It is a native of Queensland, Australia, as well as of some of the 
Pacific islands, as New Caledonia and Fiji. In Hawaii the plant is 
cultivated, trees occurring at Ainahau at Waikiki, Airs. Jaeger's 
premises, on the Government Nursery Grounds and the largest in 
the garden of the late Dr. W. Hillebrand, who evidently introduced 
it into these Islands. 
Cerbera odollam Gaertn. 
Cerbera odollam is a small tree about twenty to twenty-five feet 
in height, with lanceolate to oblong lanceolate leaves, which are 
narrowed at both ends. The flowers are arranged in cymes, which 
are as long as the leaves, the flowers are white, about one and a half 
inches long, the tube is slender and the lobes spreading. The fruit 
is borne in pairs more or less united, or singly, and is two and a half 
inches or more long, ellipsoidal or ovoid in outline. 
This very poisonous tree is a cosmopolitan on the seashores of the 
tropics, occurring in India, China, Malay, Australia and Polynesia. 
It has been introduced into these Islands a few decades ago. The 
writer knows of two trees, one on the premises of the grammar 
school on Emma Street, formerly Princess Ruth Keelikolani's palace, 
and another on the Government Nursery grounds. 
The milky sap and the leaves have been used in India as an 
emetic, but their use has been condemned, as even moderate quan- 
tities possess so much poison as to be dangerous. The nut is also 
poisonous and narcotic, the green fruits having been employed in 
India to kill dogs. The kernel of the fruit is considered an irritant 
poison, which when taken internally produces vomiting and purging 
and is soon followed by collapse and death. The wood is soft-spongy 
and gray in color.

der, reaches a height of fifteen to twenty feet, is much branched

shining. The flowers, which are borne singly in the axils of the 
leaves and the branches, are bell-shaped, bright yellow, and very fra- 
grant, having the odor of the tea rose. The fruit is a subglobose,
