Robert Dale Kloppenburg is definitely a dedicated botanist. As of January 2018 – when he celebrated his 97th birthday – he has named 234 plant species, mainly in the flowering genus Hoya, which has been his focus for close to forty years since his retirement.

Kloppenburg and the International Hoya Association, of which he is president, have made some generous contributions to the Biodiversity Heritage Library, with funding of the Expanding Access to Biodiversity Literature project. Currently available on BHL are:

• Fraterna : Official Bulletin for International Hoya Association (1991-2006): Contributed by International Hoya Association and digitized by Harvard University Botany Libraries and The New York Botanical Garden, LuEsther T. Mertz Library.
• Hoya New (2013-2017): Published and contributed by Robert Dale Kloppenburg.

Fraterna provides a wealth of information on Hoya species and hybrids, for botanists and horticulturalists, as well as the association’s news updates.

Hoya New presents new species descriptions with photos and identification keys.

Also currently available on BHL are Kloppenburg’s titles:

• Ganges Hoya (2008)
• Malaysian Hoya Species : A Monograph (2004)
• Samoan Hoya Species : Preliminary Presentation (2014)

The International Hoya Association originated in 1988 as a USA west coast interest group which published a newsletter, first bi-monthly and then quarterly. By the end of their second year, international interest had allowed the group to expand to a non-profit with global membership. An affiliated group, ‘Svenska Hoya Sõllskapet’ based in Borlõnge, Sweden, also publishes a quarterly magazine about hoyas.

What are these plants? The association’s website describes the diverse genus:

“The genus Hoya is found in South East Asia through Australia. They are adaptable plants found everywhere from true rain forests through the slopes of the Himalayas, from semi-arid niches in Australia to damp forests. They range from vines, the most common form, to shrub-like growth. Most are epiphytic [growing on other plants]. Hoyas are in the family commonly known as milkweeds.”

“What interests me most about hoyas is the vast diversity, the genetic differences and their possible evolutionary significance,” Kloppenburg shared in an interview in Fraterna. “I am of the opinion that we have collected and identified less than 1% of the wild hoya species.”

As an opening message for Hoya New, Kloppenburg explains how the work of horticultural professionals and hobbyists can contribute to the conservation of biodiversity:

“When a species is collected from the wild, I feel it is wise to identify it, propagate it, and name it. In this way it will eventually get into the commercial channels, be distributed to all those interested in the genus and thus be preserved. If in the future the species is lost through natural causes or forest destruction it will still be here on earth in your collection.”

Kloppenburg began studying the genus Hoya in the Philippines in 1981. He had graduated from the University of California, Berkeley, shortly after WWII and worked as a plant breeder research agronomist. Since his retirement in 1986, he has continued to study hoyas, traveling extensively in the South Pacific. His data has been donated to UC Berkeley. In 2016, he reached out to Smithsonian Libraries to offer publications, and agreed to contribute the material to Biodiversity Heritage Library. His assistant, Karen Case, assisted with the permissions process.

“It has been a most exciting journey to be hosted with such a prestigious organization as the Biodiversity Heritage Library, for which I will be eternally grateful,” Kloppenburg says. “I hope my work will help others to become interested in hoyas, and that they will carry on the discovery of new species in the future.”

Meanwhile, he’s still studying plants in the genera Hoya, Dischidia and Eriostemma. “I no longer travel, so I depend on others, mainly in the Philippines, to send me material,” he says.

Many thanks to the International Hoya Association and to Robert ‘Dale’ Kloppenburg for their commitment to sharing biodiversity research, and to Karen Case for helping to facilitate the process.

As part of the Expanding Access to Biodiversity Literature project, an interesting title was added to BHL from Yale University’s Harvey Cushing/John Hay Whitney Medical Library and the online Medical Heritage Library: An essay on the antiquity of Hindoo medicine, including an introductory lecture to the course of materia medica and therapeutics, delivered at King’s College, by physician-botanist John Forbes Royle.

Title page of An essay on the antiquity of Hindoo medicine, including an introductory lecture to the course of materia medica and therapeutics, delivered at King’s College, by Royle, J. Forbes (John Forbes), 1799-1858. London, Allen, 1837. Digitized by Yale University via the Medical Heritage Library. http://s.si.edu/2mtstTx.

This work from 1837 documents the materia medica (pharmacology) of India, and explores the historical exchange of medicinal knowledge between cultural groups of India, Arabia, Persia, Greece and China. Including details in botany, ecology, minerology and astronomy, it’s an intriguing interdisciplinary resource that can also be read for insights on its Western author and this period in time.

