Orig. in Riverside, Calif., by Howard B. Frost, California Citrus Expt. Sta. Introd. in 1935. Three seedlings, doubtless nucellar, all Trovita, were grown from seeds found in one fruit in the main Washington Navel orange crop. The parent tree was not located, but the record of the fruit does not mention any peculiarity. Probably a bud mutation had occurred in an ordinary tree of navel orange; seed from crop of 1914-15; selected in 1928. <b>Fruit:</b> navel structure usually absent or rudimentary; flesh somewhat more tender and juicy than Washington Navel, which it resembles; two to six seeds, in a mixed varietal planting. <b>Tree:</b> more vigorous than Washington Navel; otherwise, resembles Washington Navel. The name is Esperanto for "found," suggested by the accidental finding of the seeds that produced Trovita.
