| Na de excursie naar de Langstraat en omgeving in 1961, waarvan een kort verslag te vinden is in Gorteria 1, no. 4, 1962, p. 30-31, werd in 1962 de zomerexcursie gehouden in de omgeving van Woerden van 9 tot 14 juli. In totaal werden ruim 500 soorten genoteerd in de volgende I.V.O.N.- uurhokken: 31-34; 31-35; 31-44; 31-45; 31-46; 31-54; 31-55; 38-13; 38-14 en 38-25. De zomerexcursie-1963 werd gehouden in de omgeving van Rhenen. Tijdens deze excursie, die plaats vond van 15-20 juli werden ruim 750 soorten genoteerd, waaronder vele adventieven van het graanoverslagterrein bij Wageningen. De volgende I.V.O.N.-uurhokken werden bezocht: 32-46; 32-56; 39-16; 39-17; 39-24; 39-25; 39-26; 39-27; 39-36; 39-46 en 39-47. |

| Two Pycnogonida only have been collected during the cruises of the meteorological vessel ”Cirrus” in deep plankton tows, but both specimens, each belonging to a different species, proved to be of considerable interest. I am indebted to Mr. C. L. Bekkering and Mr. S. D. Koning, who presented this precious material to the Zoölogisch Museum, Amsterdam. The one specimen belongs to a relatively well-known species, Callipallene acus (Meinert, 1898). On the basis of this material, our knowledge on the external morphology of this species, more particularly on the polymorphism in the legs, could be extended. |

| Hobart Clark, A.. |
| INTRODUCTION Mr. Austin Hobart Clark, a personal friend of Dr. H. Boschma and during many years curator of the collections of Echinoderms in the U.S. National Museum (Smithsonian Institution), died on October 28, 1954, before his study of the collection of Ophiuroidea from the Snellius Expedition could be completed. A large part of this collection, identified by Mr. Clark, is now preserved in the Rijksmuseum van Natuurlijke Historie, Leiden; a minor portion of the Ophiurid collection still awaits its revisor. Amongst the identified material there are two new species, the descriptions and drawings of which were finished by Mr. Clark before his decease. These were found amongst papers of the late Mr. Clark in the U.S. National Museum by Dr. Fenner A. Chace,... |

| Lâminas de pinho-do-paraná (Araucaria angustifolia Bert), comumente empregadas como recipientes para mudas de café, foram submetidas a tratamento com preservativos diversos. Utilizaram-se, em várias concentrações: sulfato de cobre, mistura cromo-arseno-fluo-fenólica, creosôto e óleo usado de motores. A eficiência dos preservativos foi, em ordem decrescente: creosôto, mistura de creosôto e óleo usado de motores, respectivamente nas proporções 20:80 e 50:50, óleo usado de motores, sulfato de cobre a 3%, mistura cromo-arseno-fluo-fenólica e sulfato de cobre a 1,5%. Não foi observado qualquer efeito tóxico das substâncias preservadoras, sôbre as mudas de café. |

| The superfamily Tortricoidea, the so-called leaf-rollers, contains a group of exceptionally large and conspicuously coloured species, forming the chiefly Central Asiatic Cerace group. Superficially these species do not resemble other leaf-rollers very closely. Consequently several authors placed them incorrectly: Butler (1881), Warren (1888) and Cotes (1889) in the Lithosiidae, Snellen (1903) in the Tineidae, Meyrick (1907) originally in the Plutellidae. But Walker (1863) and also Moore (1888) recognised their Tortricoid character and later also Meyrick (1908) came to the same conclusion. However, the true systematic position of the Cerace group within the superfamily Tortricoidea appeared to be even more puzzling, and subject to considerable controversy.... |

| Order Heterostomata, a large group of flatfish, has always played an important economic role in fisheries around the world. Its numerous representatives have either a wide distribution or a very localised distribution. In this group, the genus Lepidorhombus presents two species that are found on the European continental shelf in the Atlantic Ocean and the Mediterranean Sea. It has never been particularly fished but it nevertheless has a certain economic importance because it is caught in trawls along with commercial species. In the past, this fish had not received any particular attention and had not been extensively studied, excepting the works by Cligny (1905), Couch (1877), Fulton (1890-1905), Kyle (1900-1913) and Norman (1934). Furnestin (1935)... |

| American farmers have a wealth of research data available to them. Much of the data is concerned with technical problems of increasing yields, improving quality and reducing costs. In nearly all instances the improved practices can be applied by a farmer only at a cost. The farmer must decide if the improvement in output, quality or efficiency is enough to justify the extra cost, or more likely, must decide to what extent these practices should be applied. The extent to which any single agricultural input should be used cannot be determined without considering the use and effect of other inputs and the costs of all inputs and the price of the product. This publication is concerned with the amounts of nitrogen and irrigation water to use in... |

| It is a well-known saying that first brains should come, then books, then bricks. As for Malesian botany, emphasis lies for a moment clearly on bricks. But however useful they are, and coming first in abundance at that, we firmly keep our conviction that they come last in importance. Much as we enjoy the building activities which are going on in botanical institutes, yet we will review the main events of the year in the rightful order. BRAINS. We lost two of our outstanding colleagues and friends, first died Dr Ch. Baehni, who in his capacity as the Director of the Geneva Herbarium, has done much to support and cooperate with our enterprise. Later died Dr K.B. Boedijn, one of the prominent members of a generation of mycologists who still had a... |

| Soest, J.L. van. |
| De violette vlekjes, vaak langwerpig van vorm, schijnen mij toe niet van pathologische aard te zijn. Kleur en wijze van gevlektheid doen veel denken aan wat bij verschillende soorten van de Compositae (Liguliflorae) voorkomt, b.v. bij een aantal vertegenwoordigers van de geslachten Hieracium en Taraxacum en voorts bij Hypochaeris maculata. In 1963, toen het terrein, waar ik het jaar daarvoor de vorm aantrof, braak lag, heb ik geen gelegenheid gehad ernaar uit te kijken. In 1964 zal ik echter trachten de planten terug te vinden en eventueel door uitzaaien in cultuur te nemen. |
