/0102-33062016abb0409 Floristic and ecological characterization of habitat types on an inselberg in Minas Gerais, southeastern Brazil Luiza F. A. de Paula1*, Nara F. O. Mota2, Pedro L. Viana2 and João R. Stehmann3 Received: November 21, 2016 Accepted: March 2, 2017 . ABSTRACT Inselbergs are granitic or gneissic rock outcrops, distributed mainly in tropical and subtropical regions. Th ey are considered terrestrial islands because of their strong spatial and ecological isolation, thus harboring a set of distinct plant communities that diff er from the surrounding matrix. In Brazil, inselbergs scattered in the Atlantic Forest contain unusually high levels of plant species richness and endemism. Th is study aimed to inventory species of vascular plants and to describe the main habitat types found on an inselberg located in the state of Minas Gerais, in southeastern Brazil. A total of 89 species of vascular plants were recorded (belonging to 37 families), of which six were new to science. Th e richest family was Bromeliaceae (10 spp.), followed by Cyperaceae (seven spp.), Orchidaceae and Poaceae (six spp. each). Life forms were distributed in diff erent proportions between habitats, which suggested distinct microenvironments on the inselberg. In general, habitats under similar environmental stress shared common species and life-form proportions. We argue that fl oristic inventories are still necessary for the development of conservation strategies and management of the unique vegetation on inselbergs in Brazil. Keywords: endemism, granitic and gneissic rock outcrops, life forms, terrestrial islands, vascular plants occurring on rock outcrops within the Atlantic Forest Introduction domain, 416 are endemic to these formations (Stehmann et al. -

Phylogeny and Classification of the Melastomataceae and Memecylaceae
Nord. J. Bot. - Section of tropical taxonomy Phylogeny and classification of the Melastomataceae and Memecy laceae Susanne S. Renner Renner, S. S. 1993. 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. -

Vestured Pits in Wood of Onagraceae: Correlations with Ecology, Habit, and Phylogeny1
VESTURED PITS IN WOOD OF Sherwin Carlquist2 and Peter H. Raven3 ONAGRACEAE: CORRELATIONS WITH ECOLOGY, HABIT, AND PHYLOGENY1 ABSTRACT All Onagraceae for which data are available have vestured pits on vessel-to-vessel pit pairs. Vestures may also be present in some species on the vessel side of vessel-to-ray pit pairs. Herbaceous Onagraceae do not have fewer vestures, although woods with lower density (Circaea L. and Oenothera L.) have fewer vestures. Some Onagraceae from drier areas tend to have smaller vessel pits, and on that account may have fewer vestures (Epilobium L. and Megacorax S. Gonz´alez & W. L. Wagner). Pit apertures as seen on the lumen side of vessel walls are elliptical, occasionally oval, throughout the family. Vestures are predominantly attached to pit aperture margins. As seen from the outer surfaces of vessels, vestures may extend across the pit cavities. Vestures are usually absent or smaller on the distal portions of pit borders (except for Ludwigia L., which grows consistently in wet areas). Distinctive vesture patterns were observed in the several species of Lopezia Cav. and in Xylonagra Donn. Sm. & Rose. Vestures spread onto the lumen-facing vessel walls of Ludwigia octovalvis (Jacq.) P. H. Raven. Although the genera are presented here in the sequence of a recent molecular phylogeny of Onagraceae, ecology and growth forms are more important than evolutionary relationships with respect to abundance, degree of grouping, and morphology of vestured pits. Designation of vesture types is not warranted based on the distribution of named types in Onagraceae and descriptive adjectives seem more useful, although more data on vesturing in the family are needed before patterns of diversity and their extent can be fully ascertained. -

