Amended description and conservation status of Stigmaphyllon carautae (Malpighiaceae)

The orchid-bee faunas (Hymenoptera: Apidae: Euglossina) of the three largest forest remnants in the “Centro de Endemismo Pernambuco”, northeastern Brazil, namely Estação Ecológica de Murici (ESEC Murici), RPPN Frei Caneca, and a forest preserve belonging to Usina Serra Grande, in the states of Alagoas and Pernambuco, were surveyed using seventeen different scents as baits to attract orchid-bee males. Eight sites were established in the three preserves, where samplings were carried out using two protocols: insect netting and bait trapping. We collected 3,479 orchid-bee males belonging to 29 species during 160 hours in early October, 2012. Seven species were collected in the “Centro de Endemismo Pernambuco” for the first time. Richness proved to be one of the highest of the entire Atlantic Forest domain, and diversity in some sites, especially at ESEC Murici, revealed to be one of the highest in the Neotropics. Eulaema felipei Nemésio, 2010, a species previously recorded only at ESEC Murici, was found in no other preserve in the region and its conservation status is discussed.

A New Species

Flueggea acicularis (Phyllanthaceae) is endemic to the karst region of central China. Male specimens of this species were first collected in 1908. In 1989, female plants of F. acicularis were found for the first time, but misidentified as a new species. Throughout this period the male plants of F. acicularis were mismatched with female plants of other species, and male plants had not been collected since 1908. Then, in March, 2009, the authors rediscovered a wild population of F. acicularis consisting of both male and female plants in Wuxi county, Chongqing municipality, China. Based on field investigation and examination of specimens, we matched the correct female and male plants of this species for the first time since its initial publication a century ago. A complete and accurate morphological description, distribution, habitat and phenology of this species are also provided. Furthermore, the conservation status of F. acicularis is assessed as “Near Threatened” (NT) according to the IUCN Red List criteria.

Botanical explorations were carried out in eastern Colombia sub-xerophytic enclaves, as well as examination of specimens deposited at the herbaria AZUAY, COL, GH, NY, QCA, QCNE, UPTC, and US was made. Lectotypes for the names O. dobbieana (here treated as heterotypic synonym of O. soederstromiana) and O. soederstromiana are designated on specimens preserved at US and NY. A detailed and expanded morphological description of O. soederstromiana, as well as data about type, habitat, conservation status, selected iconographies, and distribution area were given. The number of Opuntia species recorded in Colombia has increased to 10. A key for identification of Opuntia species occurring in the departments of Boyacá and Santander (Colombia) was also provided.

The Atlantic Forest is a biodiversity hotspot that includes different types of phytophysiognomies, mainly forests. Hornschuchia, Annonaceae, is one of its endemic genera. Eight Hornschuchia species are found in the tropical moist forest, three of them both occurring in tropical moist forest and tabuleiro forest, a semideciduous seasonal forest, one occurs in the coastal semideciduous seasonal forest and two inhabit the semideciduous seasonal forest and deciduous seasonal forest far from the coast in Bahia. Here we describe the twelfth species of Hornschuchia, which occurs in the Bahian semideciduous seasonal forest, and present a morphological description, illustration, distribution map and assessment of its conservation status.

A New Species

A new species, Myrcia suberosa, is here proposed based in an ongoing taxonomic revision of Myrcia sect. Eugeniopsis, a group nearly endemic to the Atlantic Forest. Myrcia suberosa occurs in Brazil from Southern Bahia to Southern Rio de Janeiro states, but only three collections are known and the real distribution of the species is barely known. The new species is morphologically related to Myrcia pseudomarlierea and Myrcia teuscheriana, differing by sexual system, cork thickness, indument, and leaf and flower morphologies. Morphological description, images and conservation status are provided, as well as discussion about distribution, habitat, phenology and taxonomy.

We present a synopsis of a rare and little-known species of Distimake from Western India: a complete morphological description based on recent collections is provided, and nomenclature and typification issues are resolved. The fruit and seeds are described for the first time. With new morphological evidence and a full characterization of D. rhyncorhiza, the present study corroborates its placement in Distimake and supports its identity as a distinct species. The conservation status is assessed as Endangered but its distribution range is not yet fully documented and this assessment might be reviewed if more collections are made.

An updated description of Galianthe vaginata is here presented. This species is endemic to the Serra da Mantiqueira and Serra do Mar, Southeast Brazil, and occurs in remnants of the Atlantic forest phytogeographic domain, in the campos de altitude, rocky outcrops, and along trails in montane rainforest. Its bracts, short-styled flowers, fruits and seeds are described and illustrated for the first time. The conspicuously winged stems and the pubescent stipules constitute a combination of diagnostic characters useful for distinguishing G. vaginata from G. polygonoides. Its conservation status is reassessed based on recent collections.

Eremitis Döll is a herbaceous bamboo genus (Poaceae, Bambusoideae, Olyreae) belonging to subtribe Parianinae that currently includes seven species. During fieldwork conducted throughout the geographic distribution of the genus, two new species with blue iridescent leaves, E. berbertii F. M. Ferreira & R. P. Oliveira and E. fluminensis F. M. Ferreira & R. P. Oliveira, from the Brazilian Atlantic forest, were collected and are here described and illustrated. Eremitis berbertii is endemic to the Private Reserve of Natural Heritage (Reserva Particular do Patrimônio Natural [RPPN]) Serra do Teimoso, in Bahia State, and E. fluminensis is restricted to the south of Rio de Janeiro State. In this study, micromorphological features of the leaf epidermis of the new species were compared with other species of the genus that display blue iridescence in their leaf blades. Variegated leaves are recorded for the first time in herbaceous bamboos. Comments on habitat, distribution, and conservation status of the new taxa are provided, as well as a revised identification key to all species of the genus described so far.

Ceropegia rudatisii Schlechter was first collected in KwaZulu-Natal, South Africa in 1903 but described in 1905 based on a second independent collection. This Ceropegia species was not seen again for a century and believed to be extinct. In 2020, however, two very small populations were discovered not far from the type locality. The subsequent examination of living flowering plants allowed an updated morphological description and, for the first time, illustration of C. rudatisii with photographs of living flowering plants and details thereof. We provide a comprehensive species description including novel aspects and details, i.e. bracts, inner corolla colouration, pollinarium and pollinia, as well as posture of corolla lobe tips of fresh flowers in situ—being not suberect-spreading, as given in earlier treatments, but flaccid-pendulous. The conservation status of C. rudatisii according to IUCN Red List criteria is furthermore discussed. Conservation measures are indispensable and urgent to avoid the extinction of C. rudatisii.

Eugenia subamplexicaulis belongs to Eugenia sect. Pilothecium and was described based on a collection made in São Paulo state by C.F.P. von Martius in 1817. After that, no other collection of this species was made until May 2018, over 200 years later, when this species was rediscovered in the rocky formation Monumento Natural da Pedra de Itaocaia, a protected area located in Rio de Janeiro state. This study provides an enhanced morphological description of the species, notes on its morphological affinities, geographic distribution and conservation status. The species can be recognized by its subsessile leaves, dichasial inflorescences and oblate fruits with up to three seeds. The fruits are described for the first time, since the original description was based only on a single flowering specimen. Additionally, the first photographic documentation of the live plant in its habitat is presented.
