Identified as those of the European white elm, Ulmus laevis, hitherto unknown in Ireland, the seeds were grown by Coillte into 15,000 saplings. The cultivar was cloned from a tree planted as one of a line of 17 White Elms at Eibergen circa 1900, which developed a straight central leader. Jovanović, B. Neophyte. (2012): Seznam cévnatých rostlin květeny České republiky, Preslia 84: 647–811 [jako Ulmus laevis Pall.] Ulmus laevis var. A popular larval host plant of the white-letter hairstreak Satyrium w-album butterfly across Europe, the elm is now being planted by Butterfly Conservation and other groups to restore local populations decimated by the effects of Dutch elm disease on native or archaeophytic elms.

Ignatieva, M. E. and Stewart, G. H. 'Homogeneity of urban biotopes and similarity of landscape design language in former colonial cities', in: McDonnell, M., Hahs, A., & Breuste, J. Ulmus laevis - Russian, fluttering, or European white elm. celtidea. Ulmus laevis. Ord.—Urticaceae. 1: 225. [33] The first specimen to be reported in cultivation, in 1838, was at Whiteknights Park, Reading, which featured an elm grove;[34] the tree measured 63 ft (19 m) in height, suggesting it had been planted at the end of the 18th century. Effect of trace elements on the growth of seedlings of Pinus sylvestris, Ulmus laevis and Lonicera tatarica and the accumulation of carbohydrates. in reporting its presence, given that it w as. The European white elm (Ulmus laevis) is a fast-growing, medium-sized, deciduous tree mostly distributed across Central and Eastern Europe. In the province of Häme it is a typical species of the shores of Lake Vanajavesi, in rich forest soils achieving a diameter of over a metre, given a few centuries. Forest Genetics and Ecophysiology Research Group, School of Forest Engineering, Technical University of Madrid , Ciudad Universitaria, Madrid 28040, Spain. Seeds were germinated under constant temperatures of 20 and 25 degrees C and alternating temperatures of 25/15 and 30/20 degrees C. Within each temperature regime, seeds were subjected daily to the following photoperiods: total darkness and 8 hr photoperiod. Ulmus Linnaeus, Sp. 4. A variety celtidea from what is now the Ukraine was reported by Rogowicz in the middle of the 19th century, but no examples are known to survive. The European white elm can grow to over 30 m and just as wide. A deciduous tree, formerly planted but now rare and found in only a few woods and river banks. Leaves can reach 4”, smooth to mildly rough above and softly hairy beneath. [66] A line of similar monopodial trees grows (2019) on the island in the Lot at Entraygues, France. 'Ulmus laevis naturalized in Cards, VC46'. FAMILY: ULMACEAE. Moreover, the apetalous wind-pollinated flowers are distinctively cream-coloured,[10] appearing before the leaves in early spring in clusters of 15-30; they are 3–4 mm across. [64] Softwood cuttings taken in June is also a reliable method; the cuttings strike very quickly, well within a fortnight, rapidly producing a dense matrix of roots. [13] [65] 'Simplicidens' is a very rare variety, the only example known to survive is at the National Botanic Garden of Latvia in Salaspils. [13] Trees planted in dry ground are notoriously short-lived. Height rarely exceeds 100’. Height rarely exceeds 100’. [23], Elwes observed that trees planted at Ugbrooke in Devon were infested with Cacopsylla ulmi,[24] which he had never found on any other elm in Britain, an affliction confirmed many years later by Richens, who discovered the specimens of U. laevis grown at Kew were the only elms in the Gardens afflicted by the louse, and the aphid Tinocallis platani. There are about 30 to 40 species of Ulmus (elm); the ambiguity in number results from difficulty in delineating species, owing to the ease of hybridization between them and the development of local seed-sterile vegetatively propagated microspecies in some areas, mainly in the field elm (Ulmus minor) group. Seed at center or toward apex of samara, compressed or ± convex, without endosperm; embryo erect; cotyledon flat or ± convex. laevis; Ulmus laevis … [22], U. laevis is essentially a riparian tree, able to withstand over 100 days of continual flooding,[26] although it is intolerant of saline conditions [11] Spanish trees were found to be calcifuge, preferring slightly acid, siliceous soils, and also drought-intolerant, their xylem vessels prone to drought-stress cavitation. riparian forest is composed mainly of elms (Ulmus laevis Pall.) The tree is of low economic value and, unlike other European elms, the timber is not appreciated. A large tree with an open, ascending, broad-oval crown which will eventually become round. Endemic to alluvial forest, U. laevis is rarely encountered at elevations above 400 m.[8] Most commonly found along rivers such as the Volga and Danube, it is one of very few elms tolerant of prolonged waterlogged, anoxic ground conditions.
