Carnivorous plants, beguiling vegetables capable of attracting, trapping, and digesting animal prey, have fascinated generations of botanists on nearly every continent. However, there is perhaps no better way to trace their rise to cultural prominence than through the eyes of the Darwin family. The botanical legacy of Charles Darwin, his grandfather Erasmus, and son Francis, conveys the dramatic shift in how carnivorous plants were perceived by general botanical audiences from the late eighteenth century and into the twentieth. From poetic musings about their carnivorous habits to pulp fiction accounts of man-eating vegetal monsters, the BHL carnivorous plant collection offers a glimpse into the powerful spell these plants have cast over readers and observers through the centuries.

Charles Darwin was enamoured with carnivorous plants. As early as 1859, soon after encountering the sundew Drosera rotundifolia on an English heath, the author of On the Origin of Species wrote, “I care more about Drosera than the origin of all the species in the world” (Darwin Correspondence Project). By September 1860 he was working with Dionaea muscipula as well, and would later dub the Venus flytrap “one of the most wonderful” plants in the world (Darwin 1875, 286). Darwin’s rigorous experimentation with these enigmatic vegetal carnivores culminated in 1875 with the publication of Insectivorous Plants. This treatise laid the framework for the study of plant carnivory as it exists today and cemented the notion of carnivorous plants in the scientific and public imagination.

In a world where staggering habitat destruction and biodiversity loss have become the new normal, understanding the extraordinary interactions between plants and humans is increasingly urgent. Yet the human tendency to ignore the importance of plant-human interactions remains persistent. The Plant Humanities Initiative at Dumbarton Oaks seeks to address this gap in plant awareness through an interdisciplinary coalition of programs and scholarship tackling the cultural significance of plants in human affairs.

As the Digital Plant Humanities Intern for Dumbarton Oaks this summer, I will be writing an interactive, visual essay on the cultural history of Venus flytrap (Dionaea muscipula) for the Plant Humanities Lab – a new open access portal developed by Dumbarton Oaks and JSTOR Labs. Accompanying this essay is a BHL collection highlighting the wealth of digitized scientific literature and botanical illustration surrounding carnivorous plants. These fascinating organisms attract, capture, and digest animal prey in order to supplement the nutrient-poor soil of their natural habitats. Today, over seven hundred species possessing this specialized suite of adaptations have been identified, evolving at least seven times independently!

Plant species worldwide face an increasing barrage of threats to their survival. The deliberate collection of rare plants poses a far greater threat to wild plant species. In Wild Plants in Trade (1992), the reasons and effects of wild collection on plants for cultivation and international trade can be found. The trade of orchids, bulbs, cycads, palms and tree ferns, cacti and other succulent plants, carnivorous plants and air plants were introduced in detail in the second half of this book, as well as the attempts to control the collection of these plants by the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) and governments.

By the time this post publishes, the vast majority of Brood X (2021) will have completed their above ground lifecycle. The vast numbers of adult Magicicada who first emerged in late April and early May will have disappeared, leaving behind their adult bodies as well as still massive numbers of exuviae (cast-off outer skins) from when they emerged as nymphs.

Three hundred and seventy-four years ago on 2 April 1647, a remarkable woman was born: the artist and naturalist Maria Sibylla Merian. In the 17^th and 18^th century world of male-dominated science, Merian had to fight for her place in the natural sciences. Against all odds, she became a trailblazer, especially in developmental biology.

Merian’s legacy was recently explored during a 4-week student-project at the library of the Museum für Naturkunde in Berlin. The project was part of a master’s program for the University of Applied Science in Leipzig to enlarge the student’s experience in the historical holding field and give a glimpse into the planning and conducting of a project. The aim of the project itself was and is the digitization of two different editions of Merian’s work Metamorphosis insectorum Surinamensium as well as a restorative and provenance research summary about the volumes. Both editions show Merian’s talent in painting and observing insects and plants.

In preparation for Asian American Pacific Islander Heritage Month, I chose to reflect on the intersections of my past and present work in Biodiversity Heritage Library (BHL) collections, with historical connections to my home in Hawaiʻi. Part of my primary duties as a Conservation Technician with the Smithsonian Libraries and Archives is to stabilize objects before and after digitization for BHL. When I joined the team in 2018, I was assigned the task of mending the library’s 4 volumes of the 1853 edition of William Ellis’ Polynesian Researches During a Residence of Nearly Eight Years in the Society and Sandwich Islands. The idea was to kick off my new job with a project that would inspire me on a personal level, as an introduction to the value of both the digital and physical preservation responsibilities of our institution.

On 10 May, I had my first sighting of this year’s periodical cicada in Northern Virginia. For seventeen years, three species of Magicicada, the periodical cicada (M. septendecim, M. cassinii, M. septendecula)[1] have been living about 61 cm (2 feet) underground beneath trees across portions of eastern North America. In May 2021, individuals in Brood X (sometimes known as the Great Eastern Brood) began to emerge in the trillions from their long sojourn when soil temperature reached a consistent temperature of 18 degrees C (64 degrees F) or higher.

The last time Brood X emerged was in 2004. For those who witnessed that appearance, or previous ones, Brood X at times feels like a science fiction movie with the creatures swarming and the loud (up to 90 decibel) mating song of the males drowning out conversations (I wonder how the rest of the world will react to our Zoom call being joined by singing cicadas!).

Magicicada are mostly harmless, neither biting nor stinging. Members of the order Hemiptera, the nymphs spend their underground life harmlessly consuming xylem fluids from the roots of deciduous forest trees; the adult female, which deposits its eggs in small slits cut into the ends of branches, rarely causes damage to mature trees and there is speculation that the cicada pruning leads to more abundant leafing and fruiting the following year.
