Scientific names get chosen for lots of reasons-- they can honor an important person, or hint at what an organism looks like or where it’s from. For a tropical wildflower first described by Smithsonian Botanist Laurence Skog and his colleague Lars Kvist in 2000, the scientific name “extinctus” was a warning. The orange wildflower had been found 15 years earlier in an Ecuadorian forest that had since been largely destroyed; Skog and Kvist suspected that by the time they named the species, it was already extinct (Syst. Bot. Monogr. 59: 1-118; 2000; https://doi.org/10.2307/25027883). But in a new paper in PhytoKeys (https://doi.org/10.3897/phytokeys.194.79638), researchers report the first confirmed sightings of Gasteranthus extinctus in 40 years.

“Extinctus was given its striking name in light of the extensive deforestation in western Ecuador,” says Dawson White, a postdoctoral researcher at Chicago’s Field Museum and co-lead author of the paper. “But if you claim something's gone, then no one is really going to go out and look for it anymore. There are still a lot of important species that are still out there, even though overall, we're in this age of extinction.”

Botanical data for all: The U.S. National Herbarium is digitized! [Video]

From Plant Press, Vol. 25, No. 3, July 2022.

By Sylvia Orli and Julia Beros.

The breadth of collections held at the U.S. National Herbarium (USNH) document the incredible biodiversity and botanical heritage on our planet and serve as the backbone of our work. In service to the public and as the foundation for research, these collections, as they exist now and grow, are at the core of our mission and purpose as an institution. Making these assets available, in physical and digital form, is a fundamental part of fulfilling our responsibility. The USNH is one of the world’s largest and most diverse botanical collections, accounting for nearly 5 million specimens, the digitization of which fulfills our goal to make specimen data and images discoverable and accessible to all.

Since 2015, the Department of Botany and the Smithsonian Digitization Program Office (DPO) have embarked on a joint project to digitize all pressed and packeted plant specimens, which comprise the great majority of our collections. Collaborating with the contracted digitization company Picturae, based in the Netherlands, we have employed a conveyor belt system and a high-throughput approach to realize this ambition. This approach to digitization provides high resolution images and transcriptions of label data for each specimen. These assets are ported to our data catalog and subsequently aggregated with global collections data from other herbaria. By these means, the digitization of the USNH has a huge impact on botanical research throughout the world—collecting and codifying data that can unexpectedly inform the work of researchers near and far.

Since 2004 he has been a curator in the Institute of Systematic Botany at the New York Botanical Garden (NYBG) where he continues his research on Melastomataceae. With about 177 genera and 5,800 species, Melastomataceae is one of the most easily recognized tropical plant families and the Smithsonian and NYBG have some of the world's best collections due to multiple generations of curator research on the family.

An exceptional symposium explores plants on the edge [Video]

From Plant Press, Vol. 25, No. 3, July 2022.

The 19^th Smithsonian Botanical Symposium, co-hosted by the Smithsonian’s Department of Botany and the United States Botanic Garden (USBG), made a welcome return to the National Museum of Natural History’s (NMNH) Baird Auditorium on May 13, 2022, three years after the last time the event was held in person. The Symposium, “Life on the Edge: Exceptional Plants in Exceptional Places,” was a hybrid event, bringing together five engaging speakers to present their research to both in-person and virtual audiences from around the world. The invited speakers included scientists specializing in conservation, ecology, systematics, and genetics whose research explores plant adaptation and survival in extreme parts of the natural world. The speakers talked about their research on plants (and lichens) growing in exceptional environments, from the tepuis of the Guayana Shield and the steep cliffs of Hawaii to the South African Fynbos, the Mojave Desert, and even New York City. They spoke about natural history and evolution, and the challenges plants endure in the face of climate change and increasing pollution.

Eric Schuettpelz, NMNH Chair of Botany, welcomed the audience to the symposium and Rebecca Johnson, NMNH Associate Director for Science and Chief Scientist, provided opening remarks. In her comments, Johnson talked about a project, “Life on a Sustainable Planet,” currently in development at NMNH, and she tied the project to the theme of the symposium. She described the new project as, “understanding, explaining, and amplifying the reach, relevance, and impact of the work here at the Smithsonian,” and the relevance to the tens of thousands of species 'on the edge'. Susan Pell, USBG Deputy Executive Director, also provided opening remarks and gave an orientation to the USBG, including a description of the living collections, current online and in-person programming, and their scientific and conservation partnerships.

Behind-the-scenes video takes you inside the Botany Digitization Conveyor project [video]

From Plant Press, Vol. 24, No. 4, October 2021.

A behind-the-scenes video of the Botany Digitization Conveyor project is now available on YouTube  where you can see the conveyor belt in action and hear about the workflows and processes that made the project such a success. After 6 years of digitizing the US National Herbarium, the digitization project is nearly complete. By January 2022, nearly 4 million catalog records of the herbarium’s botanical specimens will have been digitized, each with a high-resolution image. All flowering plants and ferns, lichens, bryophytes, and algae will be represented online (see the online collection portal). 

