-arum, Osc. -azum.
- Spadix of Arum niaculatum from which the greater part of the spathe has been cut away.
An account of his Welsh campaigns is given in the Vitae duorum Off arum, but it is difficult to determine how far the stories there given have an historical basis.
A genus much represented is Culcasia, and swampy localities are thickly set with the giant Cyrtosperma arum, with flower spathes that are blotched with deep purple.
Arum italicum, Mill.
AROIDEAE (Arum family), a large and wide-spread botanical order of Monocotyledons containing about 1000 species in 105 genera.
The common British representative of the order, Arum maculatum Fig.2.
Arum maculatum, Cuckoo-pint.
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 details of the structure of the flower show a wide variation; the flowers are often extremely simple, sometimes as in Arum, reduced to a single stamen or pistil.
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 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.
In moist regions ferns and mosses, the arum and other broad flat-leaved plants are found.
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.
This in all probability arises from their salubrious climate, and the comparative sterility of their soil rendering them dependent upon the cultivation of the ground for the yam, the arum, and the sweet potato, their chief articles of food.
David, who spent some time in the Albert Edward district, that the creature dwells in the most dense parts of the primeval forest, where there is an undergrowth of solid-leaved, swamp-loving plants, such as arum, Donax and Phrynium, which, with orchids and climbing plants, form a thick and confused mass of vegetation.
ACORUS CALAMUS, sweet-sedge or sweet-flag, a plant of the natural order Araceae, which shares with the Cuckoo Pint (Arum) the representation in Britain of that order of Monocotyledons.
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.
