摘要:

SummaryComputer programs are being developed and tested for editing dichotomous keys, particularly to meet the challenges offered by the Flora North America Project. An elementary editing system is available for revising previously prepared keys; the new versions are then printed in conventional indented form. An advanced editing system currently being tested improves the efficiency of the process and offers a choice of output formats. For this latter approach the data are stored in three files: a taxon list, a descriptor list, and a numeric representation of the key. A variety of editing procedures are possible, including additions and deletions of taxa, changes in descriptors, and even translation of the key from one language to another. The system is designed for compatibility with the first author's experimental programs for constructing keys and making direct identifications.

摘要:

SummaryA very particular flavonoid content, compared with the classical systematic data, allows to attribute a relatively isolated place in the order of the Rosales, to the family of the Bruniaceae, chemically studied for the first time.

摘要:

SummaryThe results of a chemical study concerning 7 species of Cunoniaceae show the heterogeneity of the family. The classical systematic data and chemical features suggest that the Cunoniaceae are closely related to the Saxifragaceae and that the former are austral vicariants of the latter. The relationships ofBaueraandEucryphiato Cunoniaceae is confirmed.

摘要:

SummaryDetails are given of the publication of Dennstedt'sSchlüsselgiving “Linnaean” names for the taxa described in Rheede tot Draakestein'sHortus indicus malabaricus.Dennstedt's work was published in two editions: in the Fortsetzung des Allgemeinen Teutschen Garten‐Magazins (Oct. and Nov.‐Dec. 1818) and as a separate with independent pagination (Oct. 1818). The nomenclatural evaluation of the new taxa is discussed and lists are given of validly published new combinations and of nomina nuda.

摘要:

SummaryIssue is taken with the proposal by McVaugh and Bullock to deprive arbitrarily certain substitute names of their status of valid publication. A proposal is made to correct misuse of the word “orthographic” in the Code.

摘要:

SummaryA ‘new taxon’ is not, or only rarely, a newly evolved taxon whilst a new species is new only in a nomenclatural sense or, as it was phrased in earlier generations “new to science”. The indication“nom. nov.”must be regarded as a technical term indicating a new name replacing an old one which is illegitimate under the Code.

摘要:

SummaryThe possibilities to typify the several hundred species in Linnaeus'sSystema naturaeed. 10 (1759) which do not figure in theSpecies plantarum(1753) are analyzed. Many of these species can be typified because they were published by Linnaeus between 1755 and 1759 in other publications, others on the basis of the subsequent treatment in the second edition of Species plantarum (1762–1763). A small number of species (29) are difficult to typify and require further investigation. Some may have to be treated asnomina dubiaor provided with a neotype.

摘要:

SummaryGaterau's publicationDescription des plantes qui croissent aux environs de Montauban …of 1789 contains 73 names by Gaterau of which 50 are not listed in theIndex kewensis.These names are all validly published but illegitimate because proposed as new names for earlier legitimate ones which were considered inappropriate. The fifty names not taken up by theIndex kewensisare here listed in accordance with their nomenclatural status (later homonyms, earlier homonyms, earlier publications of the same name and names totally absent from theIndex kewensis).

摘要:

SummaryAn examination of the type specimens of two of the most widely distributed species ofAcrochaetiumgrowing inLiagoraclarifies the status ofA. liagoraeBørgesen (which includesA. collinsianum) and A.barbadense(Vickers) Børgesen (including A.liagoraeof Hamel and A.vanbosseaePapenfuss). Remarks are also made on A.laxumwhich has been confused with A.liagorae.