The behind-the-scenes video was featured during the “Biodiversity Digitization: A Decade of Success” (Biodiversity Digitization 2021 | iDigBio) virtual conference. Co-sponsored by the National Museum of Natural History (NMNH), iDigBio, and GBiF, the two-day conference held on September 22 and 23 celebrated the collective successes of mobilization and efforts to digitize the world’s biodiversity data in the US and abroad. Participation by NMNH staff in the conference included six speakers and four virtual tours of the museum’s collections. Over 800 attendees pre-registered for this event.

The virtual conference provided both detailed looks at specific work being done in digitization, as well as a broad outlook on the meaning and significance of digitized collections. The themes for the two-day conference were innovations, community, grand challenges, what’s next, and looking to the future of digitization.

Other behind-the-scenes tours featured at the conference include those of the Entomology Collection, Molluscs Collection, and Cultural Objects. Each video is part of NMNH’s “Natural History for Scientists” YouTube channel.

Research & Activities [Video]

From Plant Press, Vol. 24, No. 3, July 2021.

On May 19, Research Associate John Wiersema presented a webinar entitled, “A Taxonomist’s View on the Essence of Waterlilies that Inspired Claude Monet,” to the membership of Marie Selby Botanical Garden in Sarasota, Florida. In this virtual botanical briefing, Wiersema asked, “What is it about the nature of waterlilies that provided the inspiration for Claude Monet’s gardens and so many of his impressionist paintings?” Wiersema’s webinar examined the role of waterlilies in the aquatic landscape, explored the relationships among the various forms of waterlilies throughout the world, and probed the aesthetic qualities that have made them the ultimate aquatic ornamental. He also spoke about the early history of waterlily hybridization in Europe in relation to the waterlilies available to Monet when Monet established his water garden in Giverny in the late 19th century, with a closer look at those that successfully established on Monet’s estate. Wiersema also finds an appreciation in the sheer beauty and serenity of pristine waterlily settings and a Monet impressionist rendering of it.

In John Wiersema's webinar, "A Taxonomist’s View on the Essence of Waterlilies that Inspired Claude Monet," Wiersema provides a chronology of Monet's paintings and looks closely at the botany behind the artist's inspiration.

Wiersema, a specialist on the taxonomy of the waterlily group, focuses his research on the waterlily genus Nymphaea. He has studied and collected these plants in both temperate and tropical countries on six continents, personally cultivating at least 60 such gatherings for direct observation over the last four decades, and examined thousands of global water lily herbarium specimens. He has discovered and described several new species and has participated in over 30 scientific publications on the group. Retired from the U.S. Department of Agriculture’s Agricultural Research Service after more than 30 years, he now serves as a Research Associate in the Botany Department of the Smithsonian Institution’s National Museum of Natural History. Wiersema gained global standing as a specialist in plant nomenclature, and now has direct editorial involvement with both the botanical and cultivated plant codes of international nomenclature and the international journal Taxon. Over his professional career, he has contributed to some 125 scientific publications.

The discovery, they say, is the fruit of extensive fieldwork across northeast India and rigorous sifting through plant specimens in herbariums across the world.

The new plant species sheds some light on the unique evolutionary trajectory of flora in the northeastern parts of India. Such findings, the researchers say, are important in designing conservation approaches to protect the fragile ecosystems of northeast India.

Named after the late botanist Vicki Ann Funk from the Smithsonian National Museum of Natural History (NMNH), the plant (Didymocarpus vickifunkiae) is an endangered species that currently grows in three districts of Mizoram. It grows on moss-covered trees and blooms light pink flowers during the monsoons.

The 18^th Smithsonian Botanical Symposium, co-hosted by the Smithsonian’s Department of Botany and the United States Botanic Garden, was held virtually over two days on May 13 and 14, 2021. The Symposium, “Plant symbiosis: The good, the bad, and the complicated,” was originally scheduled to take place in May 2020 at the National Museum of Natural History (NMNH) in Washington, DC, but the coronavirus global pandemic pushed the symposium to 2021. The digital event this year successfully brought together six engaging speakers in a Zoom webinar setting to explore current research in the diversity of plant symbioses, examining the relationships plants have with insects, fungi, bacteria, and even other plants. Invited speakers included botanists, ecologists, microbiologists, and geneticists whose research unravels the complicated relationships that plants have with their collaborators and competitors in the natural world.

Rebecca Johnson delivers opening remarks and spoke about the museum’s strong relationship with the U.S. Botanic Garden and our shared mission to educate the public about plants.

Eric Schuettpelz, Chair of Botany at NMNH, welcomed the virtual audience to the symposium and Rebecca Johnson, Associate Director for Science and Chief Scientist at NMNH, provided opening remarks.
