A New Species

Begonia giganticaulis, a huge new species in Begonia sect. Platycentrum of Begoniaceae from southern Xizang (Tibet) of China, is described. Morphologically, it is mostly similar to B. longifolia and B. acetosella, but clearly differs from the former mainly by its dioecious and taller plants, sparse hairs on abaxial veins, longer inflorescence, unique shape of fruits, and differs from the latter mainly by its late and longer flowering time, 6-tepals of female flower and 3-loculed ovary. The phylogenetic analyses also support the separation of the new species from other taxa. Based on the current data, its conservation status is assigned to Endangered (B2a) according to the IUCN Red List Categories and Criteria.

A New Species

Two specimens of an apparently new Bulbophylum species were found in the Monts de Cristal, Gabon. They have a unique leaf shape among the species of this genus in Continental Africa. The flower shares the general morphology of Bulbophyllum saltatorium, one of the most common members of Bulbophyllum in Central Africa. Eight other taxa of the Continental African Bulbophyllum possess unifoliate pseudobulbs and long hairs on the lip. Comparison with them indicates that the new collections from Gabon represent a distinctive species, not yet known in the genus. We describe it here as Bulbophyllum pauwelsianum. The distinguishing features of the species include its leaves, which are pendant, coriaceous, linear, semiterete and v-shaped in transverse section, and its sepals, which possess relatively long hairs on their margins. A table of the taxonomic treatments of the nine Continental African Bulbophyllum taxa considered here is included. A taxonomic key and a table of the diagnostic characters of these nine taxa are given to facilitate identification. The new species is restricted to lowland forests of the Monts de Cristal in Gabon. A preliminary assessment of the conservation status, using the IUCN Red List Categories and Criteria is provided.

Abstract—Valeriana caparaoensis, a new species from the High Altitude Tropical Grasslands of Southeastern Brazil, is described and illustrated. The new species is known only from the Serra do Caparaó massif, between the states of Minas Gerais and Espírito Santo, Southeastern Brazil. It shares morphological affinities with V. catharinensis and V. polystachya, the first restricted to Brazilian Subtropical Highland Grasslands, and the last restricted to Lowland Grasslands of Southern Brazil, Uruguay and Argentina. Besides the great geographical disjunction, the new species differs from the other two species by the pinnately lobed proximal leaves, by the lanceolate distal lobes and longer pseudopetioles in distal leaves, by differences in the size of the flowers, and by the rounded to ovate and broader achenes. Additionally, we provide the preliminary conservation status assessments using IUCN Red List categories and criteria, as well as an updated checklist and a key for Valeriana species from Southeastern Brazil.

Mitreola crystallina was proposed in 2006, but not valid. Here, we validate the name by giving a complete description, diagnosis, and illustration as a new species of Loganiaceae. Morphologically, it is most similar to M. pedicellata, but can be distinguished by its stems erect (vs. creeping), corolla lobes blue (vs. white), and stamens inserted at or near base of the corolla tube (vs. middle to nearly mouth of corolla tube). It is endemic to the shady cliffs of limestone forests of Malipo County, southwest China. The conservation status was assessed as data deficient (DD) according to the IUCN Red List categories and criteria. And a key to species of Mitreola in China is provided.

A New Species

Here we describe Paraboea dolomitica Z.Y. Li, X.G. Xiang & Z.Y. Guo, a new species of Gesneriaceae from Guizhou, China. Based on recent extensive observations, this new species is morphologically similar to Paraboea filipes (Hance) Burtt, in having obovate leaf blades, 1–4-flowered cymes and purplish corolla, but differs from that species by the combination of denticulate leathery leaves, sparsely brown haired peduncles, two woolly bracts, reniform anthers and two glabrous staminodes. Additionally, molecular data support this new species as a member of a clade that includes P. crassifolia, P. tetrabracteata, P. peltifolia, P. vetutina, P. dushanensis, P. dictyoneura, P xiangguiensis and P. guilinensis, but it is distinct from them in leaf position, inflorescence, penduncle, bract and capsule. The conservation status of this species is considered to be “Vulnerable” (VU) according to the IUCN Red List Categories and Criteria.

Three New Species

Three new species of Lepanthes from Ecuador are described and illustrated. These additions to the Ecuadorean flora were recorded in evergreen montane forest and páramo as part of three different research projects conducted during the last five years (2016–2021). Lepanthes oro-lojaensis was discovered in the southwest of El Oro province and is similar to L. jimburae, differing mainly in the much smaller plants, inflorescences and floral parts. Lepanthes microprosartima from the western slopes of Pichincha volcano in northern Ecuador resembles L. obandoi but differs in the coloration of the leaves, the inflorescence that are shorter than the leaves and the smaller floral appendix. Lepanthes caranqui, found in eastern Pichincha and Imbabura, is most similar to L. pachychila but differs from it in its much larger plants and different shape of the petals and the floral appendix. Preliminary assessments of the conservation status of the three taxonomic novelties are provided, using the IUCN Red List Categories and Criteria.
