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.

Allium shahinii, a new species of Allium sect. Scorodon, is described and illustrated from Erzincan Province, Eastern Turkey. It is a narrowly distributed geophyte growing on siliceous screes of warm exposure in mountain ranges of the nemoral and thermophilous deciduous woodland zone, showing close morphological relationships mainly with A. moschatum, A. stocksianum, A. spirophyllum, A. circumflexum but it is clearly differentiated due to perigon, outer tunic, indumentum, leaf and scape characteristics. In this study, diagnostic characters, description, taxonomic comments, photographs, distribution map, detailed illustration, the conservation status of A. shahinii and identification key are provided for A. shahinii and related taxa. According to IUCN Red List Categories and Criteria, A. shahinii is assessed here as a Critically Endangered (CR) species.

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.

Hemiboea chanii, a new species of Gesneriaceae from Ha Giang Province, northern Vietnam, is here described and illustrated. It has many branched stems, diamond-shaped involucre with two cirrose opposite apices, a pink corolla, red spotted inside, and a flowering time in January-February. Among congeners with an externally hairy corolla, this new species is morphologically close to H. crystallina and H. sinovietnamica. Diagnostic discriminative characters in all mentioned species are discussed. The conservation status of this species is considered to be “Critically endangered” (CR) according to the IUCN Red List Categories and Criteria.
