London, Taylor & Francis, 1917. Large 8vo (26.0 x 17.0 cm). 226 pp.; 14 text figures, four plates. Original printed boards.

A very rare, fine study on the flora of this little-explored region, with many new species. The plates include views on landscapes and native people. Private library stamp on title, gaps in contents leaf and first text leaf with some text loss, otherwise very good. Stafleu and Cowan, 2009.
