The monotypic Saxifragodes, from southern South America, does not appear to be related to Andean species of Saxifraga, which lack crystals, but rather to species of Saxifraga section Micranthes in North America.

    Two species of the garter snake in the genus Thamnophis are found in the same geographic region. These species are not likely to meet and attempt to reproduce because one lives mainly in the water, while the other species spends most of its time on land. This is known as A. behavioral isolation. B. habitat isolation. C. temporal isolation.

It is only distantly related to the morphologically similar genus Saxifraga, in which it has frequently been included as Saxifraga section Micranthes.

To study the molecular evolution of Micranthes, we analysed nuclear ribosomal (internal transcribed spacer, ITS) and plastid (trnL–trnF) Cited by: species, which are no longer capable of intercrossing.

In the past, Boykinia has been split into the following segregate genera: Boykinia and Telesonix (from North America) and Neoboykinia and Peltoboykinia (from Japan).

The situation is complicated by other closely related genera, the limits of which also need by: A revision of the New World species of Norrbomia (Diptera: Sphaeroceridae), including all American species previously placed used forthe North American speciespreviouslyplaced in that genus.
