Byxmyx was an Iotian man of the 22nd century. Byxmyx served as a Chief Administrator on Sigma Iotia II. He met with Captain Stuart Mann of the USS Horizon when it visited the planet in 2102 SFC (c. 2176), and endeavored to make its crew feel at home. After the two men walked through Byxmyx's garden, and Mann described a formal English garden, Byxmyx uprooted his own garden and laid down a new one just like it, with the closest equivalent Iotian plants.
