Notable among the flowers are the arum lily and the iris.
It is often associated with that form of inflorescence termed the spadix, and may be coloured, as in Anthuriuzn, or white, as in arum lily (Richardia aethiopica).
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.
On the lagoons and lower reaches of the rivers the Viha (Typhonodorum lindleyanum), an arum endemic to Madagascar, grows in great profusion to a height of 12 or 13 ft.
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.
The common British representative of the order, Arum maculatum Fig.2.
The underground stems (rhizomes or tubers) are rich in starch; from that of Arum maculatum Portland arrowroot was formerly extensively prepared by pounding with water and then straining; the starch was deposited from the strained liquid.
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.
In moist regions ferns and mosses, the arum and other broad flat-leaved plants are found.
The order is represented in Britain by Arum maculatum, a low herbaceous plant common in woods and hedgerows in England, but probably not wild in Scotland.
