SABIIA - Sistema Aberto e Integrado de Informação em Agricultura (Sabiia)

In Zygogynum six species are recognized, of which two are newly described. Z. spatulatum is reduced to synonymy, Z. balansae is ranked as a subspecies of Z. pomiferum. Leaf anatomy provided suitable specific characters on which an alternative key could be constructed. Notes are given on the morphology of the inflorescence, flower, and fruit; the calyx is calyptrate in very early stages, the petals are mostly connate in bud. Corrections of identifications cited in literature on anatomy etc. are given on p. 239.

The Winteraceae of the Old World. I. Pseudowintera and Drimys — Morphology and taxonomy

Ano: 1977

URL: http://www.repository.naturalis.nl/record/525280

The primitive woody Angiosperm family Winteraceae is centred in the southwest Pacific, has an outpost in Madagascar (1 species), and a section of Drimys (4 species) in the New World. Pseudowintera is restricted to New Zealand, the Old World section Tasmannia of Drimys extends from the Philippines to Tasmania. Since A. C. Smith’s review of the family in 1943 about ten times as much material has become available and it appears that the taxonomy of the section Tasmannia is far more complicated than it seemed to be in 1943. This induced me to make a field study in New Guinea and to pay special attention to its morphology in the hope of finding additional criteria. On this basis the Australian species of Drimys could be better defined but the characters of the...

Ledermann’s and some other German localities in Papua New Guinea

Veldkamp, J.F.; Vink, W.; Frodin, D.G..

Collecting localities are of special interest to those who want to know the exact origin of the material under study: e.g. when citing types, designating neotypes, preparing distribution maps, planning expeditions, comparing species lists, or because of some historical interest. It is not always easy to gather these data, especially in the case of many former colonies where geographical names as used on collections have been changed (or may never have been recorded by the authorities and include on maps or in official gazetteers). As we have spent some time to gather the present information, we thought a wider audience might be interested. For a brief period, 1884 to 1921, the northern half of Papua New Guinea was a German colony, and the mainland portion...

The Hamameli(i)dae comprise, according to the new classification by Thorne, about one quarter of the genera to one third of the families of the Dicotyledonae. The symposium held at the University of Reading, U.K, 22-25 March 1988, highlighted some of the many questions concerning phylogeny and evolution in this group as a contribution to the insight in the main lines of dicotyledonous evolution. The symposium report contains a wealth of information on a wide variety of topics. The phylogenetic position of the Hamamelidae in a wider or narrower sense, or parts thereof, is subject of a number of papers. F. EHRENDORFER reviews the existing diverging interpretations and concludes that the Hamamelidae can be regarded as ancient and partly relictual survivors...

The Winteraceae pf the Old World. III. Notes on the ovary of Takhtajania

Ano: 1990

URL: http://www.repository.naturalis.nl/record/525453

Very recently Baranova & Leroy (Leroy, 1978) published a new genus Takhtajania to accomodate the aberrant Bubbia perrieri Capuron. The outstanding characters of this genus are the anomocytic stomatal apparatus (Baranova, 1972; Bongers, 1973) and the unilocular bicarpellate ovary (Leroy, 1977, 1978). During my work on the Winteraceae, I also studied the single specimen of Bubbia perrieri in existence. The late Capuron told me that he had tried to collect additional specimens but that he had not succeeded in doing so; according to him the type locality was completely deforested. In view of the scarcity of the material it was considered relevant to publish some additional notes without delay.

Hamamelidaceae

Evergreen (or deciduous) shrubs or trees. Buds perulate (or naked); innovations flush-wise. Leaves simple, spirally arranged (rarely opposite), usually penninerved, less often 3—5-plinerved, with entire, crenate-serrate or dentate margins, often slightly oblique at the base. Indument often stellate, tufted or lepidote. Stipules usually present, very small to large. Flowers free or connate, in heads, spikes or racemes, ♀, polygamous or unisexual and monoecious (rarely dioecious), usually actinomorphous, usually 4—5-merous, with alternate whorls of floral parts. Sepals usually small or lacking. Petals often linear or ligulate, often rolled in bud, sometimes lacking. Stamens free, often in two whorls, the inner ones staminodial; anthers almost always basifix;...

The Winteraceae of the Old World. VI. New taxa and combinations in New Caledonian Zygogynum

Ano: 1955

Quite a number of identifications of New Caldeonian Winteraceae have been distributed to herbaria and to collectors. A number of the new taxa and new combinations involved have already been published in Blumea 31 (1985) 52-54. Awaiting the forthcoming revision it seems pertinent to complete this list as far as New Caledonian taxa are concerned.

Revision of Magodendron (Sapotaceae) with observations on floral development and morphology

Ano: 1970

URL: http://www.repository.naturalis.nl/record/524564

The genus Magodendron Vink is revised. A second species, M. mennyae, is described. In the developing flower the staminodes are initiated when the stamens are already distinctly differentiated into filament and anther. The probability of movements of the staminodes during anthesis is discussed. In the youngest stages observed the pistil is a single, apically open locule; the sept primordia on its wall are free from the pistil base. The septs grow towards the centre of the pistil. The concrescence of the septs is imperfect, resulting in open connections between the ovarial locules and towards the stigma.

Recent collections of Exospermum completed the break-down of the generic differences between Bubbia and Zygogynum. The oldest name for the resulting enlarged genus is, unfortunately, Zygogynum. The characters, relating to these reductions, are reviewed. One new name and 30 new combinations are made; two new species and one new subspecies are described.

Steenis, C.G.G.J. van; Vink, W.; Bakhuizen van den Brink Jr., R.C.; Jacobs, M..

An account of phytochemical substance has been provided by Wiesner’s Rohstoffe des Pflanzenreichs, arranged by products, another account has been given by Karrer, compounds of established constitution arranged according to a chemical system. Though useful, none of these works, including also those of Czapek and Wehmer, aims, however, to use phytochemistry as an auxiliary branch of plant taxonomy. It does seem necessary here to stress in a concise way the importance of the subject for taxonomy. All of us have used some coarse phytochemical characters, looked at characteristic glands and crystals, observed and used colours of dried leaves, tasted plants for bitter substances, sniffed at aromatic oils, and other secondary compounds. The use of these...

The Winteraceae of the Old World. VII. Zygogynum in the Solomon Islands (incl. Bougainville)

Ano: 1963

URL: http://www.repository.naturalis.nl/record/525545

A review of the character distribution in the Zygogynum representatives from the Solomon Islands (and Bougainville) shows a rather wide variability in ranges of numbers and sizes, often with distinct differences between islands or altitudinal ranges. However, the morphology is rather uniform. The four species recognised by A.C. Smith had to be synonymised, but a new taxon deserved recognition. The name Bubbia is explained.
