Donald Angus Collection of Botanical Prints Donald Angus' collection of botanical prints are housed at the Bishop Museum, Foster Gardens, the National Tropical Botanical Garden, and the University of Hawai'i at Manoa Hamilton Library. These exquisite illustrations were published in monographs and journals mainly in the 18th and 19th centuries. They reflect the enthusiasm of scientists, and the popularity of the exotic flora being introduced and cultivated in European botanical gardens. Many prints in the Angus collection are from Monandrian Plants of the Order Scitamineae by William Roscoe (1753-1831). Roscoe, a wealthy banker and amateur botanist, founded the Liverpool Botanic Garden in 1802.
