Ranunculus carinthiacus HoppeCarinthian Buttercup, DE: Krntner HahnefuSlo.: koroka zlaticaDat.: June 6. 2015Lat.: 46.43718 Long.: 13.63990Code: Bot_884/2015_IMG8149Habitat: Mountain pasture, grassland among outcropped rocks; almost flat terrain, Calcareous ground, open place, full sun, exposed to direct rain, elevation 1.860 m (6.100 feet), average precipitations ~ 3.000 mm/year, average temperature 1 - 3 deg C, alpine phytogeographical region. Substratum: soil.Place: Mt. Mangart flats, next to Mt. Mangart Alpine tool road, next to the access road to mountain cottage 'Koa na Mangartu', East Julian Alps, Posoje, Slovenia EC Comments: Ranunculus carinthiacus is named after Carinthia, which was a name of a historic country, which territory partly corresponded to the northeast part of present Slovenia. Yet, it is not an endemic plant bound to this territory, because it grows in most of the Southeast Alps as well as in some parts of the West Alps, in Pyrenees and also on Balkan mountains. In Switzerland and in Austria it is considered as a rather rare plant, while on grassland of Mangart's flatsit is probably the dominant blooming plant in June. Its golden yellow flowers can be seen almost everywhere. The plant is poisonous.To separate it from more common, somewhat taller but generally very similar Ranunculus montanus one has to be careful regarding stalk leaves. Ranunculus montanus has broader leaflets of stalk leaves (they are less than 7 times longer than broad, while with Ranunculus carinthiacus they are even narrower). Another important trait is the surface of their ground leaves. With Ranunculus montanus it is hairy, while with Ranunculus carinthiacus they are glabrous. Ref.:(1) A.

Ranunculus chius DC, syn.: Ranunculus incrassatus Guss.Eastern Buttercup, DE: Chios HahnenfuSlo.: napihnjena zlaticaHabitat.Dat.: April 24. 2015Lat.: 45.06876 Long.: 14.44834Code: Bot_0867/2015_DSC5895Picture file names: from Ranunculus chius_raw_1 to Ranunculus chius_raw_5.Habitat: a small, newly established figs trees plantation; flat terrain, sunny and dry place; calcareous, skeletal ground, exposed to direct rain, elevation 80 m (260 feet), average precipitations 1.000-1.200 mm/year, average temperature 13 - 15 deg C, Sub-Mediterranean phytogeographical region.Substratum: Karst soil.Place: Fields on the right side of the road from Milohni village to Vela Jana harbor, west Krk island, Kvarner bay, Adriatic Sea, Croatia EC.Comment: Ranunculus chius, named after Greek island Chios, is an inconspicuous, rather small, annual buttercup plant seldom encountered. This is probably due to its mall, inconspicuous flowers, its hiddenness among other greenery in grassland and also because it is nowhere a common plant. It is a species of a Mediterranean-eastern European distribution with a rather sparse and erratic distribution. It usually grows in wet meadows and in temporary pools, from sea level to lower montane elevations. Habitat of this find is in a sharp contradiction to this. The plant is toxic due to the content of anemonine.There are many buttercups described, but Ranunculus chius is relatively easy to recognize. Not by its flowers, which may have from 3 to 5 developed petals, but by its swollen fruiting pedicels thickened toward the apex (see Fig. 1b). Its achenes are also characteristic. They are dark brown when fully developed and are densely covered by short prickles. One can see these prickles starting to develop on Fig. 2b, which shows young, not yet ripe achenes.Ref.:(1) A.
