TAXONOMY:

The currently accepted scientific name of rubber rabbitbrush is Chrysothamus nauseosus (Pall.) Britt. (Asteraceae) [5,21,47,56,64,66,139,141]. Rubber rabbitbrush is described as the most complex and widespread species within the genus Chrysothamnus [7]. Some morphological characteristics are difficult to observe and overlapping characteristics are sometimes noted [54]. The following subspecies are commonly recognized.

C. n. ssp. albicaulis (Nutt.) Rydb. [5,56,64]  white rubber rabbitbrush
C. n. ssp. arenarius (L.C. Anderson) Welsh [5,21,64,141]  rubber rabbitbrush
C. n. ssp. bernardinus (Hall) Hall & Clem. [5,56,64]  rubber rabbitbrush
C. n. ssp. bigelovii (Gray) Hall [5,21,64,139]  rubber rabbitbrush
C. n. ssp. ceruminosus (Durand & Hilg.) H. M. Hall & Clem. [5,56,64]  rubber rabbitbrush
C. n. ssp. consimilis (Greene) Hall [5,56,64,139]  threadleaf rubber rabbitbrush
C. n. ssp. glabratus (Gray) Cronq. [141]   Welsh rubber rabbitbrush
C. n. ssp. glareosus (Jones) Welsh [21,141]  rubber rabbitbrush
C. n. ssp. gnaphaloides (Greene) Hall [66,141]  rubber rabbitbrush
C. n. ssp. graveolens (Nutt.) Piper [5,47,64,139]  green rubber rabbitbrush
C. n. ssp. hololeucus (Gray) Hall & Clem. [5,21,56,64,139]  white-stemmed rubber rabbitbrush
C. n. ssp. iridis (L. C. Anderson) Welsh [5,64,141]  rubber rabbitbrush
C. n. ssp. junceus (Greene) Hall [5,21,64,66]  rubber rabbitbrush
C. n. ssp. latisquameus (Gray) H. M. Hall [5,64]  rubber rabbitbrush
C. n. ssp. leiospermus (A. Gray) H. M. Hall & Clem. [5,21,56,64]  rubber rabbitbrush
C. n. ssp. mohavensis (Greene) Hall & Clem. [5,21,56,64]  Mojave rubber rabbitbrush
C. n. ssp. nanus (Cronq) Keck [64]  rubber rabbitbrush C. n. ssp. nauseosus [5,47,64,139]  rubber rabbitbrush
C. n. ssp. oreophilus (Gray) Cronq. [21]  rubber rabbitbrush
C. n. ssp. psilocarpus Blake [5,64,141]  rubber rabbitbrush
C. n. ssp. salicifolius (Rydb.) Hall [5,21,64,141]  mountain rubber rabbitbrush
C. n. ssp. speciosus (Nutt.) Hitchcock & Cronquist [21]  rubber rabbitbrush
C. n. ssp. texensis L. C. Anderson [5,64]  Texas rabbitbrush
C. n. ssp. turbinatus (Jones) Blake [5,21,64,66,141]  rubber rabbitbrush
C. n. ssp. uintahensis (L. C. Anderson) [5,21,64]  Welsh rubber rabbitbrush
C. n. ssp. washoensis (L. C. Anderson) Cronquist [5,21,56,64]  rubber rabbitbrush

Numerous races and ecotypes of rubber rabbitbrush have also been identified [95].
Certain subspecies occur across a wide ecological amplitude whereas others, such as C. n. ssp. salicifolius, are narrowly restricted in either habitat or range [7,89]. Intermediate morphological forms occur at the edges of the subspecies' geographic ranges [78]. However, Anderson [7] reports "all subspecies are relatively well-defined and often coexist with little or no genetic exchange."
