Can anyone help me identify this citrus family relative that is growing wild in southern China about 50 km east of Guangzhou? The iNaturalist photographer thinks it is a kumquat (e.g. Fortunella hindsii), but I am not convinced. www.inaturalist.org/observations/67433713 |

Probably a form of Glycosmis pentaphylla, not a kumquat. They are also called Lime berries. Also Triphasia trifolia.

There is also a tiny "quat" known as Procimequat, but the fruit turn orange not red.

But it is not trifoliate.

Always difficult to tell from one photo, but to me this doesn't look quite right for the Hong Kong Kumquat. The leaves seem more separated, possibly longer and narrower, and with a longer leaf stalk. The whole branch looks longer and more open than you would expect for C. hindsii = Fortunella hindsii = HK Kumquat. Procimequat looks similar to HK Kumquat but is a man-made hybrid which you would not expect to find growing in the wild. I would guess this is probably a form of Glycosmis but not necessarily the trifoliate form which is native to Australia. There are 11 different species of Glycosmis native to China and they are difficult to differentiate. Details at Flora of China and at Kew Science. |
