up to 10 cm wide and 15 cm long. The leaflets range from pointed to more frequently
rounded or obtuse.
The inflorescence of variety thompsonii extends well
above the leaves. The inflorescence of variety capitatum is at mid stem,
below the leaf blade (The flower stem is less than 5 cm long.). The inflorescence
of variety alpinum is usually found at ground level. It is ball-like
with numerous white, lavender, or purplish blue flowers from 5-9 mm long. The
stamens extend well past the throat of the corolla.
