The fruit looks like a mandarin and was sold as 'Lo Kan' though the proper name appears to be 'Lokan' as evidenced by web searches. Each fruit is individually wrapped in a cellophane wrapper branded with the name 'zügar' and the caption "Just taste it!"

Observations of one fruit:

- About the same size and weight as Honey Murcott but more rounded;
- Rough textured skin similar to a basketball but much less pronounced;
- Slightly ribbed form similar to a baby pumpkin but much less pronounced; appears to have same number of ribs as segments;
- Some fruits have a slight neck similar to Minneola but less pronounced;
- Dimpled/recessed bottom;
- Thin, tight skin but easy to peel;
- 10 segments with 8 large, round seeds with light-green cotyledons;

Lokan = Ponkan Mandarin or Citrus reticulate cv Ponkan

Thanks, Laaz. The description for Ponkan in The Citrus Industry - Vol 1 fits this fruit.
