Floristic plant geography: the classification of floristic areas and floristic elements
A major objective is the identification and classification of floristic areas and floristic elements. The spatial scale of plant geography can be divided into three segments: microregional, mesoregional and macroregional. Historical biogeograhies
are based on the assumption that most species are relatively old. It is likely, however, that major extinctions and speciation events have reshaped the world's flora. Floristic plant geography, with its detailed evaluation of modern patterns and whole floras
A study on the spatial differentiation and the division of floristic phytogeography of Xizang (Tibet)
An approach to the floristic phytogeographical differentiation of the study area has been made with the help of a quantitative floristic method. Main geographical elements of the flora, the spectra of floristic elements and its regional
differentiation, floristic boundaries and division of Xizang are discussed in the present paper.

The AA. first explored how the floristic composition of the plant communities is related to the different environmental gradients. They discuss the environmental variables that they found to be highly correlated with the floristic composition

The summary of the geomorphological, pedological and climatic conditions in the vicinity of Nyiregyhaza are outlined. A floristic geographical description is followed by the characterization of natural vegetation associations. (DLO).
A floristic quadrat study of sparsely wooded plains on western Melville Island was conducted and used to define and describe floristic and structural vegetation types and identify their associated environmental correlates. The results were compared
The ecosystematical evaluation of different units of landscapes and the distributional pattern of floristical groups and different ecosystems is represented in Ecological Maps with vegetation units. Species diversity, the abundance of species
and the occurence of autochtonous and allochtonous ecosystems indicate a precipitation gradient leading from SE to NW, which shows a different effectiveness regarding the conditions of topography, soils and geomorphology. The floristical research was supported

in the south. In order to compare the transect with the overall Belgian situation a reference list of the Belgian flora, the standard list, has been made. The floristical evaluation method of MENNEMA has been applied to the species lists. It appears
that the afforested heath landscape has significantly higher scores for the floristical value and the value of the vegetation. These values are highly correlated with the species-number per km (r>0,90). Because of this correlation, an alternative approach is proposed.

Biological and recreational values of 17 Brussels'parks have been estimated using customary criteria. The principal criteria are: the diversity of vegetation forms, the floristic diversity, the scarceness, the degrees of hemerobie
