Letters, 1892-1896 to Mrs. Ellis Rowan and Mr. Charles Ryan, Ellis Rowan's father. The letters discuss the identification of plants in Rowan's art work by Baron von Mueller, as well as an appeal to Rowan to support endeavours to mobilise an Admiralty expedition to the Antarctic. It also includes a draft preface to a proposed publication of Ellis Rowan's work, presumably written by the publishers, and biographical notes on Ellis Rowan, prepared in 1956.
