Notes and observations

TJS: C-32 citrange consistently has a very low seed count and so it has been difficult to collect seed from in order to use as a rootstock. 

C-32 is reported to produce vigorous seedling trees and many nucellar seedlings. It has trifoliolate leaves typical of most F1 hybrids between Citrus and Poncirus.
