Peucedanum

Peucedanum is a genus of flowering plant in the carrot family, Apiaceae.^[3] Peucedanum boasts a global presence with diverse spread of morphological features.^[4][5] Peucedanum species are characterized by dorsally compressed mericarps, slightly prominent dorsal ribs, narrowly winged lateral ribs, and a broad commissure.^[5] However, the vast diversity of morphology, fruit forms, and phytochemical production makes classifying species in the Peucedanum challenging.^[6][5] Historically relevant in traditional medicine, Peucedanum's taxonomic complexity arises from its extensive diversity.^[7][5]

Peucedanum's taxonomy is being reshaped by novel genomic insights, prompting ongoing revisions with promising implications for ethnopharmacological research and the broader understanding of plant biodiversity.^[5] These efforts hold potential for advancements in therapeutic discoveries and contribute to the ecological significance of this globally diverse genus.

Taxonomy

Recent genomic analyses have indicated Peucedanum's non-monophyletic nature, prompting revisions in its taxonomic classification.^[5] Once considered among the largest genera of the Apiaceae, taxonomic revisions, informed by genomic and phytochemical analyses, have reduced the estimated number of Peucedanum species to approximately 74.^[5][4] Molecular phylogenetic studies have identified fifteen mutation hotspots in the Peucedanum genome, providing potential markers for accurate species classification.^[5] Ongoing taxonomic revisions, guided by genetic insights, aim to enhance accuracy and facilitate the discovery of new Peucedanum species.

Distribution

Spanning from Madeira to the Hawaiian islands, Peucedanum's expansive geographical range has necessitated reclassification of African Peucedanoid species based on nuanced taxonomy incorporating genetic, morphological, habit, and seasonality considerations.^[4][30]

Medicinal potential

Peucedanum's medicinal significance, especially in treating antimicrobial-resistant infections, underscores the need for accurate taxonomy. Species like Peucedanum graveolens, Peucedanum japonicum, and Peucedanum ostruthium exhibit antimicrobial properties, suggesting potential as alternative treatments as a compliment to antibiotics in combating antibiotic-resistant pathogens.^[7][31][32]
