Abstract:

Chamaecytisus erythropetalus Yıldırım has been found in Western Anatolia (Türkiye), in İzmir province and it is described as a new species for science in here. Although C. erythropetalus resembles to C. spinescens in habit due to its remnant stems from previous years, it can be easily distinguished from C. spinescens with its erect a single or several stemmed habit; tips of branches ending with a flower or flowers group; never thorny branches tips; both lower and upper surfaces of leaves cover with densely appressed hairs; and the leaves noticeably curled inwards. On the other hand, although it shows some morphological similarities to C. gueneri, it distinguished with a single or several stemmed at the base, the formation of dried permanent branches from old years on the stems, and the stems shows dens branching; the leaflets are quite narrow and curly like a boat shape, acute to acuminate at the tips, and completely sessile; the flowering branches are generally single-flowered or in groups of 2-3(-4) flowers. In this study, a detailed description of the new species, morphological comparisons with close species and field photographs are given.
