In Port-Vila and Luganville—Vanuatu’s two largest cities—most people live in buildings that are made in much the same way as those found in New York, Paris, or Sydney. But across most of Vanuatu, the great majority of people still live in small villages, and it is in these areas that we see the wisdom of traditional approaches to building houses. The advantages of these techniques—and the potential lessons for other areas that suffer increasingly from severe tropical weather—may be especially timely in light of Hurricane Florence, which has buffeted North and South Carolina with high winds and heavy rains.

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.

As part of The New York Botanical Garden’s ongoing project to document all of the plant life of New York City, the Botanical Garden’s Center for Conservation Strategy recently issued a new report, State of New York City’s Plants 2018, the first in what is envisioned as an annual overview of the status of the city’s spontaneous plant species—that is, native plants and non-native plants that have become established in the five boroughs.
The report, which was released at NYBG’s First Annual EcoFlora Conference, found that 2,029 plant species have been reported in New York City from 1807 to 2018. The most species-rich families are the grasses, daisies, and sedges.
At the other end of the spectrum are rare and endangered plants. The International Union for Conservation of Nature, which tracks threatened and endangered plant and animal species, ranks six New York City plant species as critically endangered worldwide, including four species of ash trees, the American chestnut tree, and Bayard’s Adder’s-Mouth orchid. Adding in New York City species that are considered rare, threatened, endangered or extinct by the U. S. government and New York State, some 13 percent of the city’s flora is imperiled or has gone extinct.

One of the highlights of summer at The New York Botanical Garden is the annual Cullman Intern Lunch, celebrating the diligent efforts and bright potential of the high school, college, and graduate students who work with Botanical Garden scientists studying the DNA and genomes of plants to understand their evolution and development.
Messages from the Gods: A Guide to the Useful Plants of Belize, by NYBG’s Michael Balick, Ph.D., and Rosita Arvigo, D.N., is the winner of the 2018 Mary W. Klinger Book Award, which is given annually to an outstanding book in the fields of economic botany and ethnobotany.
The culmination of a research project that began in 1987, Messages from the Gods is both a cultural study and a specialized field guide, with information about native and introduced plants in Belize and their traditional and contemporary uses as sources of food, medicine, and fiber and in spiritual practices, among many other purposes. The Society of Economic Botany—the preeminent professional association of researchers who study the relationships among plants, people, and culture, which presents the annual Klinger award—recognized the book as a definitive resource with a breadth and depth of knowledge “that will serve as a primary source on the plants of Belize and their uses for many generations.”
“This book is a truly significant volume that culminates decades of close collaboration between the two authors and local experts in Belize who practice and teach plant-based medicine and crafts and who promote the conservation and appreciation of that country’s diverse array of plant species, ecosystems, and human communities,” said Gayle Fritz, Ph.D., the President of the Society for the last year.
Messages from the Gods was co-published by The New York Botanical Garden and Oxford University Press.

Editor’s Note: As the end of the academic year approaches, The New York Botanical Garden’s Plant Science and Conservation program will soon welcome a new class of summer interns. As described in this post, these internships offer valuable experience by allowing students to work closely with NYBG scientists on cutting-edge research.
I spent last summer and fall as an intern working with Vice President and Cullman Curator Dennis Stevenson, Ph.D., on the Gymnosperm Seed Evolution Project at The New York Botanical Garden. The goal of this project is to better understand the relationships among different gymnosperms based on their seeds and seed-bearing organs. My work focused on the anatomy of early phases of ovule development, with an emphasis on branching of the vascular bundles, which contain the specialized cells that transport water and nutrients throughout the plant. I used an anatomical approach because my work involved comparing extant and extinct cycads. Although we cannot extract DNA from the fossils, we can look for structural features in both the fossils and extant species in order to place our fossils on a phylogeny (evolutionary tree) and establish a minimum age for cycads.

Representatives of The New York Botanical Garden and JetBlue Airways launched their new Caribbean Consortium at a recent meeting at the Botanical Garden’s Pfizer Plant Research Laboratory. The consortium, which was announced in February, will address the linked issues of conservation and commerce across the Caribbean, a vital part of JetBlue’s network and a longtime focus of the Garden’s Plant Research and Conservation program.
With the goal of striking a balance between conservation and commerce, the consortium will bring together a cross-section of key stakeholders from business, academia, and non-governmental organizations, such as the Center for International Policy, a Washington, D.C., foreign policy research and advocacy group, whose Cuban program director, Elizabeth Newhouse, participated in the meeting. Also joining was Robert Muse, a Washington attorney who has worked on Cuban issues since the early 1990s.
“This partnership with JetBlue is going to help translate conservation research into conservation action,” said Brian Boom, Ph.D., the Garden’s Vice President for Conservation Strategy, who has traveled to Cuba regularly since 1988 to conduct research and build relationships with his Cuban counterparts.

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.
