New data on the Middle Miocene flora of Northwest Bulgaria.

Two leaf imprints have been studied of the Middle Miocene flora from Ruzhintsi village, Northwest Bulgaria. One was determined as Macclintockia basinervis and the second as Tristaniopsis aff. laurina. New evidence has been obtained that Macclintockia is affiliated to the Myrtaceae family. In that context, the Australian species Melaleuca quinquenervia has been acknowledged as the nearest living relative to the first fossil species. In the course of determination of the second leaf imprint, a considerable morphological identity has been found with another representative of the family Myrtaceae, again from the Australian flora, namely, Tristaniopsis laurina. That recent species has been acknowledged as the nearest rlative to the fossil material, for the taxonomic determination of which the combination Tristaniopsis aff. laurina was applied.
