A new species of Boesenbergia, B. ashihoi Suparna, Sameer Patil & V.Deepu is described from Lumdiengsai, Meghalaya, India. Boesenbergia ashihoi resembles B. siphonantha (King ex Baker) M.Sabu, Prasanthk. & Škornick. and B. tillandsiodes (Baker) Kuntze in bearing a small globular rhizome, long‐petioled leaves, horn‐like spike and anther connectives without crest, but differs in having elliptic leaves (versus oblong‐lanceolate), bracteoles much shorter than bracts (versus almost equalling bracts), labellum orbicular with orangish throat (versus ovate to obovate or cuneate with reddish or yellowish throat), and corolla tube 9–10 cm long (versus 1–6 cm long). The new species is described and illustrated in detail. A key to species of Boesenbergia in India is provided.

A new heterotrophic dinoflagellate, Protoperidinium vietnamicum sp. nov. is described from the coastal waters of Vietnam. It is characterized by an elongated, pentagonal to pyriform body in ventral and dorsal view, with moderate dorsoventral compression. Epitheca is tapering into a robust apical horn, which is shorter than the antapical horns. Cingulum is equatorial, descending by about 0.50–0.75 of its width. Sulcus is wide, shallow, and slightly oblique. Plate 1′ is ortho‐type, and intercalary 2a and 3a plates are pentagonal. Plate 1a is quadrangular, having approximately one third the area of plate 3a. Additionally, the new combination Protoperidinium curvicorne (Böhm) comb. nov. is proposed. It is a large cell‐sized species with a round, broad body, and strong dorsoventral compression. Its epitheca narrows abruptly into a slender apical horn strongly tilted towards the ventral side. The cingulum is narrow, shallow, descending by about 1.5–2.0 cingular widths, and strongly inclined relative to the equatorial plane of the cell. The plate 1′ is ortho‐type, and 2a and 3a are pentagonal. Specimens from the type locality of the taxon were examined. Both species are provided with detailed descriptions and are illustrated with line drawings, as well as with light microscopy images and SEM micrographs. An in‐depth discussion and comparison with similar species are presented.

The genus Sorbus s.l. consists of small to medium‐sized trees primarily found in coastal areas, with three European hotspots of diversification: Fennoscandia, south‐east Europe and the British Isles. Taxonomic classification of Sorbus s.l. in Europe is still unresolved, and this study aims to address this issue by examining the pollen morphology of various Sorbus hybrids. Pollen morphology of 16 specimens from 13 species of Sorbus s.str., Aria and Hedlundia, some of them common, others are endemic and listed as threatened species, were studied. Measurements of the polar and equatorial axis of all pollen grains show that there are variations in pollen size and shape among different hybrids, with a correlation between ploidy levels and the equatorial diameter of the pollen. Surface structures of the pollen were observed using SEM. Principal component analysis (PCA) was performed to analyze the pollen characters, and the results show that it is possible to separate Aria from Sorbus and Hedlundia based on the length of the polar axis of the pollen grain, while the number of perforations is important for classification within Hedlundia. The study concludes that pollen morphology can be a useful tool for distinguishing between different Sorbus hybrids and can thus aid in understanding their past distributions.

Euploca wightiana P.Javad & Ancy sp. nov., a new species of the family Heliotropiaceae is described from the Coimbatore district of South India. Morphologically, it is close to Euploca marifolia but differs in having erect (versus prostrate) habit, stem woody throughout (versus stem woody only at base) with dense hairs (versus sparsely hairy), oblong leaves (versus lanceolate) with obtuse apex (versus acute), inflorescence with distantly placed flowers (versus inflorescence with closely placed flowers), a 0.6 mm long cylindrical style (versus style less than 0.3 mm long), a unifid, capitate stigma (versus bifid, conical) and densely hirsute nutlets (versus minutely hairy or glabrous). Detailed descriptions, photo plates, and distribution maps are provided. Differences from morphologically allied congeners are discussed. The status of the new species is provisionally assessed here as ‘critically endangered (CR)' following the IUCN red list categories and criteria.
