The nomenclature of Rosa kokanica is not fully clear and for this reason in some central-Asiatic floras the names Rosa divina Sumnev. or Rosa sumneviczii Korotkova are often used for this species. Forms of Rosa kokanica with densely pubescent and ± glandular young stems are separated as Rosa ovczinnikovii Koczk. From my observation, however, it appears that the indumentum characters as glands and hairs in the genus Rosa are generally ‘weak’, facultative. They occur with different frequency in different, not related species.

Kokand Rose (Rosa kokanica (Regel) Regel et Juz.). This species grows on stony slopes, along the banks of mountain rivers, and in shrublands. It is a xerophytic shrub with erect branches 1.5 to 2 m high, with red-brown bark and straight thorns that are small and slightly flattened at the base. Compound leaves with seven to nine elliptical or obovate leaflets are pubescent on both sides and thickly covered by short, stalked glandules. Yellow flowers are 1 to 2 cm long, with 4 cm pedicels. Spherical, dark-brown, almost black fruits have divaricate sepals.

Rosa kokanica (Regel) Regel ex Juz. (R. xanthina var. kokanica (Regel) Boul.) A suckering shrub up to 2 m, with reddish pubescent young twigs. Leaflets 5-7, aromatic, glandular beneath and on the margins. Flowers around 5 cm across; petals soon curling back. Sepals not leafy at their apex. Hips brownish. Found on rocky slopes and stony places in Afghanistan, and in central Asia, in the Pamir Alai and Tien Shan at 900-2800m....Flowers from May to July according to altitude. This species was introduced into cultivation by Jelena de Belder. It grows well, but is often defoliated by blackspot and does not flower after a cool summer, even in a hot dry position in full sun.
