This weedy plant was seen below the trail on a rather steep slope with a disturbed habitat beneath an open canopy oak woodland. This plant is surely non native. It is quite large, measuring almost 120 cm in height, but its heavy top has rendered it essentially prostrate.

Description

This Calamagrostis was seen atop an exposed sunny clifftop. P. Warner has logged C. nutkaensis and C. bolanderi both at Salt Point State Park; however the flower spike is not necessarily sufficiently developed to be determinative. Present number of nodes on the nascent spikes suggest nutkaensis, but lack of dense tufting of this 30 cm high plant suggest bolanderi.
