The family is monophyletic (Feng 2005, Tukuoka 2008, Wahlert & Ballard 2010 in press), even though phylogenetic relationships within Violaceae are still unclear (Feng 2005, Tukuoka 2008). The family embrace a great diversity of vegetative and floral morphologies. Members are herbs, lianas or trees, with flowers ranging from strongly spurred to unspurred. -
The Genus Brassavola, (L.) R.Br
The Genus Brassavola, (L.) R.Br. in W.T.Aiton, Hortus Kew. 5: 216 (1813) Type: Brassavola [B.] cucullata [bra-SAH-vo-la kyoo-kyoo-LAH-ta] There are 28 species (OrchidWiz [update Dec 2017]) that are epiphytes and sometimes lithophytes at elevations of from sea level to 3300 ft (1000 m) from Mexico, southern Caribbean islands to northern Argentina in moist or wet montane forests, mangroves, rocky crevices and cliff faces. They are most fragrant at night and many with a citrus smell. The genus is characterized by very small pencil-like pseudobulbs, often forming large clumps; a single, fleshy, apical, sub-terete leaf and the inflorescence produced form the apex of the pseudobulb. The inflorescence carries from a single to a few large flowers. The floral characteristics are elongate narrow similar sepals and petals, the base of the lip usually tightly rolled around at least a portion of the column which carries 12, sometimes eight unequal pollina with prominent opaque caudicles. The flowers usually occur, as a rule, in spring, summer and fall. The flowers are generally yellow to greenish white with a mostly white lip. It is not unusual for dark spots, usually purple, to be in the region where the sepals, petals, and lip join the stem (claw). This spotting is a dominant generic trait in Brassavola nodose. They are easily cultivated under intermediate conditions. Although this is a relatively small genus (28 species), the species show an unusually close relationship with one another in their floral patterns, coloration, and column structure making identification difficult, key to know where the plants were collected. -

ARTICLE Floristic and Characterization of Grassland Vegetation at a Granitic Hill in Southern Brazil Robberson Bernal Setubal1* and Ilsi Iob Boldrini2
Revista Brasileira de Biociências Brazilian Journal of Biosciences http://www.ufrgs.br/seerbio/ojs ISSN 1980-4849 (on-line) / 1679-2343 (print) ARTICLE Floristic and characterization of grassland vegetation at a granitic hill in Southern Brazil Robberson Bernal Setubal1* and Ilsi Iob Boldrini2 Received: March 31 2009 Received after revision: November 19 2009 Accepted: November 20 2009 Available online at http://www.ufrgs.br/seerbio/ojs/index.php/rbb/article/view/1209 ABSTRACT: (Floristic and characterization of grasslands vegetation of a granite hill in Southern Brazil). A floristic and vegeta- tion study was carried out in the grassland formations at Morro São Pedro, Porto Alegre municipality, Rio Grande do Sul State, a granitic elevation area, so far poorly surveyed, that cradles important natural vegetation remnants of the region. After the study, which lasted from April 2005 to March 2009, we found 497 angiosperm species, distributed in four main grassland formation types: dry grassland, rocky grassland, humid grassland and wetlands. Among the species list three species are noteworthy: Alstroemeria albescens, a new species for the science, Lepuropethalon spathulatum, a new record for Southern Brazil, and Thrasyopsis juergensii, a new record for the Pampa biome. Based on our results and on support from other papers we concluded that ca. 65% of the grassland species present in the granitic hills of the region belong to seven main botanical families (Astera- ceae, Poaceae, Fabaceae, Cyperaceae, Rubiaceae, Verbenaceae and Apiaceae). The species belonging to these families are also determining in the vegetation phytophysiognomical and structural composition, so that cespitous grasses predominate in the landscape, shaping a continuous gramineous layer. -
CATALOGUE of the GRASSES of CUBA by A. S. Hitchcock
