Olyra amapana soberstr & Zuluaga (Bambusoideae: Olyreae: Olyrinrae), Registro nuevo para Venezuela
Grande Allende,José Ramón;
Acta Botánica Venezuelica , 2009,
Abstract: olyra amapana is described, illustrated and reported for the first time for venezuela. the taxonomic placement of this species within the genus olyra as well as certain ecological and phytogeographical aspects are briefly discussed. o. amapana is very similar to o. juruana, from which it can be distinguished by the presence of a lower number of smaller racemes. o. amapana, o. bahiensis, o. ciliatifolia and o. juruana are bambusoid species of completely herbaceous habit and fusiform, smooth and pilose female anthecia.
Olyra bahiensis (Poaceae - Olyreae): uma nova espécie para a mata atlantica do estado da Bahia, Brasil
Oliveira, Reyjane Patrícia de;Longhi-Wagner, Hilda Maria;
Brazilian Journal of Botany , 2005, DOI: 10.1590/S0100-84042005000400017
Abstract: a new species of olyra is described and illustrated. olyra bahiensis r.p.oliveira & longhi-wagner is related to o. ciliatifolia raddi (widely distributed in south america), and to o. juruana mez, o. amapana soderstr. & zuloaga, and o. loretensis mez (occurring in the amazonian basin), sharing the presence of trichomes covering completely the female floret. the new species occurs in the atlantic rain forest of southern bahia, in the same area where other many species of grasses are found. the populations of o. bahiensis present small number of individuals, growing in shaded areas associated with cocoa plantations. an analytical key for o. bahiensis and allied species is also presented.
Olyreae (Poaceae: Bambusoideae) da Marambaia, Rio de Janeiro, Brasil
Silva, Christian da;Conde, Marilena de Menezes Silva;Longhi-Wagner, Hilda Maria;
Rodriguésia , 2012, DOI: 10.1590/S2175-78602012000200010
Abstract: marambaia is located in southern rio de janeiro state, between sepetiba bay and the atlantic ocean (23o1's, 23o6's; 43o34'w, 44ow), within the atlantic forest domain. the tribe olyreae includes the herbaceous bamboos, found mainly in the new world tropics, usually comprising the herbaceous layer of forests. they are being threatened by habitat fragmentation and degradation. this study aims to determine which olyreae species occur in the area, contributing to our knowledge of their conservation, distribution and diversity. samples were collected from august 2008 to december 2010 by free walks along trails in the various plant formations. the occurrence of seven olyreae species distributed in atlantic slope-forest areas was confirmed. subtribe olyrinae is represented by cryptochloa capillata, olyra humilis, o. latifolia, parodiolyra micrantha, raddia brasiliensis and reitzia smithii, and subtribe parianinae by eremitis sp. olyra latifolia and p. micrantha are the most common species in the area. eremitis sp. is probably a new species.
Comparative analysis of the leaf anatomy in two Parodiolyra species (Poaceae: Olyreae) occurring on forests in Eastern Brazil
Jesus Junior, LA;Oliveira, RP;Leite, KRB;Silva, LB;
Brazilian Journal of Biology , 2012, DOI: 10.1590/S1519-69842012000100025
Abstract: parodiolyra is a member of olyreae, a tribe of herbaceous bamboo species within the poaceae. the genus has five species, four of which were previously regarded as belonging to olyra l. parodiolyra has a neotropical distribution and only two species occur on forests in eastern brazil: p. micrantha (kunth) zuloaga & davidse and p. ramosissima (trin.) soderstr. & zuloaga, the first widely distributed in the neotropics while the second is endemic to the state of bahia. leaf anatomy of the two species was analysed with the aid of an optical microscope. the objective was to describe the microscopic characters and evaluate if they can be useful for the taxonomy of the genus. the observed anatomical structures did not differ from other genera of herbaceous bamboos, however some characters, both from the mesophyll and the epidermis, were useful to delimit the two species.
