For each drawing, the scientific and/or common name of the specimen in Malay, and, occasionally, in English, was written in pencil.

Kwa Chong Guan extended this conjecture via stylistic comparison to identify the artists of Farquhar's drawings as from Guandong.

[1] Farquhar donated these in eight volumes to the Museum of the Royal Asiatic Society of Great Britain and Ireland on 17 June 1826.

In the book Natural History Drawings: The Complete William Farquhar Collection, Malay Peninsula 1803–1818, an article by Kwa Chong Guan suggests that there were two artists, one who usually framed his works as seen in the illustration of the durian and one who did the opposite of the latter.

[4] A second version containing prints of all 477 works in the Farquhar collection was published by Editions Didier Millet and the National Museum of Singapore in 2010.
