Provedor de dados: 16
Autores: Ham, R.W.J.M. van der.
The aim of this book is stated as “to introduce the minute and mysterious world of pollen to as many readers as possible” and “to re-establish the morphological study of pollen taking into account newly accumulated phylogenetic information”. It provides introductory accounts on ontogeny, pollen morphology, pollination, pollen physiology, genetics of pollen, airborne pollen and pollinosis, and pollen analysis. Technically speaking it is a well-produced book, being bound in hard covers and neatly printed on good paper. Moreover, it is overwhelmingly illustrated. However, when looking and reading carefully through the book one gets a bit disappointed. Let us first consider the illustrations, which take up at least three quarters of the book. In general, the...

Evolutionary trends in the morphology and harmomegathy of the pollen of the genus Guioa (Sapindaceae-Cupanieae)
Provedor de dados: 16
Autores: Ham, R.W.J.M. van der; Heuven, B.J. van.
A pollen morphological survey of the genus Guioa is presented. Based on a study of the harmomegathy in relation to morphological series, evolutionary trends are postulated: 1. wide ectoapertures → narrow ectoapertures 2. grain parasyncolporate → grain colporate 3. grain parasyncolporate → grain syncolporate 4. ornamentation rugulate → ornamentation psilate-imperforate. It is suggested that the most ‘primitive’ species of Guioa occur in the southeastern part of the distribution area of the genus. Guioa can be subdivided into four poorly delimited pollen morphological groups. Its affinities to other genera in the Cupanieae are briefly discussed. Pollen of the most ‘primitive’ group is similar to that of several ‘primitive’ genera (e.g. Arytera, Matayba,...

Daphne laureola L. (Zwart peperboompje) in Nederland
Provedor de dados: 16
Autores: Ham, R.W.J.M. van der; Meijden, Ruud van der.
In the last years isolated specimens of Daphne laureola have been found in three localities in the Netherlands: one in the dunes of Voorne, and two in public gardens in Delft. Daphne laureola is only rarely cultivated in the Netherlands. It is argued that the Dutch localities might belong to a more or less natural extension of the distribution area of this species, which might be associated with the still ameliorating climatic conditions for atlantic-mediterranean species in the Netherlands.

Notes on Arytera (Sapindaceae)
Provedor de dados: 16
Autores: Ham, R.W.J.M. van der.
Consequently upon a revision of Mischocarpus (Van der Ham, 1977a), a detailed study has been made of several characters in Arytera in order to get a better understanding of the delimitation of the two genera mutually. The differences between Mischocarpus and Arytera given by Radlkofer (1931) in his key are vague and can only be used when fruiting material is available. However, several species in Arytera were described by him and others on flowering material only. Two species of Mischocarpus could be connected with species of Arytera. One species of Arytera appeared to be the same as Mischocarpus exangulatus. M. exangulatus has, besides typical Mischocarpus characters, several features unique in Mischocarpus but more regularly occurring in Arytera....

Een nieuwe desinfectiemethode voor herbaria. Droog organisch materiaal oefent een grote aantrekkingskracht uit op allerlei dierlijke organismen. Gedroogde planten, het herbarium, maken daarop geen uitzondering en worden met graagte door verschillende insektesoorten gegeten. Vooral de z.g. museumkevers worden nogal eens in collecties aangetroffen. Iedereen, die er een herbarium op na houdt, weet, dat regelmatige controle en desinfectie van zijn collectie noodzakelijk zijn. Het controleren van vele, soms duizenden of tienduizenden, exemplaren is een tijdrovend, zij het niet altijd onplezierig karweitje. Het desinfecteren van een collectie kan echter wel onplezierig zijn. Om een herbarium insektenvrij te houden, wordt tot nu toe gewerkt met bepaalde...

Teucrium chamaedrys L. subsp. chamaedrys in Nederland
Provedor de dados: 16
Autores: Ham, R.W.J.M. van der.
The occurrence of Teucrium chamaedrys subsp. chamaedrys in the Netherlands is discussed. Since 1905 this subspecies has been present in one locality in the dunes south-west of Haarlem. Probably it was imported there with pheasant fodder. The plants maintain themselves easily but seem to be unable to make ripe seeds. As this subspecies has not yet spread, it is not included in the flora of the Netherlands.

