Notes and observations

EMN, 3/1987: Medium-large fruit with light crop. Attractive fruit, peels & sections readily but: most fruit is on ground and it is still too sour to eat.

EMN, 6/1989: Memo of 10/15/70 (Reuther to Nauer): Mandarin variety called Som Kaeo (Crystal citrus) collected from Hua Hin market, Thailand 9/1970. Trees do better on poorly drained paddy soils bedded up for citrus than any variety observed. This variety is now rather rare, but mentioned by early French writer (de la Lovbere, 1693) on Siam. De la Lovbere spelled it Soum Keou to give french transliteration. Note: We originally received 2 lots of Som Kaeo seed from 2 different locations in Thailand. Som Kaeo I trees died- probably could not put up with Riverside climate- & we lost this budline. The current budline is sometimes referred to as Som Kaeo II.
