During World War II part of the material stored at the herbarium of the Natural History Museum Vienna (W) was destroyed by fire, including the majority of the Bromeliaceae collection and some types of Bromelia names. In the cases of B. poeppigii and B. reversacantha original material accompanied by anatomical drawings relevant for the delimitation of the species has now been discovered at the herbarium of the Botanic Garden and Botanical Museum Berlin-Dahlem (B). Lectotypes are designated and, in the case of B. reversacantha, an epitype is selected.
