According to kanjidic2, the character 麻 (u+9ebb) has the radical 53 (广). But according to Halpern and Unicode, the character is it's own radical (200). Who's right? (Actually radical 200 in Halpern and Unicode looks like 麻 but with the diagonal "tree roots" not actually touching the "trunks" and looking more like "儿" but Halpern gives 麻 as a variant.)
