Habit | Perennials; (compact); caudex branched; densely (silvery) pubescent, trichomes (sessile or short-stalked), 5–8-rayed, rays distinct, furcate or bifurcate, (umbonate, tuberculate and the center less so). | Perennials; caudex branched, (thickened); densely pubescent, trichomes (sessile), several-rayed, rays furcate or bifurcate, usually fused toward base, (strongly tuberculate). |
