Horticultural & Botanical History

‘This beautiful Cereus is distinctly stated by Dr. Lindley to be a hybrid production, raised by Mr. Mallison, gardener to Sir Samual Scott, from seed of Cereus speciosissimus, fertilized by C. flagelliformis.’  [BM t.3822/1840].  Introduced to Britain before 1837.  [Otto & Dietrich].

‘Cereus smithii Pfeiffer (Enum. Cact. iI. 1837) is a generic hybrid produced by adding the pollen of this species [Aprocactus flagelliformis] to one of the species of Heliocereus and was made by an English gardener, Mr. Mallison.  It is figured in Curtis's Botanical Magazine for 1841 (67: pl.3822) and in Edwards's Botantical Register (19: pl. 1565) and it was said to be one of the best hybrids which had yet been produced.’  [Britton & Rose – The Cactaceae vol.II, p.218/1920].
