The common Oxlip is a hybrid more or less intermediate between the Cowslip and the Primrose.
The leaves form a radical rosette as in Primula (primrose, cowslip, &c.), or there is a well-developed aerial stem which is erect, as in species of Lysimachia, or creeping, as in Lysimachia Nummularia (creeping jenny or money-wort).
The flowers are solitary in the leaf-axils as in pimpernel, money-wort, &c., or umbelled as in primrose, where the umbel is sessile, and cowslip, where it is stalked, or in racemes or spikes as in species of Lysimachia.