CATALOGUE OF THE GRASSES OF CUBA By A. S. Hitchcock. INTRODUCTION. The following list of Cuban grasses is based primarily upon the collections at the Estaci6n Central Agron6mica de Cuba, situated at Santiago de las Vegas, a suburb of Habana. The herbarium includes the collections made by the members of the staff, particularly Mr. C. F. Baker, formerly head of the department of botany, and also the Sauvalle Herbarium deposited by the Habana Academy of Sciences, These specimens were examined by the writer during a short stay upon the island in the spring of 1906, and were later kindly loaned by the station authorities for a more critical study at Washington. The Sauvalle Herbarium contains a fairly complete set of the grasses col- lected by Charles Wright, the most important collection thus far obtained from Cuba. In addition to the collections at the Cuba Experiment Station, the National Herbarium furnished important material for study, including collections made by A. H. Curtiss, W. Palmer and J. H. Riley, A. Taylor (from the Isle of Pines), S. M. Tracy, Brother Leon (De la Salle College, Habana), and the writer. The earlier collections of Wright were sent to Grisebach for study. These were reported upon by Grisebach in his work entitled "Cata- logus Plant arum Cubensium," published in 1866, though preliminary reports appeared earlier in the two parts of Plantae Wrightianae. * During the spring of 1907 I had the opportunity of examining the grasses in the herbarium of Grisebach in Gottingen.6 In the present article I have, with few exceptions, accounted for the grasses listed by Grisebach in his catalogue of Cuban plants, and have appended a list of these with references to the pages in the body of this article upon which the species are considered. -
Quite a Few Reasons for Calling Carnivores 'The Most Wonderful
Annals of Botany 109: 47–64, 2012 doi:10.1093/aob/mcr249, available online at www.aob.oxfordjournals.org REVIEW Quite a few reasons for calling carnivores ‘the most wonderful plants in the world’ Elz˙bieta Kro´l1,*,†, Bartosz J.

The morphological and physiological adaptations to carnivorous existence is most complex in plants, thanks to which carnivorous plants have been cited by Darwin as ‘the most wonderful plants in the world’. When considering the range of these adaptations, one realizes that the carnivory is a result of a multitude of different features. † Scope This review discusses a selection of relevant articles, culled from a wide array of research topics on plant carnivory, and focuses in particular on physiological processes associated with active trapping and digestion of http://aob.oxfordjournals.org/ prey. Carnivory offers the plants special advantages in habitats where nutrient supply is scarce. Counterbalancing costs are the investments in synthesis and the maintenance of trapping organs and hydrolysing enzymes. -
Phylogenetic Placement of the Enigmatic Orchid Genera Thaia and Tangtsinia: Evidence from Molecular and Morphological Characters

China 3 Xishuangbanna Tropical Botanical Garden, Chinese Academy of Sciences, Menglun Township, Mengla County, Yunnan province 666303, P.R. China Author for correspondence: Xiao-Hua Jin, [email protected] Abstract The phylogenetic position of two enigmatic Asian orchid genera, Thaia and Tangtsinia, were inferred from molecular data and morphological evidence. An analysis of combined plastid data (rbcL + matK + psaB) using Bayesian and parsimony methods revealed that Thaia is a sister group to the higher epidendroids, and tribe Neottieae is polyphyletic unless Thaia is removed. Morphological evidence, such as plicate leaves and corms, the structure of the gynostemium and the micromorphol- ogy of pollinia, also indicates that Thaia should be excluded from Neottieae. Thaieae, a new tribe, is therefore tentatively established. Using Bayesian and parsimony methods, analyses of combined plastid and nuclear datasets (rbcL, matK, psaB, trnL-F, ITS, Xdh) confirmed that the monotypic genus Tangtsinia was nested within and is synonymous with the genus Cepha- lanthera, in which an apical stigma has evolved independently at least twice. -
Arundinelleae; Panicoideae; Poaceae)
Bothalia 19, 1:45-52(1989) Kranz distinctive cells in the culm of ArundineUa (Arundinelleae; Panicoideae; Poaceae) EVANGELINA SANCHEZ*, MIRTA O. ARRIAGA* and ROGER P. ELLIS** Keywords: anatomy, Arundinella, C4, culm, distinctive cells, double bundle sheath, NADP-me ABSTRACT The transectional anatomy of photosynthetic flowering culms of Arundinella berteroniana (Schult.) Hitchc. & Chase and A. hispida (Willd.) Kuntze from South America and A. nepalensis Trin. from Africa is described and illustrated. The vascular bundles are arranged in three distinct rings, the outermost being external to a continuous sclerenchymatous band. Each of these peripheral bundles is surrounded by two bundle sheaths, a complete mestome sheath and an incomplete, outer, parenchymatous