The results of taxonomic and biomorphological analysis of rare exotic arboreal flora in botanical gardens of Ecuador and of Ukrainian Steppe shows that in bouth regions dominate species of Magnoliopsida, and one of the leading families are Pinaceae and Cupressaceae. In both floras were found 11 common families. There are several common species to both study regions: Cupressus lusitanica Mill, Cupressus sempervirens L., Ginkgo biloba L., Ficus carica L., Pinus patula Schiede ex Schltdl.. & Cham., Pistacia vera L., Platanus orientalis L., Punica granatum L., Sequoia sempervirens (D.Don) Endl., Thuja occidentalis L. and Vitis vinifera L. The rare exotic arboreal flora of Ecuadorian’s botanical gardens presents three types and seven classes of plants. The studied dendroflora of Ukrainian Steppes represents only four types. In both regions trees are the dominant type of biomes. The trees of first and fourth class of altitude are the most common in both. The type of woody vines of Magnoliopsida has a minor role in these rare exotic dendrofloras.
