| The Ascomycota classified in the Eurotiales, Gymnoascales, and Onygenales are considered to belong to a single order Eurotiales, which includes 4 families, based on the shape, size, and symmetry of the ascospores. The Eurotiaceae and Gymnoascaceae have dorsiventrally flattened ascospores, the Onygenaceae have elongated ascospores, and those of the Amauroascaceae are spherical or nearly so. Spherical or obovate-saccate, thin-walled, unitunicate asci, aseptate, hyaline, or pale ascospores without germ pores, and the absence of ostiolate or discoid ascomata are characteristic of all Eurotiales (and the Erysiphales and Dipodascaceae). Anamorphs are often predominant; the conidia develop from meristematic hyphae, are often catenate and separate from each other... |

| Fourteen species and one subspecies of the fern genus Hypolepis Bernh. are recognised in the Malesian and Pacific regions, excluding Australia and New Zealand. Three species, H. hawaiiensis, H. malesiana and H. scabristipes, and one subspecies, H. elegans subsp. carolinensis, are described for the first time. Two widely misapplied names, H. punctata (Thunb.) Mett. and H. tenuifolia (Forst. f.) Bernh. are more clearly defined. Descriptions, distributional data and a key for identifying all fourteen species are provided. Five species, H. alpina, H. archboldii, H. bamleriana, H. malesiana and H. scabristipes, are confined to the Malesian region; four species, H. brooksiae, H. pallida, H. polypodioides and H. punctata, extend also to the Asian mainland; three... |

| In Malesia and Australia there are nine species of Oryza L. (Gramineae). Oryza meyeriana (Zoll. & Mor.) Baillon has two varieties. Oryza schlechteri Pilg. is only known from Irian Jaya (Indonesian New Guinea). Oryza australiensis Dom. and O. meridionalis Ng are endemic to Australia. The numerous forms of O. sativa L. have not been treated. Oryza rufipogon Griff., supposedly the wild progenitor of O. sativa, is considered as a distinct species. The name for the subfamily Oryzoideae is validated. |

| Scanning electron microscope studies of the indumentum of Cissus adnata Roxb., C. assamica (Laws.) Craib and C. aristata Blume, show that the structure of the trichomes varies between taxa but is consistent within each taxon. These three species are distinct and easily recognised by the nature and distribution of these trichomes although they have been frequently confused in the literature with respect to their circumscription and synonymy. Cissus adnata, which extends from India to Australia, has both multicellular, uniseriate and unicellular 2-armed trichomes on the abaxial leaf surface, glabrous stipules and pubescent ovary; C. assamica found from India to New Guinea has unicellular, 2-armed hairs sparsely distributed, glabrous stipules and ovary; C.... |

| In Australia, New Guinea and the southwestern Pacific seven taxa are recognised in Sonneratia, of which three species are redescribed in view of their Indo-Malesian counterparts ( S. alba, S. caseolaris, S. ovata), one species is redescribed from its most likely Indo-Malesian equivalent (S. lanceolata, being distinct from S. caseolaris), one widespread hybrid is fully described (S. x gulngai being the putative synonym of S. alba x S. caseolaris), and two other hybrids (S. alba x S. gulngai, S. alba x S. lanceolata) of very limited occurrence are described as sub-units of their closest ‘parental’ forms. A key, descriptions and full synonymy are given as well as 2 distribution maps, 6 other figures and one table. |

| This paper contains a taxonomic revision of the Bulbophyllinae, with the genera Bulbophyllum (including Cirrhopetalum and Megaclinium) and Chaseella, from continental Africa (including Bioko (Fernando Poo), Sao Tome, Principe, Annobon and Zanzibar). Keys are given to the genera and species. For each species full synonymy, descriptions, notes on distribution, habitat etc. and a line drawing are presented. Many species are also illustrated by colour photographs. Three new taxa are described: Bulbophyllum subligaculiferum, B. bidenticulatum ssp. joyceae and B. scaberulum var. crotalicaudatum. Some new combinations are made. The botanical terminology used is clarified. |

| Economists are frequently faced with the task of valuing commodity package components. The valuation of specific impacts of public policies is a case in point. Two contingent market bid elicitation procedures were tested for valuing changes in single components of multicomponent government program. Results of the test suggested that respondents provided more accurate component to piecewise valuation when a two-step bidding approach, rather than a one-step approach was used. Thus, there is evidence that a two-step approach which helps respondents to isolate valuations for package components is perhaps a preferable bid elicitation procedure for piecewise valuation. |

| Fez-se o levantamento florístico da vegetação arbórea da floresta mesófila do Parque Estadual do Morro do Diabo, Município de Teodoro Sampaio, Estado de São Paulo (22º30'S, 52º20'W) pelos métodos de quadrantes e parcelas, incluindo as árvores com diâmetro à altura do peito igual ou superior a 10 cm. A utilização dos dois métodos deu-se em função das características fisionômicas, solo e drenagem dos locais amostrados. O método de quadrante envolveu 462 pontos com intervalos de 30 m., e o método de parcelas ca. 26.900 m² (ca. 2,7 ha.). Os parâmetros fitossociológicos serão abordados em futuros trabalhos. Os dados florísticos subsidiaram o reassentamento dos grupos faunísticos, em especial o Leontopithecus chrysopygus Mikan, 1823 (mico-leão-preto), dentro das... |

| The century-old law of the minimum proposed by von Liebig was tested using five independent sets of crop response data on wheat, corn, cotton, silage, and sugar beets. The rival models were polynomial functions reported in the literature as the most suitable models for interpreting those data. Overall, the von Liebig model performed very well. While the nonnested hypothesis test was inconclusive with regard to silage and sugar beets, the von Liebig model rejected the polynomial specifications for wheat, corn and cotton. |