Autores: Ham, R.W.J.M. van der.
During a revision of herbarium material of the genus Barbarea, it became apparent that Barbarea intermedia Bor. is much more common in the Netherlands than was supposed. It is probably a native rather than a casual species although it may have been introduced long ago. Barbarea verna (Mill.) Aschrs., usually thought of as a rare native species, appears to be merely a casual in the Netherlands.

Pollen morphology of the Stemonaceae
Provedor de dados: 16
Autores: Ham, R.W.J.M. van der.
A pollen-morphological survey of all four genera of the Stemonaceae at the light and electron microscope level is presented. Stemonaceae is a eurypalynous family. Stichoneuron pollen, up to now described as monosulcate, appears to be inaperturate. Pentastemona pollen is most deviating in Stemonaceae. Its sexine consists of elements that resemble Ubisch bodies very much. It shares several features with pollen of Peliosanthes (Convallariaceae) and Trillium (Trilliaceae). However, the closest relatives of Pentastemona could not be traced with the available pollen-morphological evidence.

Pollenmorphology of the genus Mischocarpus (Sapindaceae)
Provedor de dados: 16
Autores: Ham, R.W.J.M. van der.
The pollen morphology of all 11 species of the genus Mischocarpus is studied. All species possess basically the same syntricolpate pollen type. Transitions to the tricolpate type were observed rarely. Within the syntricolpate type, subtypes could be established. For a few species a rather wide range of variability in some characters is described. Pollen morphology correlates with macromorphology as well as with geography, thus supporting the results, based on macromorphological evidence, concerning infrageneric structure and relationships of Mischocarpus.

Autores: Sierra, S.E.C.; Aparicio, M.; Kulju, K.K.M.; Fišer, Ž.; Welzen, P.C. van; Ham, R.W.J.M. van der.
A recent phylogenetic study based on DNA sequence data detected a well-supported clade of a number of Mallotus species together with the genus Cordemoya. This clade is distinct from the large Mallotus s.s. clade. In this paper, Cordemoya (formerly monotypic with C. integrifolia from the Mascarene Islands) is expanded with sixteen additional species previously assigned to Mallotus. Taxa transferred to Cordemoya are: Mallotus sections Hancea and Oliganthae from Asia and M. baillonianus, M. capuronii, and M. spinulosus from Madagascar. The genus Cordemoya can be distinguished from Mallotus s.s. by the presence of pollen with areolate ornamentation with scabrae (perforate/microreticulate ornamentation with scabrae in the sample of Mallotus s.s. studied up to...

Cnesmocarpon (gen. nov.), Jagera, and Trigonachras (Sapindaceae—Cupanieae): Phylogeny and systematics
Provedor de dados: 16
Autores: Adema, F.; Ham, R.W.J.M. van der.
Cladistic analyses of pollen-morphological, leaf-anatomical and macromorphological data of Jagera, Trigonachras, and several new species lead to the conclusion that a new genus, Cnesmocarpon, has to be described (see the Taxonomic Part on p. 195). Two pollen types are described, one including Cnesmocarpon, the other including Jagera and Trigonachras. The morphologies of these pollen types suggest different harmomegathic systems: nonapertural and apertural folding respectively. The ornamentation of Cnesmocarpon pollen resembles that of several other Cupanieae genera. The scabrate ornamentation of Jagera and Trigonachras pollen, often provided with hair-like appendages, is unique in that tribe. Leaf-anatomically Jagera is characterised by the presence of...

This book contains the proceedings of the special tapetum symposium, held during the VIII International Palynological Congress in 1992 (Aix-en-Provence, France). Twelve contributions demonstrate the importance of the tapetum in the reproduction of land plants. As the editors state: any tapetum malfunction causes pollen sterility. All papers deal with basic research, not with applied research such as plant breeding and genetic engineering. Although ‘evolution’ is listed in the title, very little (no special contribution) is devoted to this subject. It is a pity, because a phylogenetic theory has been suggested in the past, which should be treated in a book covering such a highly and diversely specialised structure. A taxonomic survey (table) listing the...

Autores: Ham, R.W.J.M. van der; Heel, W.A. van.
Secondary pollen presentation is a taxonomically widespread phenomenon that is unknown to many botanists. As defined by the author, it embraces those cases in which pollen is transferred within the flower, and presented to pollinators on or by floral structures other than the thecae. The intraflower transfer often involves intriguing adaptations of petals, androecium and distal parts of the gynoecium. The present book is largely a case of secondary presentation itself, being actually a review of the literature on the subject, supplemented with unpublished data and drawings. The main part (208 pp.) extensively describes familywise all taxa known to have secondary pollen presentation, with many comments inserted. Papaveraceae, Leguminosae, Proteaceae,...

