Distribution and ecology
In Australia a spontaneous escape from cultivation, recorded from eastern Qld, central coast of N.S.W., central S.A. and far northern W.A.
Originally from South America where its origins are obscure, now spread around the world. Wild specimens are not known but represent escapes from cultivation (see Solanaceae Source for further discussion).
Tomato belongs to a group of about 10 species of western south America and
The numerous cultivated forms are usually larger, the corolla 6–9-lobed, ovary multilocular and fruit 5–10 cm diam.
There is an enormous literature on the cultivated tomato: see for example
· C. H. Muller, A revision of the genus Lycopersicon, U.S. Dept. Agric. Misc. Publ. no. 382 (1940);
· L. C. Luckwill, The genus Lycopersicon,
· C. M. Rick, The tomato, Sci. Amer. 239: 66–76 (1978).
· bibliography and the early history and use of the tomato may be found in G. A. McCue, The history and use of the tomato: an annotated bibiography. Ann.

Most Solanum species are buzz pollinated and there have been pressures to introduce the European bumblebee to perform this task for tomato crops in Australia. An article advocating the use of a native Australian bee for this purpose can be s een at www.aussiebee.com.au/abol-009.html
