The "hidden diversity" of medicinal plants in northeastern Brazil: diagnosis and prospects for conservation and biological prospecting.

Cavalcanti DR, Albuquerque UP - Evid Based Complement Alternat Med (2013)

Bottom Line: Increases in ethnobotanical studies and knowledge in recent decades have led to a greater and more accurate interpretation of the overall patterns related to the use of medicinal plants, allowing for a clear identification of some ecological and cultural phenomena. "Hidden diversity" of medicinal plants refers in the present study to the existence of several species of medicinal plants known by the same vernacular name in a given region.Although this phenomenon has previously been observed in a localized and sporadic manner, its full dimensions have not yet been established.The results indicate that there are an average of at least 2.78 different species per cataloged ethnospecies in the region.

ABSTRACT
Increases in ethnobotanical studies and knowledge in recent decades have led to a greater and more accurate interpretation of the overall patterns related to the use of medicinal plants, allowing for a clear identification of some ecological and cultural phenomena. "Hidden diversity" of medicinal plants refers in the present study to the existence of several species of medicinal plants known by the same vernacular name in a given region. Although this phenomenon has previously been observed in a localized and sporadic manner, its full dimensions have not yet been established. In the present study, we sought to assess the hidden diversity of medicinal plants in northeastern Brazil based on the ethnospecies catalogued by local studies. The results indicate that there are an average of at least 2.78 different species per cataloged ethnospecies in the region. Phylogenetic proximity and its attendant morphological similarity favor the interchangeable use of these species, resulting in serious ecological and sanitary implications as well as a wide range of options for conservation and bioprospecting.

Mentions: Comparison of the data from the state of Pernambuco and the northeast region showed variation in the number of one-to-one correspondences that was inversely proportional to the size of the sampled area, whereas the number of homonym ethnospecies varied in proportion to the size of the sampled area, as shown in Figure 1. Consequently, the homonym ethnospecies predominated in the northeast (NE) sample (G = 48.41; df = 1; P < 0.00001).
