Helleborus multifidus ssp. istriacus Vis. (Schiffner) Merxm. & Podl., syn.: Helleborus istriacus (Schiffn.) Borbas, Helleborus odorus Waldst. et Kit. var. istriacus Schiffn., Helleborus viridis subsp. istriacus (Schiffn.) Cristof. & ZanottiLacy Hellebore (?), DE: Istrische Vielspaltige Nieswurz, Istrische NieswurzSlo.: istrski deljenolistni teloh, istrski telohDat.: Apr. 23. 2015Lat.: 45.08763 Long.: 14.45765Code: Bot_0866/2015_DSC5865Habitat: grassland, edge of a pasture next to mixed hardwood forest; locally flat terrain; calcareous, skeletal ground; dry, partly shady, rather open place; exposed to direct rain; elevation 130 m (430 feet); average precipitations ~ 1.000 mm/year, average temperature 13-15 deg C, Sub-Mediterranean phytogeographical region. Substratum: soil.Place: West part of the island Krk, about 500 m north of village Milohnii; Kvarner bay archipelago, Adriatic Sea, Croatia EC.Comment: Taxonomy of the genus Helleborus is 'complex'. Several interpretations exist. The two main reasons are: very frequent occurrences of intermediated forms between species and many and frequent hybrids. Helleborus multifidus ssp. istriacus had been for decades considered as a subspecies of similar Helleborus odorus. Once it was also considered a subspecies of Helleborus viridis. Other authors consider it on species level as Helleborus istriacus. Following the key in Rottersteiner (2014), Ref.: 1 the photographed plants belong to Helleborus multifidus ssp. istriacus due to its palmatelly divided ground leaves with many leaflets (10-15), which are deeply incised, some nearly to the bottom of the leaf and some to about one half of the leaflet length. The leaf edge is finely and sharply serrated (toothed with teeth directed forward). The leaflets should be wider than 15 mm in contrast to very similar subspecies Helleborus multifidus ssp. multifidus, which is supposed to have narrower leaflets. To distinguish both is many times difficult. This is particularly true (including Helleborus odorus) in early spring in March when plants bloom. The ground leaves are not yet developed at that time and the flower stalks and flowers are very variable in all of them. These pictures show plants already forming seeds.The Helleborus multifidus ssp. istriacus is endemic to peninsula Istria and surrounding regions including Kvarner archipelago islands. Apart of this it can be found also in Croatia's central-western part. It grows also in southwest Slovenia, as well as in most northwest part of Italy near the town Trieste.Ref.:(1) W.K.

Ranunculus trichophyllus s.str. Chaix, syn.: Batrachium trichophyllum (Chaix) F. W. Schultz, Ranunculus divaricatus SchrankFamily: RanunculaceaeSubgenus: BatrachiumEN: Threadleaf Crowfoot, Thread-leaved Water Crowfoot, DE: Gewhnlicher Harrblat WasserhahnenfuSlo.: lasastolistna vodna zlaticaDat.: April 24. 2018Lat.: 45.09614 Long.: 14.49151 (WGS84)Code: Bot_1126/2018_DSC2186Habitat: Water pond in the midst of forest; flat terrain; calcareous ground; partly sunny;elevation 72 m (235 feet); average precipitations about 1.000 mm/year, average temperature 13-14 deg C, Sub-Mediterranean phytogeographical region. Substratum: soil.Place: West island Krk, Adriatic Sea, between villages Poljica and Turi, Kvarner bay, Croatia EC. Comment: The number of species in the genus Ranunculus - buttercups - is very large (about 600). Vast majority of them are terrestrial plants. Several are well known and common inhabitants of meadows. Yet, a small group of them (subgenus Batrachium) is living in still or slowly running waters. They are all relatively rare because their habitats are quickly disappearing because of human greed for useful land. These plants are all very variable and change their habit greatly depending on growth conditions - from floods to almost dry mud. Hence, their determination is often difficult. This find seems relatively a simple case in this respect. Plants' robust habit (from 0.5 to 3 m long stems up to 5 mm in diameter), small flowers (max 12 mm in diameter; that is significantly less than with most probable alternatives Ranunculus peltatus or Ranunculus aquatilis), petals, which are relatively narrow and do not overlap, roundish receptacle (the part of the peduncle where the flowers are born), sickle shaped nectary groves, absence of leaves floating on water surface, soft underwater leaves (they stick together and form a 'brush' when taken out of water) and the fact that floating stems are not rooting at the nodes or eventually only weakly and near their base, all this speaks in favor of Ranunculus trichophyllus.Ref.:(1) M.A. Fischer, W.
