"`Ironwood' and `Heartwood' of Tasmania; `Spurious Olive,' `White Plum' of Gippsland. An exceedingly hard, close-grained wood, used for mallets, sheaves of blocks, turnery, etc. The heartwood yields a very peculiar figure ; it is a very fair substitute for lignum-vitae."
<hw>Irriakura</hw>, <i>n</i>. an aboriginal name for the tubers of <i>Cyperus rotundus</i>, Linn., <i>N.O. Cyperaceae</i>, adopted by white men in Central Australia.
1896. E. C. Stirling, `Home Expedition in Central Australia,' Anthropology, p. 60:
"<i>Cyperus rotundus</i>. In almost every camp we saw large quantities of the tunicated tubes of this plant, which are generally called `Erriakura' or `Irriakura' by the Arunta natives. . . Even raw they are pleasant to the taste, having an agreeable nutty flavour, which is much improved by the slight roasting."
<hw>Ivory-wood</hw>, <i>n</i>. an Australian timber, <i>Siphonodon australe</i>, Benth., <i>N.O. Celastrinae</i>.
<hw>Ivy</hw>, <i>n</i>. a child's name for the ivy-leaf geraniums, especially the double pink-flowered one called Madame Kruse. In Australia the warm climate makes these all evergreens, and they are trained over fences and walls, sometimes to the height of twenty or thirty feet, supplanting the English ivy in this use, and covered with masses of flowers.
<hw>Ivy, Native</hw>, an Australian plant, <i>Muehlenbeckia adpressa</i>, Meissn., <i>N.O. Polygonaceae</i>; called also <i>Macquarie Harbour Vine</i>, or <i>Grape</i>. The name is widely applied also to the acclimatised Cape Ivy, or German Ivy (<i>Senecio scandens</i>).
1889. J. H. Maiden, `Useful Native Plants,' p. 46:
"`Native Ivy,' Macquarie Harbour Vine or Grape of Tasmania. The currant-like fruits are sub-acid, and were, and perhaps still are, used for tarts, puddings, and preserves; the leaves taste like sorrel."
<hw>Ivy, Wild</hw>, <i>n</i>. an Australian creeper, <i>Platylobium triangulare</i>, R. Br., <i>N.O. Leguminosae</i>.
