edit
Original species andCotoneaster uniflorus By comparison, the difference is that most of the leaves of this species are nearly round, the apex is blunt, the underside is densely covered with yellow fluff, the flowers are red, and there are hairs outside the calyx tube, while most of the latter leaves are oval, the apex is sharp and thin and round, when old, the underside is nearly hairless, the pollen color, and there are no hairs outside the calyx tube.[1]
The difference between the cotyledon variety and the previous variety is that the leaves are small, 8-10 mm long and 6-8 mm wide, the apex is blunt or slightly pointed, and the fruit mostly has three small nuclei.It is distributed in Maowen, Lixian and other high mountain areas in northwest Sichuan.[1]
