Carex cephalophora Muhl. ex Willd., Oval-headed Sedge (Section PHAESTOGLOCHIN)
This species has a compact triangular shaped inflorescence that is unique in the Renfrew County flora. It has only been found at one location in Renfrew County (the Deacon Escarpment) on a steep rocky slope associated with Carex siccata, Campanula rotundifolia and Penstemon hirsutus. Those species are indicative of fairly dry non-acidic soil. While this seems to be a unique find, this species has been recorded frequently just 100 kilometers directly east under very similar conditions along the Eardley Escarpment in Gatineau Park, Quebec (see Figure 3).
