New Synonym

Open grasslands are the usual habitats of Eriocaulaceae, but a few species also grow in forest understory. Paepalanthus macaheensis grows exclusively in shaded habitat, and has broad morphological variation and a confusing taxonomy. Here, the nomenclatural history associated with this species is clarified, the name is formally reestablished, and a second-step lectotype for the name is designated. Paepalanthus euryphyllus is proposed as a new synonym of P. macaheensis and comparisons with morphologically similar species are presented. A detailed description, the first line drawings of P. macaheensis, photographs, and a distribution map are provided. An official conservation status of endangered was assessed by the Brazilian National Center for Flora Conservation (CNCFlora).

We describe and illustrate Paepalanthus capixaba, a new species of Paepalanthus ser. Paepalanthus. The species is endemic to Espírito Santo state and restricted to a very distinct and endangered area, which comprises a mosaic of quartzitic sandy patches within a granitic argillaceous site. The indument of leaves, spathes, and scapes is crucial to recognize the taxon as a unique entity. The species is compared to Paepalanthus klotzschianus, the morphologically most similar species. An official conservation status of critically endangered species was assessed by the Centro Nacional de Conservação da Flora committee. Comments on the occurrence area and the morphological variation of the species, as well as a distribution map, photos, and illustrations are provided.

Lippia horridula is an endemic species from the Brazilian Cerrado with exclusively post-fire flowering records. It is often confused in herbaria collections with Lantana glaziovii and Lippia grandiflora, due to the subshrubby habit, the flowering branches raising from a well-developed xylopodium, and the pink colored corollas. Lippia horridula presents different morphotypes during its vegetative and flowering stages related to the fire regime in the Cerrado. The absence of observation and description of such variations has led to taxonomical confusion regarding its identity. Thus, in order to clarify this, we here present the morphological variation of this species during the vegetative and flowering stages, including modifications in the habit and remarkable heterophylly related to fire regime. An epitype is here designated to aid in the proper delimitation of this species. Moreover, a new record in the state of Maranhão (the northernmost known record for this species) is here presented, plus information about its conservation status, a geographical distribution map, in addition to a comparison with morphologically most similar species.

Reknowned for its high biodiversity and endemism, over one third of the Bornean species of Phyllagathis were discovered in Sarawak over the past two years. In this study, we report an addition of a new species of Phyllagathis, namely P. stellata from southwestern Sarawak. In addition to the taxonomic account, color plates, line drawings, a distribution map, and comparisons with morphologically similar species are provided to aid in identification.

Phylogenetic studies indicate that several infrageneric taxa in Oxalis require taxonomic updates to attain monophyly. In this contribution, we update the morphological delimitation of the South American Oxalis sect. Ripariae and provide a taxonomic revision of the currently accepted species. The sectional delimitation was carried out by comparing micro- and macromorphological features of Oxalis sect. Ripariae, O. sect. Corniculatae, and O. sect. Myriophyllum. These sections share yellow flowers and aerial stems. Glandular hairs and larger seeds with the surface longitudinally crested and with projections are exclusive to Oxalis sect. Ripariae. We accept 11 species in the section, including three previously placed in Oxalis sect. Corniculatae (i.e., O. eriocarpa, O. niederleinii, and O. refracta), but excluding O. serpens and O. subvillosa, which are moved to O. sect. Corniculatae. We also describe a new species (Oxalis lourteiginana), propose a new name and status for O. bifrons subsp. littoralis (now O. pampeana), the synonymization of O. irreperta with O. riparia, six second-step lectotypifications, and one epitypification. For each accepted species we provide a morphological description, illustrations, ecological and taxonomic information, conservation status following IUCN, and a geographic distribution map. Most species occur in southern Brazil, but the section is widespread also in Argentina, Uruguay, and eastern Paraguay. Six species are categorized as threatened and further three as near threatened. Besides, we provide an identification key for the taxa of the section.

We describe and illustrate Wahlenbergia itatiaiensis, a new species of Campanulaceae, endemic to the Itatiaia National Park in the Atlantic Forest (Brazil). The new species is compared with W. linarioides, the sympatric and morphologically most similar species, and to W. intermedia. Wahlenbergia itatiaiensis is mainly distinguished by the linear to lanceolate leaves with few, short denticles along the margin, 3-locular ovary, and 3-lobed stigma. An identification key for these species is provided. The new species occurs on sandy and rocky, wet soils, adjacent to dirt roadsides of the upper part of the National Park. Detailed comments on the distribution and conservation status, as well as details of morphological variation and photographs are provided.

Schinus pampeana is a new species from Brazilian Pampa. The new species was tentatively included in Schinus sect. Terebinthifolia, and is morphologically most similar to Schinus lentiscifolia and S. weinmanniifolia. We present here a detailed morphological description, a geographical distribution map, IUCN conservation status assessment, ecological data, photographs, and a table of diagnostic characters of S. pampeana and the most similar species. Schinus pampeana increases the total number of Schinus to about 49 species, of which eleven are recorded in Brazil.

Microlicia woodii is described as a new species from the Meseta de Motacú, Santiago de Chiquitos, eastern Bolivia, a region rich in endemic plants. The new species seems to be closely related to Microlicia sphagnicola, and can be recognized by a combination of elliptic leaf blades 8–10 × 3.2–5 mm, glandular-punctate on both surfaces, petioles 0.2–0.4 mm long, rectangular and dorso-ventrally flattened, solitary 5–6-merous flowers, external and internal intercalycine eglandular trichomes ca. 1–2 mm long, pink petals, and dimorphic, bicolored and polysporangiate anthers. Line drawings, photographs, a distribution map, and notes on its conservation status are provided. Additionally, we designate a lectotype for Microlicia insignis and document the first records for this species in Bolivia, at Parque Nacional Noel Kempff Mercado.
