Rubus prissanicus, a new regional apomictic species, is described from north-western Poland. It is similar to R. lindleianus and R. langei, however it differs from the former species by broader leaflets and less numerous prickles on the inflorescence axis, and from the latter by unequally serrate leaflet margin, and from both these species by different types of trichomes on abaxial leaflet surface. Unlike other Polish species of R. ser. Rhamnifolii, in which the indumentum of abaxial leaf surface consists mainly of branched hairs, simple trichomes are the main component of indumentum of R. prissanicus leaves. The new species has been observed mainly on fertile soils, in broadleaf forest habitats, usually in fairly sunny places, along forest margins, by forest roads, in clearings, and in wayside thickets.

Abstract Piresia, a small genus of herbaceous bamboos, has a geographical disjunction between the Caribbean and northern/western South America and the north-eastern Atlantic Forest in Brazil. Piresia leptophylla is reported from western Amazonia (WA) and the north-eastern Atlantic Forest (NAF), but its occurrence in western Amazonia is questionable. Using an integrative approach, we combined traditional morphological analysis, anatomy and niche modelling. The results revealed few macromorphological differences between WA and NAF specimens (only plant height, leaf length, lodicule dimensions, shape and position), contrasting with consistent differences in leaf anatomy (macrohairs and cruciform silica bodies in the costal zone of the adaxial/abaxial leaf surfaces, crenate silica bodies on the abaxial leaf surface, lack of panicoid hairs on the abaxial leaf surface, bicellular microhairs and lobed papillae over the abaxial leaf surface, and sparse but elongated fusoid cells in the mesophyll of WA specimens) and in niche patterns. The anatomical/micromorphological characters suggest environmental adaptations to the Amazonian and ‘restinga’ forests, respectively. We therefore propose the segregation of the WA populations into a new species, Piresia tenella sp. nov. We provide a formal description, photographs, a line illustration, a distribution map and discussion of the conservation status for the new species.

Paris lihengiana (Melanthiaceae), a new species from Yunnan Province, China, is described and illustrated based on evidence from morphological characters and molecular phylogeny. It differs from other species of Paris in its pubescent stem, pedicel and abaxial leaf surface, as well as other characters. Molecular phylogenetic analysis of 33 taxa in Paris was conducted based on nuclear ribosomal ITS and six plastid markers. Paris lihengiana is supported as a new species by both morphological characters and molecular data.

We here describe and illustrate Begonia tadungensis (B. sect. Platycentrum), a new species from southern Vietnam. The new species is most similar to B. albopunctata in having broadly ovate leaves, three free styles, 4-loculed ovary, and berry-like fruits with a beaked apex, but differs mainly in having a glabrous abaxial leaf surface (not densely red pubescent), and fruits with gray puberlous hairs (not white papillose). It is also similar to B. pendens in its broadly ovate leaves and monoecious breeding system, but differs in having 6 tepals in the pistillate flowers (not 5) and 4-loculed ovaries (not 3-loculed). Information on ecology, conservation status, and a further comparison of characters with these two similar species is also provided.

A new taxon belonging to the genus Burmeistera (Campanulaceae, Lobelioideae) is described from El Quimi Biological Reserve in Morona Santiago Province, southeast Ecuador. Burmeistera quimiensis is characterized by its red-violet stems and veins, spiral phyllotaxy, bullate, ascending leaves with a revolute margin, puberulous abaxial leaf surface, cupuliform hypanthia, and thick-walled white to red-violet fruits with reflexed pedicels. Photos of the new species are given, as well as a distribution map of known collection localities, and its relationships with other species are discussed.

