<hw>Caustic-Plant</hw>, or <hw>Caustic-Vine</hw>, <i>n</i>. <i>Sarcostemma australis</i>, R. Br., <i>N.O. Asclepiadea</i>. Cattle and sheep are poisoned by eating it.
<hw>Cavally</hw>, <i>n</i>. the original form of the Australian fish-name <i>Trevally</i> (q.v.). The form <i>Cavally</i> is used to Europe, but is almost extinct in Australia; the form <i>Trevally</i> is confined to Australia.
<hw>Cedar</hw>,</hw> n</i>. The true Cedar is a Conifer (<i>N.O. Coniferae</i>) of the genus <i>Cedrus</i>, but the name is given locally to many other trees resembling it in appearance, or in the colour or scent of their wood. The New Zealand <i>Cedar</i> is the nearest approach to the true <i>Cedar</i>, and none of the so-called Australian <i>Cedars</i> are of the order <i>Coniferae</i>. The following are the trees to which the name is applied in Australia:—
Bastard Pencil Cedar—
<i>Dysoxylon rfum</i>, Benth., <i>N.O. Meliaceae</i>.
Brown C.—
<i>Ehretia acuminata</i>, R. Br., <i>N.O. Asperifoliae</i>.
Ordinary or Red C.— <i>Cedrela australis</i>, F. v. M. <i>Cedrela toona</i>, R. Br., <i>N.O. Meliaceae</i>. [<i>C. toona</i> is the "Toon" tree of India: its timber is known in the English market as Moulmein Cedar; but the Baron von Mueller doubts the identity of the Australian Cedar with the "Toon" tree; hence his name <i>australis</i>.]
Pencil C.—
<i>Dysoxylon Fraserianum</i>, Benth., <i>N.O. Meliaceae</i>.
Scrub White C.— <i>Pentaceras australis</i>, Hook. and Don.,
<i>N.O. Rutacea</i>.
White C.—
<i>Melia composita</i>, Willd., <i>N.O. Meliaceae</i>.
Yellow C.—
<i>Rhus rhodanthema</i>, F. v. M., <i>N.O. Anacardiacae</i>.
