Populus luzae, a new species of white poplar from the western Transmexican Volcanic Belt, Zapopan, Jalisco, Mexico, is described and illustrated. Populus luzae belongs to section Populus and is morphologically close to P. guzmanantlensis, but it differs from the latter in having smaller size and soboliferous habit, narrower twigs and petioles, ovate to ovate-deltoid and chartaceous leaf blades, adaxial leaf surface with less depressed veins, abaxial surface puberulent, thrice smaller ovate male bracteoles with entire margin, twice longer female bracteoles sparsely denticulate but none lobed, smaller number of pistillate flowers, capsules pubescent, twice longer mature male inflorescence, and a lax and longer infrutescence.

A New Species

In the course of a taxonomic revision of Miconia sect. Lima, we discovered a previously undescribed species, Miconia paralimoides, from the Cordillera Central, Dominican Republic. This species is part of the Miconia lima species complex, and is most similar morphologically to Miconia limoides. We illustrate and provide a distribution map of the species, as well as a key to distinguish M. paralimoides from other members of the Miconia lima complex, i.e., species with very well-developed, bulla-based hairs on the adaxial leaf surface, which mostly or completely cover the areoles.

Abstract. A new species and a rediscovery in the genus Saurauia (Actinidiaceae) from Zamboanga Peninsula, Mindanao island, Philippines are presented here. The new species, Saurauia abbreviata, closely resembles Saurauia lanaensis Merr. but can be differentiated by having longer petioles, uniformly setose adaxial leaf surface, longer and wider leaves, more lateral veins, 3 styles, and a 3(–4)-locular ovary. This discovery raises the current number of recognized Saurauia in the Philippines to 57 following an 87-year gap in the taxonomic study of this genus in the country. S. longipedicellata Merr. is also rediscovered after almost a century. A lectotype is here assigned for this name selected among the syntypes. Photographs, ecological notes, and an amended description are also provided to aid taxonomic identification.   Abstrak. Usa ka bag-ong species ug nadiskobrehan pag-usab sa genus nga Saurauia (Actinidiaceae) gikan sa Zamboanga Peninsula, isla sa Mindanao, Philippines ang gipresentar dinhi. Ang bag-ong species, Saurauia abbreviata, nahisama pag-ayo sa Saurauia lanaensis Merr. apan ang bag-ong species adunay labi ka taas nga mga petioles, uniformly setose ang ilalom nga dahon, mas taas ug mas lapad nga dahon, labi pang mga lateral veins, 3 styles, ug 3(–4)-locular nga obaryo. Ang nadiskobrehan nagdugang sa kadaghanon sa mga giila nga Saurauia sa Pilipinas ngadto sa 57 human sa 87 ka tuig nga gintang sa taxonomic nga pagtuon sa kini nga genus sa nasud. Ang Saurauia longipedicellata Merr. nadiskobrehan usab pagkahuman sa hapit usa ka gatus ka tuig. Ang tipipikasyon gihimo dinhi aron mapalig-og ang ngalan. Mga litrato, mga notang ekolohikal, ug giusab nga hulagway alang sa maong species makita usab dinhi.

Surface Comparison

Study of selected specimens of Gymnomitrion collected by D. G. Long in Yunnan, China, revealed a new species, G. fissum Mamontov et Potemkin, sp. nov., with a fissured leaf surface. Comparison of SEM images of the leaf surface and leaf cross sections shows that the leaf surface of G. fissum is different from that of other known species with a superficially similar leaf surface, i. e. Mylia taylorii, M. verrucosa s. l. and Trabacellula tumidula. It has fissures around the cell lumen rather than grids and perforations. Outer cell walls of Gymnomitrion fissum are much thicker than in Mylia taylorii, M. verrucosa s. l. and Trabacellula tumidula, and their outer layers tend to be partly or completely caducous. G. fissum is related to the group of species assigned to the former genus Apomarsupella.

Valeriana iganciana, an endemic species from the Serra do Tabuleiro highlands of Santa Catarina state, southern Brazil, is described and illustrated. The new species shares morphological affinities with V. ulei, from which it is distinguished mainly by leaves with entire margin, by the cymose architecture of the inflorescence and by the triquetrous and elliptical fruits with annular to dentate calyx.

A new species of Bertolonia (Melastomataceae; Bertolonieae) endemic to the Brazilian Atlantic Forest is described and illustrated. Bertolonia organensis is known from only one locality in the Serra dos Órgãos National Park, state of Rio de Janeiro. The main diagnostic characteristics that distinguish B. organensis are the leaves with bullate adaxial surface and foveolate abaxial surface, cordate base and seven acrodromous veins, petiole and hypanthium glandulose-punctate, setulose and setulose-glandulose, the external calyx lobes erect, thick, narrow-triangular, apex acuminate-glandulose, margin entire, not ciliate, and the anthers connective dorsally appendaged, trilobed or with an acute calcar. Comparisons with similar species, geographic distribution and habitat are presented for the new species, as well as a key to identify all Bertolonia taxa known from the state of Rio de Janeiro. Bertolonia organensis is classified as Critically Endangered (CR).

A New Species

Miconia goldenbergiana, a new species from the Atlantic Forest in southeastern Brazil, is described and illustrated. The new species have been extensively collected since the end of the XIX century but have been confused with M. budlejoides and M. formosa, species that also have discolorous and suprabasal leaves and glomerulate inflorescences. From the first species, it can be distinguished by papyraceous leaves with the abaxial surface covered by lepidote trichomes. From the second species, it can be distinguished also by the texture of leaves, and by its narrower size, crenulate to serrulate margins and acute base, besides the smaller size of the flowers. The new species is known from the states of Espírito Santo, Rio de Janeiro and eastern São Paulo, and is in danger of extinction.

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

We describe a new species of gecko in the Lepidodactylus novaeguineae Group from Salawati Island, West Papua Province, Indonesia. The new species can be distinguished from all congeners by a unique combination of aspects of body size, shape, colouration, and scalation. The holotype and only known specimen is a mature male with a snout-vent length of less than 33 mm, suggesting it is the smallest species of Lepidodactylus; however, to confirm that, larger sample sizes of the nominate species and other species are required. The Lepidodactylus novaeguineae Group has a wide distribution across the western, northern, and eastern margins of New Guinea, but it seems to be most often associated with islands (including land-bridge islands) or geological terranes derived from former island arcs.
