When cypresses were discovered in the Santa Cruz Mountains in 1881, they were first identified as " Cupressus goveniana ", but Jepson ( 1909 ) considered them to be " Cupressus sargentii ".

"Cupressus abramsiana " is in some respects intermediate between " Cupressus goveniana " and " Cupressus sargentii " in morphology, and two studies have suggested ( without conclusive proof ) that it could be a natural hybrid between the two.

Subsequent authors have either followed Wolf in treating it as a species ( Griffin & Critchfield 1976, the 1993 edition of the Jepson Manual, and Lanner 1999 ), or within " Cupressus goveniana " as either a variety ( " Cupressus goveniana " var . " abramsiana " ( C . B . Wolf ) Little; as in Little ( 1970 ), the " Gymnosperm Database " and Farjon ( 2005 ) ), or not distinguished at all within " C . goveniana " ( " Flora of North America ")
