Abstract: This paper presents data on the admissions process in a Regional neuro-rehabilitation centre, using the framework proposed in Thomas Scheff's classic paper on typification in the diagnostic process as a starting point for analysis. We argue that typification is a more complex and diffuse process than Scheff's ‘diagnostic stereotype’ concept suggests, and that this may be linked to the particular work imperatives and relevancies that are important in this setting.

Abstract: The species group previously known as Hebe ‘Paniculatae’ is segregated as a new genus, Heliohebe. The new genus is characterised by a number of unique synapomorphies, and does not share apomorphic character states with Hebe, Parahebe, Derwentia, or Chionohebe. It appears to have arisen early in the radiation of the New Zealand Veroniceae. Five species are recognised: H. hulkeana with two subspecies, H. lavaudiana, H. pentasepala, H. raoulii with two subspecies, and H. acuta. H. acuta is a new species and H. pentasepala was formerly treated at varietal rank under Hebe raoulii. H. acuta is quite similar to H. raoulii, but has smaller, more intensely coloured flowers, and the anterior calyx lobes are free. It grows sympatrically with H. hulkeana subsp. hulkeana, H. pentasepala, and H. raoulii subsp. raoulii. Keys, synonymy and typification, descriptions of all taxa, distribution maps, and a cladistic analysis of Heliohebe are presented.

Abstract: Forty mosses are recorded for Pakistan, of which six appear to be new records for that country. Timmiella subintegra Dix. is reduced to synonymy under T. barbuloides (Brid.) Moenk., and there are notes on the typification of Pilotrichum pluvinii Brid. (Cryptoleptodon pluvinii (Brid.) Broth.).

Abstract: Nomenclature, typification, generalised distribution, chromosome number, description and taxonomic notes are given for each of 15 species and subspecies recognised withinLuzula sect.Luzula in Europe. Attention is paid to possible ways of evolution in the section in Europe. Critical cases are annotated without formal classification. Appendices with an identification key and a selection of herbarium specimens studied are provided.

Abstract: The neotropical genus Chionolaena is accepted as including the species of Leucopholis, which has been considered a separate genus by several authors because of its few-flowered capitula. Chionolaena consists of small, more or less woody shrubs with a discontinuous distribution: central Mexico, northern Colombia, and southern Brazil, with disjunct populations in Central America (Costa Rica) and northern Amazonia (southern Venezuela). The most closely related genus is Gnaphaliothamnus from Mexico and Guatemala. Seventeen species of Chionolaena are recognized, one of which, C. mexicana, is described for the first time. Three new combinations are made: Chionolaena capitata, C. chrysocoma, and C. seemannii. Descriptions, typification, synonymy, distribution maps, illustrations, indices, and a key to all taxa are presented (...)

Abstract: The typification of Pleurosigma obscurum W. Smith is discussed with reference to material collected by W. Smith. The placing of the species in the genus Gyrosigma in recent publications is incorrect. All intact cells of this organism were collected in non-marine samples. Claims in the literature for a marine-brackish ecology of this organism may be due to the fact that marine-brackish environments harbour several species that cannot be separated from P. obscurum using traditional species criteria.

Abstract: A lectotype for Xylaria digitata ss. Nitschke & al. is chosen and a new species, X. friesii based on X. digitata sensu Lundell & Nannfeldt is described. Xylaria scotica is placed into the synonymy of X. guepini and X. torulosa is considered a dubious taxon not related to X. digitata. The relationship between X. acuta and X. digitata is discussed and likewise between X. bulbosa, X. friesii, and X. guepini.

Abstract: Lectotypes are proposed for Linnaeus's names for European species belonging to Sedum subgen. Sedum, i.e. S. acre L., S. album L., S. annuum L., S. atratum L., S. caeruleum L., S. cepaea L., S. dasyphyllum L., S. hispanicum L., S. reflexum L., S. rubens L., S. rupestre L., S. stellatum L., S. villosum L., and for Tillaea rubra L., which is the basionym of S. rubrum (L.) Thell. For S. sexangulare L. a neotype is proposed which has been chosen from the material in the Linnaean herbarium in Stockholm. The typification of these names in all cases serves to maintain general usage. In particular, the typification of S. sexangulare, S. rubens, S. rupestre, and Tillaea rubra helps to settle disputes about the application of these names, guarantees their unambiguous use, and thus serves stability of nomenclature.

