Rosa pendulina L, syn.: Rosa alpina L.Alpine Rose, Drooping Rose, DE: Hngefrucht-Rose, Alpen Heckenrose, GebirgsroseSlo.: kimastoplodni ipek, alpski ipekDat.: July 1. 2018Lat.: 46.43792 Long.: 13.74716 (WGS84)Code: Bot_1144/2018_DSC04524Habitat: Moderately steep mountain slope, north aspect; light wood, Larix decidua, Pinus mugo, Fagus sylvatica dominant trees; among bushes; calcareous, stony ground; in half shade; elevation 1.555 m (5.100 feet); average precipitations ~ 3.000 mm/year, average temperature 2-4 deg C, alpine phytogeographical region. Substratum: soil.Place: North side of Vri pass; above the road in between last two, uppermost switchbacks, East Julian Alps, Posoje, Slovenia EC. Comment: Rosa pendulina is a widespread species of the genus in western Slovenia. However, it is not really a common plant. To encounter a bush in full bloom is always a delight. Its habitus is medium sized, rarely taller than 1.5 m. One can recognize it by its large and deep colored purple-red flowers with little white in the center, oddly pinnate leaves with 7 to 9 leaflets, which are usually almost glabrous and long, hastate sepals, which remain dry on the fruit. The shape of the fruit is also characteristic. Hips are flask-shaped and hanging. Young sprouts and branches are without prickles. The prickles on the stem and older branches are thin and straight, sometimes dense and sometimes scarce.Ref.:(1) M.A. Fischer, W. Adler, K.

Rosa glauca Pourr non Vill, syn.: Rosa rubrifolia Vill., Rosa ferruginea Gren.Glaucous Dog Rose, Red-leaved Rose, DE: Rotblttrige Rose, Rotblatt-RoseSlo.: rdeelistni ipekDate: June 25. 2008Lat.: 45.92286 Long.: 13.84985Code: Bot_277/2008_DSC0623Habitat: mountain dry grassland; calcareous ground; slightly inclined mountain slope, south aspect; warm, open and sunny place; elevation 1.010 m (3.300 feet); average precipitations 1.800-2.000 mm/year, average temperature 7-9 deg C, borderline between sub-Mediterranean and Dinaric phytogeographical region.Place: Mt. Mala Gora, 1.032 m (3.386 feet), aven ridge, central part of Mala Gora plateau; Vipava valley, Gorika, Slovenia EC.Comment: Wild dog roses (genus Rosa) are beautiful and well known plants. Their bushes, carrying numerous tender flowers of white, pink, different shades of red or yellow color, are wonderful decoration of stony meadows, wood edges as well as woods from lowland to high mountains. They are easily recognized on genus level. Unfortunately, the situation on species level is just the opposite frequently very difficult! There are many species in this genus, all are very variable and frequently form hybrids. 22 species are known in Slovenia hybrids, intermediate forms and cultivars, which escaped in the wild not counted. Many morphological traits must be considered in determination process. To reliably determine some of them one has to visit the plant two times, when in bloom and again when in fruit (two or three months later) because examination of hips is also necessary.Rosa glauca seems to be an exception in this respect. It can be quite readily recognized, not by some small morphological detail, but much more from general appearance. Mature bushes are stout, of dense growth and appear in the whole reddish, not only because of plenty of pink-purple flowers but also because of red branches and reddish 'leaves'. Actually, in spite of the plant's vernacular name in many languages, the leaves are reddish only when very young, then the leaflets become dark blue-green and only veins, leaflets borders and rachis (the main axis of the compound leaves) of the leaflets remain reddish. Anyway, the whole bushes have a characteristic, rather dark, reddish color, which can be noticed even from far.Ref.:(1) M.A. Fischer, W. Adler, K.

