Aesculus chinensis

Aesculus chinensis, the Chinese horse chestnut (Chinese:七叶树 qi ye shu), is a tree species in the genus Aesculus found in eastern Asia.

The seed contains triterpenoid saponins[1] and flavonoids, such as aescuflavoside and aescuflavoside A, which are glycosides of quercetin.[2]

Notes

Comments

Typical Aesculus chinensis, described from Beijing, is planted, especially in temple grounds and by houses, and is not known with certainty in a wild state. Cultivated plants from S Jiangsu and N Zhejiang were described as A. chekiangensis (reduced to varietal rank under A. chinensis in FRPS), but they are scarcely distinguishable from plants in the Beijing region and in fact have some features that were thought to distinguish A. wilsonii, namely a thinner pericarp and a smaller hilum. Aesculus wilsonii was described from wild plants in Chongqing, W Hubei, and Sichuan, and in its typical form differs from A. chinensis in the above features and in having leaves abaxially pubescent (vs. ± glabrous) with a more rounded base (vs. cuneate). Within the range of A. wilsonii occur numerous intermediates with A. chinensis, as was noted by Hardin (Brittonia 12: 34. 1960), who hypothesized that the latter species might only be a cultivated form of the former. The comment in FRPS about native plants of A. chinensis existing in the Qin Ling mountain range (S Shaanxi) was possibly based on a comment by Rehder (in Sargent, Pl. Wilson 1: 500. 1913), which was questioned by Hardin (loc. cit.), who noted that the specimens he examined from Shaanxi "represent a form of A. wilsonii." Indeed, among the intermediates mentioned above are the same gathering seen by Hardin and another from Mianxian in SW Shaanxi. While extreme forms can easily be assigned to either A. chinensis or A. wilsonii, the existence of so many intermediates makes it impossible to delimit species and difficult even to justify infraspecific taxa. We have therefore decided to recognize one variable species, A. chinensis, but nevertheless to retain a separate status for the wild plants, as var. wilsonii.
