| 12:34p | [Botany • 2025] Crawfurdia minuticalyx (Gentianaceae) • A New Species from Arunachal Pradesh, India
Abstract Crawfurdia minuticalyx, a new species of Crawfurdia (Gentianaceae) is described here from Arunachal Pradesh, situated in Eastern part of Indian Himalayan Region (IHR). This new species is unique in its very small calyx from its allied taxa. Morphologically, it shows close affinity towards C. speciosa Wall.; however, it can be differentiated by its much smaller leaves with entire margin; minute, non-splitted, calyx; relatively shorter corolla; stamens inserted below the middle of the corolla-tube, oblong anthers; short gynophore, and very short style. A detailed description and illustration are provided here along with comparative table of morphological characters, for easy identification. Keyword: Arunachal Pradesh, Crawfurdia minuticalyx, Crawfurdia speciosa, Indian Himalayan Region (IHR), novel species
Crawfurdia minuticalyx R.Maity, Debta & S.S.Dash, sp.nov. Diagnosis: Crawfurdia minuticalyx show close morphological affinity to C. speciosa Wall., but it can be differentiated by its much smaller habit; leaves with entire margin, and slightly flattened, 0.3–0.5 cm long petiole (vs crenulate leaf margin, and terete, 0.5–0.7 cm long petiole,); single bracteate flower (vs 2-bracteate flowers); 0.4–1.0 cm long pedicels (vs 1.0–6.0 cm long pedicels); 1–2 mm long, linear to narrow lanceolate bracts (vs 7–10 mm long, lanceolate bract); 0.2–0.5 cm long, ridged, campanulate, non-splitted calyx with 0.1–0.2 cm long, ovate to narrow ovate or lanceolate lobes (1.0–1.2 cm long, smooth, tubular calyx with split on one side, with 0.2–0.3 cm long, triangular lobes); 2.0–2.5 cm long, ... Etymology: The specific epithet “minuticalyx”
denotes very small or minute size of calyx which has been
observed in the specimen during study and makes this
species unique from other allied taxa Rohan Maity, Manas Ranjan Debta and Sudhansu Sekhar Dash. 2025. A New Species of Crawfurdia (Gentianaceae) from India. Taiwania. 70(3); 445-448. DOI: 10.6165/tai.2025.70.445 [07 July 2025] taiwania.ntu.edu.tw/abstract/2093 | ||||||
| 1:07p | [Funga • 2025] Lentinus saisamorniae (Polyporales: Polyporaceae) • A New edible macrofungus from northern Thailand
Abstract A new edible Lentinus species, described herein as L. saisamorniae, was collected from local markets and natural habitats in northern Thailand between 2019 and 2021. This species is characterized by its small to medium-sized basidiomata, white to yellowish-white pileus, broadly ellipsoid to elongate-shaped basidiospores, dimitic hyphal system, and hyphal pegs. Nonetheless, its longer basidia and smaller basidiospores make it distinguishable from L. cladopus. A molecular phylogenetic analysis of the combined internal transcribed spacer (ITS) large subunit (nrLSU) of nuclear ribosomal DNA, and RNA polymerase II large subunit (rpb1) sequences supported the monophyly of L. saisamorniae as a distinct lineage within the genus Lentinus. Therefore, this new species was introduced based on both morphological characteristics and molecular phylogeny. A full description, illustrations, color photographs, and a phylogenetic tree to show the placement of L. saisamorniae are provided. Comparisons between the new species and morphologically similar and related species are discussed.

| 1:57p | [Botany • 2024] Rhododendron mulyaniae & R. engelbertii (Ericaceae) • Two New Species of Vireya Rhododendron from Tambrauw, Papua, Indonesia
Abstract Two new species of Vireya Rhododendron, Rhododendron mulyaniae sp. nov. and R. engelbertii sp. nov. were discovered in Tambrauw, Papua, Indonesia. Rhododendron mulyaniae resembles R. angiense in that the scales under the leaf are dendroid, but differs in having elliptic to narrowly elliptic leaves, lacking hairs on petiole, having a tubular funnel shaped corolla. Rhododendron engelbertii resembles to R. carstensense in leaf shape but differs by having narrowly tapering leaf base, scales present on the petiole, and a corolla densely scaly on the outside. Detailed descriptions, illustrations and provisional conservation threat status of these newly described species are provided.