UNIVERSIDAD DE LA Ingenierías & Amazonia 7 (1), 2014 AMAZONIA APORTES A LA ECOLOGÍA DE Alloneuron ulei Pilg. (Melastomataceae) EN EL SENDERO ECOLÓGICO COMUNITARIO EL MANANTIAL (FLORENCIA-CAQUETÁ) Kimberly Hasbledy Tobón González, Robinson Pinilla Barrero & Edwin Trujillo Trujillo Artículo recibido el 08 de enero de 2014, aprobado para publicación el 06 de Junio de 2014. Resumen Melastomataceae (Myrtales) es la séptima familia más diversa del planeta, con cerca de 4400 especies presentes en todos los países intertropicales y subtropicales. El género Alloneuron, cuenta solo con 4 especies, distribuidas a lo largo del piedemonte oriental de los Andes y de la Amazonia noroccidental. En Colombia es registrada únicamente la especie A. ulei Pilg, la cual fue reportada en el departamento de Caquetá entre 500-1000 msnm y en el departamento de Putumayo a 700 msnm. Alloneuron ulei es una planta de hábitat muy restringido asociado a cascadas, quebradas y rocas en zonas sombreadas. Para esta especie solamente son descritos aspectos taxonómicos. En el año 2009, se redescubrió una población en el sendero ecológico Moniya Amena (Florencia). La población en la reserva comunitaria El Manantial es compuesta por 2864 individuos, donde el 21,56% se encuentra en la zona baja del sendero y el 78,35% en la zona alta; siendo el 46,88% adultos y el 53,12% juveniles. En relación la biología floral, la antesis ocurre a los 25 días y su completo desarrollo se da en 27 días; cuando no hay fecundación la flor dura 3 días más. Subsecuente a la fecundación, los pétalos, el gineceo y androceo se caen e inicia el engrosamiento del cáliz para formar el fruto. -
Bayesian Analysis of Combined Chloroplast Loci, Using Multiple Calibrations, Supports the Recent Arrival of Melastomataceae in Africa and Madagascar1
American Journal of Botany 91(9): 1427±1435. 2004. BAYESIAN ANALYSIS OF COMBINED CHLOROPLAST LOCI, USING MULTIPLE CALIBRATIONS, SUPPORTS THE RECENT ARRIVAL OF MELASTOMATACEAE IN AFRICA AND MADAGASCAR1 SUSANNE S. RENNER Systematische Botanik, Ludwig-Maximilians University, D-80638 Munich, Germany A new biogeographic scenario for Melastomataceae (Morley and Dick, American Journal of Botany 90(11) pp. 1638±1645, 2003) accepts an ndhF-based phylogeny for the family by Renner et al. (American Journal of Botany 88(7): 1290±1300, 2001), but rejects those authors' divergence time estimates. Morley and Dick concluded that Gondwanan vicariance, rather than the more recent long dispersal proposed by Renner et al. explains the presence of the family in Africa and Madagascar. To assess the strength of this conclusion, a Bayesian analysis was conducted on three times the amount of sequence data used before (ndhF, rbcL, rpl16; 3100 base pairs [bp], excluding all gaps). The Bayesian approach to divergence time estimation does not rely on a strict molecular clock and employs multiple simultaneous minimal or maximal bounds on node ages. Reliance on northern mid-latitude fossils of Melastomataceae for calibrations was avoided or reduced by using alternative fossil and tectonic calibrations, including all those suggested by Morley and Dick. Results reaf®rm the relatively recent spread of melastome lineages among the southern continents and refute the breakup of Gondwana as a plausible explanation for the presence of Dissochaeteae/Sonerileae in Madagascar and Africa and the presence of Melastomeae in Africa and Southeast Asia. Melastomeae appear to have reached Africa around 17±15 million years (my) ago, while Dissochaeteae and Sonerileae apparently reached Madagascar at 17±15 and 20±18 my ago. -

PhytoKeys 136: 1–21. https://doi.org/10.3897/ phytokeys.136.38558 Abstract The systematics of Tryssophyton, herbs endemic to the Pakaraima Mountains of western Guyana, is re- viewed and Tryssophyton quadrifolius K.Wurdack & Michelang., sp. nov. from the summit of Kamakusa Mountain is described as the second species in the genus. The new species is distinguished from its closest relative, Tryssophyton merumense, by striking vegetative differences, including number of leaves per stem and leaf architecture. A phylogenetic analysis of sequence data from three plastid loci and Melastomata- ceae-wide taxon sampling is presented. The two species of Tryssophyton are recovered as monophyletic and associated with mostly Old World tribe Sonerileae. Fruit, seed and leaf morphology are described for the first time, biogeography is discussed and both species are illustrated. -
9 Costion Plant Endemism 133-166 PROOFS
Micronesica 41(1): 131–164, 2009 Plant Endemism, Rarity, and Threat in Palau, Micronesia: A Geographical Checklist and Preliminary Red List Assessment 1 CRAIG M. COSTION Department of Ecology and Evolutionary Biology, School of Earth and Environmental Sciences, University of Adelaide, Adelaide SA 5001 [email protected] ANN HILLMANN KITALONG The Environment, Inc., P.O. Box 1696, Koror, Palau 96940 TARITA HOLM Palau Conservation Society/PALARIS, P.O. Box 1811, Koror, Palau, 96940 Abstract—An official checklist of the endemic plant species of Palau has been long awaited, and is presented here for the first time. For each species a substrate limitation, growth form, and relative abundance is listed. In addition an IUCN red list assessment was conducted using all available data. For over half of the endemic species there is insufficient data to provide a red listing status however an expected minimum number of threatened plants out of the total is inferred. Approximately 15% of Palau’s endemic plants are believed to be only known from the type collection and many more only known from a few collections. These taxa however may now be prioritized and targeted for future inventory and research. The taxonomic robustness of several of these taxa is questionable and it is expected that more endemic species will be lost to synonymy in the future. Previous estimations have significantly over-estimated the rate of plant endemism in Palau (e.g., 194). Here, 130 plants are recognized for Palau, making its level of plant endem- ism comparable to some of its neighboring Micronesian islands to the east, notably Guam and Pohnpei. -

Pollen tube growth rates (PTGRs) of angiosperms are exceptionally rapid, a pattern 25 attributed to more effective haploid selection under stronger pollen competition. Paradoxically, 26 whole genome duplication (WGD) has been common in angiosperms but rare in gymnosperms.
