This accession was receieved as a tangerine and assigned the species name C reticulata. However, it is classified as C sunki by Condit et al (1937), who state on p 10: "9. Citrus sunki Hort. ex Tanaka.
"Tree upright with thorny branches bearing a small sour fruit somewhat like a tangerine. Rind much thinner and lighter in color than that of C. ponki. Not edible but used for candy making. Seedlings largely used for stock in the Ch'ao-an district and in Formosa.
"9.a. Var Nin-kat or Tung-hung-kat is a typical late variety of the kat group so far not classified specifically. Fruit small with a star-like russet mark at the center of the apex; color cadmium orange. Season from late December to May; sour early in the season but later becoming sweet. A low-priced orange consumed on a large scale by the masses."
