Abstract

The flowering of Rubio longifoliae-Quercetum rotundifoliae fraxinetosum orni Costa. Peris & Figuerola. The flowering of Rubio longifoliae-Quercetum rotundifoliae fraxinetosum orni Costa, Peris & Figuerola 1982 is studied during the dry year 1983 in the "carrascal" maquis-wood of the Barranco Real (Valencia, Spain). The formation is characterised by high frequencies of multiple flowerings - more of one flowering along the year. The "optimum" flowering - highest frequency in a taxon - is pertaining to the spring, while the "suboptimum" flowering - low frequencies in a taxon - is autumnal and it is related with the season whose pluviometric values are highest.
