The concept of a “living fossil” was first proposed by Darwin in his book On the Origin of Species in 1859. The term “living fossil” is used to describe species that have managed to remain physically identical over the course of millennia and are still alive today. As these species have survived a wide range of extreme environmental conditions, including several mass extinctions, they beg the question: how have the living fossils been able to persist over millions of years? Scientists at The New York Botanical Garden believe the answer may be found in the living fossils of the plant kingdom. Most of these “living fossil” plant species are in the cone-bearing, non-flowering group of plants, called gymnosperms. Gymnosperms have very large and complex genomes, some being almost seven times the size of a human genome. Decoding the genomes of these species may give us some clues as to understanding their resilience over time.
The most widely recognized living fossil of the plant kingdom is Ginkgo biloba. It is easily recognizable by its distinct fan shape leaves that resemble those of the maidenhair fern (Adiantum capillus-veneris), giving it the common name of maidenhair tree. Ginkgo has remained unchanged for over 280 million years, surviving several glaciation events, fluctuations of carbon dioxide concentration and temperature, and mass extinctions. Because of its resilience, it is often seen lining city streets, including the streets that border The New York Botanical Garden.
Sitio Roberto Burle Marx, the eponymously named home of the iconic Brazilian landscape architect, was a haven of native Brazilian plants, from tropical bromeliads and philodendrons to orchids, legume trees, and more—many that he discovered himself. Discover just a few of the Brazilian specimens from the NYBG Herbarium that called the Sitio home, some even named for Burle Marx, in the latest from The Hand Lens.
From the Peggy Rockefeller Rose Garden to our Steere Herbarium, Rosa ‘Home Run’ transitions between two forms of beauty. Swipe through to see the preserved form of this vivid red rose, as well as other roses from among the 7.8 million cataloged specimens in our Herbarium which have a profound influence on our understanding of biodiversity, as we approach the spectacle of the Rose Garden’s peak spring bloom in 2019.

The New York Botanical Garden is currently digitizing all of its herbarium specimens from the Southern Rocky Mountains, a major subregion of the Rockies that runs from southern Wyoming through Colorado to northern New Mexico and eastern Utah.
Dolly Parton isn’t the only public figure to have a new species of lichen named after her by NYBG scientists. Following precedent in naming discoveries after incredible American women, we can now add Oprah Winfrey to the list.

With their exotic flowers and lush foliage, orchids are often considered the quintessential tropical plant, but as a recent publication from NYBG Press demonstrates, they are also native to the northeastern United States. Orchids (or Orchidaceae, their scientific name) are among the 27 plant families that are now available in the third installment of treatments released as part of the New Manual of Vascular Plants of Northeastern United States and Adjacent Canada by Robert F. C. Naczi, Ph.D., NYBG’s Arthur J. Cronquist Curator of North American Botany, and Collaborators. The family treatments have been published as individual, downloadable PDFs that can be viewed on a variety of devices such as a desktop computer, tablet, or smartphone.
In the region covered by the New Manual, there are 84 species of orchids, according to the treatment by Matthew C. Pace, Ph.D., Assistant Curator of the William and Lynda Steere Herbarium at The New York Botanical Garden, and John V. Freudenstein, Ph.D., Professor of Evolution, Ecology, and Organismal Biology at The Ohio State University.

Intriguing and ethereal, Indian pipes (Monotropa uniflora) are often mistaken for fungi because of their pale, otherworldly appearance. Also known as ghost plants, they typically occur in well-established forests and are often thought of as indicators of healthy ecosystems—not the kind of plant you might think would grow in a dense urban area. However, pockets of preserved forests in New York City, such as the old-growth Thain Family Forest at The New York Botanical Garden, can allow species to flourish in unexpected places.
I came to the heart of the Bronx recently to hunt for Indian pipes in the Thain Forest as part of the research I am conducting for my master’s thesis at The Ohio State University.
These fascinating parasitic plants have been the subject of much interest over the years, including research by an early 20th Century NYBG scientist. Indian pipes are unusual in that they do not photosynthesize. Instead, they are mycoheterotrophic, meaning they obtain nutrients by parasitizing a type of fungi that associate with plant roots. These mycorrhizal fungi help the plants take up water and nutrients that might otherwise be inaccessible to the plants. In exchange, the plants provide the fungi with sugars created from the process of photosynthesis. Indian pipes take advantage of the relationship between another plant and its associated fungus and “steal” sugars from the fungus. This three-part symbiosis allows Indian pipes to ultimately get their nutrients from a photosynthetic plant through the means of a mycorrhizal fungi.

One of the most pressing challenges in botany today is inspiring and training the next generation of systematists, scientists who discover, name, and classify species. In January, an international partnership sought to address this need through a tropical field botany course held in Ecuador for eight graduate students. The program was designed to engage students first-hand with the exciting (and sometimes trying) nature of field collection that is foundational to systematics.
The course was organized by Gregory M. Plunkett, Ph.D., Director and Curator of the Cullman Program for Molecular Systematics at The New York Botanical Garden; Porter P. Lowry II, Ph.D., and M. Marcela Mora, Ph.D., of the Missouri Botanical Garden; and David A. Neill, Ph.D., of Universidad Estatal Amazónica (UEA) in Ecuador with help from Efrén Merino. Of the eight students, four were from the United States and four from Ecuador. They came together at the UEA field station called Centro de Investigación Posgrado y Conservación Amazónica (CIPCA) to learn the logistics of botanical field work, using the genus Schefflera (in the Araliaceae family) as an example. The students brought with them a variety of backgrounds and interests, including plant-insect interactions, lichenology, and conservation, but were eager to get their feet wet in tropical field botany.

For most of us, calendars rule our lives. They allow us to organize our days, remind us of future appointments, and importantly, help us to carve out a space when we can take a break from the frenetic pace of life. Increasingly, they are stored on our computers or mobile phones, but this modern tool developed and evolved over a long period of human history.
Before the introduction of the Western calendar, people in Vanuatu reckoned time through their own observations of the natural world. Especially important were certain species of “calendar plants,” whose flowering or fruiting provided an indication of the change of seasons and cues for certain activities, such as gardening, hunting, and fishing. The use of plants as a guide for human activities is of great interest to us. During the past two years, we have been privileged to work with a team of people focused on understanding the diversity, distribution, uses, linguistics and conservation of the Vanuatu flora. Our work on the Tafean islands of Tanna and Aneityum involves collecting plants, mapping plant distributions, and gathering information on the local names of these plants and how people use them.
Alexander Hamilton considered himself a poor gardener.
In December 1802, he conveyed this fact to a friend in the most pointed way he knew how—via a political dig at President Thomas Jefferson, his longtime rival. Hamilton quipped that horticulture was a pursuit “for which I am as little fitted as Jefferson to guide the helm of the U[nited] States.”
When Hamilton wrote these words, he was facing an entirely novel challenge: laying out the grounds of his new country house in northern Manhattan. The Grange, as he called it, was a boxy yellow mansion on a parcel of about 35 acres he had purchased in 1800. From its piazzas, Alexander and Eliza could catch glimpses of the Hudson, East, and Harlem Rivers.
