Given their strong association with the area, you might be surprised to learn that there is only one species of palm native to the entire state of California — the California fan palm (Washingtonia filifera), native to the southwestern United States and northwest Mexico. It is one of two recognized species in the genus Washingtonia, the other being the Mexican fan palm (Washingtonia robusta), native to western Sonora and Baja California Sur in northwestern Mexico. Both are among the palm tree species found in L.A., with the Mexican fan palm in particular reaching exceptional heights throughout the city.

Dr. Lorena Villanueva-Almanza, outreach coordinator at the California Botanical Society, specializes in the Washingtonia genus. As a plant taxonomist, her work focuses on understanding plant relationships and the many ways and names under which plants have been described across time — something she is currently engaged in for the Washingtonia. BHL is an invaluable resource for this work.

At the end of the twentieth century, the The Royal Botanic Gardens, Kew, The Harvard University Herbaria, and The Australian National Herbarium began collaboration on an ambitious project—to create an online index of names for all of the world’s vascular plants [1].

By combining the data in the nomenclatural indices of these three institutions—namely Index Kewensis, the Gray Card Index, and the Australian Plant Names Index—the collaboration created the International Plant Names Index (IPNI). Hosted by the Royal Botanic Gardens, Kew, today the database includes over 1.6 million records. As part of the provided nomenclatural information, IPNI includes bibliographic details linked to scanned literature in the Biodiversity Heritage Library (BHL) and links to taxonomic data through the Plants of the World Online.

Not surprisingly, given its role as a source of scanned literature for the Index, BHL is a vital resource for those working to build and maintain the IPNI database.

“I started working for the International Plant Names Index in 2013,” says Heather Lindon, Plant and Fungal Names Editor at the Royal Botanic Gardens, Kew . “I need to be able to look up protologues—the original place of publication of plant names and their descriptions. If the earliest place of publication isn’t known, we can use the name search in BHL to try to find it. Since our modern naming system dates to 1753, BHL has a lot of relevant literature for my work. Also, the rules of the International Code of Nomenclature that govern plant names apply to names published in the past, so consulting older works is still relevant for names being published today.”
