Triticum compactum erinaceum
Triticum compactum erinaceum, also called California Club Wheat or Mayview wheat, is an extinct subspecies of the hexaploid club wheat Triticum compactum. ''T. compactum erinaceum'' was a bearded, hairy rachis, red-chaffed wheat named for its appearance similar to that of a hedgehog. ''T. compactum erinaceum'' was thought to have disappeared before 1822.〔Davis, Horace. 1894. California Breadstuffs. (Chicago. The University of Chicago Press.)〕 However data from the United States Department of Agriculture indicates two additional specimen that were discovered and identified as ''T. compactum erinaceum'' more than a hundred years after their presumed disappearance.〔 The new specimen indicate that ''T. compactum erinaceum'' was grown in the United States until the dust bowl era, at which point it presumably disappeared. There have only been four recorded specimens of ''T. compactum erinaceum''.〔George W. Hendry, and Margaret P. Kelly. December 1970. ''The Plant Content of Adobe Bricks: With a Note on Adobe Brick Making''. California Historical Society Quarterly. p. 366〕
