A revision of Nertera (Rubiaceae) in Taiwan was carried out by classical taxonomic methods and the presence of two endemic species was confirmed. Only one species, misapplied as N. granadensis, had been reported in the second edition of “Flora of Taiwan”, but there were two additional endemic species in this genus: N. nigricarpa and N. taiwaniana confirmed. Nertera nigricarpa is characterised by the entire leaf, purple-black petals, black fruits and dark-purple seeds with raised striate. Nertera taiwaniana has leaves with undulated margins, yellowish-green petals, red fruits and yellow-white seeds without striate. N. granadensis is excluded from the flora of this Island.

Taxonomic Methods

The genus Chassalia (Gentianales: Rubiaceae-Palicoureeae) in Borneo is revised based on a morphological survey of herbarium specimens using classical taxonomic methods. The tribal placement and probable paraphyly of Chassalia as currently delimited is reviewed. Previously, four described species of Chassalia were known from Borneo, with only one endemic species, Chassalia psychotriformis I.M.Turner nom. nov. (≡ Cephaelis psychotrioides Valeton). A key is given to the 18 species of the genus recognised from Borneo in this study. In total, 14 new species are described, all of them endemic to Borneo. These are: Chassalia atropurpurea T.Y.Yu sp. nov., Chassalia beamanii T.Y.Yu sp. nov., Chassalia calamus T.Y.Yu sp. nov., Chassalia chewii T.Y.Yu sp. nov., Chassalia involucrata T.Y.Yu sp. nov., Chassalia kinabaluensis T.Y.Yu sp. nov., Chassalia lancifolia T.Y.Yu sp. nov., Chassalia lancifolioides T.Y.Yu sp. nov., Chassalia longipes T.Y.Yu sp. nov., Chassalia macrocarpa T.Y.Yu sp. nov., Chassalia muluensis T.Y.Yu sp. nov., Chassalia muscicola T.Y.Yu sp. nov., Chassalia northiana T.Y.Yu sp. nov. and Chassalia ramosa T.Y.Yu sp. nov. Circumscriptions and discussions are given for all Bornean species recognised. A morphological glossary for Asian species of Chassalia is provided. Three separate species groups are recognised, the Chassalia curviflora and C. javanica groups, represented by a single species each in Borneo, and a new informal group, the ‘Involucrate group’, which is proposed and circumscribed to encompass the majority (16) of the Bornean species. Proposals for further work on Asian Chassalia are given.

Hells Canyon

Two Upper Triassic sphinctozoan sponges of the family Sebargasiidae were recovered from silicified residues collected in Hells Canyon, Oregon. These sponges areAmblysiphonellacf.A. steinmanni(Haas), known from the Tethys region, andColospongia whalenin. sp., an endemic species. The latter sponge was placed in the superfamily Porata by Seilacher (1962). The presence of well-preserved cribrate plates in this sponge, in addition to pores of the chamber walls, is a unique condition never before reported in any porate sphinctozoans. Aporate counterparts known primarily from the Triassic Alps have similar cribrate plates but lack the pores in the chamber walls. The sponges from Hells Canyon are associated with abundant bivalves and corals of marked Tethyan affinities and come from a displaced terrane known as the Wallowa Terrane. It was a tropical island arc, suspected to have paleogeographic relationships with Wrangellia; however, these sponges have not yet been found in any other Cordilleran terrane.

Taxonomic Key

Hornstedtia microcheila Ridl. (Zingiberaceae; Alpinioidieae; Alpinieae) is a poorly-known endemic species in the Philippines. It has not been collected again since its description in 1909. In 2017, however, the species was rediscovered in the Mt. Mandalagan Range, Patag, Silay City, Negros Occidental, after a lapse of over a century. A new, amended and extended description of H. microcheila based on this new collection is presented herein. Typification, colour photographs, distribution data, ecological details as well as a taxonomic key to the different Hornstedtia species in the Philippines are also provided.

A Preliminary Assessment on the Herpetofaunal Diversity of the Taal Volcano Protected Landscape (TVPL), Batangas Philippines

The Taal Volcano Protected Landscape (TVPL) encompasses a prehistoric volcano caldera that caters to many documented endemic species. Although regarded as a unique area with the potential to house a diverse ecological community, biodiversity research in TVPL is still found wanting. The present paper aims to provide baseline information and increase research interests on the herpetofaunal diversity of TVPL, in light of its many undocumented terrestrial faunal species. Twelve study sites within the municipalities of Tanauan, Mataasnakahoy, and Balete were visited during survey trips from May to November 2015. A combination of transect and opportunistic sampling techniques were utilized, with morphometric data and sexual maturity recorded for each specimen collected. This preliminary survey provided 24 newly documented species of amphibians and reptiles occurring within TVPL. A total 10 frog species (from families Bufonidae, Ceratobatrachidae, Microhylidae, Dicroglossidae, Ranidae, and Rhacophoridae) and 14 reptile species (from families Agamidae, Gekkonidae, Scincidae, Varanidae, Acrochordidae, Colubridae, Elapidae, and Tryonychidae) were documented. Of the reptiles recorded, 3 are endemic species and widespread throughout the Philippines: Gekko mindorensis, Hydrosaurus pustulatus, and Draco spilopterus. Also recorded were the Philippine endemic frogs Kaloula picta and Limnonectes woodworthi along with the Luzon endemics Platymantis mimulus and Varanus marmoratus. The species-effort curve of amphibians showed a distinct plateau whereas the species-effort curve of reptiles has shown an increasing trend suggesting that additional sampling efforts should be done in the area to further increase knowledge of the TVPL herpetofaunal diversity.

The confirmed freshwater fishes of Iran comprise 202 species in 104 genera, 28 families, 17 orders and 3 classes found in 19 different basins. There are also 23 species whose presence in Iranian waters needs confirmation by specimens. The most diverse order is the Cypriniformes with 120 confirmed species (59.4%) followed by Perciformes with 28 species (13.9%), Cyprinodontiformes (10 species, 5.0%), Clupeiformes (9 species, 4.5%), Salmoniformes (7 species, 3.5%), Mugiliformes and Siluriformes each with 6 species (3.0%), Acipenseriformes (5 species, 2.5%), Gasterosteiformes (3 species, 1.5%), and 8 other orders each with one species (0.5%). New species are still being discovered, 7 described in 2009, while others are being resurrected from synonymy, newly recorded from Iran, or exotic species newly established. Some taxonomic problems remain and are commented on briefly. Thirty-nine endemic species (19.3%) in 6 families and 23 exotic species (11.4%) in 8 families are listed here. The mosquitofish, Gambusia holbrooki Girard, 1859 is the most widespread exotic species.

Morphological Differences

There are seven endemic species of Boswellia Roxb. ex Colebr. on Socotra Island, Yemen. Boswellia socotrana Balf. f. is a culturally, economically, and ecologically important species on the island. The name Odina aspleniifolia Balf. f. has been considered as a synonym, but there are morphological differences between the two taxa sufficient to justify their distinction at subspecific rank. Therefore, O. aspleniifolia is transferred to Boswellia as B. socotrana subsp. aspleniifolia (Balf. f.) Lvončik. A lectotype is designated for O. aspleniifolia. The distribution and ecology of both subspecies are discussed, as is their conservation status.
