Khosrov Forest State Reserve pear ("Pyrus"), rowan ("Sorbus"). The southern steep sunny and dry slopes are covered by juniper sparse forests. Caucasian oak ("Quercus macranthera") forests can be found at an altitude of 1600–2300 m above sea level, which are rather dense in Khosrov district of the reserve known as "Trchnaberd". Oak forests are accompanied by ash ("Fraxinus excelsior", "Fraxinus rotundifolia"), rowan ("Sorbus aucuparia"), pear ("Pyrus"), maple ("Acer") and others. Bushes are abundant in the forests, represented by different species of wayfaring tree ("Viburnum lantana"), honeysuckle ("Lonicera"), rose ("Rosa"), hawthorn ("Crataegus"). The vegetation in the forests is rich in grass (family "Poaceae" L.). Mountainous
Sorbus chamaemespilus in corymbs 3–4 cm diameter. The fruit is an oval red pome 10–13 mm diameter. It is the sole species in a group that has been called genus "Chamaemespilus" or "Sorbus" subgenus "Chamaemespilus", distinguished from other subgenera of "Sorbus" by the pink (not white) flowers with forward-pointing petals (not opening flat). More recently, it has become clear that the simple-leafed species traditionally included in "Sorbus" form a monophyletic group, and this species could be included in a clade called "Aria" (genus "Aria" or "Sorbus" subgenus "Aria"). Sorbus chamaemespilus Sorbus chamaemespilus, the false medlar or dwarf whitebeam, is a species of
