illustrated over 1000 plant species. The majority of her illustrations have been created using pen and ink or brush with ink, but at times also graphite and digital painting. She typically draws her specimen in black and white, with minimal shadow, and frequently places the light sources in the image's upper left corner. She has also experimented with creating colored illustrations. When completing an illustration, Tangerini follows tradition in botanical illustration by focusing on plant morphology and internal parts of the flower rather than the color. Tangerini's illustrations have been featured in numerous scientific publications, such as The Flora of the Guianas, as well as a number of books. In 1980, she created a "one-man show of palm drawings" in the National Museum of Natural History and she curated the "North American Wild Flowers: Watercolors by Mary Vaux Walcott" exhibit in 1990. This collection was also held in the National Museum of Natural History. In 2013, she published the article Whatever happened to Bishopanthus, along with co-writers Vicki Funk and Harold E. Robinson, in the botanical journal PhytoKeys. In the same year, scholars Theodore H. Fleming and W. John Kress thanked Tangerini in the preface of their book The Ornaments of Life: Coevolution and Conservation in the Tropics for her help with the cover and a figure included in the text. As of 2015, Tangerini has been developing a website to catalog her work and those from other illustrators working in the herbarium. As of March 9, 2017, Tangerini remains the only botanical illustrator ever hired by the Smithsonian. Aside from her work in illustration, Tangerini has also given lectures and taught classes on the subject at several locations, including the Smithsonian Associates, United States Department of Agriculture, Montgomery College, Virginia Commonwealth University, the Corcoran School of the Arts and Design, and the Minnesota School of Botanical Art. She is a manager and curator for botanical art in the National Museum of Natural History's botany department, and runs the Smithsonian Catalog of Botanical Illustrations. She also serves as a board member on the American Society of Botanical Artists. Injury In 2005, Tangerini lost sight in her right eye following an unidentified injury. She was not given a clear diagnosis on the issue. Tangerini attributed the injury to too many years of working. After receiving surgery in the same year, she was identified as having diplopia in her right eye. Wagner
