crescive

From Latin crēscere (“to increase”).

crescive (comparative more crescive, superlative most crescive)

1. (archaic) Increasing or growing; marked by gradual spontaneous development.

   And so the prince obscured his contemplation

   Under the veil of wildness; which, no doubt,

   Grew like the summer grass, fastest by night,

   Unseen, yet crescive in his faculty.

   Shakespeare, Henry V
