Acer laurinum Hassk. was recently recorded as both a new species and genus for Singapore from the Nee Soon swamp forest in the Central Catchment Nature Reserve, but little is known about its biology and ecology. Here, the species is described and notes on its distribution, ecology and proposed conservation status in Singapore are given.

A New Species

A new species of Lagenandra (Araceae), is described and illustrated from Walauwewaththa Wathurana freshwater swamp forest, Bulathsinghala, Sri Lanka. Here we describe the new species as Lagenandra wayambae Madola, K. Yakandawala, D. Yakandawala and Karunaratne and provide a detailed description, drawing and colour photographs. We compare the morphology of L. wayambae with that of similar members of Lagenandra and conduct an assessment of its conservation status. A taxonomic key to the Sri Lankan Lagenandra is presented for easy identification. Recognizing a new endemic member enhances the number of Sri Lankan species to nine. According to the IUCN red data category guidelines L. wayambae qualifies for Critically Endangered category under Criterion B1ab (ii,iii,v) + B2ab (ii,iii,v).

Laccaria violaceotincta sp. nov. is described from Kerala State, India based on morphology and molecular phylogeny. All the collections of the species were made from a freshwater swamp forest predominantly composed of species of Myristica. The Maximum Likelihood (ML) analysis of sequence of the internal transcribed spacer (nrITS) of the ribosomal RNA gene clearly revealed its novelty as well as its position within the genus Laccaria. A taxonomic description, photographs of the basidiocarps and the micro-structures, comparisons with phenetically similar and phylogenetically related species and a phylogram depicting the placement of the new species are provided.

During botanical observations made in the spring of 2021, in the area of Enisala Nature Reserve (Tulcea County), the species Lathyrus saxatilis (Fabaceae) was discovered, new for Romania and represented by a relatively large population. The article presents a detailed description of its morphological characters, together with the main seasonal characteristics and the coenotic environment in which the species grows there. At the same time, the conservation status of the population and its existing vulnerabilities are evaluated.

A New Species

Asian leaf-litter toads of the genus Leptobrachella represent charismatic anuran diversification with 80 species, of which 25 are from China. Recent new discoveries suggest that the diversity of this genus is underestimated. Here, we describe a new species of Leptobrachella, Leptobrachella bashaensissp. nov. from the Basha Nature Reserve, Congjiang County, Guizhou Province, China. The new species is distinguished from its congeners by the following suite of morphological traits: small body size (SVL 22.9–25.6 mm in six adult males and 27.1 mm in one adult female); head longer than wide; dorsal skin slightly shagreened with small tubercles; creamy-white chest and belly with irregular black spots; distinct ventrolateral glands forming a white line; finger webbing and fringes absent; toe webbing rudimentary and lateral fringes narrow; iris bicolored with bright orange in upper half and silver in lower half; dorsal surface of tadpole head dark brown with small, brown, irregular spot, air sac-shaped bulges on both sides of body. The new species differs from all known congeners by an uncorrected p-distance of >5.3% of the 16S rRNA gene fragment examined, and the phylogenetic analysis clusters the new species with L. maoershanensis and L. laui. At present, the new species is only known from a small range of montane evergreen secondary forests in Basha Nature Reserve approximately 900 m elevation. Its natural history and conservation status are discussed.

A new species of Hanguana (Hanguanaceae), H. thailandica, is described and illustrated from Trang province, Peninsular Thailand. This is the second Hanguana species recorded in Thailand, along with the widespread helophytic H. malayana. The species is morphologically similar to Hanguana exultans and H. nitens found in swamp forests habitats in southern Peninsular Malaysia and Singapore. The conservation status of this species is accessed as Endangered according to the IUCN Red List Category and Criteria.

Abstract—A new species of Eugenia from the Atlantic forest of Brazil is described and illustrated. Eugenia flavicarpa is restricted to the Floresta de Tabuleiro (lowland forests) of Espírito Santo state and is nested in Eugenia subg. Pseudeugenia. Considering all other species of the subgenus that occur in forest vegetation types of the Atlantic forest phytogeographic domain, Eugenia flavicarpa can be distinguished mainly by the combination of smooth leaves with indumentum on both surfaces, with two marginal veins, usually ramiflorous inflorescences, pedicels 4.5‐9.7 mm long, flower buds 3.5‐4 mm in diameter, and by the calyx lobes that are 2‐3 mm long with rounded to obtuse apices. Morphological analyses were performed to explore the significance of quantitative diagnostic features between the new species and the closely related species, Eugenia farneyi. Notes on the habitat, distribution, phenology, and conservation status of Eugenia flavicarpa are provided, as well as a key for all species of Eugenia subg. Pseudeugenia from forest vegetation of the Atlantic forest phytogeographic domain.

Scrophularia dianatnejadii Ranjbar & Rahchamani, a new species from Tehran Province in northern Iran, is described and illustrated. It is closely related to S. amplexicaulis Benth. and shares with it some diagnostic morphological characters such as habit, plant indument, phyllotaxy, and corolla shape and color. Both species are placed in Scrophularia L. sect. Mimulopsis Boiss. Macro- and micromorphological characters of the two are examined and compared. Pollen morphology of these species is investigated using SEM. Detailed descriptions, illustrations, distribution maps, and conservation status of both species are provided.

Silene lulakabadensis Heidari, F. Ghahrem. & Assadi is described as a new species from Zanjan Province, Iran. The new species is a dark green plant, perennial and woody at the base, that was collected on marl soil slopes at 2100 m. It is believed to be closely related to S. eriocalycina Boiss. from section Auriculatae (Boiss.) Schischk. but is a smaller plant, with much shorter internodes, and pinkish-white retuse to emarginate petals with very small or no scales. It is a very rare plant and its conservation status is assessed as Critically Endangered.

A New Species

Beaucarnea olsonii is described and illustrated from tropical deciduous forests of SW Puebla, Mexico. The new species can be distinguished from other Beaucarnea species by its massively swollen base that abruptly tapers into slender branches, by its conspicuously long stigma, and by its pedicel articulation that occurs at 2/3 of the length of the pedicel below the flower. With this new addition, the total number of endemic species of Beaucarnea for Mexico increases to 10, making this country the greatest center of diversification and endemism for the genus. We also provide a distribution map and a conservation status recommendation for the new species, as well as a key to the Beaucarnea species of southern central Mexico.
