Species get described, then get cut down before science knows their names.
In the vanishing humid forests of Panama's Caribbean slope, scientists have given a formal name to a tree that local communities have long recognized — Scottmoria umbonata, a modest but ecologically significant species whose discovery arrives as the forests sheltering it face mounting pressure. Researchers from the University of Panama and the Smithsonian Institution published their findings in April 2026, adding one more entry to a catalog that grows even as the library itself burns. The discovery is both a testament to the depth of life still hidden in Sierra Llorona's biological corridors and a quiet alarm about how much may be lost before it is ever known.
- A tree known to local communities for generations has only now received its scientific name — a reminder that formal knowledge lags far behind living reality in the world's most biodiverse forests.
- Sierra Llorona sits at the crossroads of four major protected areas, yet its Caribbean lowland forests remain among the least studied in the region, leaving entire species invisible to conservation policy.
- Deforestation, new roads, hunting, and expanding settlements are fragmenting habitat at a pace that has already claimed newly described species shortly after their scientific documentation.
- Scottmoria umbonata persists in degraded pastureland thanks to its hard wood and resilience, but mere survival in a diminished landscape signals vulnerability, not security.
- The same research team has described multiple new Panamanian tree species in recent months, suggesting the country remains a frontier of botanical discovery — one that urgently needs protection to match its scientific promise.
In the humid forests of Panama's Caribbean slope, researchers have formally named a tree long known locally as coquito de potrero. Scottmoria umbonata was described by scientists from the University of Panama and the Smithsonian Institution's Tropical Research Institute, with findings published in Phytotaxa in April 2026. The species is distinguished by a pronounced central bulge on its fruit — the umbo that gives it its scientific name — and was carefully separated from its closest relative through months of comparative study of leaf structure, vein patterns, and reproductive traits.
The tree grows in Sierra Llorona, a region of Colón province that functions as a biological corridor linking Chagres, Portobelo, and Soberanía National Parks with Lake Gatún. These Caribbean lowland forests harbor unusually high numbers of species found nowhere else on Earth, yet remain relatively unexplored — which is why new species keep emerging from them. The same research team has described several other new tree species from Panama's cloud forests in recent months alone.
What shadows the discovery is the urgency of the threat. Sierra Llorona faces expanding settlements, new roads, logging, and hunting, all fragmenting habitat for species that may exist nowhere else. Some newly documented species have been felled shortly after their scientific description. Scottmoria umbonata survives in converted pastureland where primary forest once stood, its resilience allowing it to persist where others cannot — but persistence in a degraded landscape is not the same as flourishing in an intact one.
The tree is modest in form: three to ten meters tall, with gray peeling bark and a rounded crown, flowering from October through May. Its range is confined to a handful of localities in Colón's Costa Arriba region. That narrow distribution, set against accelerating habitat loss, means the species' future hinges on whether Sierra Llorona receives the conservation attention its ecological importance demands. The discovery is a celebration of Panama's scientific capacity — and a warning that many more species may be lost before science ever learns their names.
In the humid forests of Panama's Caribbean slope, researchers have just formally named a tree that local people have known for generations as coquito de potrero. The species, Scottmoria umbonata, was identified and described by scientists from the University of Panama and the Smithsonian Institution's Tropical Research Institute, with the findings published in the journal Phytotaxa in April 2026. The work represents another addition to the growing catalog of tropical plant life in Central America—and another reminder of how much remains hidden in forests that are rapidly disappearing.
The tree grows in the Sierra Llorona region of Colón province, in the lowland Caribbean forests that blanket the slopes above the coast. Juvenal Batista-Guerra and Juan Carrión from the University of Panama's Faculty of Natural, Exact and Technological Sciences, along with Ernesto Campos-Pineda from the Smithsonian, spent months comparing leaf structure, vein patterns, and reproductive characteristics to distinguish Scottmoria umbonata from its closest relative, Scottmoria woodsoniana. The distinguishing feature that gave the species its scientific name is a pronounced central bulge, or umbo, on the fruit—a trait visible from the earliest stages of development through maturity.
Sierra Llorona itself is no ordinary patch of forest. The region functions as a biological corridor connecting some of Panama's most important protected areas: Chagres National Park, Portobelo National Park, Soberanía National Park, and Lake Gatún. The forests here maintain ecological ties to South American ecosystems and harbor unusually high numbers of species found nowhere else on Earth. Yet these same Caribbean lowland forests remain relatively unexplored by international science, which is precisely why new species continue to emerge from them. In just the past few months, the same research team has described multiple new tree species from Panama's cloud forests, suggesting the country remains a wellspring of botanical discovery.
What makes the timing of this discovery urgent is the pressure bearing down on Sierra Llorona. The region faces expanding human settlements, new roads cutting through the forest, hunting, and logging—all fragmenting habitat for species that may exist nowhere else. The researchers note with concern that other newly documented species have been felled shortly after their scientific description. In communities like Santa Rita and Sierra Llorona, Scottmoria umbonata survives in converted pastureland where primary forest once stood, its hard wood and resistance to disturbance allowing it to persist where other species cannot. But survival in a degraded landscape is not the same as thriving in an intact one.
The tree itself is modest in stature—typically between three and ten meters tall, with trunks reaching thirty centimeters in diameter, a rounded crown, and gray, peeling bark. It flowers mainly from October through May, with fruit appearing between February and May and again in November. Its range is confined to specific localities: Sierra Llorona, Quebrada López, Quebrada Harina, and areas near Nueva Providencia and Santa Rita Arriba in the Costa Arriba region of Colón. This narrow distribution, combined with the habitat loss already underway, means the species' future depends on whether Sierra Llorona receives the conservation priority its ecological importance demands. The discovery, celebrated by the University of Panama as recognition of the country's scientific capacity, also serves as a warning: there are likely many more species in these forests waiting to be found—and many more at risk of being lost before science ever knows their names.

Why does it matter that this tree was already known to local people as coquito de potrero? Doesn't that diminish the discovery?
Not at all. Local knowledge and scientific documentation serve different purposes. The people of Santa Rita knew this tree worked—it survived where others didn't, its wood was useful, its seeds fed livestock. But that knowledge wasn't recorded in the global scientific literature, wasn't compared to related species, wasn't part of the international conversation about tropical biodiversity. Now it is.
The researchers seem worried about something beyond just cataloging a new species.
They are. They're watching a pattern: species get described, then get cut down. They mention other recently documented trees that were felled shortly after being published. There's a race happening, though not the kind usually celebrated. It's a race between discovery and destruction.
Sierra Llorona connects four major protected areas. Shouldn't that mean it's already safe?
Protected on paper and protected in practice are different things. The corridor exists, yes, but it's under pressure from settlements, roads, hunting, logging. Being important doesn't automatically mean being defended. The researchers are essentially saying: we just found this species here, and here's why this place matters—now please protect it before it's too late.
What does the umbo—that central bulge—actually tell us?
It's the key that unlocked the species' identity. Without that feature, Scottmoria umbonata would look very similar to Scottmoria woodsoniana. The umbo is consistent from fruit development to maturity, which made it a reliable marker for distinguishing one from the other. It's a small detail that turned out to be everything.
Is Panama unusual in producing this many new tree species discoveries?
Not unusual—exceptional. The country sits at a crossroads between North and South American ecosystems, packed into a narrow strip of land with extraordinary elevation changes and rainfall. That creates conditions for high endemism. And much of it has simply never been thoroughly studied by international science. That combination—biological richness plus scientific gaps—is why new species keep appearing.
