The distribution of intensities and the radius of the felt area indicate a magnitude around M w 6.9, which makes it the largest known earthquake in the stable continental region...

... ). In America only two species are reported, growing from the USA (the state of Florida) to the south of Brazil: Actinostachys pennula (Sw.) Hook. and A. subtrijuga (Mart.) C. Presl. The two species are very similar, and according to da Silva et al. ( 2015 ) they can be differentiated by the rectangular...
