Triarch Incorporated’s name is based on a botanical slide
that illustrates three ridges of xylem found in the vascular cylinder of the Ranunculus root.
Our founder, George H. Conant, Ph.D., had three principles in mind:
Accuracy, Service, and Dependability.
He incorporated these into the Triarch logo based on the triarch vascular cylinder.
