The genus Caladium established by Ventenat, Description des plantes nouvelles et peu 
connues, cultivées dans le jardin de J. M. Cels, ¢. 30. 1800, and Roemer, Archiv fiir die 
Botanik, 2:347. 1799-1801, is adopted from the Caladium of Rumph, Herbarium 
Amboinense, 5: 313-318. 1747. The only species mentioned in common by the two 
authors is Caladium esculentum, which should therefore be considered as the type of the 
genus; and since this species is congeneric with, or, indeed, is sometimes considered 
merely a variety of Caladium colocasia, Caladium is restored as the correct name of the 
genus. The combination Caladium colocasia, cited in the Index Kewensis as having 
been published in Robert Wight’s Icones for a different: species, I find not to have 
been published there, and it is therefore a valid name in its present use. 
The name Colocasia, on the other hand, even though Caladium was not to be 
applied to this genus, would be an untenable name, for it was proposed by Necker 
in 1790 for a genus the identity of which does not appear to have been definitely 
established, and again by Link in 1795 for still a different group. Either of these 
proposed uses would invalidate the application of the name as published by Schott 
in 1832.—W. F. W.

A tree usually growing near the shore. Leaves opposite, shining, coriaceous, with 
innumerable parallel veins at right angles to the midrib, oblong or obovate-oblong, 
obtuse or emarginate; flowers polygamous, in axillary or terminal racemes, pure 
white, fragrant; sepals 4; petals 4, rarely 6 to 8, like the inner sepals; stamens numer- 
ous, filaments in 4 bundles; ovary globose, stipitate; style much exceeding the stamens; 
stigma peltate, lobed; fruit 2.5 cm. in diameter, globose, smooth, yellow, pulpy. 
This tree is widely spread throughout Polynesia and occurs on the tropical shores 
of Asia, Africa, and Australia. It is often planted near habitations and is valued for 
its wood, for an aromatic gum which exudes from incisions made in its trunk and 
limbs, and for a medicinal oil obtained from its nuts. Seeds of this species were 
among those collected by Doctor Guppy in the Solomon Islands in the drift of the 
beach, having probably been carried there by ocean currents. 
When the leaves are put in water an oil rises to the surface. This is used in some 
parts of India as a remedy for sore eyes. In southern Polynesia and India the dark 
green fragrant oil expressed from the nuts, called dilo oil or domba oil, is used as a 
lamp oil and is an external remedy for bruises and rheumatic pains. The resin
