Chamaerhodos erecta
 
Chamaerhodos

First Year Plant, Bottom

Oro Lake Regional Park
23-June-2011

The first year plants appear to consist of just a basal rosette. The stem appears to develop in the second year.  Marcescent leaves are those that remain attached to the plant after withering.

Note that the key to the genera in Flora of Alberta requires that calyx-bractlets be present.  In fact, this species does not have calyx-bractlets.
