**Taxonomic revision of Brazilian species of Notylia Lindl. (Orchidaceae: Oncidiinae)**

2025-07-22T09:51:47+12:00

A taxonomic revision of Brazilian Notylia is presented. Among the 33 binomials evaluated, 14 are recognized as species, with only two endemic to the country. Notylia tenuis is re-established at species level, and N. fragrans is confirmed as an accepted name. Descriptions, identification key, photographic plates, illustrations, distributions, taxonomic notes and conservation status (for just the endemic species) are presented. Additionally, a lectotype is designated for N. microchila.

Guzmania tayuensis (Bromeliaceae) a new, very small, Tillandsia-like species from Amazonas, Peru

2025-10-03T09:03:37+13:00

A rare new Guzmania species is described, illustrated and compared with its morphological most similar species, Guzmania angustifolia (Baker) Wittmack (1889: 62). This in appearance Tillandsia like species grows terrestrial or saxicolous on rock of a small mountain range in northern Peru. It has a brown seed appendix (pappus) and the sepals distinctly connate into a tube, that places it in this genus. It differs from all other Guzmania species by its very short and narrowly triangular and cinereous lepidote leaf blades, relatively long caulescent habit and terrestrial growth (not seen in other small species).

Bellevalia baskilense (Asparagaceae, Scilloideae), a new species from Türkiye

2025-12-03T15:00:49+13:00

Bellevalia baskilense, defined as a new species from Baskil District (Elazığ), is known from a single locality. Since flower bud and perianth color and pedicel characteristics are very important for species identification of Bellevalia genus members; the changes in the inflorescences of the samples were followed until the fruits ripened and their photographs were taken. In this study, the diagnostic characters of the new species are discussed and taxonomic evaluations are presented. Although the new species has some similarities with Bellevalia speciosa and B. glauca species; it differs significantly from these species in terms of its leaf characteristics and dark violet to purplish violet flower buds, the abundance of flowers in its inflorescence, the pedicel length during flowering being 1.5–2 times the flower length, the perigon segments being as long as the tube length. Its photographs of the habit, bulb, scape and raceme and flower bud structures were taken using a camera and images of flowers and flower parts were taken from an binocular microscope for higher magnification. In addition to the ecological data, IUCN conservation status and distribution map of the new species, the distributions of related species are also given.

**Hidden in plain sight: historically overlooked Fissidens curvatoinvolutus and the Japanese endemic F. pseudoadelphinus newly recorded in China**

2026-01-08T11:33:24+13:00

Fissidens curvatoinvolutus and F. pseudoadelphinus are reported as new additions to China. Previously, F. pseudoadelphinus was only known from Japan. Fissidens curvatoinvolutus, often confused with F. involutus, can be distinguished by its smaller size, crenulate leaf margins, and slightly asymmetrical capsules. Fissidens pseudoadelphinus closely resembles F. teysmannianus, but differs in having narrower, frequently falcated leaves, and a costa that ends far below leaf apex. Detailed photographs, morphological descriptions, and comparisons with similar species are provided.

Impatiens chakhesangiana sp. nov. (Balsaminaceae)—a new species from Nagaland, India

2025-10-22T19:28:23+13:00

A new species Impatiens chakhesangiana sp. nov., is described and illustrated from Porba village, Phek district, Nagaland, Northeast India. It is similar to Impatiens drepanophora but, differs in multiple characters like perennial habit, stem, petiole, spur, dorsal petal, basal lobe and capsule. A distribution map is also provided.
