Notes

Tamarix chinensis  and Tamarix ramosissima  are both highly invasive within the western U.S.A. (Gaskin and Kazmer 2009). Tamarix ramosissima  is often treated as a synonym of T. chinensis  ( Welsh et al. 1993), however genetic evidence supports their treatment as distinct species, albeit with extensive introgression and hybridization across its introduced range in the United States ( Gaskin and Kazmer 2009). Plants sampled previously from southeastern Utah have been identified as either back-crossed T. ramosissima  or F2 hybrids ( Gaskin and Kazmer 2009); it seems extremely likely that our material would possess a similar genotype.

This species has previously been reported for the nearby San Rafael Swell ( Harris 1983). Only one population was encountered in the vicinity of MDRS, consisting of three shrubby trees and multiple seedlings, around Kent's Reservoir - a pond on the west side of Cow Dung Road north of MDRS (Fig. 47).
