Abstract: | Thirty-two differential characters are numerically analysed for the six existing taxa of the genus Vella L. The closely related monotypic genus Boleum Desv. is also included for comparison. Most of the characters used are morphological, but cariological, ecological and biogeographical aspects have also been studied. The results indicate that four distinct species, one ( V. pseudocytisus L.) with three sub-species, should be distinguished. The new combination V. anremerica (Lit. et Maire) Gómez-Campo (basionym: V. pseudocytisus L. subsp. anremerica Lit. et Maire) and the new name V. pseudocytisus L. subsp. paui Gómez-Campo for V. pseudocytisus L. var. glabrescens Willk., nornen nudum are presented. A key is given to aid identification of these taxa. Their conservation status is also discussed. |
