Impatiens uncata, a new species from Ningyuan County, Hunan, is described and illustrated. The new species is superficially similar to I. huangyanensis in having racemose and 2-flowered (rarely many-flowered) inflorescences, fusiform capsule and ellipsoid seed, but is distinguishable from the latter by its obviously taller height, leaves with ovate or ovate-lanceolate blades and longer petioles, purple flowers, longer bracts, broadly ovate-rounded lateral sepals, white broadly funnelform lower sepal, 2-lobed spur with a swollen apex, purplish dorsal petal, white basal lobes, and bigger distal lobes with a retuse apex.

The species diversity of certain groups of ferns in Indo-Burma Biodiversity Hotspot remains largely unexplored using combined molecular and morphological approaches. Here, based on morphology and an updated phylogeny of Leptochilus with 121 (115% increase of the latest sampling) new samples across Asia added, specifically those of three systematically significant “old” species, L. ovatus, L. pedunculatus, and L. pothifolius, we discovered 11 new species of the genus and made two new combinations. The new species are described in detail, the taxonomic treatment is given, and a key to the 51 currently known species of the genus is provided.

The genus name Kalanchoe, which is in use for about 200 tetramerous-flowered infrageneric taxa, species, and infraspecific taxa of Crassulaceae subfam. Kalanchooideae that are indigenous to Madagascar, some Indian Ocean islands off the African east coast, most of sub-Saharan Africa, and the Near, Middle, and Far East, was validly published in 1763 by Michel Adanson (1727–1806) and is legitimate. Genus names that are included in the synonymy of Kalanchoe are assessed and assigned to the appropriate subgenera recognised in the genus, and their nomenclature is reviewed. In chronological sequence the genus names in question are: (1) Vereia (1798), (2) Physocalycium (1820), (3) Baumgartenia (1821), (4) Meristostylus (1861), and (5) Geaya (1908); and (6) Bryophyllum (1805) is the basionym of K. subg. Bryophyllum (1919), and (7) Kitchingia (1881) is the basionym of K. subg. Kitchingia (2018). When Bryophyllum is treated as a synonym of Kalanchoe—a view followed here—the nothogenus name (8) ×Bryokalanchoe (1956) is a synonym of Kalanchoe.

Dimerostemma pantanalense is a new species, which is described, illustrated, and discussed in this paper. The species can only be found in the municipalities of Ladário and Corumbá, Mato Grosso do Sul state, Pantanal, Brazil. It is preliminarily categorized as Critically Endangered (CR) due to the advance of urbanization and the risk of fires in the Pantanal. It is morphologically similar to D. annuum but differs by its life-cycle perennial (vs. annual), leaves opposite and alternate (vs. only opposite), sessile (vs. subsessile with petiole up to 5 mm long), lanceolate (vs. linear), venation suprabasal acrodromous imperfect (vs. hyphodromous), adaxial and abaxial leaf surfaces strongly villous to estrigose and glandular (vs. only nearly glabrous), receptacle convex to conical (vs. only convex), phyllaries 3-seriate (vs. 2-seriate), conduplicate palea carinate-alate (vs. not carinate-alate), cypselae oblanceolate to obovate (vs. subquadrangular) and pappus coroniform with two slightly developed awns (vs. coroniform with two well-developed awns). We present photographs and line drawings of the new species, along with discussions on its geographical distribution, habitat, phenology, and conservation status. Additionally, we provide an identification key for species of the genus in the Brazilian Pantanal.

A new species of Kalanchoe (K. [subg. Kalanchoe sect. Raveta] ser. Rotundifoliae; Crassulaceae subfam. Kalanchooideae), K. steyniae, is described from the northeastern parts of South Africa’s KwaZulu-Natal province and neighbouring Eswatini in eastern southern Africa. Kalanchoe steyniae differs from K. rotundifolia in especially reproductive characters, with, inter alia, its flowers being densely arranged (not diffusely so) in ± flat-topped, corymbose cymes; its corolla lobes showing weak (not distinct) diurnal movement; its sepals being longer; and its corolla tubes and corolla lobes being bright crimson red (not dull red to orange). Both species are illustrated.

Our continuous investigation into the diversity of psathyrelloid mushrooms in Kerala State, India, has led us to discover two new species of Candolleomyces viz., C. niveosquamosus and C. rubrobrunneus. Comprehensive morphological evaluations and multigene phylogenetic analyses involving nrITS and nrLSU served as the basis for describing these two new species. Comprehensive descriptions, photographs, and a discussion with related species are provided.

John Forbes (1799–1823) briefly visited South Africa’s present-day Eastern Cape province on three occasions, once in the spring of 1822 and twice in 1823, in autumn and in mid-winter, respectively. An analysis is presented of his collecting activities after he disembarked in what is now Nelson Mandela Bay. During these three visits, Forbes spent a total of ten days in the vicinity of Port Elizabeth (now Gqeberha) and Uitenhage (now Kariega). During this time he made 119 plant collections. Forty-nine of these have been located, two further collections cited in the literature have not been located; the collections are mostly unnumbered and labelled with scant information. The whereabouts of the majority of the collections remain unknown and the information available is that given by Forbes in his fieldbooks. His collections from the Eastern Cape include 12 type specimens. By comparing the Forbes specimens with his fieldnotes, the collecting number, date, and locality are confirmed or posited here for 23 collections. The present-day occurrence in Gqeberha of the taxa Forbes collected in 1822 and 1823 is given.

The taxonomy regarding three closely related genera of Agaricaceae, viz. Heinemannomyces, Hymenagaricus and Xanthagaricus, is updated based on morphological and four-locus molecular phylogenetic evidence from collections gathered in South China. Thirteen species identified from 122 collections are described, including Heinemannomyces splendidissimus, eight new species of Xanthagaricus, viz. X. boluoshanensis, X. chamaeleontinus, X. guangzhouensis, X. heinemannii, X. minimus, X. phylononcaeruleus, X. retisporus and X. scauinus, and four known species of Xanthagaricus, viz. X. erinaceus, X. ianthinus, X. necopinatus and X. purpureosquamulosus. Among them, He. splendidissimus is phylogenetically recognized as a Hymenagaricus species, namely Hy. splendidissimus, and Xanthagaricus heinemannii is morphologically similar to Hy. splendidissimus in floccose squamules on the pileus and stipe. Both species have pileus squamules composed of inflated cells in the lower layer and hyphae forming an irregular trichoderm in the upper layer. However, X. heinemannii differs from Hy. splendidissimus by the context not turning reddish after damaged, brownish lamellae, and usually without hymeniform elements in pileus squamules. These findings suggest that species of both Hymenagaricus and Xanthagaricus may present hyphae forming an irregular trichoderm in pileus squamules. Xanthagaricus erinaceus is rediscovered after 40 years, together with X. necopinatus and X. purpureosquamulosus are three newly recorded species in China.

We describe Miconia leonorae, a new species exclusive to eastern Brazil, mainly from the evergreen forests of the Atlantic Forest Domain. This species can be distinguished from a wider circumscription of Miconia lepidota. It is classified as Miconia supersect. Discolores sect. Multispicatae and can be distinguished from similar species by features such as an acute leaf base and apex, light brown to gray abaxial leaf blade indumentum with lepidote-stellate trichomes (becoming glabrescent on mature leaves), cylindrical, scorpioid inflorescences with basal branches only bifid or trifid, and an androecium with isomorphic stamens.
