Developing standardised classification of post-fire responses is essential for globally consistent comparisons of woody vegetation communities. Existing classification systems are based on responses of species growing in fire-prone environments. To accommodate species that occur in rarely burnt environments, we have suggested some important points of clarification to earlier schemes categorizing post-fire responses. We have illustrated this approach using several Australasian conifer species as examples of pyrophobic species. In particular, we suggest using the term “obligate seeder” for the general category of plants that rely on seed to reproduce, and qualifying this to “post-fire obligate seeder” for the narrower category of species with populations that recover from canopy fire only by seeding; the species are typically fire-cued, with large aerial or soil seed banks that germinate profusely following a fire, and grow and reproduce rapidly in order to renew the seed bank before the next fire.

Table Method

The vegetation of the Jack Scott Nature Reserve in the Central Bankenveld Veld Type is classified chiefly by the Braun-Blanquet Table Method. Habitat features, physiognomy, total floristic composition, differentiating species, woody plants and prominent grasses and forbs are presented for each community. Characterizing habitat features, in order of importance for the communities, are: exposure, soil texture, geology, slope, aspect, degree of rockiness and previous ploughing. The classification correlates well with the major physiographic and climatic variation in the Reserve and generally does not cut across main physiognomic types. The communities are potentially homogeneous management units.

Document Processing Systems (DPSs) support office workers to manage information. Document classification is a major function of DPSs. By analyzing a document’s layout and conceptual structures, we present in this paper a sample-based approach to document classification. We represent a document’s layout structure by an ordered labeled tree through a procedure known as nested segmentation and represent the document’s conceptual structure by a set of attribute type pairs. The layout similarities between the document to be classified and sample documents are determined by a previously developed approximate tree matching toolkit. The conceptual similarities between the documents are determined by analyzing their contents and by calculating the degree of conceptual closeness. The document type is identified by computing both the layout and conceptual similarities between the document to be classified and the samples in the document sample base. Some experimental results are presented, which demonstrate the effectiveness of the proposed techniques.

Español. Después de analizar las alternativas de clasificación del complejo Carthamus-Carduncellus que son compatibles con los resultados de los análisis moleculares, se propone volver a la clasificación en dos géneros de Hanelt (1963) modificada por la inclusión de Carthamus sect. Thamnacanthus (DC.) Hanelt en Carduncellus Adans.; se incluye Femeniasia Susanna, no estudiada por Hanelt, en Carduncellus. Se hacen las nuevas combinaciones Carduncellus rhiphaeus (Font Quer & Pau) G. López, Carduncellus balearicus (J. J. Rodr.) G. López, Carduncellus sect. Thamnacanthus (DC.) G. López y C. hispanicus subsp. intercedens (Degen & Hervier) G. López. Se describe la nueva serie Carduncellus ser. Fruticosi G. López, y las variedades C. monspelliensium var. almeriensis G. López & var. valentinus G. López. Carthamus L., tal como aquí se delimita, esta formado únicamente por plantas anuales que tienen las cipselas externas epaposas (muy raramente con vilano), y el resto con un vilano persistente formado por cerdas anchas, paleáceas, linear-lanceoladas o espatuladas. Carduncellus Adans., por plantas perennes, herbáceas o leñosas en las que todas las cipselas tienen vilano (muy raramente pueden ser epaposas), siendo el vilano persistente o frecuentemente caduco, formado por cerdas estrechamente lineares. Carthamus es del Mediterráneo oriental y O. de Asia , y Carduncellus Adans. está centrado biogeográficamente en el Mediterráneo occidental.English.  Different alternative classifications congruent with the molecular analyses of the complex Carthamus-Carduncellus are discussed. It is proposed to return to the traditional Hanel (1963) classification, but with Carthamus sect. Thamnacanthus (DC.) Hanelt included in Carduncellus Adans.; the genus Femeniasia Susanna, not studied by Hanelt, is also included in Carduncellus. The new combinations Carduncellus rhiphaeus (Font Quer & Pau) G. López, Carduncellus balearicus (J. J. Rodr.) G. López, Carduncellus sect. Thamnacanthus (DC.) G. López and C. hispanicus subsp. intercedens (Degen & Hervier) G. López are proposed. The new serie Carduncellusser. Fruticosi G. López, and the varieties C. monspelliensium var. almeriensis G. López & var. valentinus G. López are described. Carthamus L., as delimited here, include only annual plants having outer cypselas without pappus (rarely all epappose) and the rest with a persistent pappus of wide, paleaceous, linear-lanceolate o spatulate bristles. Carduncellus Adans., on the other hand, include perennial herbaceous or woody plants having all the cypselas with pappus (very rarely epappose), the pappus, persistent or deciduous, of narrow linear bristles. Carthamus L. is of East Mediterranean and West Asia origin, and Carduncellus Adans. has its center in the western Mediterranean region.