This project of the Royal Botanic Garden Edinburgh aims to provide regional manuals and on-line identification computer programs to the timber species of Dipterocarpaceae. The Singapore manual is a first trial, later editions should include other islands in the Malay Archipelago. The possibility is also offered to have tailor-made manuals for specific regions against cost price. Many data have been gathered, especially vegetative characters one can readily observe while standing underneath these enormous trees. In this respect the database will be very useful, because due to the very irregular flowering of the Dipterocarpaceae, flowers and fruits are usually unavailable, and even if they are present, they are found high in the tree.

Induced by too many wrongly determined specimens of Lactuca virosa L. the author discusses a number of differences with Lactuca serriola L. The fruit especially offers reliable characters (fig. 3). L. virosa probably occurs only as an alien in the Netherlands. In recent years L. serriola had a considerable expansion, particularly in the urbanized west of the country. Very often it concerns f. integrifolia Bogenhard. Nowadays, this forma seems to be more common than in former years.

Morphology and evolution of Arytera pollen (Sapindaceae-Cupanieae)
Provedor de dados: 16
Autores: Bergen, M.A. van; Ham, R.W.J.M. van der; Turner, H.
A description of Arytera pollen based on light and scanning electron microscopic observations is presented. Four aperture types and two ornamentation types (one divided into two subtypes) can be distinguished. The commonest aperture types are colporate and parasyncolporate; each of the other two types occurs in a single species. The main ornamentation types are rugulate and striate-rugulate; the latter has small or large lumina. Polymorphism occurs in both characters in several species. A cladistic analysis of Arytera shows two distinct evolutionary trends in the pollen: 1) aperture system from parasyncolporate to colporate, and 2) ornamentation from striate-rugulate with small lumina to striate-rugulate with large lumina. The plesiomorphic state of the...

Nephelieae pollen (Sapindaceae): Form, function, and evolution
Provedor de dados: 16
Autores: Ham, R.W.J.M. van der.
Two main types may be distinguished within Alectryon pollen: the colporate type and the parasyncolporate type. These types are not clear-cut, but merge into each other through a complete series of intermediate forms. The colporate type has usually a colporate apertural system, a high P/E value (av. 0.97), a low A/E value (0.32), and striate to striate-rugulate ornamentation. The parasyncolporate type shows usually a parasyncolporate apertural system, a low P/E value (av. 0.76), a high A/E value (av. 0.46), and striate-rugulate to rugulate ornamentation. In addition, there is some difference in endoaperture and nexine morphology, and the relative length of the peripheral columellae of a mesocolpium. An endoaperture in a colporate grain often shows acute or...

Pollen of Southeast Asian Alchornea (Euphorbiaceae), with an overview of the pollen fossil record

Autores: Bulalacao, L.J.; Ham, R.W.J.M. van der.
In order to evaluate pollen morphological descriptions of Alchornea in the literature, which are almost completely based on African and American species, the pollen of eight Southeast Asian species of Alchornea was investigated, using light and scanning electron microscopy. Very little variation appeared to be present in the Asian material. Slightly deviating from the scabrate ornamentation type are A. kelungensis (psilate) and A. rugosa (striate-rugulate). The scabrate type is also found in A. castaneaefolia (Brazil), A. hirtella (Liberia) and A. obovata (Colombia). The operculate Alchornea pollen type, which can be easily recognised using light microscopy, seems to represent a diagnostic character for the tribe Alchornieae (pollen of Bossera unknown)....

Is Viburnum lantana L. indigeen in de duinen bij Haarlem?

Autores: Ham, R.W.J.M. van der.
The occurrence of Viburnum lantana in the Netherlands is discussed, with reference to the identification of a shrub belonging to this species in the painting 'Dunes by the Sea' (1648) by Jacob van Ruisdael and its naturalness in the dunes near Haarlem (Ashton c.s., 1982). Although Van Ruisdael worked most accurately in depicting trees and shrubs, he took many liberties in the composition of a painting. As V. lantana was already cultivated in his century, it is possible that he saw the species in cultivation and then 'introduced' it in 'Dunes by the Sea'. All other records of the species in the vicinity of Haarlem point to an origin as garden escape.
