Notes and observations

1/20/1989, EMN: A small round citron with a prominant nipple. Rind medium yellow, often ridged from base to apex. Rind relatively thin for a citron. Pulp light yellow, moderately juicy, extremely sour. Very seedy.

11/7/2006, DK & OJB: Papuan appears from its fleshy flowers to be a hybrid, but molecular marker studies show that it’s a pure citron. The tree is small, with small, rolly-poly fruit, strongly pointed, and very juicy, with a rather thin rind. It has fine-textured flesh, very acid, acrid. The leaves look right for a citron. Note the seedlings growing underneath the tree.
