Lysimachia kraduengensis (Primulaceae), a new species from northeastern Thailand.
A new species of Primulaceae from Thailand, Lysimachia kraduengensis, is described and illustrated. It is morphologically similar to L. engleri, L. lancifolia, L. laxa and L. sikokiana in having solitary and axillary flowers, a yellow corolla, relatively long pedicels and basifixed anthers. The new species can be distinguished by the...Lysimachia, Eudicots, Molecular phylogeny, Thailand, Ericales, New species, Indo-China, Taxonomy, and Loei Province (Thailand)

A new species of Euploca (Boraginales: Heliotropiaceae) from the Inter-Andean dry valleys of Bolivia.
Euploca riochiquensis is described and illustrated as a species new to science endemic to the Rio Chico valley in Chuquisaca, Bolivia. Morphologically it resembles E. lagoense in its solitary axillary flowers but differs conspicuously in its shrubby habit. Its phylogenetic position, conservation status and distribution are discussed.Bolivia, Euploca, Endemic species, Xerophytic vegetation, Molecular sequence data, Taxonomy, Andes, and Eudicots

A revision of the neotropical Mucuna species (Leguminosae—Papilionoideae).
The genus Mucuna comprises approximately 105 tropical and sub-tropical species, with the highest diversity occurring in the Paleotropics. In the Neotropics, 13 new species have been described recently and a number of regional floras have been published. A recent floristic treatment for Colombia has summarized the Mucuna species found in...Mucuna, Eudicots, Systematics, Neotropics, Fabaceae, and Taxonomy

Revisions in Nepenthes following explorations of the Kemul Massif and the surrounding region in north-central Kalimantan, Borneo.
An expedition to the highest peak of the Kemul Massif located a number of different Nepenthes taxa, including the type populations of N. fusca Danser and N. mollis Danser (Nepenthaceae), neither of which have been observed in situ since they were first collected from Kemul in 1925. Studies of the...Eudicots, Nepenthaceae, New species, Indonesia, Non-core Caryophyllales, Taxonomy, and Malesia

Systematics studies in Pliniinae (Myrtaceae) necessitate two new combinations in Eugenia (Myrtaceae).
Although Eugenia and Plinia genera belong to different subtribes in Myrteae (Myrtaceae), shared morphological features have led to frequent mistaken identity to these species. Molecular phylogeny and morphological studies in Plinia show that Plinia martinellii and Plinia sebastianopolitana should be combined within the generic concept of Eugenia. In addition, two...Stadnik, Aline ; Caldas, Diana K.D. ; Souza, Marcelo C. ; Lucas, Eve J. ; Baumgratz, José Fernando A. …

Taxonomic monograph of Eugenia sect. Schizocalomyrtus (Myrtaceae: Myrteae), a group within Eugenia with unusual flowers.
Taxonomic monograph of Eugenia sect. Schizocalomyrtus, supported by molecular and morphological evidence, is presented. The flowers of this section have unusual fused calyces that are contrasted with standard Eugenia flowers with free calyx lobes. Because the fused calyx recurs in Myrtaceae and has been historically misleading for taxonomists, a key...Giaretta, Augusto ; Lucas, Eve ; Sano, Paulo Takeo

Myrcia excelsa (Myrtaceae), a new species from Espírito Santo, Brazil.
Myrcia De Candolle (1827: 401) (Myrciinae, Myrteae, Myrtaceae) is represented by 101 species in the Brazilian state of Espírito Santo (Santos et al. 2020). In addition, a new endemic species is here proposed based on a unique combination of morphological features. Morphological terminology follows Radford et al. (1974) and Lucas...Gaem, Paulo Henrique ; Fernandes, Thiago ; Sampaio Valdemarin, Karinne ; Lucas, Eve ; Mazine, Fiorella Fernanda

Three new species of Myrcia sect. Myrcia (Myrtaceae) from South America.
Three new species of Myrcia are described, illustrated and discussed. Myrcia rionegrensis from the Brazilian Amazon is related to M. clusiifolia from which it differs in having leaves with acute apex and ribbed fruits (vs. rounded apex and smooth fruits in M. clusiifolia); Myrcia microcalyx is similar to Myrcia scytophylla...Lima Dos Santos, Leidiana ; Vasconcelos, Thaís N.C. ; Ferreira de Sales, Margareth ; Lucas, Eve

A new species of Chamaecrista sect. Absus (Leguminosae, Caesalpinioideae) from Minas Gerais, Brazil, with Notes on Leaf Anatomy.
A new species of Chamaecrista was found in the Serra do Espinhaço region in the state of Minas Gerais, Brazil, during an expedition to study the taxonomy of this genus. Chamaecrista sempreviva Fort.-Perez & L.C. Zeferino sp. nov. is herein described, illustrated, and assigned to Chamaecrista sect. Absus. Comments about...
