general taxon notes:
Schroeterella is a neotropical genus with two species (Câmara & Carvalho-Silva 2013). The sporophyte characters that distinguish Schroeterella and appear to be unique to the genus are: exostomial teeth 8-paired with acute rounded tips, reflexed when dry, and endostome represented solely by narrow cilia about 2/3 the length of the exostome; the alar cells are also distinctive, obliquely arranged similar to Acroporium. The generic name honors, according to Herzog, “Dr. C. Schröter, Professor de Botanik an der Eidgenöss. Technischen Hochschule in Zürich.”
 
Schroeterella es un género neotropical de dos especies (Câmara & Carvalho-Silva 2013). Las características del esporofito diferencian a Schroeterella y parecen ser únicas en este género, 8-pares de dientes del exostoma con extremos redondeados agudos, reflexo cuando seco, y endostoma representado sólo por cílios angostos ca. 2/3 de la longitud del exostoma; también células alares están ordenadas oblicuamente. El nombre genérico, según Herzog honra a, “Dr. C. Schröter, Professor de Botanik an der Eidgenöss. Technischen Hochschule in Zürich.”
