Revision of the North American Liliaceae: descriptions of some new species of North American plants; from the Proceedings of the American academy of arts and sciences, vol. xiv, issued July, , by Sereno Watson and American Academy of Arts and Sciences (page images at . 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. The taxonomic affinities of five species in section Micranthes .
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.

Bulletin of the AMNH ; v. 93, article 8 McDunnough, James H. (James Halliday), b. Abstract. With c. 85 species, the genus Micranthes is among the larger genera of the Saxifragaceae.
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.

Saxifraga in the narrow sense, as adopted here, includes most sections of the traditional genus as well as a majority of the species. In North America fewer species belong to Saxifraga than to Micranthes.
Eight species of Saxifraga are endemic to North America. A single introduced species has established itself in the flora area; other garden. Type species: Saxifraga fusca Maximovicz.

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.
