Discussion

Of conservation concern.

Styrax redivivus has often been treated as an infraspecific taxon in S. officinalis Linnaeus of the eastern Mediterranean region. Morphological and molecular data (P. W. Fritsch 1996, 1999, 2001) provide evidence that strongly supports its species status. These data also establish the Texas species S. platanifolius as the closest relative of S. redivivus, and the two species together form a clade that is sister to S. officinalis.

Characters used to justify recognition of var. fulvescens of southern California have been shown to be clinal from north to south across the range of Styrax redivivus (P. W. Fritsch 1996b) and are here considered taxonomically inconsequential.

Another binomial sometimes used for Styrax redivivus is S. californicus, but this name does not have priority, having been published two years later than the basionym Darlingtonia rediviva (that generic name was applied later by Torrey to the genus of pitcher plants and is now conserved). Styrax californicus is a superfluous name, based on the same type as Darlingtonia rediviva.

Although Styrax redivivus extends from Shasta County to San Diego County, its occurrence is sporadic and infrequent. The ecological factors involved in the maintenance of this species, such as seed ecology, fire tolerance, and habitat requirements, are poorly known (P. W. Fritsch 1996b).
