03932368FFD11105FF28F8410282FE95.taxon	distribution	Distribution, habitat, phenology: — This species is presently known from the municipalities of Anori and Codajás, in the central portion of the northern Brazilian state of Amazonas, where it grows in floodable forests (“ várzea ”); flowers were collected in July and August and fruits in August, along periods where the forest was flooded and only canopies of trees were above water level.	en	Sobral, Marcos, Souza, Maria Anália Duarte De, Luize, Bruno G.

03932368FFD11105FF28F8410282FE95.taxon	discussion	Affinities: — The flowers of Calyptranthes irregularis either open through a well-defined calyptra or an irregular splitting of the lobes, a morphology intermediate between the genera Calyptranthes Swartz (1788: 79), defined by the anthesis through one circular piece, and Marlierea Cambessèdes (1832 – 1833: 373), characterized by a calyx that tears in irregular lobes. These two genera are recognized as closely related and were merged by Lucas et al. (2011), together with Gomidesia O. Berg (1855 – 1856: 27) and Myrcia De Candolle (1827: 406) in the assemblage dubbed the “ Myrcia group ”. Lucas et al. (2011) note that recognizing only one generic name for this clade would be phylogenetically more sound; nevertheless, Calyptranthes is the older name and until Myrcia might be conserved against it (for details of proposal to conserve, see Lucas & Sobral 2011), the name to be taken for this group is still debatable. Since this proposal must wait for a future official decision of the International Association for Plant Taxonomy, both names are still currently used and we then assign this species to Calyptranthes. Calyptranthes irregularis is apparently related to the Amazonian Calyptranthes cuspidata Martius ex De Candolle (1828: 258; see also Berg 1857 – 1859: 39; image: K barcode 000331104!), from which it is distinguished by the characters given in the diagnosis.	en	Sobral, Marcos, Souza, Maria Anália Duarte De, Luize, Bruno G.

03932368FFD11105FF28F8410282FE95.taxon	conservation	Conservation: — This species was collected in two contiguous scarcely surveyed municipalities of the state of Amazonas, Anori and Codajás, with respectively 5,700 km ² and 18,700 km ² (IBGE 2015 b) and 360 and 282 collections (CRIA 2015). Since the collections of this species bear geographical coordinates, it was possible to estimate its extent of occurrence via Geocat (Bachman et al. 2011), which is of 800 km ², an area smaller than 20,000 km ² (criterion B 1 for Vulnerable, see IUCN 2001); considering that the species is known from three locations, it fulfills criterion B 2 a for Vulnerable; although a thorough evaluation would need information about the quality of environment, we do not have these data (see criteria B 2 b in IUCN 2001). So, even with an incomplete set of data, we suggest this species to be scored as Vulnerable (VU) according to IUCN criteria.	en	Sobral, Marcos, Souza, Maria Anália Duarte De, Luize, Bruno G.
