Description: The Wood Sorrel, (Oxalis carnosaSN|22455]]SN|22474]]), is generally included within (as a synonym of) Oxalis megalorrhizaSN|22455]]SN|22455]], suggesting that there is not really a fundamental difference between the two. The name carnosa, meaning "fat, succulent", refers to the swollen rootstock and short frutticose stems leafy and floriferous only at apex. The succulent roots helps distinguish this sorrel from the other herbaceous species.

Cultivation and Propagation: This is a winter/spring-grower, but can grow all year.
Reproduction: Seeds. Of the three fully succulent Oxalis species grown, only O. megalorrhiza (syn: O. carnosa) qualifies for this list. Also it is the only succulent Oxalis in general cultivation that seeds. These are produced in the typical explosive capsules of this genus that ensures the seeds are dispersed up to a few metres from the parent. After Umbilicus rupestrisSN|23473]]SN|23473]] it is the next biggest nuisance in the succulent collections.
