Abyssinian rose, Rosa abyssinica, with white flower, buds and thorny branches. Handcoloured copperplate engraved by Watts from an illustration by John Lindley from his own "Rosarum Monographia, or a Botanical History of Roses," London, Ridgeway, 1820. Lindley (1799-1865) was an English botanist who specialized in roses and orchids. Lindley wrote and illustrated this monograph when just 22 years old. He went on to edit the "Botanical Register" from 1829 to 1847.
