Oenothera lamarckiana, Hort. Differs from the above in its densely red-tuberculate sts., broad crinkled Lvs. and much larger fls.: the stigmas are longer than the stamens and are pollinated by insects after the buds open: the buds are densely pilose and viscid: the fls. open suddenly about dusk and are immediately visited by the sphinx moths.—This species is unknown in the wild state. It is suspected by some of having had a horticultural origin, but by others considered more probable that it is a wild species which will yet be rediscovered in its native region. It has become the subject of an enormous literature, due to de Vries' discovery that it gives rise to distinct true-breeding derivatives (mutations) in every generation. These mutations are considered to throw light on the vexed question of the origin of species and horticultural varieties. The most interesting of them are a giant form, OE. gigas, and a dwarf, OE. nanella. Others are OE. rubrinervis, OE. lata, OE. brevistylis and OE. oblonga, whose names suggest the characters in which they differ from the parent species. They are cult. in most botanic gardens, but are not offered by the trade. OE. Lamarckiana closely resembles several beautiful species of the W. which have not been intro. into cult. OE. rubricalyx, Gates, is a derivative of OE. Lamarckiana, from which it differs in having the calyx-tube and segms. a fine rich red. G.C. III. 53:165. It is the only one of the mutations referred to above which has been intro. into general cult. It is known to the trade as "Sutton's Afterglow."
