Evidentiary scope

The accession rests on two sources: the department's printed inventory entry for plant introduction 21780 (Inventory No. 14 (1909), p. 13) and the entry for PI 21780 in GRIN-Global, the database of the National Plant Germplasm System, as it stood on 27 October 2026. The inventory gives the collector, his number, the date, the district and a description of the crop and its uses. GRIN-Global states that the lot "no longer exists and can not be requested", so the page gives the lot as gone. No conservation priority is assigned.
