The genus Helianthemum Miller, includes 12 annual or perennial species in the Flora of Turkey, 4 of which are endemic. In this study, macro and micromorphological, anatomical and palynological characteristics of the endemic Helianthemum nummularium (L.) Miller subsp. lycaonicum Coode&Cullen are studied. This species is grown on steppe, chalky and l...

In this study, the chromosome number and detailed morphometric properties of six endemic taxa belonging to five dicot families which grow naturally in Turkey were examined. The somatic chromosome number and karyotype formula of the taxa of Asteraceae family were determined to be 2n=18 and 8m+1sm in Tanacetum argenteum ssp. argenteum and 2n=18 and 7...

Camptopoeum (Camptopoeum) baldocki spec. nov., a new European panurgine bee species is described and diagnosed. It is currently known only from saltmarshes along the southern coast of the central and eastern Algarve, Portugal. Observations and analysis of scopal pollen loads suggest narrow oligolecty on the similarly halophilous Frankenia laevis (F...

Approximately 50 species of trees, shrubs and grasses common in Portugal were evaluated in relation to the emission of volatile organic compounds to the atmosphere. From the emission measurements and the spatial distribution of vegetation it is possible to conclude that only a few species including the maritime pine, the eucalyptus, the cork oak an...

... Corral et al. (1989) analyzed the seed morphology and histology of four Cistus species from Spain and stated that SEM observations show very clear differences among the patterns of their species. The rare two endemic Helianthemum species distributed in Turkey were studied and and results showed that seed characteristics clearly have taxonomic relevance (Yeşilyurt et al. 2015). ...
