Sorry, no etymologies found.


  • Like P. Montezumae, and under like influences, it shows much dimensional variation, and the leaf-fascicles are heteromerous, with the larger number in the southern part of its range.

    The Genus Pinus

  • In Mexico, for example, where snow-capped mountains lie on subtropical table-lands and extremes of temperature are in juxtaposition, the conditions are favorable for the production of species with heteromerous fascicles, and the number of leaves in the fascicle possesses often climatic rather than specific significance.

    The Genus Pinus

  • With some species, however, heteromerous fascicles are normal.

    The Genus Pinus

  • In the Malay Islands I found a heteromerous beetle which exactly resembled a Therates, both being found running on the trunks of trees.

    Darwinism (1889)

  • In Borneo a large black wasp, whose wings have a broad white patch near the apex (Mygnimia aviculus), is closely imitated by a heteromerous beetle (Coloborhombus fasciatipennis), which, contrary to the general habit of beetles, keeps its wings expanded in order to show the white patch on their apex, the wing-coverts being reduced to small oval scales, as shown in the figure.
