安达kiana Burmeistera和B. boyacensis被描述为主要来自哥伦比亚东部科迪勒拉的新种。第一种，与B. brachyandra和B. ramosa密切相关，生长在科迪勒拉山脉东部山坡的亚安第斯森林中，在caquet<e:1>和Putumayo省，有一些低地种群，是该属中唯一到达亚马逊森林的哥伦比亚物种。第二种是在东科迪勒拉山脉两侧的安第斯森林边缘采集的，与东方B. orientalis密切相关。对新种进行了说明，并讨论了它们之间的关系。这两个物种与它们的亲缘种有许多营养和生殖性状的不同，这些性状与茎的被毛、叶的结构和大小、花器官的形态和被毛以及果实的形状有关。我们建议将这两个物种视为极度濒危物种。
Burmeistera andakiana and B. boyacensis are described as new species primarily from the Eastern Cordillera of Colombia. The first species, closely related to B. brachyandra and B. ramosa, grows in sub-Andean forests at the eastern slopes of the Cordillera in the departments of Caquetá and Putumayo, with a few lowland populations, being the only Colombian species of the genus that reaches Amazonian forests. The second species, closely related to B. orientalis, has been collected at edges of Andean forests in both flanks of the Eastern Cordillera in the department of Boyacá. The new species are illustrated and their relationships are discussed. Both species differ from their relatives by a number of vegetative and reproductive traits related to the indumentum of the stem, the architecture and size of leaves, the morphology and indumentum of floral organs, and the shape of the fruits. We suggest that both species be considered as critically endangered.
