Notice

Colin Mills, compiler of the Hortus Camdenensis, died in late November 2012 after a short illness. As he always considered the Hortus his legacy, it is his family's intention to keep the site running in perpetuity. It will not, however, be updated in the near future.

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].
