In Arum the blade is simple, as also in the so-called arum-lily (Richardia), a South African species common in Britain as a greenhouse plant, and in Caladium, a tropical South American genus, and Alocasia (tropical Asia), species of which are favourite warm-greenhouse plants on account of their variegated leaves.
The most common are the Natal lily with pink and white ribbed bells, the fire-lily, with flame-coloured blossoms, ixias, gladiolas, the Ifafa lily, with fuchsia-like clusters, and the arum lily.
Thus, the Lent lily is Narcissus Pseudonarcissus; the African lily is Agapanthus umbellatus; the Belladonna lily is Amaryllis Belladonna (q.v.); the Jacobaea lily is Sprekelia formosissima; the Mariposa lily is Calochortus; the lily of the Incas is Alstroemeria pelegrina; St Bernard's lily is Anthericum Liliago; St Bruno's lily is Anthericum (or Paradisia) Liliastrum; the water lily is Nymphaea alba; the Arum lily is Richardia africana; and there are many others.
Flowering plants include numerous species of terrestrial orchids, the socalled arum lily (Richardia Africana), common in low-lying moist land, and the white everlasting flower, found abundantly in some regions of Cape Colony.
Notable among the flowers are the arum lily and the iris.
