A new species of Impatiens L. from Hubei, China, I. dasyvexilla Q. L. Gan & X.W. Li, is described and illustrated in this paper. This species is closely allied with I. blepharosepala E. Pritz. in having leaves that are crowded at the upper part of the stem and lateral sepals that are ciliate at the margin. However, I. dasyvexilla is distinctive in its hirsute dorsal petal, conical glands at the leaf base, densely pubescent pedicel, and distal lobe of united petals cleft at the inner side. This new species should belong to Impatiens sect. Impatiens.

Sonerila cardamomensis, a new species of family Melastomataceae from the Central Cardamom Protected Area in Koh Kong province of southwestern Cambodia, is described and illustrated. The species is similar to S. violifolia Hook.f. ex Triana, but is readily distinguished by its cordate leaf base, lack of setae at the nodes, longer pedicels, smaller petals, smaller hypanthiums and smaller capsules.

A New Species

A new species of Quercus (Fagaceae), Q. ngochoaensis, from Ba Vi National Park, Ha Noi, northern Vietnam is described and illustrated. This species is morphologically similar to Q. glauca in having glabrous twigs, cuneate leaf base, two or three fruits per infructescence, almost entire margin of lamellate rings on cupule except the lowest three rings, slightly convex scar at the base of a nut. However, it differs from Q. glauca in having smaller leaves, cup-shaped cupule enclosing 1/2–2/3 of the nut, 7–8 lamellate rings on cupule, and subglobose nut. In addition to the description, DNA barcodes of the two partial plastid regions of matK, rbcL and the nuclear region of ITS of the new species are provided.

A New Species

A new species of Neckeraceae, Neckera serrulatifolia Enroth & M.Ji, is described from Xizang (Tibet), China. It belongs in an Asian group of relatively robust, distinctly stipitate species with an obtuse leaf apex, relatively long costa and strongly incrassate-porose leaf cell walls, but differs from the other species by the combination of strongly complanate and undulate branch leaves, long leaf decurrencies, and serrulate margins at leaf base and at midleaf. The sporophytes remain unknown.

The new species is morphologically congruent with Myrcia sect. Sympodiomyrcia and is apparently related to M. truncata, differing in its auriculate leaf base, shorter inflorescences and four calyx lobes. Additionally, a distribution map and conservation assessments based on IUCN criteria are provided.

Begonia scorpiuroloba sp. nov., a new species in Begonia sect. Platycentrum (Begoniaceae) from southern Guangxi of China, is described and illustrated. Morphologically, it is mostly similar to B. pedatifida, but differs clearly by its narrower lobes, denser hairs on leaf surface, obtuse angle of leaf base, subequal tepals of female flowers and late flowering. This new species is endemic to Guangxi and is assigned to Endangered (EN) according to the IUCN Red List Categories and Criteria.

A new species of the copepod genus Pseudovaigamus Amado, Ho & Rocha, 1984 is described herein based on parasitic adult females found attached to the gills of the freshwater teleost Pimelodus maculatus Lacepède, 1803, sampled in two tributaries (Veados and Paranapananema Rivers) of the Jurumirim Reservoir, Upper Paranapanema River, São Paulo State, Brazil. The new copepod was identified as an undescribed species of Pseudovaigamus because it shares with the type-species, Pseudovaigamus spinicephalus (Thatcher & Robertson, 1984), the combination of first leg with 2-segmented endopod, fourth leg with 3-segmented endopod and 2-segmented exopod, and cephalothorax armed with dorsolateral stylets (or retrostylets). However, the new copepod differs from its congener in having a trifid rostral spine, retrostylets with long spatulate process, 5-segmented antennule, and caudal rami simple or lacking any distal lobe. We erected a new species, Pseudovaigamus tridentatus n. sp.. It is the first report of a Pseudovaigamus found on a freshwater fish in Brazil.

A New Species

A new species of Ulota D. Mohr, U. larrainii, is described from the Aysén Region, southern Chile. The characters that discriminate the new moss are the prostrate habit, leaves not crisped, marginal cells of the leaf base differentiated in 1(2) rows, vaginula hairy, exostome of 8 pairs of orange, recurved teeth, endostome of 16 broad and hyaline segments, and large, multicellular spores. The new moss is illustrated and compared with similar taxa. In addition, the presence of multicellular spores in the genus Ulota is summarized and evaluated from an updated list of currently accepted species. Finally, the distribution, species richness and levels of endemism in the different regions where Ulota taxa occur are summarised and discussed with the help of a world map.

A New Species

We describe and illustrate the new species Paepalanthus thomasianus (P. subg. Platycaulon, Eriocaulaceae) from São Paulo, Brazil, and compare it with other morphologically similar species. P. thomasianus is characterized mainly by its leaf indumentum, composed by long multicellular trichomes. Undulations formed by the vascular bundles in the leaf surface and the wide ratio between the leaf base and the middle region of the leaf are also useful to recognize the species. The morphological variation, habitat, geographic distribution, and conservation status of this new species are discussed.
