Sciodaphyllum P. Browne (Araliaceae) has recently been resurrected to accommodate the majority of Neotropical species previously included in Schefflera J. R. Forst. & G. Forst. Recent field and herbarium studies have revealed many distinctive new species of Sciodaphyllum, including three from the eastern slopes of the Andes in central Peru, which are described and illustrated here: S. geniculatum M. M. Mora, Lowry & G. M. Plunkett, S. oxapampense G. M. Plunkett, Lowry & M. M. Mora, and S. rodolfoi Lowry, G. M. Plunkett & M. M. Mora. The conservation status of S. geniculatum is assessed as Vulnerable (VU) using the IUCN Red List categories and criteria, whereas both S. oxapampense and S. rodolfoi are assessed as Near Threatened (NT).

Three new species of Lepanthes from Ecuador are described and illustrated. These additions to the Ecuadorean flora were recorded in evergreen montane forest and páramo as part of three different research projects conducted during the last five years (2016–2021). Lepanthes oro-lojaensis was discovered in the southwest of El Oro province and is similar to L. jimburae, differing mainly in the much smaller plants, inflorescences and floral parts. Lepanthes microprosartima from the western slopes of Pichincha volcano in northern Ecuador resembles L. obandoi but differs in the coloration of the leaves, the inflorescence that are shorter than the leaves and the smaller floral appendix. Lepanthes caranqui, found in eastern Pichincha and Imbabura, is most similar to L. pachychila but differs from it in its much larger plants and different shape of the petals and the floral appendix. Preliminary assessments of the conservation status of the three taxonomic novelties are provided, using the IUCN Red List Categories and Criteria.

Spiradicliskarstana, a new species of Spiradiclis (Rubiaceae) collected from Yunnan, China, is described for the first time. It is morphologically close to S.jingxiensis, but differs from the latter mainly by its inflorescences with 5–9 flowers, its 1.5–2.4 mm long peduncles, its stipules shorter than 1 mm and the 5–12 pairs of secondary veins. The conservation status is assessed as “Vulnerable” (VU) according to the IUCN Red List Categories and Criteria.

Abstract—Valeriana caparaoensis, a new species from the High Altitude Tropical Grasslands of Southeastern Brazil, is described and illustrated. The new species is known only from the Serra do Caparaó massif, between the states of Minas Gerais and Espírito Santo, Southeastern Brazil. It shares morphological affinities with V. catharinensis and V. polystachya, the first restricted to Brazilian Subtropical Highland Grasslands, and the last restricted to Lowland Grasslands of Southern Brazil, Uruguay and Argentina. Besides the great geographical disjunction, the new species differs from the other two species by the pinnately lobed proximal leaves, by the lanceolate distal lobes and longer pseudopetioles in distal leaves, by differences in the size of the flowers, and by the rounded to ovate and broader achenes. Additionally, we provide the preliminary conservation status assessments using IUCN Red List categories and criteria, as well as an updated checklist and a key for Valeriana species from Southeastern Brazil.

Allium shahinii, a new species of Allium sect. Scorodon, is described and illustrated from Erzincan Province, Eastern Turkey. It is a narrowly distributed geophyte growing on siliceous screes of warm exposure in mountain ranges of the nemoral and thermophilous deciduous woodland zone, showing close morphological relationships mainly with A. moschatum, A. stocksianum, A. spirophyllum, A. circumflexum but it is clearly differentiated due to perigon, outer tunic, indumentum, leaf and scape characteristics. In this study, diagnostic characters, description, taxonomic comments, photographs, distribution map, detailed illustration, the conservation status of A. shahinii and identification key are provided for A. shahinii and related taxa. According to IUCN Red List Categories and Criteria, A. shahinii is assessed here as a Critically Endangered (CR) species.

