Abstract
A new variety of pecan tree distinguished by its vigorous and widely spreading growth habit with longer branches each of which has many smaller and twiggy branches along its length which bear abundant nuts on the interior of the tree mass thereby adding greatly to the total production of nuts which are ordinarily produced mainly at the periphery of the tree mass. This tree is further distinguished by its prolific production of mature nuts which ripen evenly at about midseason and which have a superior cracking quality with a high percentage of nut meats of superior flavor and color.
