endarchy

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
   • We take it then that the central elements of the personal endarchies of all the members of the ideal Commonwealth we are considering, will have in common certain purpose-elements that correspond to the central essences of the endarchy of science.1947, Edgar Bradshaw Castle, Education and World Citizenship, page 241
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
   • Exarchy, endarchy, and mesarchy are all found within comparatively small groups, and the actual course of evolution seems to affect the position of the protoxylems much more freely and rapidly than in the other great groups of vascular plants.2013, Frans Verdoorn, A.H.G.
