Self-compatible:
J. biflora (Mione et al. 2001)
J. darcyana (Mione and Yacher 2005)
J. paneroi (Mione & Leiva 1997)
J. procumbens (Davis 1986, p. 407)
J. sagastegui (Mione & Coe 1996)
J. sanchez-vegae (see this species' web page for details)
It is likely that all species of the genus are self-compatible: during nearly two decades of growing these plants, I have noticed that plants usually set fruit abundantly even in a nearly pollinator-free greenhouse.
It is possible that the combination of self-compatibility, predominant homogamy and presumed bird dispersal of fruits allowed Jaltomata to be successful at colonizing Islands (Galápagos Islands, one species; Greater Antilles, one species; virtual islands known as lomas formations along the coast of Peru, five or six species; virtual island Baja California, one widespread species).
Author's notes to self about future addition to this page: I could go through my Crosses data book to add to the list above: many collections of many species set fruit when manually selfed over the last 15 years.
