Identification Key
1. Plants with rhizome-like caudex branches (becoming colonial or loosely matted); leaves linear, 0.3-2 mm wide, bases persistent (± sheathing branches of caudices)
1. Plants with rhizomes or crowns, sometimes enlarging by offsets from stem or caudex bases; leaves linear-oblanceolate to oblanceolate or narrowly spatulate, 2-14 mm wide, bases not persistent
2
2. Plants occurring singly; proximal leaves usually without a clearly distinct petiolar region, linear to linear-oblanceolate, mostly 2-4 mm wide, usually relatively few and not forming a prominent rosette (the basal and lower stem leaves strict to ascending); involucres 6-7.5 mm high; florets 3-6; corollas 4-5 mm long
2. Plants commonly occurring in close clusters; proximal leaves with a distinctly narrowed petiolar region, blade elliptic to oblanceolate, mostly 4-14 mm wide, crowded in a basal rosette (the leaves mostly spreading to somewhat ascending); involucres 4-6 mm high; florets 2-5; corollas 3-4 mm long
