Sonerila bokorense, a new species of Melastomataceae from Cambodia, is described and illustrated. The new species is similar to S. calophylla, but it is distinguished by having aggregated tubercles, narrower leaves, and glandular trichomes on the pedicels, hypanthium, mid-veins of abaxial petals, and capsules.

A New Species

During a floristic survey of Melastomataceae carried out in Delfinópolis and Capitólio, Minas Gerais State, Brazil, a new species of Fritzschia was found. Fritzschia furnensis has stems peeling in thin, woody flakes, petiole 2–10 mm long, large leaf blades (23–38 × 10–29 mm) and an indumentum of glandular trichomes on the branches, petioles, leaves, bracteoles, pedicels, hypanthia, and sepals. The new species is regarded as endangered (EN) due to a restricted distribution, small populations and the destruction of its habitat.

Lessingianthus concepcionis, a new species from northern Paraguay is described and illustrated. The new species has a certain resemblance to L. niederleinii but can be easily separated by the combination of leaves with denticulate and revolute margins, tomentose beneath, involucre with 6–7 series of phyllaries, glandular trichomes on the corolla lobes, and the chromosome number 2n=8x=128.

A new species, Asarum koreanum (Aristolochiaceae), is described from Mount Gaseopsan, in Eumseong-gun, Chungcheongbuk-do, Korea. It is differentiated from the morphologically similar A. sieboldii, by the purple or light green leaves without white variegation, large flowers, and deep purple calyx lobes with dense multicellular glandular trichomes. In addition, this species only occurs in the Baekdudaegan mountain range of the central part of Korea (Chungcheongbuk-do), whereas A. sieboldii is extensively distributed throughout Korea, Japan, and China.

During our analyses of Lycianthes exsiccates, as part of the taxonomic treatment for the Brazilian flora, a new species was discovered and is described and illustrated here. The species is compared and contextualized within the infra-generic classification of Lycianthes. Analyses of indument and trichomes were performed by stereomicroscopy (SM) and scanning electron microscopy (SEM). The new species, Lycianthes amazonica, is recognized as an endemic species to the Brazilian Amazon, which has its habitat described as secondary formations (capoeira) of terra-firme forests. It is closely related to L. sprucei, with which shares the scandent or vine habit, flexuous branches and ferrugineous indument of glandular trichomes. However, they are distinguished by several morphological features, including trichomes morphology, a sessile inflorescence and calyx appendages of equal length; both species belong to Lycianthes. subg. Polymeris sect. Eulycianthes ser. Glanduliferae. The description of this species expands the total number of Lycianthes species to the Brazilian Amazon to six, as well as thirteen to Brazil. The affinities of Lycianthes amazonica with its related species, distribution, ecology, and conservation status are discussed. Additionally, a lectotypification of Lycianthes sprucei, a species closely related to L. amazonica, is proposed.

A revisional taxonomic study of Adesmia subg. Adesmia ser. Bicolores has unveiled a new species from southern Brazil. Adesmia miottoae is described and illustrated here. Its geographic distribution, phenology, conservation status and morphological similarities with its closest relatives, Adesmia punctata and A. incana, are presented. The species is distinguished by glandular trichomes covering all the aerial parts of the plant, except the corolla. These trichomes are shorter than those of Adesmia punctata. Additionally, a detailed anatomical description of the leaflet blade is provided.

Microlicia furnensis, a new endemic species from campos rupestres of Capitólio municipality, Minas Gerais state, Brazil, is described and illustrated. The new species is characterized by its cream petals with pale pink blotches at the apex, sessile or subsessile leaves and golden glandular trichomes and short pale trichomes covering the leaves, pedicels, hypanthium and the calyx lobes. It resembles M. confertiflora, M. isophylla and M. flava, the latter also occuring in Capitólio, Minas Gerais state. A list of species of Melastomataceae from the mountains of Capitólio municipality is also provided.

A new species of Asteraceae, Saussurea odorata, is described here based on morphological evidence. The new species was discovered in the southern part of the Mongolian Altai Mountains, Möst Sum (District), Khovd Aimag (Province), Mongolia. Morphological comparisons showed that S. odorata is similar to S. saichanensis and S. krylovii, but can be distinguished by its much-branched caudex, a larger number of capitula in a dense racemose synflorescence, and a strong odor due to the high density of glandular trichomes on both surfaces of leaves. Detailed illustrations, pictures of living plants, as well as a key for identification are presented.

A New Species

Malesherbia fatimae is described as a new species from the Province Condesuyos, Department of Arequipa, Peru. The new species is clearly differentiated from all know species of the genus by forming a strictly erect, laxly branched shrub with densely tomentose indument and from the perennial Peruvian members by an absence of the glandular trichomes. No clear affinities to know species present themselves, but the new species evidently belongs to Malesherbia sect. Malesherbia. At the type locality a putative hybrid with the morphologically highly divergent Malesherbia tenuifolia was observed, showing morphologically intermediate characters between M. fatimae and M. tenuifolia. Malesherbia tenuifolia is here for the first time reported from Peru, bringing the species total for the county to 12. A second putative interspecific hybrid, Malesherbia ardens × M. arequipensis, is reported from Department Moquegua. This indicates that species of Malesherbia may hybridize when eco-geographical separation breaks down due to habitat modification. The new species and the two novel hybrids are described and illustrated.
