Notes. – This species is found in southeastern Brazil and northern Paraguay ( TAYLOR, 2005). TAYLOR (2005) reported the place of deposit of the holotype of Mapouria cymuligera at M, but the specimen at BR with an annotation in Müller’s hand appears to be the actual holotype. Another of M. cymuligera isotype was formerly deposited at B but has been destroyed (photo F neg. #25701). The identity of M. umbelluligera has not been clear until recently. Its type matches that of M. cymuligera , and in fact their types have sometimes been confused (e.g., K [K000174275], P [P02285220]). These names were published simultaneously; the name M. cymuligera has been used more often and is chosen here. The duplicate of the type collection of M. umbelluligera in Müller’s herbarium at G was annotated with this name by him and has both flowers and fruits, and this is presumed to be the holotype. One other duplicate has an annotation in Müller’s handwriting (BR [BR0000008259974]), and is deposited at BR and has ample material and complete label data. This BR specimen is labelled as being originally deposited at BR and not part of the Martius herbarium, and therefore is an isotype. The other duplicate at BR was originally deposited there, was unidentified until the 20th century, and lacks flowers.

See TAYLOR (2005) for synonymy, except ZAPPI (2003) showed that the type of Mapouria xanthophylloides Müll. Arg. belongs to Rudgea coronata subsp. ochroleuca (Müll. Arg.) Zappi.