Rosa sempervirens L., syn.: Rosa serafinii subsp. scandens (Mill.) Arcang., Rosa candolleana Thory, Rosa atrovirens Viv EN: Rambling Rose, Evergreen Rose, DE: Immergrne RoseSlo.: vednozeleni ipekDat.: June 14. 2008Lat.: 45.81975 Long.: 13.61105Code: Bot_0271/2008_DSC9444Habitat: rocky bushland with grassland patches; moderately inclined hill slope, south aspect, calcareous, skeletal ground; open, warm and dry place; Karst region, elevation 200 m (660 feet); average precipitations 1.500-1.600 mm/year, average temperature 12-13 deg C, Sub-Medierranean phytogeographical region. Substratum: soil.Place: West of the village Sela na Krasu, next to the path to Slovenia-Italy border crossing Klarii, Brestovki dol, Primorska, Slovenia EC. Comment: Rosa sempervirens is a warmth loving rose and one of not so many growing in south Europe (more north the diversity of species of the genus Rosa is much more picturesque). It is most frequent in Mediterranean region. It touches the Alps only in a tiny, most south-west part of them where they themselves touch the Mediterranean Sea. Also in Slovenia it is limited to the warmest part of the country near Adriatic Sea shore. The pictures were taken in Brestaniki dol valley, which is the hottest spot in my country.The most characteristic traits of Rosa sempervirens are shiny, sharply toothed and quite leathery leaflets of the same green color on both sides and long styles, which are fused together into a column of comparable length to the inner stamens.Ref.:(1) A.

Rosa spinosissima L., syn.: Rosa pinpinellifolia L.Scotch Rose, Burnet Rose, DE: Bibernell-Rose, Reichstachelige RoseSlo.: bodiasti ipekDate: June 15. 2006Lat.: 45.92221 Long.: 13.85059Code: Bot_130/2006_DSC0967Habitat: mountain pasture; stony grassland; almost flat terrain; open, warm, sunny place; skeletal, shallow, calcareous ground; elevation 1.030 m (3.380 feet); average precipitations 1.800-2.000 mm/year, average temperature 7-9 deg C, border line between Dinaric and Sub-Mediterranean phytogeographical region. Substratum: soil.Place: Near the top of Mt. Mala Gora, 1.032 m (3.386 feet), aven ridge; Vipavsko, Slovenia EC.Comment: It is easy to recognize Rosa-spinosissima by its small, low to ground habitus, thin branches and dense, strait (never curved!), needle-like 'thorns', better said prickles. The bushes are frequently not much higher than surrounding grass and seldom higher than 0.5 m (1.5 foot). This alone distinguishes it from all other 24 species (Ref.:2) of wild roses growing in Slovenia, which are, when grown up, almost always taller than 0.5 m; most of them are about 1 to 3 m tall. The plant has stolons and hence it frequently grows in large spreading groups. It is not a common wild rose and can be found in warmer parts of the country.Ref.:(1) A.

