USDA Circular No. 181 (1931), Glen Citrangedin account, states that the Calamondin was pollinated with pollen of the Willits citrange. The recorded parent roles are therefore Calamondin seed parent and Willits Citrange pollen parent. UCR CRC 3573 separately reports Willits citrange × Calamondin without specifying direction. The stored ancestry percentages are separate schematic estimates, not genetic measurements.

Revision: Correct the existing parent roles to match USDA Circular No. 181, which states that Calamondin was pollinated with Willits citrange pollen.
