Societal Impact StatementAs herbaria digitize millions of plant specimens, ethnobotanical information associated with them is becoming increasingly accessible. These biocultural data include plant uses, names, and/or management practices of Indigenous Peoples and Local Communities (IPLCs). However, the absence of shared curatorial standards limits accessibility and use by IPLCs and others. We estimated and characterized ethnobotanical data associated with herbarium specimens and provide here key considerations for future work. We identified a proportionally small, yet collectively significant, number of ethnobotanical specimens, and call for coordinating best practices among global herbaria to locate, acknowledge, and responsibly share this information, together with source communities. SummaryAs herbaria digitize millions of plant specimens, those containing biocultural information are becoming increasingly accessible. This information — also known as ethnobotanical data — holds both cultural and scientific value, and may include plant uses, vernacular names, local species concepts, cultural values, and plant management practices of Indigenous Peoples and Local Communities (IPLCs). However, the lack of coordinated curatorial standards currently limits both the accessibility and effective use of this information by IPLCs, ethnobotanists, and others.To address this gap, we quantitatively estimated and characterized ethnobotanical information associated with herbarium specimens and offer key considerations to guide future work.We identified a proportionally small —yet collectively significant— number of ethnobotanical specimens, comprising approximately 1.6% of all specimen records and representing hundreds of thousands of specimens in the surveyed herbaria.We advocate for coordinating best practices to locate, acknowledge, and ethically share this information among herbaria, working together with source communities and through global cooperation. 

Recognizing species diversity is challenging in genera that display interspecific similarity and intraspecific variation; hybridization and the evolution of cryptic hybrid species amplifies these challenges. Recent molecular and morphological research focused on the systematics of Spiranthes (Orchidaceae) support hybrid speciation as an important driver of species diversity, particularly within the S. cernua species complex. Working under an integrated history-bound phylogenetic species concept, new molecular and morphometric data provide evidence for a new and rare cryptic hybrid species resulting from the ancient hybridization of S. cernua × S. odorata, here described as S. bightensis. Although S. bightensis is regionally sympatric with S. cernua it does not co-occur with that species, and it is allopatric with respect to S. odorata. Endemic to a narrow region extending from the Delmarva Peninsula to Long Island, New York, this new species occurs in the shadow of the Northeast megalopolis and appears to have undergone a major population decline over the last 200 years. By recognizing this distinct evolutionary lineage as a new species, this research is the first step towards developing conservation protocols for this rare species and highlights the importance of the North American Geologic Coastal Plain for biodiversity conservation and evolution.