Abstract The epicuticular wax layer of Humulus lupulus contains homologous series of hydrocarbons, wax esters, benzylacyl esters, aldehydes, primary alcohols, fatty acids and the triterpenoids β-amyrin, α-amyrin both free and esterified with long chain fatty acids and also friedelanone. At 54%, primary alcohols form the largest component. No single class of lipids forms a pre­dominant component (i.e. more than 80%) of the wax layer. Under scanning microscopical examination, both upper and lower surfaces of H. lupulus leaves appear covered by a continuous way layer which is devoid of any sculpturing or crystalloids. Epidermal cells are arranged in dense lamellate or undulate cuticular folds. Four different types of trichomes were identified on the surfaces of hop leaves and tendrils. The adaxial leaf surface bears numerous single, uni­ cellular, silicified, pointed hairs as well as many glands. On the abaxial leaf surface there are very long pointed hairs arising only from the veins. Hairs on the hop tendrils arise from the veins but are completely different in shape having two sharp points extending at right angles to the hair-base.

Litsea dorsalicana, a new species of Lauraceae from northern Guangxi, China is described and illustrated. It is similar to Litsea elongata, but can be distinguished from the latter by twigs, buds and abaxial leaf surface densely covered with gray-white pubescence, leaf blade oblanceolate to oblong, to 29.5 cm long, 10.5 cm wide, base cuneate to attenuate, fruit red, cupule cup-shaped, once or twice cleft at the margin.

A new species named as Lasianthus halconensis from Mt. Halcon, Mindoro, Philippines is described and illustrated. This species is easily distinguished from the other Lasianthus by having strigose indumentum on branches, abaxial leaf surface, petioles and calyx; lanceolate leaves, cuneate at base; obconical calyx and drupes with 8 pyrenes. This species is allied to L. obliquinervis and L. chrysoneurus but differs in stem, leaf and calyx indumentum, leaf and calyx shape and the absence of bracts. Moreover, three new records of Lasianthus in the country are reported including their diagnosis.

Four new species of Caraipa (Calophyllaceae) are described and illustrated: Caraipa balbinensis, endemic to Balbina (Presidente Figueiredo, Amazonas, Brazil), C. caespitosa growing in savannah and white-sand vegetation in Roraima and Amazonas (Brazil), Guainía (Colombia) and Amazonas (Venezuela), C. davilae, an endemic species of Loreto (Peru), and C. macrocarpa, an endemic species to Guyana. Morphological comparisons with the similar taxa are provided for each new species: C. balbinensis can be distinguished from C. heterocarpa by its longer leaves and petioles, and its slightly rugulose fruit surface; C. caespitosa can be separated from C. grandifolia and C. longipedicellata by its distinguished habit, and its smaller leaves and inflorescences; C. davilae differs from C. balbinensis and C. grandifolia by its dense indument on the abaxial leaf surface, and its rugulose and concave fruit valves; and C. macrocarpa can be distinguished from C. punctulata by its large, glabrous and rugulose fruits.

The present report provides information on 20 pontoniine shrimp taxa from the island of Socotra, collected by Dr Michael Apel, including two new species, of the genera Dactylonia Fransen and Periclimenoides Bruce. Thirteen species are reported from Yemen for the first time, 8 are newly recorded from the north western Indian Ocean. The record of Periclimenoides is the first occurrence of this genus in the western Indian Ocean. The number of pontoniine shrimps known from the north west Indian Ocean is now increased from 32 to 44 taxa.

Taiwan is a large island in north western Pacific waters with the sea floor connecting to two major deep-sea basins, the eastern waters facing the Pacific Ocean (to 4000 m depth) and linking to the Philippine Basin, whilst south western waters are associated with the South China Sea Basin (up to 1000 m). Previously, the biodiversity of Taiwanese deep-sea barnacles had not been studied extensively, due to a lack of deep-sea expeditions and sampling. Recently, several TAIWAN deep-sea cruises investigated the biodiversity of the deep-sea fauna of Taiwan and sampling was conducted to depths of 4000 m. The present study reports on the biodiversity of the deep-sea barnacles of Taiwan, a total of 18 species. One species was previously recorded from Taiwanese waters and 17 are new records, including two new species belong to the genera Litoscalpellum and Altiverruca.
