Parentage/Origins: From China. Parents unknown.
Roostock of accession: Yuma Ponderosa lemon

Notes and Observations:
12/22/1987, EMN: Suspected as a new variety based on a letter from Tsuin to Reuther in 1980. Most fruits are small to medium in size but some older fruits are large; this appears to be a typical-type fruit; elongate with a blunt nose and medium yellow rind. Rind smooth on small fruits but bumpy and furrowed on large fruits. Moderately thick rind, light yellow flesh, sour, seedless.
12/5/2006, DK & TS: Small to medium in size; pear-shaped; seedless; thin-medium rind; juicy, fruity, very tart. Fruit is very fragrant. Tree medium in size; lots of red in young foliage. From China.
Availabilty: Not commercially available in California.
