This species is known from few gatherings: from the type gath­erings of the species and its synonym Lathyrus henanensis (neither of which were available for this revision). Two incomplete specimens collected by Augustine Henry may represent additional gatherings of this: Aug. Henry 6595 (BM) and a specimen dated 1889 (K).
