Botanical Description
These plants are 5-12cm (sometimes weakly caespitose, multi-stemmed or with relatively short branches. The rhizomes are fibrous-rooted, thickened, becoming woody). The stems are proximally herbaceous or slightly woody, eglandular.
The proximal leaves are separated by evident internodes, spathulate, reduced in size distally. The mid and distal leaves are ovate to oblong or linear, 4-15mm, margins narrowly whitish hyaline, faces densely scabrous-hispidulous.
The heads are borne singly. The involucres are 7-10mm. The disc florets are bisexual, fertile. The corollas are 5.5-7.5mm.
The cypselae are 5-6mm, faces eglandular.