John Forbes Royle (1798-1858) traded his plan to join the British army for an unexpected interest in natural history. He was born at Kanpur, India, and would return to India after attending Edinburgh High School and the East India Company’s military academy at Addiscombe. Inspired by the mentorship of physician Anthony Todd Thomson, Royle chose to pursue medicine as a means to further his study of botany. He became an assistant surgeon with the East India Company, and in the following years worked at several locations across northern India, where he studied medicines from bazaars, employed collectors to amass a collection of economic plants, and became superintendent of the garden at Saharanpur. He earned the titles of MD in 1833 and Professor of Materia Medica at King’s College, London, in 1836.

An excerpt from Essay on the antiquity of Hindoo medicine demonstrates Royle’s interconnected thinking on medicine:

“There are, however, two branches of this extensive science [botany], respecting which I am desirous of making a few observations; one is the connexion between the Structure and Natural affinities of plants, and their Physical and Medical properties; and the other is the Geographical distribution, especially as connected with Climate. Both are important subjects, whether we consider them in a scientific or a practical point of view. The one teaches us the laws which influence the distribution of plants; points out the countries and climates which different families affect; and gives us principles for their cultivation, either as medicines, or as objects of agriculture: the other is no less valuable in affording us innumerable indications in every part of the world, for discovering the properties of new and unknown plants, whether as fitting them for food, for medicine, or for any of the arts of life[.]” [Royle, p. 3]

Cinchona, a South American genus. Its bark contains medicinal compounds including quinine, used to treat malaria. Royle recommended that Cinchona be grown in India.

Cushing/Whitney Medical Library of Yale University

The copy of Royle’s text in BHL belonged to Edward Salisbury, a Yale graduate and professor who encouraged scholarship on West and South Asia. Salisbury donated his “Oriental Library,” a collection of hundreds of rare and early printed books and manuscripts, to the college in 1870. Salisbury’s Oriental Library is foundational to what is now the third-largest collection of Islamic manuscripts in the United States. Last year, Yale celebrated Salisbury’s 175th anniversary as the first professor of Arabic and Sanskrit languages and literature in the Americas.

Essay on the antiquity of Hindoo medicine is now held at the Medical Historical Library of the Cushing/Whitney Medical Library. The library was named for Yale graduates Harvey Cushing, known as the father of neurosurgery, and John Hay Whitney, Herald Tribune editor and patron of the arts. In 1935, Cushing and two other physicians, John F. Fulton and Arnold C. Klebs, donated their personal collections of medical texts to the medical library, beginning its Medical Historical Library. Its collections include materials ranging from the 16th to 20th century, with works from Robert Boyle, Galen, William Harvey, Hippocrates, and Andreas Vesalius. Additionally, the Historical Library also holds prints, a collection of weights and measures, and presents rotating exhibits.

The Cushing/Whitney Library is also home to the Cushing Center, a room in the stacks transformed to display the medical specimens of Cushing’s Brain Tumor Registry. Cushing meticulously documented over 2,200 case studies as he pioneered the field of neurosurgery, and his registry includes specimens preserved from human surgeries and autopsies as well as notes, journal excerpts, photos and negatives.

Medical Heritage Library

The Medical Heritage Library (MHL) is an online collection of materials that are free and openly accessible through the Internet Archive. Royle’s Essay on antiquity of Hindoo medicine came to BHL via the MHL.

Much like BHL, the MHL is a collaborative effort by medical libraries to promote access to resources (such as rare books, pamphlets, journals and films) that are useful across a spectrum of disciplines. The collection includes over 200,000 titles with fascinating variety – skimming the landing page, one can find herbals, medical dictionaries and papers, as well as video clips of 1960s tobacco commercials and Helen Keller’s autobiography.

The Medical Heritage Library was launched in 2010 by founders The Augustus C. Long Health Sciences Library at Columbia University and Columbia University Libraries/Information Services; The College of Physicians of Philadelphia; The Cushing/Whitney Medical Library at Yale University; The Francis A. Countway Library of Medicine at Harvard University; U.S. National Library of Medicine; and Wellcome Library in London, UK. (For more information about its content contributors, funding and support, please see MHL’s ‘About’ page.)

An essay on the antiquity of Hindoo Medicine is a welcome addition to BHL’s collection of works by John Forbes Royle, which include:

• Illustrations of the botany and other branches of the natural history of the Himalayan Mountains: and of the flora of Cashmere. London: Wm. H. Allen, 1839. (Digitized by Missouri Botanical Garden)
• On the culture and commerce of cotton in India and elsewhere; with an account of the experiments made by the Hon. East India Company up to the present time. London: Smith, Elder, 1851. (Digitized by the University of British Columbia Library)
