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.

Citrus sinensis ‘St. Michael’s’

This is a cultivar of Citrus sinensis (L.) Osbeck. For details of the Sweet Orange see Citrus sinensis ‘Chinese Oval’. ‘St. Michael’s’ orange was still grown in Western Australia at the beginning of the 20th century. ‘Fruit of first-class quality when grown under favourable conditions. Like the Navel, it is less hardy than some other kinds, and requires sheltered situations, when it is very prolific. Fruit, large, round, and somewhat flattened, solid; pulp fine and melting; medium thin rind, few seeds. If circumstances are not congenial it is a shy bearer, and the fruit is apt to lose its high character, the rind getting much thicker in either cold or hot locations.’ [Despeissis p.239/1903].
