Polysporangiate anthers described in Eugenia (Myrtaceae) with notes on evolutionary patterns.
Shifts towards compartmentalisation resulting in multilocular anthers have been described in some families of Myrtales but to date, not in Myrtaceae. In these other families sporogeneous tissue is partitioned by transverse or longitudinal septa, fitting the definition of the ‘polysporangiate anther’. Polysporangiate anther in Eugenia, a Neotropical genus of Myrtaceae... -

On the identity of Dracocephalum breviflorum (Lamiaceae, Nepetoideae).
As currently circumscribed, the genus Dracocephalum Linnaeus (1753: 594) includes the traditionally defined Hyssopus Linnaeus (1753: 569) and Lallemantia Fischer & Meyer (1840: 52), making it the second largest genus in subtribe Nepetinae (Nepetoideae, Lamiaceae), consisting of ca. 80 species (Chen et al. 2022). Morphologically, the genus is most similar... -

A new combination in Handroanthus (Bignoniaceae) from Brazil.
While reviewing Vellozo’s Bignoniaceae names in Floræ Fluminensis, a nomenclatural novelty came to light. The name Bignonia longiflora Vellozo, being a later homonym of B. longiflora Cavanilles, was deemed illegitimate. Consequently, Vellozo’s name was eventually replaced with Tecoma speciosa Candolle ex Martius. However, when Tabebuia Gomes ex Candolle was considered... -

Diversity partitioning and community structure of epiphytic bryophytes along an elevational gradient in the north-eastern Madagascar.
Understanding spatial variation in species composition of different communities is key to understanding the processes that generate and maintain biodiversity. The partitioning of diversity into hierarchical scale-related components is an interesting approach to quantitatively defining the overall net biodiversity from hierarchically scaled studies and is a useful method in studies...Marline, Lovanomenjanahary ; Hedderson, Terry A.

An enlarged circumscription of Bifrenaria (Orchidaceae: Maxillariiinae).
A revised delimitation of Bifrenaria broadens the genus to include the previously accepted genera Guanchezia, Horvatia, Hylaeorchis, Rudolfiella, Scuticaria, and Teuscheria. These genera as currently circumscribed are changed to sections, and their respective species transferred or combined along with newly synonymised species. Bifrenaria sect. Stenocoryne and B. sect. Adipe are...Meneguzzo, Tniago E. C. ; Chase, Mark W.

A new species of Byttneria sect. Crassipetala (Malvaceae, Byttnerioideae) from Eastern Amazonia.
Byttneria (Malvaceae, Byttnerioideae) is a Pantropical genus known for its variable growth forms—ranging from shrubs to lianas—and complex floral structures. In this study, we describe a new species, Byttneria filifolia Gerace & Colli-Silva, from B. sect. Crassipetala, found in the Eastern Amazon rainforest of Brazil, specifically in Pará, and Mato...Gerace, Samuele ; Colli-Silva, Matheus