Desenvolvimento pós-seminal de espécies de Poaceae (Poales)
Nakamura, Adriana Tiemi;Scatena, Vera Lucia;
Acta Botanica Brasilica , 2009, DOI: 10.1590/S0102-33062009000100023
Abstract: this work has aimed to verify the existence of a pattern of the post-seminal development in poaceae. thus, olyra humilis nees (bambusoideae); axonopus aureus p. beauv. e paspalum polyphyllum nees ex trin. (panicoideae); chloris elata nees e eragrostis solida desv. (chloridoideae) have been studied. besides, it was compared the structures of poaceae seedlings with those of other monocotyledons. all are perennial, rhizomatous, and cespitous species whose caryopses differ in size. they all present albuminous seeds, lateral and differentiated embryos, with endogenous embryonic (adventitious) root, cotyledons divided into hyperphyll (scutellum), reduced sheath and hypophyll (coleoptile); coleorhiza (reduced primary root); and mesocotyl (axis between the scutellum and the coleoptile). the presence of epiblasts (embryonic leaves) was noticed in olyra humilis, chloris elata and eragrostis solida. since the post-seminal developmental of all the studied species is similar, it represents a pattern in poeaceae. the coleorhiza, which shows positive geotropism, grows first, followed by the coleoptile and the plumule, in the opposite direction, which form from the mesocotyl development. in all species, the first leaves are similar to the definitive ones (metaphyll) except olyra humilis, where they are converted into a cataphyll - probably interpreted as a basal character in bambusoideae. the reduced primary root (coleorhiza) and the hypophyll, which is modified into a coleoptile, are considered derived features in poaceae, when compared with the other monocotyledons.
Desenvolvimento de óvulo, fruto e semente de espécies de Poaceae (Poales)
Nakamura, Adriana Tiemi;Longhi-Wagner, Hilda Maria;Scatena, Vera Lucia;
Brazilian Journal of Botany , 2009, DOI: 10.1590/S0100-84042009000100016
Abstract: we selected olyra humilis nees and sucrea monophylla soderstr. (bambusoideae), axonopus aureus p. beauv. and paspalum polyphyllum nees ex trin. (panicoideae), chloris elata desv. and eragrostis solida nees (chloridoideae) to study their ovule, fruit and seed development in order to characterize the embryology of these subfamilies within poaceae. like other poaceae that have already been studied, these species present bitegmic ovule, micropyle formed by the inner integument, megagametophyte of the polygonum type, starchy nuclear endosperm, and lateral, developed embryo. in specimens of bambusoideae and panicoideae, the ovule is hemianatropous and pseudocrassinucellate, whereas in chloridoideae, it is campylotropous and tenuinucellate. the outer integument is restricted to the ovule base in bambusoideae; it reaches up to one third of the nucellus in panicoideae and extends to the micropyle in chloridoideae. o. humilis and s. monophylla (bambusoideae) present a more developed nucellus than the other species studied here. each subfamily varies with regard to its mature caryopsis type. in bambusoideae, the fruit has a phenolic endocarp and ategmic seeds; panicoideae have compressed, adnate pericarp and tegmen; chloridoideae present a free exocarp and a phenolic endotegmen. the overall features are diagnostic for the poaceae subfamilies studied here.
Anther and pollen development in some species of Poaceae (Poales)
Nakamura, AT.;Longhi-Wagner, HM.;Scatena, VL.;
Brazilian Journal of Biology , 2010, DOI: 10.1590/S1519-69842010005000005
Abstract: anther and pollen development were studied in olyra humilis nees, sucrea monophylla soderstr, (bambusoideae), axonopus aureus p. beauv., paspalum polyphyllum nees ex trin. (panicoideae), eragrostis solida nees, and chloris elata desv. (chloridoideae). the objective of this study was to characterise, embryologically, these species of subfamilies which are considered basal, intermediate and derivate, respectively. the species are similar to each other and to other poaceae. they present the following characters: tetrasporangiate anthers; monocotyledonous-type anther wall development, endothecium showing annular thickenings, secretory tapetum; successive microsporogenesis; isobilateral tetrads; spheroidal, tricellular, monoporate pollen grains with annulus and operculum. nevertheless, the exine patterns of the species studied are distinct. olyra humilis and sucrea monophylla (bambusoideae) show a granulose pattern, whereas in the other species, it is insular. in addition, axonopus aureus and paspalum polyphyllum (panicoideae) have a compactly insular spinule pattern, while chloris elata and eragrostis solida (chloridoideae) show a sparsely insular spinule pattern. the exine ornamentation may be considered an important feature at the infrafamiliar level.

Una epistemología histórica de la pedagogía: El trabajo de Olga Lucía Zuluaga
RUNGE,Andrés Klaus;
Revista de Pedagogía , 2002,
Abstract: the epistemological status of pedagogy has been debated in colombia for long and o.l. zuluaga has been a forerunner in this debate. following m. foucault?s proposals, zuluaga puts forward a rather different conception, one aimed to follow the parameters of both practice and knowing. her proposal is envisioned as a historical pedagogy which seeks to bring out pedagogy as such and to show its real being as both pedagogical knowledge and practice. as a theoretical-philosophical and methodological-investigative strategy, an object and a method, a means of simultaneous self-investigation and self-legitimation, is proposed. the goal is to furnish pedagogy with a new set of assumptions which may place this discipline within a specific realm: one not defined by the traditional parameters of science. as a consequence, pedagogical knowledge would be reconstructed in its own specificity.
