A new species of Eriotheca (Malvaceae, Bombacoideae) from coastal areas in the northeastern Brazilian states of Alagoas and Bahia is described and illustrated. Eriotheca alversonii inhabits Atlantic coastal forest and is found principally on sandy soils in restinga vegetation. It is most similar morphologically to E. parvifolia. Both species have 3-foliolate leaves and short petioles on fertile branches, but the new species has smaller flowers, truncate to crenulate calyces, and smaller globose to subglobose capsules. The affinities of E. alversonii to morphologically similar species and its phenology are discussed. A distribution map and preliminary assessment of its conservation status are provided.

Begonia fimbritepala (Begoniaceae) a new endemic species to the Atlantic Coastal Forest of Brazil is described and illustrated. This species resembles B. olsoniae in occupying the same habitat (rocky slopes and outcrops), and in the shape of the leaf blades and size of male flowers. It differs by glabrous leaves on the adaxial surface, villous abaxial veins with simple trichomes (vs. hispid on both surfaces, squamulose on abaxial veins with fimbriate scales) and tepals with ciliate margins (vs entire to slightly crenulate).

Begonia itaipeensis (Begoniaceae), a new narrow endemic species from the Brazilian Atlantic Coastal Forest is described and illustrated. This species resembles B. friburgensis Brade but is readily distinguished from that species by its rupicolous habit, leaves with long petioles, and transversely ovate leaf blades.

Begonia microinduta, a new species of  Begonia sect. Pritzelia from the Atlantic Coastal Forest of Brazil is described and illustrated with detailed field photographs. This species is similar to B. windischii and B. lorenzii by having three tepals on pistillate flowers, staminate flowers with pilose dorsal surface, short peduncled inflorescences, very short inflorescence ramification and persistent floral bracts. It differs from B. windischii in its petiole indumentum, which is covered with short microscopic trichomes throughout (vs. sparsely pilose in the upper third with villous trichomes, with a trichome necklace at the base of the petiole and in the apex) and differs from B. lorenzii by having microscopic (vs. villous) trichomes, glabrous (vs. pubescent) adaxial leaf surface and glabrous (vs. pubescent) fruits.

Abstract—A new species of Dyckia (Bromeliaceae, Pitcairnioideae) from Maranhão, Northeastern Brazil is described and illustrated. Dyckia maranhensis is endemic in the cerrado phytogeographic domain and it was erroneously identified as D. braunii Rauh in herbarium collections. Information on its phenology, distribution, and conservation status is provided. The species is morphologically compared to D. dissitiflora Schult. & Schult. f., which is the most similar species.

Begonia erythrobracteata (Begoniaceae) is a new, narrow endemic from the Atlantic Coastal Forest of Brazil. This species is closely related to Begonia olsoniae and B. fimbritepala and shares their rupicolous habit and transversely ovate leaf blades with a cordate base. It differs to B. fimbritepala in its petioles, which are densely squamulose along their entire length (vs. with simple trichomes) and B. olsoniae by its glabrous (vs. pilose) adaxial leaf surface. B. erythrobracteata is described and illustrated with detailed field photographs, and a provisional IUCN Red List Assessment is provided.

Two species of Eugenia from the Brazilian Atlantic coastal forest of Bahia and Espírito Santo are here described. Eugenia atlantica is most similar to E. bahiensis from which differs by its leaf blades usually larger, 80–180 × 35–70 mm, and chartaceous, inflorescence mostly axillary, flower buds with hypanthium costate to slightly costate and calyx lobes completely fused or partially fused along two thirds of the bud length. Eugenia soteriana is related with E. zuccarinii but differs mostly by the leaves with two marginal veins, inflorescence fasciculate more often recovering the vegetative growth by an auxotelic axis, bracteoles larger, 2–6 mm long, deciduous after anthesis, and flowers with larger outermost calyx lobes, 1.5–3 mm long. Descriptions, species distribution, habitat, phenology, vernacular names, illustrations, comparisons to other morphologically similar species, and conservation assessments are also provided.

Lepidaploa restingae, a new species from the restinga vegetation in Northeastern Brazil, is described and illustrated. This new species differs from morphologically related species by the branch indument, leaf morphology, number of phyllary series and corolla lobe indument. Taxonomic comments, a distribution map and a preliminary conservation status for the new species are provided.

Background and Aims: Aristolochia is the largest genus in Aristolochiaceae and is widely distributed in the world. A recent synopsis of Aristolochia in Costa Rica recognized 19 species; nevertheless, recent botanical exploration in southwestern Costa Rica has revealed yet another new species of this genus. Methods: The new species resulted from fieldwork in Buenos Aires, Puntarenas Province. Specimens from several herbaria were examined, as well as the type material of the most morphologically similar species. Comments about its distribution, habitat, phenology, conservation status and morphological distinction from related species are provided.Key results: Aristolochia quiricoana, a member of Aristolochia series Thyrsicae, is described and illustrated from the southern Pacific region of Costa Rica, where it is apparently endemic. It is similar to A. ornithorhyncha, from which it is distinguished by its shorter pedicels, wider, oblong perigone limbs with a shorter appendix, and a different floral color pattern.Conclusions: The new taxon described here represents the 22nd species documented in Aristolochia series Thyrsicae, as well as the 20th species of the genus from Costa Rica.
