Premise: Chamaecyparis, common names cypress or false cypress (to distinguish it from related cypresses), is a genus of conifers in the cypress family Cupressaceae, native to eastern Asia (Japan + Taiwan) and to the western and eastern margins of the United States. The name is derived from the Greek "khamai", meaning ground, and "kuparissos" for cypress.
Hypothesis: Chamaecyparis are medium sized trees.
