A user suggests that this Japanese entry be cleaned up, giving the reason: “Lemma belongs here, not at 紫詰草(murasaki tsumekusa, literally “purple + clover”), per monolingual JA resources. That term appears to be a less-common alternative name. Also, etymon 詰草(tsumekusa) just means "clover", not necessarily "white clover".”
Please see the discussion on Requests for cleanup(+) for more information and remove this template after the problem has been dealt with.
