The evergreen subshrubs are generally cushion to mat-forming, with densely tufted shoots bearing mostly awl (long, pointed spike) to needle or grass-like, prickle to spine-tipped hard-textured leaves. They have shortish, simple or branched flower stems which can be loose or dense. The summer-borne flowers are composed of a funnel-shaped calyx, usually with a flared membranous margin, and five spreading petals.[2]
