Kartesz (1994, 1999) and FNA (2014) do not recognize varieties in this species; the USFWS had considered var. glabrum as a candidate for listing (FR 9/93).

Rank Reasons
Glossopetalon pungens is known from one occurrence in southeastern California on Clark Mountain and 15 in southern Nevada. It has a small global range over a handful of mountain ranges. The number of individuals appears to be relatively small. Variety glabrum is not recognized by most major floras but is, perhaps, worthy of recognition and has not been thoroughly studied. The species' habitat is vulnerable to mining, which however is highly unlikely at all of the Nevada locations.
Range Extent Comments
Glossopetalon pungens occurs in California and Nevada. It is found only in the Clark Mountain in California.
Occurrences Comments
There is only one known occurrence in California (Skinner 1997). In Nevada, there are 15 extant occurrences recorded (Nevada Natural Heritage Program 2019).
Threat Impact Comments
Habitat is vulnerable only to mining, which is highly unlikely at all of its Nevada locations (Jim Morefield, pers. comm. 1999).
