Taxonomic characteristics of the Genus mucuna Adans. in Vietnam

The genus Mucuna Adans. encompasses around 105 species, predominantly inhabiting tropical and subtropical zones, with a significant number occurring in Asia. These species are mostly associated with primary and secondary forest habitats and are seldom cultivated, with M. pruriens being a notable exception. They are characterized as woody lianas, either annual or perennial-they exhibit considerable morphological variation. Mucuna species significantly contribute to forest ecosystem dynamics and offer diverse applications, including in timber production, traditional medicine, and food resources. Of these, two species are cultivated, while three are considered threatened and of conservation concern. This study provides a comprehensive account of the genus Mucuna in Vietnam, detailing its key morphological features, distribution patterns, habitat preferences, ecological functions, and practical applications. Additionally, a dichotomous identification key is proposed to aid in distinguishing the seven native species found in the flora of Vietnam.
