New floristic and syntaxonomic data from rice fields in Bulgaria

Abstract

The present work is a floristic and phytocoenological study of rice fields in the Thracian Lowland, South Central Bulgaria. Two species new to the Bulgarian alien flora were found as a result: Heteranthera reniformis (Pontederiaceae) and Rotala ramosior (Lythraceae). The class Oryzetea sativae is documented with phytocoenological relevés for the first time in Bulgaria
