At a request from Jennifer Brundage (Smithsonian Affiliations), Alice Tangerini traveled to Northfield, Vermont on November 8-10, 2022, to present a lecture and display artwork at the Sullivan Museum. The Sullivan Museum at Norwich University is the only affiliate partner in the Northeast and had a current exhibition on one of their alumni, William Brenton Boggs. Boggs was on the North Pacific Exploring and Surveying Expedition and the U.S. National Herbarium has collections from that expedition. Tangerini’s talk, “Botanical Illustration, Then and Now,” included a history of illustration in publications mentioning the changes in media used and a synopsis of collecting specimens for herbaria, preparation of herbarium specimens, and illustration techniques. She included the story of the series of cactus illustrations made for the Whipple Pacific Railroad Survey of 1854 and how they were discovered in the herbarium. She emphasized the importance of keeping records of illustrations and how they add to our history in the sciences. The talk was well attended with an overflow in another room and recorded for later viewing. Tangerini brought full size copies of illustrations to the lecture and was able to have a small display of the Department of Botany’s Art Collection.

By Warren Wagner & Gary Krupnick

The National Museum of Natural History (NMNH) co-hosted a Hawaii Rare Plant Genetics Workshop from October 2021 to March 2022, featuring 32 speakers over the course of 10 virtual sessions. From those recorded sessions, 19 presentations are now publicly available for viewing as a playlist on NMNH’s Natural History for Scientists’ YouTube channel.

The goals of the 10-day workshop were to better understand how the latest molecular research, especially in the field of genomics, can benefit the ongoing challenges in plant conservation in Hawaii, and to determine when and how to incorporate molecular techniques into species recovery and management. Discussions centered around identifying particular techniques and methods most appropriate for a variety of questions and challenges regularly faced by field biologists in preventing species extinctions. One outcome of the workshop is that the workshop organizers are developing a decision tree for when and how best to utilize molecular techniques in plant conservation practices in Hawaii, and are creating a prioritization scheme that will allow field biologists to prioritize resources in funding and carrying out the highest priority research.

The workshop was part of a National Science Foundation (NSF)-funded collaborative project headed by Ann Sakai and Steve Weller (University of California, Irvine), Michael Moore (Oberlin College), Norm Wickett (Chicago Botanic Garden), and Warren Wagner (NMNH via National Tropical Botanical Garden) to capitalize on recent advances in molecular methods for the study of evolution and to allow for considerable enhanced detail of the evolution and conservation of Schiedea, one of the largest Hawaiian endemic lineages in the carnation family, Caryophyllaceae.

The central research goal of the funded proposal is to resolve the evolution of breeding systems in Schiedea, an extraordinarily diverse Hawaiian endemic lineage that serves as a natural laboratory of plant reproductive evolution, using a variety of field- and sequencing-based techniques. Schiedea is one of the most spectacularly diverse clades in any island plant group with respect to pollination and breeding systems, varying from insect to wind-pollinated species, hermaphroditic to dioecious breeding systems, and outcrossing to selfing mating systems.

Flowers of Schiedea have evolved a variety of ways to present nectar. Schiedea is the focal genus of an NSF-funded project employing a suite of high-throughput sequencing tools to better resolve the phylogeny and enhance understanding of trait evolution, especially related to breeding system diversity, which is among the highest exhibited in any island plant lineage. Schiedea has a unique nectary structure where each one has a shaft-like tubular extension that develops to varying extents. This nectary shaft is thin and translucent. Nectar fills the shaft and is extruded from the tip as a drop in species with elongate nectar shafts (A, S. lydgatei) or it forms in a pool on the surface of the sepal in species with recurved nectaries (B, S. verticillata). In the species likely bird pollinated the nectary is enlarged forming a nearly contiguous ring of nectariferous tissue. The abaxial margin of each nectary has a flap-like extension rather than a shaft. The black nectar produced in these species is usually copious and hexose-rich (C, S. obovata). Nectaries tend to be reduced in size in wind-pollinated species (D, S. adamantis). Figure reproduced from Wagner, et al. (2005).

Lost South American wildflower named “extinctus” rediscovered (but still endangered) [Video]

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

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.
