hardy to 10°F [1] p. 22

Cross made by Dr. Swingle in 1909 in Glen St. Mary, Fl.

He writes "The calamondin has been utilized in a number of hybrids, the most promising of them being one in which it was pollinated with pollen of the Willits citrange.  This citrange, which has been previously described, is itself a hybrid, resulting from pollinating the Japanese trifoliate orange (poncirus trifoliata) with pollen of the common sweet orange (Citrus sinensis).  The citranges are as a class the hardiest of all evergreen citrus varieties or hybrids, but the fruit usually retains an objectionable quantity of musky oil, derived from the trifoliate parent, that necessitates special precaution in using the rather acid fruits for "ade" or preserves.  Most of the hybrids in which the citranges has been utilized have traces of this flavor-- much reduced, however, as in the Thomasville citrangequat, a hybrid of the oval kumquat (fortunella margarita) and the Willits citrange.  By hybridizing the Willits citrange with the calamondin, however, a fruit has been produced that is fully as hardy as the citrange parent but entirely free from the pungent oil usually associated with hybrids of trifoliate orange ancestry.  The tree, however, so closely resembles the common calamondin that some doubt might be raised as to the hybrid nature of the plant but for the occurrence of trifoliate leaves, especially in the juvenile stages" [2] p. 24

Glen citrangedin has the sour of Calamondin that has been kicked up a notch but lacks the pleasant scent and sweet peel. It is a pretty fruit though as they get a very deep orange bordering on red. (citrus.forumup.org)

My Notes: Compared to Thomasville, it is much less hardy and slower growing. Taste is more sour and less pleasant than Calamondin, no poncirus flavors.
