The present plant is characterised by 4-merous flowers. Some authors regard the plant to belong to Vaccinium (HYLANDER 1945), and in such a case, Vacci.niiim Oxycocciis LINNAEUS and Vacciniit-m Oxycocciis subsp. microcarpu.m BLYTT are legitimate. The subsp. microccirpn-s is characterised by a smaller habit. The difference between subsp. quadripetalits and subsp. microca'rpii.s is as follows :. 1. Stem coarse; leaves oblong-obovate, 7-15 mm long ; young branches and peduncles pubescent; berries 10-18 mm in diameter .......... .0. qit.adripetalus subsp. qn.adl'ipetahl.s. 1.
