The albums appear to be from William Purdom who travelled and collected plants with Reginald Farrer in Kansu / Gansu, northern China in 1914-1915, but one was compiled by Reginald Farrer and three relate to their collecting trip, so all 5 albums have been stored within the Reginald Farrer collection.
