| During the year 1948, Mr. W. H. Schuster, Laboratory of Inland Fisheries, Buitenzorg (Bogor), sent samples for determination from coastal saltwater-ponds kept for raising Chanos chanos (bandeng). Cyanophyceae have proved to form an important ingredient of the diet of the bandeng-fry. The cooperation in studying the thick layer of Cyanophyceae on the bottom of the ponds stopped at the end of the year, since difficulties of transport arose. The names of the identified species were published previously (Schuster 1949). The present author wishes to draw attention to the Cyanophyceae communities of two ponds with different vegetation. The data concerning these ponds were received from Mr. Schuster. |

| Evidemment la flore algologique du Golfe de Naples a été étudiée, d’assez près, tant du point de vue floristique que du point de vue écologique. Surtout FALKENBERG (1879), BERTHOLD (1882) et FUNK (1927) se sont occupés des investigations de cette nature. Il reste cependant un certain nombre de genres, qui demandent une étude plus approfondie. Un de ces genres est sans aucun doute Bryopsis pour laquelle il est difficile de limiter les espèces à cause de leur grande variabilité. Voici comment HAMEL (1930) se prononce sur ce genre: «D’ailleurs, les Bryopsis méditerranéens sont loin d’être connus; le peu que nous en savons est dû aux observations de J. Agardh; toute leur étude serait à reprendre sur le vivant.» FELDMANN (1937) y ajoute: «La classification des... |

| A number of samples from salt-pans collected by J. Rooth in Bonaire and by Miss T. M. Emeis in Curasao were handed over to the author for identification. Frémy (1941) has published a list of Cyanophyceae collected by Wagenaar Hummelinck in Bonaire, Klein Bonaire and Curaçao in 1930 and 1932. Among the last mentioned collection there were samples from the same salt-pans in Bonaire, where also J. Rooth did his collecting. It is interesting to compare both results. Dr Fr. Drouet had the kindness to procure some identifications for this part as well as for part II. |

| The region, from which the Vernonieae and the Eupatorieae have been worked out, includes the Greater Sunda Islands, the Lesser Sunda Islands and the Moluccas. It is a well-known fact, that the Malay Peninsula and the Philippines have a flora, which is related to that of the Malay Archipelago, sensu stricto, belonging to the same region indeed. The Compositae of these parts have, however, been recently dealt with by RIDLEY (Fl. Mal. Pen. II, 1923, 177) and by MERRILL (Enum. Phil. Flow. Pl. III, 1923, 591) respectively, whereas those from New Guinea, which is floristically less related to the Malay Archipelago, have been worked out by MATTFELD (Engl. Bot. Jahrb. LXII, 1929, 386). The material, used for this paper, chiefly belongs to the National Herbarium... |

| In het Jaarboek van de Vereniging tot Behoud van Natuurmonumenten in Nederland van 1923-1928, p. 133-142, vermeldt Prof. Stomps een aantal soorten van wieren, die gedurende 40 tochten zijn verzameld. Op een excursie, die op 4 juni jl. door Mevr. A.J. Gorter – Ter Pelkwijk en mij werd gemaakt, werd geen van deze soorten aangetroffen, tenzij zij nog te vinden zijn onder de tot nu toe niet gedetermineerde Cladophora-, Oedogonium- en Spirogyra-soorten. Op deze excursie werden gevonden: CYMOPHYCEAE: Nostoc sphaericum Vauch. ex Born, & Flah. – Veertig Morgen, drijvend. Lyngbya kützingii Schmidle – Veertig Morgen, op tussen Ranunculus (Batrachium) drijvende Cladophora. CHLOROPHYCEAE: Chaetophora elegans (Roth) Ag. – Veertig Morgen, op Bladsteel van Nuphar... |

| A collection of samples containing algae from the salines of Bonaire was brought home by Mr P. Wagenaar Hummelinck from his trips to the Netherlands West Indian Islands in 1930 and in 1936—1937. Though these trips were chiefly undertaken in order to gather zoological material (1, 2) 1), the collector paid attention to botanical objects as well, results of which are to be found in eight earlier papers (3—10). Several data concerning Bonaire can be learned from Mr Wagenaar Hummelinck’s publications. The island, having an area of about 265 km2, is chiefly composed of quaternary limestone (coralrocks), which forms a large plateau in the North East and the South. The Northwestern part of the island is much higher and more indented. Klein Bonaire, having an area... |

