The role of rock mining for maintaining Dauco carotae-Crepidetum rhoeadifoliae Hejný et Grüll in Hejný et al. 1979 — a new to Poland plant association
2013
AbstractThis work presents the Dauco carotae-Crepidetum rhoeadifoliae plant association, which is new to Poland. The association has been observed in industrial reclamation areas in the vicinity of carbonate mineral excavation sites in the central part of the Opole region. In the vast majority of cases, plots of this association developed in reclaimed areas. The majority of diagnostic species for the association was found within surveyed plots, including Verbascum thapsus, V. densiflorum and Bryum argenteum. Taxa characteristic of the alliance were also constantly present, i.e. Daucus carota, Melilotus alba, M. officinalis, Echium vulgare and Erysimum hieracifolium. This association belongs…
Taxonomic and nomenclatural novelties concerning the Valencian flora (eastern Spain)
2008
Como paso previo a la publicación de la cuarta edición del Manual para la determinación de la flora valenciana, que se encuentra en fase de edición, en la presente contribución se discute la identidad y valor taxonómico de algunas plantas iberolevantinas presentes en la Comunidad Valenciana.

Korrelation zwischen Blattanatomie und Verbreitung der endemischen Echium ‐Arten Tenerifes (Kanarische Inseln)
2001
Correlation between leaf anatomy and distribution of the endemic Echium species in Tenerife (Canary Islands) In studying the leaf anatomy of autochthonous species in the genus Echium on Tenerife it is shown that the occurrence of particular anatomical and morphological structures correlate in a large degree with the climatic conditions in the single vegetation zones. This is clearly recognisable in the formation on the “indumentum” which coincides with other leaf-characteristics. In addition it could find out that the species with a wider distribution show a higher degree of intraspecific variability concerning the leaves mutually depending from the environmental factors.
