Etymology

Named in honor of Baxter’s fraternity, Phi Kappa Tau, commonly known as Phi Tau, “which has meant much to me”. David Hunt (Bradleya 4: 39-64. 1986) quotes Baxter as writing “in honor of my Fraternity, Phy Kappa Tau”, suggesting that Baxter misspelled the fraternity’s name, but Baxter did in fact write “Phi Kappa Tau”. Compare Copiapoa ahremephiana.
