Reseda inodora Rchb., a new species of the Croatian flora

A population of Reseda inodora Rchb. was found in Bansko brdo (Baranya, Croatia), in April 2007. This Pontic-Pannonian species was not previously included in the recent Croatian botanical database. The chorology of R. inodora seems to be important, because this finding is on the western border of the species area. Considering the low number of individuals and small extension of occurrence, R. inodora should be treated as a critically endangered species in Croatia. A phytocoenological relevé taken on its habitat, a short morphological description of R. inodora and a new key of Reseda L. species of Croatia are presented

Herbaceous periwinkle, Vinca herbacea Waldst. et Kit. 1799 (Apocynaceae), a new species of the Croatian flora

Populations of herbaceous periwinkle, Vinca herbacea Waldst. et Kit., were found on April 2007 on Bansko Hill (Baranja, Croatia), which lies on the south-western edge of the range of this Pontic-Pannonian species. Since V. herbacea was included neither in the handbooks for plant identification nor in the current Croatian Flora Database, a new key for the determination of Vinca L. species of Croatia is presented herein. The herbaceous periwinkle should be treated as a critically endangered (CR) species in Croatia, considering the low number of individuals and the small extent of its occurrence in extremely rare habitats at the margin of its distribution. New recordings of some very rare or »data deficient« (DD) taxa of Croatia are also presented here: Scorzonera hispanica L. and Inula germanica L
