Flowers with mostly 9 perianth segments, white inside, mostly reddish outside; late winter. Fruit cylindrical, 5-10 cm long and often contorted. A hybrid raised by Soulange-Bodin near Paris in 1820 as a cross between m. denudata (seed) amd m. liliiflora (pollen).

Flowers initially goblet-shaped, mauvish pink but paler than the parent, white inside and spreading at maturity. In about 1975 Mrs Dolly Horn of Leongatha North pollinated m. campbellii × m. soulangeana 'Lennei' with pollen from m. × soulangeana 'Lennei'. (Rodney EmmerÃÂÂson, pers. comm.). A plant was grown from seed to flowering in September 1983 by Rodney Emmerson. Blue ribbon prizes were awarded to the flowers on two occasions at the Ferny Creek Horticultural Society and it has since passed into commerce although unregistered in early 1995. Summer flowers are produced but are not of the same quality as the spring ones.
Flowers larger and paler than those of 'Lennei'. Raised at Waitara, North Island, New Zealand by Felix Jury as a seedling of m. ×soulangeana 'Lennei' crossed with pollen from m. ' Mark Jury'. Flowers first produced in 1970.
Like m. denudata but a later-flowering plant with outer flower segments smaller. Introduced by Froebel, Zurich, Switzerland, c. 1905.
