Iris adriatica (Iridaceae), a new species from Dalmatia (Croatia

Iris adraitica Trinajstić ex Mitić (Iridaceae), a new species from central Dalmatia (Croatia) was described and separated from the related species I. pseudopumila Tineo.Namely, recent authors have mostly agreed that the plants from Dalmatia are the same as those from Italy (Webb & Chater 1980, Mathew 1981, Mitić 2000). But, results of our comparative morphological research into the whole I.pumila complex, with other dwarf irises such as I.pumila L. and I. attica Boiss. et Heldr., showed up that irises from central Dalmatia are totaly different, morphologically less than half the size in most features than the typical Italian I. pseudopumila and has to be separated from I.pseudopumila and described as a new species, narrowly endemic to Croatia. The main characteristics of I. adriatica are: a dwarf stem (1-3 (5) cm long), gentle and narrow leaves longer than the stem, greenish spathes with wide scarious margins as long as or a bit longer than the hypanthial tube, solitary yellow or violet flowers overtopping the leaves, elliptical trigonous capsules (2-3 cm long), with elliptical dark brownish seeds and the chromosome number of 2n=16.
