The systematic sector is very important from the scientific and didactic point of view, constituting a real school for training students. The sector occupies a flat area, and the topography of the plants is determined by their classification in the corresponding families and by the position of the plant layers so that to be more accessible. The practical works and practical examinations focused on morphology, taxonomy, and ecology are carried out in this sector of the Botanical Garden. At the same time, the garden provides material for reproduction/propagation and microscopic preparations, and also gives the raw material for the elaboration license works, being a real documentation center both for students and for the teaching staff and other specialists. In the systematic sector, plant taxa are grouped by families and genera, the dominant ones being those from the flora of our country, many taxa being medicinal plants. Currently, the collection includes 683 plant taxa belonging to 81 families, which have been acclimatized in the culture system, in optimal natural conditions. The plants come from all over the world: Achillea ptarmica, Aconitum napellus, Allium ursinum, Delphinium palmatum, Geranium macrorrhizum, Iris ensata, Podophyllum peltatum, Polemonium carneum, Sida hermafrodita, Scopolia lurida, etc.

In the systematic sector is the “Oak Area”, located northeast to the main building of the University, being part of the secular oak forest “Plateau Corneşti”. Various species of trees (Ginkgo biloba, Abies alba, Pinus nigra, Pinus sylvestris, Gymnocladus dioica, Platanus x hispanica, etc.) and shrubs (Berberis thunbergii, Kerria japonica, Laburnum anagyroides, Cotinus coggygria, Cornus alba, Deutzia scabra, Callicarpa americana, etc.) were planted at the edge of the forest. In the forest grows a characteristic grassy blanket, which shelters delicate spring plants that grow in early spring and color this sector after each winter (Anemone nemorosa, Erythronium dens-canis, Scilla bifolia, Leucojum vernum, Galanthus nivalis, etc.). In mid-summer, the scent of flowers of Geranium phaeum, Vinca minor, Campanula persicifolia, C. glomerata, Telekia speciosa, and the long rustling of crickets calls visitors to relax on the benches of the alleys.

In recent years, a new sector was made, that of “Rare Plants”, which includes many endangered and rare species. From the internationally and nationally threatened plants, it can be mentioned: Fritillaria orientalis, Hepatica transsilvanica, Paeonia tenuifolia, Adonis vernalis, Angelica archangelica, Dictamnus albus, Digitalis ferruginea, Galanthus nivalis, Glaucium flavum, Gypsophila paniculata, Hyoscyamus niger, Periploca graeca, Polemonium caeruleum, Taxus baccata etc. In the future, it is necessary to develop this sector, expand and enrich it in the context of the mission of the botanical gardens, in the process of “ex-situ” conservation of endangered, threatened, and rare plants.
