Glen Citrangedin

Glen Citrangedin (C.P.B. 48045) was raised from Calamondin pollinated with Willits citrange pollen by Walter T. Swingle at Glen St. Mary, Florida, in spring 1909. The USDA proposed the name in its August 1931 Circular 181. UCR also records it as Altamaha Citrangedin and describes the accession as polyembryonic.^⁠[4]⁠[1]

The small orange to reddish-orange fruit has acidic yellow-orange flesh and is chiefly used for drinks and flavoring. Accounts differ: UCR's 1988 observation called it sour and unpalatable, while The Mulberries' 2025 tasting described a useful orange-soda-like flavor with little flesh bitterness. That tasting reported approximately 18 g average fruit weight, 13.5 Brix and pH 2.8; these describe the reviewed sample, not a cultivar average.^{⁠[4]⁠[1]⁠[6]}

Historical reports describe an upright tree, mostly late-summer and fall fruiting, and greater cold tolerance than ordinary Calamondin; UCR lists October–November ripening at Riverside. Cold reports lack measured exposure details, and the USDA noted that many trees were on trifoliate-orange rootstock. Grower accounts also include seed-grown or uncertain-identity fruit, so their differing flavors should not be assumed to represent the original clone.^{⁠[4]⁠[5]⁠[1]⁠[7]}
