| Of forty-eight sandy beach samples from the Korean coasts, twenty-two contained dogielinotid Amphipoda, including four new species of the genus Haustorioides Oldevig, 1958: H. koreanus n. sp., H. latipalpus n. sp., H. nesogenes n. sp., and H. indivisus n. sp. A key to this genus, notes on morphology, distribution and ecology of these four species, and a reconsideration of the genus Eohaustorioides Bousfield & Tzvetkova, 1982 are provided. Characters considered of major diagnostic importance are found in maxilliped, maxilla 1, gnathopods, pereiopods 5, 6 and 7, pleopods, uropods, epimeral plates, oostegites, and telson. |

| The material dealt with in this second part of "Octocorallia from the Malay Archipelago" comprises mainly specimens belonging to the family Nephtheidae. Most of these nephtheids were obtained during the cruise of the "Willebrord Snellius". In addition to this material I examined some specimens collected by the Siboga Expedition, which had to be identified or described again. Besides, there were in the Leiden Museum some unidentified colonies, obtained in Malayan waters. These, too, are now recorded. Several authors have already pointed out how difficult it is to identify Dendronephthya, owing to the unsatisfactory description by some previous authors, and because of the great number of variations within the same species. Suffice it to refer to the... |

| Lathraea clandestina L. op Voorne. In april 1971 deelde de heer Willems, hoofdopzichter bij „Het Zuid-Hollands Landschap” mij mede een vreemde plant te hebben gevonden in het gedeelte van de Tenellaplas, dat als instructief plantsoen wordt beheerd. Een vierkante meter was ermee bedekt. Het bleek Lathraea clandestina L. te zijn, een soort die ik 5 jaar geleden uit Spanje meebracht en plantte of uitzaaide op de wortels van een els. Afgewacht moet worden of de plant de volgende winters zal doorstaan. De dichtstbijzijnde groeiplaats ligt in België, nl. in de provincie Oost-Vlaanderen. |

| Evenals in voorgaande jaren zullen ook in 1989 weer een aantal zaterdagexcursies worden georganiseerd. Ditmaal zal ernaar worden gestreefd zoveel mogelijk per fiets of te voet te gaan. De excursies beginnen om 10 uur en worden omstreeks 4 uur beëindigd. Voor april 1989 staan de volgende drie excursies op het programma: — 8 april: Vertrekpunt Station Nijmegen, waar fietsen kunnen worden gehuurd (legitimatie en ƒ 50.- borg meebrengen). Excursiedoel is de heuvelrand van Beek-Ubbergen, waar onder meer Gevlekte dovenetel ( Lamium maculatum), Vingerhelmbloem ( Corydalis solida) en Paarbladig goudveil (Chrysosplenium oppositifolium) in bloei te verwachen zijn. Voor fijnproevers zijn er Heggevogelmuur ( Stellaria neglecta) en Heelbeen (Holosteum umbellatum) om... |

| Six new species and three new subspecies of Lunatipula Edwards are described respectively characterized. The geographical variation of some species is illustrated. The new taxa are: Tipula (Lunatipula) iberica spimila from Morocco, T. (L.) capra from Italy, T. (L.) profdrassi and T. (L.) monstrabilis from Greece, T. (L.) brunneinervis sinedente, T. (L.) emmahelene, T. (L.) pseudolunata pseudolunata and T. (L.) quinquespinis from Turkey and T. (L.) pseudolunata spinalonga from Russia. Also presented are the supposed females of T. (L.) leda Mannheims, (L:) dracula Theischinger and T. (L.) charybdis Theischinger. It is established that T. (L.) polyhymnia Theischinger is the female and therefore a junior synonym of T. (L.) leda Mannheims and that T. (L.) pan... |

| In deze oecologische studie wordt een beschrijving en analyse gegeven van het milieu van de plantensoort Centaurium vulgare Rafn (Duizendguldenkruid). Voorzover mogelijk wordt aangetoond hoe de verspreiding en de wijze van voorkomen van deze plantensoort bepaald worden door de milieufactoren. Het onderzoek is gebaseerd op gegevens verzameld in het veld, vooral in de duinen en op de kwelders van het eiland Terschelling. Centraal in het onderzoek stond het object Centaurium vulgare, waarvan verschillende facetten besproken worden zoals de nomenclatuur, de morphologie, de levensloop, de variabiliteit en het areaal. De volgende belangrijke punten uit deze bespreking kunnen genoemd worden: De levenscyclus van Centaurium vulgare duurt twee jaren. Naast de... |

