Museums hold 48 specimens collected within 10 miles of Siam between 1894 and 1969: 37 Animalia, 10 Plantae, 1 Fungi. 12 distinct Species records are shown. Collected by Caldwell, Class & Daiber, F. C. (Frank C.), Collector(s): R. F. Lozin and others. Each is a physical object with a catalogue number, and each entry opens the museum's record. This is what was collected and kept, not a survey of what lives here - nothing can be concluded from a species being absent.

The eight closest, with where each one stands in the county. Distances are straight-line, computed from the Geographic Names Information System coordinates.

Matched on this settlement's Geographic Names Information System number rather than its name, so it cannot be a different place of the same name in another state.

This settlement is recorded in the Geographic Names Information System as feature 1049178. The sheet list is computed by point-in-boundary test against the United States Geological Survey's historical topographic inventory.
