Cytology
[edit]The diploid chromosome count is 2n = 46.[8]
Taxonomy
[edit]It was published by Hamilton Paul Traub in 1957 with Rauhia peruviana Traub as the type species.[2]
Species
[edit]As of June 2023[update], Plants of the World Online accepted the following species:[1]
- Rauhia albescens Meerow & Sagást.
- Rauhia decora Ravenna - Peru (Amazonas)
- Rauhia multiflora (Kunth) Ravenna - Peru (Cajamarca)
- Rauhia occidentalis Ravenna - Peru (Cajamarca)
