Source: Received as seed from Yangambi State of INEAC, Belgium, 1958.
Parentage/origins: Parents unknown.
Rootstocks of accession: Carrizo citrange, C-35 citrange
Season of ripeness at Riverside: Year round
Season of flowering at Riveside: July to December
Notes and observations:
11/1958: From a total of 15 seeds: 14 singles & one double.
EMN, 12/22/1987: More a shrub than a tree. Fair now but probably not adapted to Riverside as an ornamental. Foliage is unattractive yellowish-green now. No fruits but blooms and flower buds are present now-- poor tree is confused; probably thinks Santa Claus is coming but will get Jack Frost instead.
