Шаблон:Short description Шаблон:Speciesbox

Citrus halimii, or mountain citron, is a citrus with sour fruit. Historically placed within the polyphyletic grouping of papedas, it has since been determined to be a wild species most closely related to the kumquats, and is not related to the true citron. It was first discovered and catalogued in 1973.[1]

Distribution

Citrus halimii is quite rare and poorly studied. After its initial 1973 discovery and description, it has been observed in only a handful of locations scattered across Southeast Asia: Thailand and Malaysia (the locations of the first discoveries), along with isolated stands in Indonesia.[1]

Description

Citrus halimii is a midsized evergreen tree, with a mature height of Шаблон:Convert; it is somewhat less thorny than other citrus. Like other papedas, the halimii has relatively large leaves, with a long, winged petiole.[1]

The fruits of C. halimii are edible, but sour. They are round and small, measuring about Шаблон:Cvt in diameter. The rather thick rind eventually ripens to yellow or orange-yellow; internally the rind is tightly bound to the flesh. The yellow-green segments are filled with a number of large seeds, and a small quantity of juice.[1]

Taxonomy

Historically, limited characterization made appropriate taxonomic placement of the mountain citron unclear, with particular uncertainty over whether it was a natural hybrid or a pure wild species. Some phylogenies placed the mountain citron within Swingle's grouping of inedible citrus, the subgenus Papeda, but this grouping proved to be polyphyletic. A 2022 study of the genomics of the mountain papeda revealed it to have low levels of heterozygosity, consistent with it being a true citrus species and not a hybrid variety. Its genetic markers, along with the profile of its essential oils, showed it to be most closely related to kumquats.[2]