Abstract: Haworthia Duval (Asphodelaceae: Alooideae) is a taxonomically difficult genus under which c. 400 names have been published, most of them (excepting the most recent) not yet typified. Scott in his recent monograph of Haworthia attempted typification on a large scale, but of his four different ways of citing or indicating type specimens, two involving more than 50 % of the accepted names do not constitute effective typification. The importance of making new typifications explicit in taxonomic studies is discussed.

Silva, Rozeira etFontes 1952,Genisto-Vaccinion Br.-Bl. 1926,Ulicetalia minoris Quantin 1935 andCalluno-Ulicetea Br.-Bl. etR. Tx. 1943

Abstract: Monasterio-Huelin, E. & Castroviejo, S.: Typification of the names of Iberian Rubus species described by Sampaio. Taxon 42: 601-608. 1993. ISSN 0040-0262. Lectotypes are designated for the 13 binomials validly published by Sampaio in Rubus, based on the study of the original material in Sampaio's herbarium in Oporto (PO) and of duplicates present in Madrid (MA). Of the 13 named species of Rubus described by Sampaio, 5 (R. sampaioanus, R. vagabundus, R. peratticus, R. henriquesii and R. brigantinus) are considered autonomous (regional), while the rest appear to be merely local species.

Abstract: Le Musée botanique cantonal à Lausanne (LAU) possède un important herbier de ronces à l’origine duquel se trouve la collection de Philippe-Jacques Müller. Ce botaniste alsacien décrivit, au XIXe siècle, maintes espèces nouvelles (MÜLLER 1858, 1859). Selon FAVRAT (1890), P. J. Müller, né le 19 janvier 1832 à Wissembourg (Département du Bas-Rhin) s'intéressa probablement aux ronces sur le conseil du botaniste allemand voisin Friedrich-Wilhelm Schultz. Plusieurs échantillons de ronces françaises lui ont été communiqués par Louis-Victor Lefèvre, un instituteur résidant dans le département de l’Oise. Müller l’associa alors aux déterminations des espèces nouvelles: on trouve ainsi, par exemple, Rubus acicularis L.V.L. et P.J.M. ou Rubus acutatus P.J.M. et L.V.L. Après la guerre franco-allemande, en 1872, Müller opta pour la nationalité française et quitta l’Alsace. Il vint alors s’installer en Suisse, à Nyon, où, ayant abandonné toutes ses études, il vécut très retiré. Il mourut le 13 mai 1889 et ses collections de plantes furent données par ses héritiers au Musée botanique cantonal à Lausanne. En 1902, Henri Sudre, professeur à l’école normale d’Albi puis à celle de Toulouse, entreprit de classer et même de compléter la collection. Après l’avoir parcourue une première fois, il écrivait au professeur Ernest Wilczek, conservateur du Musée de botanique: “[...] Je vous offre en échange d’introduire dans ladite collection des spécimens destinés soit à la compléter, soit à remplacer les échantillons qui pourraient être incomplets ou mal conservés”. Le travail fut gigantesque, et Sudre, en renvoyant les 5 caisses qui contenaient la collection triée, écrivait encore: “[...] Aujourd’hui que le travail est fini, je ne regrette pas de l’avoir entrepris; mais si c’était à recommencer j’y renoncerais. Il y avait dans cette collection le plus complet désordre et la plupart des spécimens étaient mal ou non déterminés. Müller lui-même n’avait pas pris la peine, dans beaucoup de cas, de faire figurer sur ses étiquettes le nom qu’il avait publié, nom souvent très différent du primitif et provisoire qui accompagne plusieurs de ces espèces. [...]”. Cette révision, et celle d’autres grandes collections européennes achevées, SUDRE publia de 1908-1913 une grosse monographie, accompagnée de 205 planches, qui sert de base de classement à la collection du Musée.

Abstract: A new, phyllidiate, white-medulla species with yellow pseudocyphellae and a green photobiont, Pseudocyphellaria kalbii D.J.Galloway, is described from Brazilian collections, and typification and notes on P. aurora (De Not.) Vainio are presented.

Abstract: A taxonomic survey is given of eight species of the South and Central European group within theTaraxacum sect.Palustria. Descriptions and figures characterise four taxa treated in more detail (T. abrotanum andT. insolitum of them are described as new to science from Greece); all the eight members of the group are given synonymy and typification.
