Two new species of potamonautid freshwater crabs are described from the Imatong Mountains and Mount Moroto in northern Uganda, East Africa, and a third highland species, Potamonautes amalerensis (Rathbun, 1935) stat. rev. from Mount Kadam is re-diagnosed based on examination of the holotype. All three species are endemic to a different mountain range and their collection localities indicate a distinct preference for higher altitudes. Diagnoses, illustrations and distribution maps are provided for these taxa, and they are compared to similar species from the region. The conservation status of all three species is discussed.

Three new species of potamonautid freshwater crabs are described from the Lake Victoria region in southern Uganda, East Africa. Two of the new species (Potamonautes busungwe sp. nov. and P. entebbe sp. nov.) are from the shores of Lake Victoria, while the third (P. kantsyore sp. nov.) is from an inland locality on the Kagera River that flows into the lake. In addition, two of the new taxa (P. busungwe sp. nov. and P. kantsyore sp. nov.) are among the smallest species of freshwater crabs so far known from Africa. Diagnoses, illustrations and distribution maps are provided for these taxa, which are compared to similar species from Uganda and elsewhere in East Africa.

Two new species of Graffenrieda are described from the Amazon rainforest. Graffenrieda maturaca is characterized mainly by its leaves which are dull on the adaxial surface, chartaceous, narrowly elliptic to oblanceolate, and apparently uni-nerved, with only the median acrodromous vein evident. This species has been collected only at Serra de Maturacá, in the state of Amazonas, Brazil. Graffenrieda goldenbergii is distinguished mainly by the pulverulent, whitish, early caducous indumentum of the rachis, pedicel, hypanthium and calyx, by the abaxial surface of the leaves which is moderately lepidote, with trichomes ca. 0.2 mm diam., by the irregularly valvate calyx, and by the membranaceous, costate, not sulcate fruits. This species has been collected in the state of Acre, Brazil, and in the Province and District of Lama in Peru. Both species are illustrated, compared with similar species, and their conservation status is discussed.

Two apparently narrow-endemic species of Eugenia are described from the Cabo Frio Center of Plant Diversity in the state of Rio de Janeiro, Brazil. Both present a limited distribution restricted to coastal areas north of Rio de Janeiro. The new species are described and compared with closely related species.  Illustrations, distribution maps and conservation status assessments are also provided. Eugenia gastropogena and Eugenia farneyi are presumably closely related to Eugenia pyriformis and Eugenia malacantha. Eugenia gastropogena can be recognized by its leaves with arched secondary veins not forming a clear marginal vein, subcordate to obtuse leaf bases, petioles 2.1–4.8 mm long, buds 3.5–4 mm long and 2 ovules per locule. E. farneyi can be recognized by having leaves with straight secondary veins that form a single marginal vein running 0.7–1.5 mm from the margin, cuneate leaf bases, petioles 4–6.4 mm long, buds 6.2–8.4 mm long, and 10–12 ovules per locule.

Adenocalymma, with approximately 75 species, is one of the largest genera from tribe Bignonieae (Bignoniaceae). The genus mostly includes yellow-flowered lianas and shrubs that are conspicuous components of the dry and wet Neotropical forests. As part of an ongoing taxonomic and phylogenetic study of this group, we found unusual materials that do not match any of the currently recognized taxa. These materials formed the basis of two new species described here, which are endemic from the Brazilian Atlantic forest: Adenocalymma lineare, and Adenocalymma apetiolatum. Adenocalymma lineare resembles Adenocalymma nervosum on the linear leaflets, but differs in the habit, prophyll morphology, leaflet venation, floral bracts, bracteole morphology and dimensions, corolla color and morphology, anther and stigma position. While Adenocalymma apetiolatum closely resembles Adenocalymma sessile and Adenocalymma subsessilifolium on the sessile leaf insertion and shrubby habit, it differs from both species by the corolla color, indument type and color. Apart from that, Adenocalymma apetiolatum differs from the former by the prophyll morphology, floral bract and bracteole morphology, and the latter by the corolla morphology. These two new taxa are illustrated, and distribution maps are provided here. Notes on the taxonomy, geographic distribution, habitat, and conservation status are also included.

Homollea Arènes (Rubiaceae, subfamily Ixoroideae, tribe Pavetteae) is a genus of shrubs and small trees endemic to western and northern Madagascar. The genus comprises five species occurring in dry deciduous forest, often in limestone areas. The five species are narrow endemics and their conservation status is either Endangered (4 species) or Critically Endangered (1 species). Homollea is characterized by few-flowered, pseudo-axillary, pedunculate inflorescences, well-developed calyces with the lobes much longer than the tube, laterally flattened seeds with a shallow, elongated to linear hilum and entire endosperm, ovules arising from the upper margin of the placenta, and, pollen grains with supratectal elements in the shape of microgemmae. Until now, three species were known and their descriptions are amended. Two further species, H. furtiva De Block sp. nov. and H. septentrionalis De Block sp. nov., are described as new for science. The five species are dealt with in detail: descriptions, distribution maps, conservation assessments, illustrations, lists of exsiccatae and an identification key are given.

A new species of Utricularia Section Orchidioides: Utricularia amotape-huancabambensis sp. nov. (Lentibulariaceae), endemic to Northern Peru is described and illustrated. It is known from two populations so far, both located in the Province Bongará, Dpto. Amazonas at ca. 2200 m altitude. The new species inhabits the páramo of the low white sandstone plateaus, an extension of the southern branches of the Condor mountain range in the southeastern part of the Amotape-Huancabamba phytogeographic zone. A diagnosis, description, etymology and an identification key covering the Andean and selected similar species of the section are presented. The distribution, habitat, ecology, associated flora, preliminary conservation status, an observed hybridization with sympatric U. unifolia and the affinities of the new species with other related taxa are discussed. The new species is known from two close-by populations in the same region and likely affected by anthropic pressure. Threatening changes in land use, resulting in habitat fragmentation or loss or changing water regimes in the course of climate change will have severe consequences for the sensitive páramo ecosystem and thus the populations of U. amotape-huancabambensis. Therefore, this new spectacular species of Utricularia is preliminarily considered Critically Endangered (CR).

Isoetes dubsiisp. nov. and I. santacruzensissp. nov., two new species from lowland areas in South America, are described, illustrated and compared to similar species. Isoetes dubsii can be distinguished from other species of the Brazilian Pantanal wetlands by a set of characters including leaves that are long, flexuous and trigonal in transverse section, tri-lobate stems, rudimentary velum, pustulate megaspores of 310‒390 µm diameter and laesurae of the megaspore at least four times wider than high. Isoetes santacruzensis has flexuous, filiform leaves, 0.4–0.8 mm wide at mid length and reaching up to 15 cm long, black or reddish-black sporangia, sclerified phyllopodia and sparsely verrucate megaspores of 320‒390 µm in diameter. We also include a key for species from the Brazilian Pantanal wetlands and Bolivia and spore images for all species that are discussed. Isoetes dubsii and I. santacruzensis are only known from their type localities and they may deserve special attention concerning their conservation status. However, based on our current knowledge on these species and according to IUCN Red List criteria, they are assessed here as data deficient (DD).