| Pendant une tournée du chalutier ”De Lanessan“ de l’Institut Océanographique de Nhatrang (Annam) vers le récif Tizard¹) en avril 1936, une collection d’algues marines a été constituée, provenant des îlots Itu-Aba, Sand Caye et Nam Yit. La situation de ces îlots est environ 10° de latitude Nord et 114° de longitude Est. Qu’il me soit permis de remercier M. R. Serène de l’Institut Océanographique de l’Indochine à Cauda par Nhatrang, qui m’a confié l’étude de cette collection. |

| Anne Antoinette van Bosse, fille de M. Jacob van Bosse et de Mme Jaqueline Jeanne née Reynvaan, naquit à Amsterdam le 27 mars 1852. Très jeune encore elle perdit sa mère; sa soeur, son ainée de 10 ans, prit sa place aussi bien qu’elle put. Outre cette soeur elle avait trois frères. Selon l’usage de cette époque les familles aisées n’envoyaient pas leurs filles à l’école, ainsi Anna van Bosse reçut à la maison son instruction par une institutrice de nationalité suisse. La botanique et la zoologie furent d’emblée ses branches préférées; les fréquentes visites au jardin zoologique ”Artis“ y contribuèrent pour une grande part. l’Observation des animaux exotiques lui procurait un grand plaisir et jusqu’à présent elle porte un grand intêret à ”Artis“. |

| A fungus belonging to the genus Lagenidium (Phycomycetes), according to Dr. F. K. Sparrow probably L. gracile Zopf, was found parasitizing a species of Spirogyra, probably S. setiformis (Roth) Kütz. It was collected in a ditch with turbid water near Wageningen. The young zygospores of the Spirogyra appeared arrested in their development or even destroyed by the fungus. The fungous thallus consists of coralloid, 5-8 µ wide, dispersedly septate hyphae. Extramatrical discharge tubes of the sporangia occurred. Several Spirogyra cells contained thick- and smooth-walled resting spores of the fungus, 18-21 µ in diameter. |

| In West as well as in East Java a Cyanophyceae association has been found, that from both localities shows a remarkable similarity in composition. Both were growing on limestone rocks and had the same greyish velvety appearance. The localities are: West Java, Koeripan near Buitenzorg, alt. ± 200 m (LüTJEHARMS n. 5461, 4 VII 1936) and East Java, Malang, South coast, South of Wlingi near kampong Nglijep, alt. 0—500 m (GROENHART s.n., 4 X 1936). The principal components are: Scytonema Hofmanni AG., Schizothrix chalybea (KüTZ.) GOM. and less frequent Scytonema (Petalonema) crassum NAEG. |

| Among the extensive collections of algae made by Dr P. Wagenaar Hummelinck (Utrecht) in the Antilles and adjacent regions during the years 1930, 1936, 1937, 1948—1949, 1955, a number of chiefly brackish, but also freshwater, Cyanophyceae were incorporated. This collection was kindly committed for study to the author. She is indebted to Dr F. Drouet, who identified part of it. Most of the localities have been amply described by the collector (1940, 1953), who also included pictures of several localities in the same papers. The map illustrating this paper was drawn by the collector. He also was so kind as to complete the descriptions of the localities in the present paper. |

| Together with the class of the Schizomycetes (bacteria) the Cyanophyceae belong to the division of the Schizophyta which division differs from all other plant divisions by lacking a nucleus. However, the central part of their cells is a nuclear equivalent (Procaryota). This nucleoplasm or centroplasm or central body in the Cyanophycean cell has been studied profoundly these last fifteen years (Beck, Bowen, Cassel, Fuhs, Giesy, Herbst, Hutchinson, Jensen, Jost, Pankratz, Rabinovich, Sun and others) by means of the electron microscope. The resulting papers are mostly beautifully illustrated by electron micrographs. Pure cultures of Chroococcales (Gloeocapsa, Gloeothece, Pleurocapsa) as well as Hormogonales (Anabaena, Nostoc, Microcoleus, Oscillatoria,... |
