Plant Description:
A tree approximately 25 ft. tall, with mostly mature fruit, some flowers and some green pods also present. Mature fruits have lots of insect damage (borer holes) and not many seeds remaining within those examined closely, even in pods that have not yet dehisced. This point represents the lower extent of this population; I hiked up to first easily accessible trees. Moderate SE slope, species common in area cross the uluhe-covered ridges and gulches.