Here we describe Paraboea dolomitica Z.Y. Li, X.G. Xiang & Z.Y. Guo, a new species of Gesneriaceae from Guizhou, China. Based on recent extensive observations, this new species is morphologically similar to Paraboea filipes (Hance) Burtt, in having obovate leaf blades, 1–4-flowered cymes and purplish corolla, but differs from that species by the combination of denticulate leathery leaves, sparsely brown haired peduncles, two woolly bracts, reniform anthers and two glabrous staminodes. Additionally, molecular data support this new species as a member of a clade that includes P. crassifolia, P. tetrabracteata, P. peltifolia, P. vetutina, P. dushanensis, P. dictyoneura, P xiangguiensis and P. guilinensis, but it is distinct from them in leaf position, inflorescence, penduncle, bract and capsule. The conservation status of this species is considered to be “Vulnerable” (VU) according to the IUCN Red List Categories and Criteria.

We describe and illustrate three new species of Freziera collected from the “ceja de monte yungueña” cloud forests in Bolivia and Peru. Freziera apolobambensis and F. erickitae, both endemic to Bolivia, have small leaves and pink-magenta flowers, whereas F. magnibracteolata, found in Peru and Bolivia, is characterized by its adaxially pubescent leaves with whitish beige trichomes and inflorescences with large bracts and bracteoles. An extinction risk assessment based on the IUCN Red List categories and criteria indicates that F. apolobambensis should be considered Critically Endangered (CR), whereas F. erickitae and F. magnibracteolata should be considered Endangered (EN). The distribution, phenology, and habitat of the new taxa are provided, and affinities with their presumed closest relatives are discussed.

Hemiboea chanii, a new species of Gesneriaceae from Ha Giang Province, northern Vietnam, is here described and illustrated. It has many branched stems, diamond-shaped involucre with two cirrose opposite apices, a pink corolla, red spotted inside, and a flowering time in January-February. Among congeners with an externally hairy corolla, this new species is morphologically close to H. crystallina and H. sinovietnamica. Diagnostic discriminative characters in all mentioned species are discussed. The conservation status of this species is considered to be “Critically endangered” (CR) according to the IUCN Red List Categories and Criteria.

Abstract—The new species Alectryon hirsutus is described from New Caledonia. It is distinguished from the only other member of the genus occurring on this southwest Pacific island, A. carinatus, by its uniformly densely hirsute indumentum (vs. glabrous or with short, appressed trichomes) as well as features of its leaves [(2‐)3‐5 pairs of leaflets vs. 1‐2]) and fruits (9‐16 × 16‐28 mm vs. 5.6‐13 × 5.7‐10.6 mm), along with its presence in dense humid forest (vs. sclerophyllous or lowland dry forest). A preliminary conservation status of Critically Endangered [CR] is suggested following IUCN Red List Categories and Criteria.

Five new species of Peperomia (Piperaceae), endemic to the state of Veracruz, Mexico, are described, illustrated, compared with morphologically close taxa and assigned to their respective subgenus. Peperomia castilloi Vergara-Rodríguez & Jimeno-Sevilla, P. nopalana G.Mathieu, P. trichobracteata G.Mathieu & T.Krömer and P. xalana G.Mathieu are four somewhat similar species that occur at lower elevations in tropical humid forests. Peperomia zongolicana Jimeno-Sevilla & Vergara-Rodríguez occurs in tropical humid forests at mid-range elevations and is very distinct by the shape of its inflorescences. An assessment of their conservation status, considering IUCN Red List categories and criteria, revealed that they all belong to a threatened category, mainly due to the continuous loss and fragmentation of their natural habitats.

Strobilanthes hongii, a new species of Acanthaceae is described and illustrated from Libo, Guizhou, China. The new species is similar to S. pateriformis and S. truncata, but differs by the characters of leaf blade, bracteole and calyx and pollen grains. The new species is plietesial and grows in forest on limestone hills. The conservation status of S. hongii is assessed as “Vulnerable (VU)” according to the IUCN red list categories and criteria.
