Notes: Discovered in Big River Forest (TCF), MEN Co. by K. Heise and G. Hulse-Stephens in 2011. Previously known from only two occurrences from the central portion of the Monterey Peninsula; where fewer than 1000 plants seen in 1987, none in 1992, and only 22 in 1995. Seriously threatened by urbanization and altered fire regimes. Appears to be a fire follower. Possibly of hybrid origin. See Muhlenbergia 1:55 (1904) for original description and Madroño 59(3):167 (2012) for discovery of MEN Co. occurrence. |
