In zoology and anatomy, the development and production of a couple of things collectively; original union; junction from the very first: as, the connation associated with the feet of a palmiped bird by their-webs; connation of two procedures of bone tissue which occur by a, single center of ossification. Connation is an early on and more intimate or full union than confluence. See confluent, 2.
In botany, the act of developing together, and/or condition to be cultivated collectively, such as connate leaves or petioles. See connate leaf (cut), under connate.
