Neoblechnum brasiliense (Blechnaceae) is common and widespread in South America but has been known from Mesoamerica by only one collection from Guatemala by Julian Steyermark in 1939. We discovered two new occurrences of the species, in Belize and Mexico, extending the range of the species over 1000 km north and west into northern Mesoamerica. We discuss possible explanations for the rarity of the species in Mesoamerica and its disjunction from South America.

巴西矮树蕨的奇怪分布，巴西新白草（Blechnaceae）：新的国家记录和显着的范围扩展

Neoblechnum brasiliense（Blechnaceae）在南美洲很常见且分布广泛，但在 1939 年 Julian Steyermark 从危地马拉的一个收藏品中发现中美洲。我们在伯利兹和墨西哥发现了该物种的两个新物种，扩大了该物种的范围北部和西部超过 1000 公里，进入中美洲北部。我们讨论了该物种在中美洲的稀有性及其与南美洲的分离的可能解释。
