endarchies

Noun

endarchy (countable and uncountable, plural endarchies)

1. A system in which decision-making is centralized.
   • An endarchy which is so organised as to yield the minimum average path between any one element in the neurography and any other, and therefore gives rise to the shortest trains of reasoning within the system, is called a 'maximal endarchy'.1922, The British Journal of Psychology - Volume 12, page 189
2. A vascular system in which development starts nearest the axis center and spreads outward.
   • There is no doubt, however, that if endarchy is primitive in the protostelic and immediately derived types, it very rapidly gives place to mesarchy and exarchy in response to various demands, and it is not difficult to show how this may have occurred.1908, Sir Arthur George Tansley, Lectures on the Evolution of the Filicinean Vascular System, page 16
