G4?T2 Apparently Secure, Inexact Numeric Rank, Infraspecific Taxon - Uncommon but not rare (although it may be rare in parts of its range, particularly on the periphery), and usually widespread. Apparently not vulnerable in most of its range, but possibly cause for long-term concern. Typically more than 100 occurrences and more than 10,000 individuals.
The ranking is inexact.
The status of infraspecific taxa (subspecies or varieties) are indicated by a "T-rank" following the species' global rank. Rules for assigning T-ranks follow the same principles as the "G-rank"
G2 Imperiled - Imperiled globally because of rarity or because of some factor(s) making it very vulnerable to extinction or elimination. Typically 6 to 20 occurrences or few remaining individuals (1,000 to 3,000) or acres (2,000 to 10,000) or linear miles (10 to 50).
Perennial herb forming a flat mat or cushion-like mound up to 3.5 dm across from an intricately branching caudex; leaves all basal, short-petioled, the blade narrowly elliptic, 4-12 mm long, 1.5-3.5 mm wide, silky tomentose, the margins revolute; inf...
