The article discusses the categories of botanical scarcity which are rare, threatened, and endangered. Topics include the definition of rarity, the variation in the relationship between specific environments and species, and the qualitative factors that contribute to endangerment. It also examines the threats to the endangered or threatened status of a species such as competition, habitat changes, and the invasion of other species.

    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...
