Small-flowered bittercress, Cardamine parviflora L. (Brassicaceae), a new species of the Croatian flora

Cardamine parviflora L. was discovered in April 2014 during the study of vascular flora and habitats in the area of Slatina (Slavonia region). It was found in a flooded forest of narrow-leaved ash, in the vicinity of the villages Medinci and Novi Senkovac. The species here grows in wet soil but partially submerged populations were also observed. It presents a new species of the Croatian flora and expands the floristic inventory of Slatina and its surroundings. Other valuable taxa have also been recorded in the area, such as Carex riparia Curtis and Ophioglossum vulgatum L

Rijetko bilježena i kritično ugrožena vrsta Scirpus supinus L. u Hrvatskoj – novi nalazi s područja grada Slatine

The paper presents two new localities for the critically endangered Scirpus supinus L. (Cyperaceae) which was recorded during botanical surveys in surroundings of the City of Slatina in Slavonia. The species is associated with the alliance Nanocyperion and was found in damp microdepressions on agricultural land. Previously, only two localities had been known for S. supinus in Croatia, both of which are herbarium vouchers dating back to the mid-twentieth century and should be confirmed at those areas during future research.Rad donosi dva nova nalazišta za kritično ugroženu vrstu Scirpus supinus L. (Cyperacae) zabilježenu tijekom botaničkih istraživanja u okolici grada Slatine u Slavoniji. Vrsta se javlja unutar sveze Nanocyperion u vlažnim mikrodepresijama među obradivim površinama. Dosad su za vrstu S. supinus bila poznata samo dva lokaliteta u Hrvatskoj, oba kao herbarijski primjerci iz sredine prošloga stoljeća koje u budućim istraživanjima valja potvrditi na terenu
