TAXONOMY:
The scientific name of foxtail pine is Pinus balfouriana Grev. & Balf. (Pinaceae). There are 2 subspecies [8,32,39,47,68]:

Pinus balfouriana subsp. austrina R.J. & J.D. Mastrogiuseppe  southern foxtail pine
Pinus balfouriana subsp. balfouriana  northern foxtail pine

Foxtail pine, Great Basin bristlecone pine (P. longaeva), and Rocky Mountain bristlecone pine (P. aristata) share a common ancestor [83,109]. Taxa within the foxtail-bristlecone pine complex (Pinus, subgenus Strobus, section Parrya Mayr, subsection Balfourianae Englm.) are distinguished by growth form, bark, and differences in chemical composition [8,25,68,76]; however, these characters intergrade [32,39,68]. Foxtail and bristlecone pines readily produce fertile hybrids in the laboratory [93,109]. Disjunct distributions, and possibly other factors, prevent natural hybridization among the 4 taxa. Southern foxtail and Great Basin bristlecone pine populations seem geographically close enough for limited pollen dispersal (see General Distribution); yet to date (2004), southern foxtail Great Basin bristlecone pine hybrids have not been found in the field [8,60].

LIFE FORM:
Tree

FEDERAL LEGAL STATUS:
No special status

OTHER STATUS:
The World Conservation Union's Species Survival Commission (IUCB-SSC) lists foxtail pine as a lower risk, conservation-dependent species [45].
