Parahyparrhenia khannae, a new species of Andropogoneae (Poaceae: Andropogoneae) from the grassland of Ratlam and Jhabua districts of Madhya Pradesh, India is described and illustrated. The new species is similar to the Indian endemic species P. bellariensis in having dorsal groove in lower glume of sessile spikelet, but differs in having shorter plant height, lacerate membranous ligule, shorter leaf blade and raceme length, fewer homogamous spikelets, shorter sessile spikelet and anther length.

A new species of the state of Chiapas, Ilex montebellensis, is herein described and illustrated. The specimens were previously determined as I. mitis, an endemic species of Africa. This new species is morphologically akin to I. tectonica but differs for presenting larger leaves, 9.0‒22.0 × 4.0‒9 cm, petioles 1.5‒4.0 cm, masculine inflorescences in fasciculated dichasia, fruit with hard mesocarp and dorsally smooth pirenes. The checklist of species for Mexico and Mesoamerica is analysed. An identification key with Mesoamerican species that share the entire character of the leaf blade with the new species, is provided.

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.

Ischaemum mistryi, a new species from the Sub-Tropical evergreen forest of Tilari Ghat, Maharashtra, India, is described and illustrated. This grass is unique with its leaves drooping, mostly congregated near the base, basal sheath villous, culms compressed at the base, lower glume of the sessile spikelet linear-lanceolate to oblongish tapering and slightly curled upwards, without a sub-apical ridge, nodules absent (if present 2–4 obscure) on its keels, and upper lemma of sessile spikelet bi-partite. Morphologically it is somewhat similar to I. mangaluricum, I. travancorense and I. barbatum. We provided a table of its detailed comparison with close species as mentioned above. According to IUCN Red List Categories and Criteria, we have assessed this new species as Critically Endangered (CR). The photo plates and illustration of the grass are given to facilitate its proper identification. A short discussion is also provided at the end.

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.

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.

Paradrymonia vivianensis R. Rojas & M. M. Mora (Gesneriaceae), a new species discovered in the Chambirillo sector of Cordillera Azul National Park, Peru, is described and illustrated. Paradrymonia vivianensis differs from other members of the genus mainly by its leaves with the leaf blade elliptical to obovate, purplish green above and uniformly purple below, the base subcordate and slightly asymmetric, the margin crenate, and the midvein and secondary veins contrasting yellowish green above.