| In the Netherlands, usually only one Leucanthemum species is recognised, L. vulgare Lam. Recent field observations suggest that the Leucanthemum species that occurs abundantly in the Netherlands is the tetraploid species L. ircutianum DC instead. A few Dutch specimens in the herbarium collection of Naturalis in L, however, have been identified as belonging to the 'true' diploid L. vulgare. The latter seems to be rare in the Netherlands, and might be confined to a few relict populations. In Nederland word slechts één Leucanthemum-soort onderscheiden die hier bekend staat onder de naam L. vulgare Lam., een diploïde soort. Op basis van veldobservaties moet echter worden geconcludeerd dat de algemeen voorkomende Margriet in Nederland waarschijnlijk de... |

| A. Espèces à cercle facial assez distinct. Se trouvent dans toutes les parties du monde. Il paraît que dans celles qui habitent exclusivement l’hémisphère austral et les tropiques, la livrée parfaite des femelles adultes est absolument semblable à celle des mâles adultes; dans les autres espèces, le mâle adulte offre un système de coloration très différent de celui de la femelle adulte, qui ressemble sous ce rapport aux individus des deux sexes dans la première livrée. Elles habitent de préférence les plaines. Sousgenre Strigiceps de Bonaparte. CIRCUS CYANEUS, Bechstein. — Falco cyaneus, Linné. |

| The genus Galaxaura can in several respects be classed among the most remarkable Florideae. It is not only — with Chantransia — the genus richest in forms of all the genera belonging to the order of Nemalionales, which has more than 70 described species, it also offers, both in its interior and its exterior organization, such a high differentiation, and a tissue specialization going so far, that, as the monographer of the genus, the late Professor F.R. Kjellman (1900), said: ”it may be difficult even in the great province of the Florideae to find forms with a higher or even as high a division of labour in the tissues of the shoot...“. Even if the number of species may actually diminish with further investigations, this is in a way connected with a... |

| Two species of sea anemones with a conspicuous marginal ruff of frond-like structures encompassing the tentacular crown occur on the Chilean coast. Oulactis concinnata (= Isoulactis chilensis) (Drayton in Dana, 1846) is re-described in detail and further information is provided for Oulactis coliumensis (Riemann- Zürneck & Gallardo, 1990) (= Saccactis coliumensis) (both Actiniidae). The distribution of O. concinnata from Playa Las Salinas, Perú (9°19’10’’S, 78°26’30’’W), to the region of Valdivia, Chile (39°47’S, 73°21’W), lies within a zoogeographical unit known as the Peruvian Province. Re-description of O. concinnata is based on examination of 10 specimens collected between 1975 and 2003, and on observations of about 50 living anemones in their... |

| The new checklist of Dutch liverworts comprises 126 species, 1 subspecies and 5 varieties. Since 1962 seven liverwort species have been added to the flora: Barbilophozia hatcheri, Calypogeia muellerana, Cephalozia pleniceps, Fossombronia incurva, Haplomitrium hookeri, Lophozia perssonii and Plagiochila porelloides. Of twelve species presumed occurrence in the Netherlands needs verification. Nomenclature follows Grolle’s “Verzeichnis der Lebermoose Europas” (Feddes Repert. 87: 171-279. 1976), except for Isopaches, Leiocolea and Microlejeunea, which are maintained as genera and Phaeoceros carolinianus, Cephalozia lammersiana, Chiloscyphus pallescens, Lophozia silvicola and Lophocolea cuspidata. , which are treated as intraspecific taxa. |

| Some genera of Geoglossaceae, characterized by colourless spores and positive iodine reaction of the ascus pore, are compared with respect to the structure of the stipe. Ochroglossum is reduced to the synonymy of Microglossum. Mitrula is regarded as a monotypic genus. The generic name Heyderia is restored. Thuemenidium is reintroduced to replace Corynetes. Nothomitra is proposed as a new genus to accomodate N. cinnamomea, a new species. |

| The copepodite antennule development of representatives of 6 harpacticoid families is studied and discussed in detail and that of 8 genera of harpacticoids from 7 families is schematically illustrated. Twenty-seven genera out of 17 harpacticoid families are compared on the basis of own investigations and data from the literature. The origin of newly formed segments can be determined by seta numbers of segments, relative segment length, furrows indicating previous articulations and by the position of the segment which bears the proximal aesthetasc. There are 2 zones of segment formation, both located in the middle part of the first antenna. Normal segment formation takes place distally from the second, aesthetasc-bearing segment from C I to C II and... |

| The author describes the occurrence of Goodyera repens in a forest near Appelscha (Friesland). This species was found during an investigation of this forest, called Beatrixoord, on behalf of a management and maintenance plan. This area was visited three times and each time Goodyera was found in different parts of Beatrixoord. Goodyera is a rather rare orchid in the Netherlands. The species occours in pine woods on dry sandy soils. In Germany however the species is also found on calcarious soil accompanied by species such as Cephalanthera rubra, Plantanthera chlorantha and Epipactis atrorubens. In the Netherlands Goodyera is accompanied by species of the Vaccinio-Piceetea like Vaccinium vitis-idaea, Listera cordata, Linnaea borealis, Pyrola minor and... |
