A noteworthy feature of the botany of the coast of tropical Queensland is its alliance with the Malayan Archipelago and India. Most of the related plants do not occur in those parts closest to other equatorial regions in the geographical sense, but in localities in which climate and physical conditions are similar. Probably there are more affinities in the coastal strip of which this isle is typical than in all the rest of the continent of Australia. One prominent example may be mentioned-viz., “the marking-nut tree.” When the distinctiveness of the botany of the southern portions of Australia from that of the old country began to impress itself on the earliest settlers, the miscalled native cherry was the very first on the list of reversals. The good folks at home were told that the seeds of the Australian cherry “grow on the outside.” The fruit of the cashew or marking-nut tree betrays a similar feature in more pronounced fashion. The fruit is really the thickened, succulent stalk of the kidney-shaped nut. The tint of the fruit being attractive, unsophisticated children eat of it and earn scalded lips and swollen tongues, while their clothing is stained indelibly by the juice. Botanists know the handsome tree as SEMECARPUS AUSTRALIENSIS, but by the indignant parent of the child with tearful and distorted features and ruined raiment it is offensively called the “tar-tree,” and is subject to shrill denunciations. The fleshy stalk beneath the fruit is, however, quite wholesome either raw or cooked, but the oily pericarp contains a caustic principle actually poisonous, so that unwary children would of a certainty eat the worst part. The tree, which belongs to the same order as the mango, has a limited range, and there are those who would like to see it exterminated, forgetful that in other parts of the world the edible parts are enjoyed, and also that a valuable means to the identification of linen is manufactured from it. A tree that is ornamental, that provides dense shade, that bears pretty and strange fruit, an edible part, and provides an economic principle, is not to be condemned off-hand because of one blot on its character. An Indian representative of the genera produces a nut which when roasted is highly relished, though dubiously known as the coffin-nail or promotion nut, but there is no reason to believe that it is specially indigestible unless eaten in immoderate quantity.
