Until this year, only two observations are found in the Calflora database for the Scepter Creek watershed. Both observations were of the rare plant Lewisia leeana. One observation was made in 1920 near Scepter Pass by Elizabeth Ferguson. The other was made near Crown Pass in 1971 by E R Blakley. The 34 observations listed for this poorly studied area were made on 25 July 2014.
