Collection of glass plate negatives taken between c.1890 and c.1949 detailing plants and views at RBGE.

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.