Kranz sheath, the cells of which contain large, specialized chloroplasts. Kranz bundle sheath extensions are also present. The chlorenchyma tissue is also located in this narrow peripheral zone and is interrupted by the vascular bundles and their associated sclerenchyma. Dispersed throughout the chlorenchyma are small groups of Kranz distinctive cells, identical in structure to the outer bundle sheath cells. No chlorenchyma cell is. therefore, more than two cells distant from a Kranz cell. The structure of the chlorenchyma and bundle sheaths indicates that the C4 photosynthetic pathway is operative in these culms. This study clearly demonstrates the presence of the peculiar distinctive cells in the culms as well as in the leaves of Arundinella. Also of interest is the presence of an inner bundle sheath in the vascular bundles of the culm whereas the bundles of the leaves possess only a single sheath. It has already been shown that Arundinella is a NADP-me C4 type and the anatomical predictor of a single Kranz sheath for NADP-me species, therefore, either does not hold in the culms of this genus or the culms are not NADP-me. -
Carnivorous Plant Responses to Resource Availability
Carnivorous plant responses to resource availability: environmental interactions, morphology and biochemistry Christopher R. Hatcher A doctoral thesis submitted in partial fulfilment of requirements for the award of Doctor of Philosophy of Loughborough University November 2019 © by Christopher R. Hatcher (2019) Abstract Understanding how organisms respond to resources available in the environment is a fundamental goal of ecology. Resource availability controls ecological processes at all levels of organisation, from molecular characteristics of individuals to community and biosphere. Climate change and other anthropogenically driven factors are altering environmental resource availability, and likely affects ecology at all levels of organisation. It is critical, therefore, to understand the ecological impact of environmental variation at a range of spatial and temporal scales. Consequently, I bring physiological, ecological, biochemical and evolutionary research together to determine how plants respond to resource availability. In this thesis I have measured the effects of resource availability on phenotypic plasticity, intraspecific trait variation and metabolic responses of carnivorous sundew plants. Carnivorous plants are interesting model systems for a range of evolutionary and ecological questions because of their specific adaptations to attaining nutrients. They can, therefore, provide interesting perspectives on existing questions, in this case trait-environment interactions, plant strategies and plant responses to predicted future environmental scenarios. In a manipulative experiment, I measured the phenotypic plasticity of naturally shaded Drosera rotundifolia in response to disturbance mediated changes in light availability over successive growing seasons. Following selective disturbance, D. rotundifolia became more carnivorous by increasing the number of trichomes and trichome density. These plants derived more N from prey and flowered earlier. -

Pereira 1 1 Universidade Federal do Pampa, São Gabriel, Brazil, 2 Laboratório de Palinologia da Universidade Luterana do Brasil–ULBRA, Universidade Luterana do Brazil, Canoas, Brazil This aim of this study was to distinguish grasslands from forests in southern Brazil by analyzing Poaceae pollen grains. Through light microscopy analysis, we measured the size of the pollen grain, pore, and annulus from 68 species of Rio Grande do Sul. Measurements were recorded of 10 forest species and 58 grassland species, representing all tribes of the Poaceae in Rio Grande do Sul. We measured the polar, equatorial, pore, and annulus diameter. Results of statistical tests showed that arboreous forest species have larger pollen grain sizes than grassland and herbaceous forest species, and in particular there are strongly significant differences between arboreous and grassland species. Discriminant analysis identified three distinct groups representing Edited by: each vegetation type. Through the pollen measurements we established three pollen Encarni Montoya, types: larger grains (>46 µm), from the Bambuseae pollen type, medium-sized grains Institute of Earth Sciences Jaume < Almera (CSIC), Spain (46–22 µm), from herbaceous pollen type, and small grains ( 22 µm), from grassland Reviewed by: pollen type.
