4a. Lotus corniculatus var. corniculatus

百脉根(原变种) bai mai gen (yuan bian zhong)

Plants subglabrous or scattered sparsely white puberulent on vegetative parts and calyces. Umbels 3-7-flowered. Flowers 11-18 mm. Corolla yellow or yellow with orange parts or stripes. Calyx teeth equaling, shorter than, or longer than calyx tube, narrow part of 2 upper calyx teeth more than half their length. 2n = 24.

Moist and weak alkaline soil of fields, grasslands, and ravines. Provinces of upper and middle Chang Jiang, NW and SW China [N Africa, SW Asia, Europe; introduced in Australia and North America].

The occurrence this variety in China needs to be confirmed, be­cause previously only diploid races of the Lotus corniculatus complex were reported to occur as native in E Asia (Larsen, Bot. Tidsskr. 54: 44-56. 1958; Grant, Canad. J. Bot. 73: 1787-1809. 1995). However, this variety may occur as an introduced taxon in China.
