1889. J. H. Maiden, `Useful Native Plants,' p. 588:

"Butter-Bush of Northern Australia; Willow-Tree of York

The berries are not poisonous—only bitter."

<hw>Poison-Bush</hw>, n. name given to a genus of poisonous Australian shrubs, Gastrolobium (q.v.).

Out of the thirty-three described species of the genus Gastrolobium, only one is found out of Western Australia; G. grandiflorum, F. v. M., is the poison-bush of the Queensland interior and of Central Australia. The name is also given to Swainsonia Greyana, Lindl., N.O. Leguminosae.

The Darling-Pea (q.v.), or Indigo-Plant (q.v.), has similar poisonous effects to the Gastrolobium. These species of Gastrolobium go under the various names of Desert Poison-Bush, York-Road Poison-Bush, Wallflower; and the names of Ellangowan Poison-Bush (Queensland), and Dogswood Poison-Bush (New South Wales), are given to Myoporum deserti, A. Cunn., N.O. Myoporineae, while another plant, Trema aspera, Blume., N.O. Urticaceae, is called Peach-leaved Poison-Bush.

1889. J. H. Maiden, `Useful Native Plants,' p. 129:

"These plants are dangerous to stock, and are hence called `Poison Bushes.' Large numbers of cattle are lost annually in Western Australia through eating them. The finest and strongest animals are the first victims; a difficulty of breathing is perceptible for a few minutes, when they stagger, drop down, and all is over with them. . . . It appears to be that the poison enters the circulation, and altogether stops the action of the lungs and heart."

Ibid. p. 141:

"This plant [S. greyana] is reported to cause madness, if not death itself, to horses. The poison seems to act on the brain, for animals affected by it refuse to cross even a small twig lying in their path, probably imagining it to be a great log. Sometimes the poor creatures attempt to climb trees, or commit other eccentricities."

<hw>Poison-Tree</hw>, or <hw>Poisonous Tree</hw>, n. another name for the Milky Mangrove. See Mangrove. The Scrub Poison-Tree is Exsaecaria dallachyana, Baill., N.O. Euphorbiaceae.
