Abstract

The identity ofBlandibractea (based solely on flowering material) has never been questioned, and it has always been referred to as a monotypic genus included in the tribe Rondeletieae. Morphological comparisons have revealed thatB. brasiliensis is synonymous withSimira glaziovii (K. Schum.) Steyerm. In addition, what Wernham called the “Schau-Apparat” made of “modified bracts, the calyx-lobes being approximately equal” (an erroneous observation repeated by recent authors), is here shown to consist of calycophylls inserted on aborted flowers. A complete description and illustrations of this species are provided.
