Centaurea crocata Franco (1984: 474, 572) is the name currently used for a species of Asteraceae that is endemic to a small area in the southwest of Portugal, extending from Monchique (Algarve) to Cercal (Baixo Alentejo). The plant was first collected by Friedrich Welwitsch in 1847, in Monchique, during his residence (1847–1848) in the province of Algarve (Trimen 1873: 3). The following year he collected it again but further north, in Baixo Alentejo. Welwitsch regarded it as a new species and informally named it ‘Centaurea crocea’, as is apparent from the name written on his specimens of this species that are held in LISU (Garcia Jacas & Susanna 1991). However, he never published this name. Later authors working on the flora of Portugal, such as Sampaio (1909: 60, 1947: 597) and Coutinho (1913: 657, 1939: 776) misidentified Welwitsch’s and other collectors’ material as C. prolongoi Boissier ex Candolle (1838: 303, originally published as ‘prolongi’, corrected to ‘prolongoi’ as it commemorates the Spanish botanist Pablo Prolongo y Garcia). It was only much later that Franco (1984), in the second volume of his Flora of Portugal, concurred with Welwitsch’s view that the material belonged to a separate species and described it as C. crocata, using an epithet similar to that of Welwitsch’s unpublished name. Both epithets ‘crocata’ and ‘crocea’ originate from Latin and mean saffron-coloured. Saffron is a product of a species of the genus Crocus Linnaeus (1753: 36), a name with the same origin.

A New Species

Beaucarnea olsonii is described and illustrated from tropical deciduous forests of SW Puebla, Mexico. The new species can be distinguished from other Beaucarnea species by its massively swollen base that abruptly tapers into slender branches, by its conspicuously long stigma, and by its pedicel articulation that occurs at 2/3 of the length of the pedicel below the flower. With this new addition, the total number of endemic species of Beaucarnea for Mexico increases to 10, making this country the greatest center of diversification and endemism for the genus. We also provide a distribution map and a conservation status recommendation for the new species, as well as a key to the Beaucarnea species of southern central Mexico.

Representatives of some poorly known spider species collected in the rainforest litter of the Orchid Island (Taiwan) are illustrated and discussed here. A new species, Brignoliella tao sp. nov. (Fam. Tetrablemmidae), endemic to Orchid Island, is described based on both sexes. The previously unknown female of Theridiosoma triumphale Zhao & Li, 2012 (Fam. Theridiosomatidae), is described for the first time. Zoma taiwanica (Zhang, Zhu & Tso 2006) comb. nov., from the same family, is illustrated and its transfer from the genus Theridiosoma O. Pickard-Cambridge, 1879 to Zoma Saaristo, 1996 is proposed on the basis of morphological characters. Habitus and genitalia of the endemic species Gongylidioides angustus Tu & Li, 2006 (Fam. Linyphiidae) are also illustrated.

A New Species

The Atlantic Forest of Brazil includes one of the highest species diversity and endemism in the planet, representing a priority for biodiversity conservation. A new species of Anemopaegma from the Atlantic Forest of Brazil is here described, illustrated and compared to its closest relatives. Anemopaegma nebulosum Firetti-Leggieri & L.G. Lohmann has been traditionally treated as a morph of Anemopaegma prostratum; however, additional morphological and anatomical studies indicated that A. nebulosum differs significantly from A. prostratum and is best treated as a separate species. More specifically, A. nebulosum is characterized by elliptic and coriaceous leaflets (vs. ovate to orbicular and membranaceous in A. prostratum), smaller leaflet blades (3.6–5.5 x 2.0–3.0 cm vs. 6.7–13.0 x 4.2–8.4 cm in A. prostratum), orbicular prophylls of the axillary buds (vs. no prophylls in A. prostratum), solitary flowers (vs. multi-flowered axillary racemes in A. prostratum) and a gibbous corolla (vs. infundibuliform corollas in A. prostratum). In addition, A. nebulosum differs from A. prostratum anatomically in having thicker leaflet blades composed of two to four layers of palisade parenchyma (vs. one to three layers in A. prostratum), and seven to eight layers in the spongy parenchyma (vs. six to eight layers in A. prostratum). A key for the identification of all species of Anemopaegma from the Atlantic Forest of Brazil is presented.

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.

Aiphanes argos is a new species of palm segregated from Aiphanes parvifolia, which is now recognized to be a species complex. Aiphanes argos is one of the few rheophytic members of the palm family, and is endemic to a small area in the Samaná Norte River canyon in Antioquia, Colombia, where it is critically endangered because its populations are threatened by the damming of the river for a hydroelectric plant. The epiteth argos is the name of the conglomerate that intends to build the dam, and is given to the palm as a plea for the conservation of the Samaná Norte River canyon.

A new species, Dichoropetalum viarium (Apiaceae), is described from the Lorestan Province, Western Iran. The new species differs from D. paucijugum, D. aromaticum, and D. chryseum in the height, shape, diameter, and branching of the stem, shape of the terminal leaf lobes, shape of the bracteoles, shape and size of the mericarps, and shape of the stylopodium. In addition, D. viarium is recognized as a separate species by molecular analysis of nrITS.

Abstract—Artocarpus bergii, named for the late C. C. Berg, is from Halmahera in the Moluccas, and is a close ally of breadfruit (A. altilis). The species resembles the Micronesian A. mariannensis but with generally smaller parts. Because it is known from only a small area and the type locality is a potential mining site, A. bergii is likely of conservation concern, particularly given its status as a crop wild relative.

Pycreus rubidomontanus is described as a new species. It is relatively widespread in tropical West Africa where it had been confused up to present with P. atrorubidus, a very rare endemic species from Zambia in south-central Africa that probably is known only from the type gathering. Differences between these and other similar species are discussed and the new species is copiously illustrated.

Iucn Criteria

We describe here Begonia medeiroii, a narrow endemic species from the Atlantic Rainforest. The conservation status of this species was assessed as critically endangered according to IUCN criteria. This species resembles to B. catharinensis and B. hirtella in some characteristics, differing among other features due the presence of adventitious vegetative buds on the adaxial surface of the leaves.