Rosa multiflora Thunb. Syn.: Rosa cathayensis (Rehd. & Wilson) BaileyMultiflora Rose, Rambler Rose, Japanese Rose, DE: Fielblten-Rose, Fielbltige RoseSlo.: mnogocvetni ipekDat.: June 5. 2018Lat.: 46.342199 Long.: 13.668586Code: Bot_1136/2018_DSC2838Habitat: in a thicket of other shrubs and tall herbs (Corylus avellana, Fraxinus ornus, young, bush shaped Ostrya carpinifolia dominant); on steep pebble and sandy slope of a riverbank, south aspect; calcareous, semi-ruderal ground; sunny place; elevation 480 m (1.570 feet); average precipitations ~ 3.000 mm/year, average temperature 8-10 deg C, alpine phytogeographical region. Substratum: sandy soil.Place: Lower Trenta valley; village Soa, between the main road Bovec-Vri and right bank of river Soa, below stone escarpment of the road; immediately downstream from the bridge near the village church, East Julian Alps, Posoje, Slovenia EC. Comment: Rosa multiflora growing in the wild is a rare find in Slovenia. The plant is not native but introduced to Europe from East Asia mostly from Japan, China and Korea. In Europe it was once a garden plant and has been used as a rootstock for grafting cultivated roses. For the same purpose it was also introduced to several states of USA (Ref.:12), where it is nowadays considered noxious and quite invasive (ironically its planting was encouraged during the midst of last century by U.S. Soil Conservation Service) (Ref.:11)).The species sometimes but very rarely escapes gardens. But if it does it is capable to proliferate in the wild. The seeds of Rosa multiflora are dispersed mainly by birds and hence spontaneous, unexpected locations are possible (Ref.9). In Slovenia there exists only a few historical observations of Rosa multiflora. Also contemporary observations are few, most of them along rivers (Ref.1). Slovenian floristic key (Ref.:7 (2007)) as well as working materials for the Atlas of Flora Ref.:8 (2001) do not list this species for Slovenia at all. Also FloVegSi data base (Ref.10) includes good ten observations only of this species in the country. West of us, in Friuli Venezia Giulia, Italy, Ref.: 9 states only a few observations of this species, all of them are in the southwest part of the region away of Slovenia. However, Ref.: 5 states presence of it in Trieste region very near to Slovenian border. To our knowledge no observation has been documented so far in the upper Soa river region (Zgornje Posoje) including Trenta valley.It is interesting that most Rosa multiflora plants have thorns, but, according to some sources, there have been some plants observed without (Ref.11). All the plants of this observation are completely without them.Ref.:(1) Personal communication (conf.) with Dr. Igor Dakskobler and Dr. Branko Vre, Jovan Hadi Institute of Biology of the Slovenian Academy of Sciences and Arts.(2) M.A. Fischer, W.

Rosa arvensis Huds.Field Rose, DE: Kriechende Rose, Liege Rose, Wald RoseSlo.: njivski ipekDat.: July 15. 2008Lat.: 46.26316 Long.: 13.52651Code: Bot_282/2008_DSC1486Habitat: former pasture, grassland partly overgrown with bushes and scattered Fagus Sylvatica, moderately inclined mountain slope near the top of a rounded mountain ridge; south aspect, sunny and dry place; calcareous, skeletal ground, exposed to direct rain; elevation 1.130 m (3.700 feet); average precipitations ~ 3.000 mm/year, average temperature 4-6 deg C, alpine phytogeographical region. Substratum: soil.Place: Close to the top of Mt. Kobariki Stol ridge, above the dirt road, near mountain cottage on Mt. Starijski vrh, East Julian Alps, Posoje, Slovenia EC. Comment: Genus of roses (Rosa) is very beautiful. But it is taxonomically difficult. There are over hundred wild growing species known (hundreds of cultivars not taken into account, of cause), well over twenty are growing in Slovenia. More accurate numbers depend on to which botanical 'school one belongs'. Very frequent and numerous hybrids make determination of wild roses a 'small science by itself' like in genera Rubus, Alchemilla, Hieracium and some others. Only pros dedicate to a particular genus know, how to tell species, subspecies, varieties, forms and hybrids apart. For reliable determination of Rosa taxons one needs to study young shots and mature branches, leaves, flowers and hips in different stage of development. Such details like shape, size and distribution of spines, calyx leaves and their position after flowering is over (do they remain pointing radially, straight ahead or bend back, do they fall off early or late or not at all), hairiness of fruits, leaves, pistils, etc. must be taken into account. And, in addition, these entire traits are variable. In many cases one needs to visit a rose bush more than once in different seasons. Fortunately, Rosa arvensis seems an easy case for determination. Its typical long, glabrous pistils (almost as long as stamens), which are fused together into an inseparable bundle (see picture 6) and non-shining green leaves determine it well. In addition to Rosa arvensis such pistils are characteristic only for (also white blooming) Rosa sempervires. But the latter has distinctly shiny leaves and, doesn't grow in Alpine phytogeographical region of Slovenia but only in southwest part of it in warmer submediterranean phytogeographical region. Hence the determination of this find seems quite reliable.Ref.:(1) M.A. Fischer, W. Adler, K.
