· Narrow gypsum endemics have a putative similar chemical composition to plants non‐exclusive to gypsum ( gypsovags), which may indie their similar ecological strategy as stress‐tolerant plant refugees on gypsum.
Gypsum, unlike cement, is a physical structure rather than a chemical structure. The needlelike gypsum crystals form a network to give the board its physical integrity The crystals are closely interwoven, giving the core most of its wet strength. After drying, the frictional forces of these crystals increase the strength of the core.
