The status of this species has been disputed by some authors, who united it with C. sinensis or C. harringtonii. The latter species commonly has leaves terminating in a relatively long cusp (as in C. sinensis), while leaves of C. latifolia have an abruptly narrowed apex with a short cusp being less than 0.5 mm long. However, variants tending towards either form of leaf apex occur in C. harringtonii as well as C. latifolia, making the distinction less reliable. A comprehensive revision that would include molecular evidence is much needed. This investigation should, where possible, refrain from sampling among cultivated plants, as their identity or provenance can be muddled to start with.
Although no uses have been recorded of this species, its uses will probably be similar to other species of its genus, including use of the wood for fuel and timber, and for traditional medicine.
