| Pages 220-279 of the International Code of Botanical Nomenclature (1956) are occupied by a list of conserved and rejected names of genera of Spermatophyta. The origins and history of conservation have been discussed by Stafleu (Taxon 5: 85-95). As a result of his study it became evident that the list is no longer in harmony with current concepts of nomenclature and the rules for maintaining them. The desirability of a general revision of the list is obvious; such a revision was begun by Stafleu several years ago. It proved, however, an impossible task for one person to achieve in the intervals between ordinary duties. Consequently application was made by The International Association for Plant Taxonomy to the National Science Foundation (Washington) for a... |

| Erismadelphus Mildbr. is remarkable because it is the only African genus of the Vochysiaceae, a family represented in tropical America by no less than 5 genera and 180 species. Erismadelphus was discovered in 1913 by Prof. J. MILDBREAD and has hitherto been represented by only one species: E. exsul Mildbr. Recent examination of the African collections has, however, revealed the existence of two other taxa. Unfortunately the type of E. exsul (Mildbraed s.n. from Elon, French Cameroons) was destroyed at Berlin during the 1939-45 war and no duplicates or cotypes are known to exist. In response to an enquiry Prof. MILDBREAD, to whom we are very grateful, informed one of us that in his view Corbisier 1362 from Eala in Belgian Congo was identical with his... |

| This publication is intended to be the first part of a taxonomic monograph of the family Vochysiaceae and deals with the genera Salvertia and Vochysia. Since Warming’s excellent treatise of the Brazilian species of this family in the Flora Brasiliensis (Vol. XIII, II,1875) a large number of new species has been described, especially from neighbouring countries, and much new material has been collected. The fact that the number of species of Vochysia has been doubled since Warming may give a raison d’être to this monograph. A large quantity of material was kindly put at my disposal by several herbaria. These herbaria are indicated in this monograph by the following abbreviations proposed by the Standing Committee for Urgent Taxonomic needs of the... |

| Joseph Gaertner (1732-1791) was the first to develop a carpological taxonomy in his book De fructibus et seminibus plantarum (1788-1791). The scope and background of this work are discussed; its history is sketched on the basis of the Banks correspondence at the British Museum; the main sources of material are listed. A brief outline of Gaertner’s life is given, also mainly based on letters from him and his contemporaries to Joseph Banks. |

| The genus Qualea is found in tropical South America, particularly in the Hylaea and in the Extra Amazonian part of the Brazilian mainland (see fig. 3); it comprises 59 species as defined in this paper. Many species are forest trees occurring in the Amazonian basin, a number are found in the Brazilian Atlantic coastal forests, whereas other species are typical trees of the campos of the interior plateau. The genus was first described by AUBLET in 1775; its name is a latinization of the vernacular name “Qualé” used by the “Caribbean” inhabitants of French Guiana. AUBLET described O. rosea (type species) and Q. coerulea; the first exhaustive and morphologically correct description was given by A. DE ST. HILAIRE (1820) who placed the genus in his newly... |

| Eén van de grote giften van A. A. Pulle, Lanjouw’s voorganger als Hoogleraar in de Bijzondere Plantkunde en de Plantengeographie te Utrecht, was zijn goede keus van medewerkers. Hij kon die keus maken dank zij een andere gift, die van leermeester. Pulle’s stimulerende activiteit als hoogleraar luidde de wedergeboorte in van de Nederlandse plantensystematiek door een stroom van leerlingen waarvan er velen ook nu nog een belangrijke rol spelen in de botanische wereld. Vele van Pulle’s leerlingen uit de eerste tijd moesten Utrecht verlaten omdat er in de twintiger jaren nu eenmaal nog geen sprake was van een redelijk gesalariëerde wetenschappelijke staf. Eén leerling echter werd zo gefascineerd door de vele mogelijkheden die het Utrechtse instituut bood, dat... |

| The genus Callisthene is found in the Extra Amazonian part of the Brazilian mainland, particularly in the zone of the campos and in the adjacent parts of Bolivia. The genus comprises eight species, as defined in this paper. It shows its greatest diversity on the central plateau of the Brazilian state of Minas Geraes. Most of the species are typical trees of the campos of the interior Brazilian plateau, which is characterized by a climate with a severe dry season. The genus was first described by MARTIUS in 1824. He mentioned all important characters and placed it in the Vochysiaceae, a family which had been described only four years earlier by A. DE ST. HILAIRE (1820). It was named after Callisthenes (360—327 B.C.), the Greek naturalist and historian of... |

| The eighth volume of Flora Malesiana is dedicated to the memory of the Dutch botanist F. A. W. Miquel, who, even though he never visited the tropics, contributed greatly to the development of the knowledge of the Malesian flora. He did so not just through his well-known Flora Indiae Batavae, but certainly also through his role in re-activating the Rijksherbarium during and following the somewhat difficult aftermath of BLUME’S reign, and in rallying the support of Dutch and foreign botanists to study the many collections from the ‘East Indies’ which reached the Netherlands in the years between 1840 and 1870. Miquel also played an inconspicuous, but as it turned out, decisive part in the introduction of Cinchona in Java and last, but not least, left an... |

| Questions of priority often necessitate a search for precise dates of publication. Much research of this kind has already been done, for instance by Britten and Woodward in their “Bibliographical notes” published in the Journal of Botany, by O. Kuntze in his Revisio generum plantarum, by W. T. Stearn in numerous publications, by Mrs. van Steenis-Kruseman in the Flora malesiana, by G. Sayre in a special book describing publications from 1801 to 1821 of importance for the nomenclature of Musci. My attention was drawn more especially to the period around 1789, the year of the French revolution, a period in which many important botanical books were published. It is sufficient to mention the names of Aiton, Cavanilles, Gaertner, Gmelin, Jacquin, Jussieu,... |

| The University herbarium of Utrecht dates traditionally from the year 1816 when a collection of about 3000 plants was bought from the professor of botany M. van Geuns (1735-1817). It is possible that other collections of dried plants were already owned by the University or at any rate by the botanic garden, before that time, but nothing is known about this. The small van Geuns herbarium, which contained collections made by J. D. Hahn, M. W. Schwencke and S. J. van Geuns, among others, may therefore be taken as the starting-point of the herbarium of the later Botanical Museum.1)*) The period, however, was not one of great botanical activity at Utrecht and the botanist who succeeded van Geuns as professor of natural history and rural economy, Jan Kops, did... |

| The genus Erisma is found in the Amazonian basin and in the Guianas; it comprises 16 species as defined in this paper, all of them typical Hylaean forest trees. The genus was first described by RUDGE in 1805; its name is a greek word meaning “a cause of dispute”. RUDGE may have wanted it to refer to the romantic story of the type-specimen of his Erisma floribundum, a specimen belonging to a set of plants collected by the Frenchman Martin in French Guiana and captured by British privateers on its way to Paris. The name was also well suited to indicate the difficult taxonomic position of the genus. |
