Zingiber hainanense (Zingiberaceae), a new species from Hainan, China, is described and illustrated. It is compared to two most similar members from Z. sect. Cryptanthium, Z. guangxiense from Guangxi, China and Z. kawagoii, an endemic species from Taiwan, China. Zingiber hainanense differs from Z. guangxiense mainly by labellum and staminodes being purple red (vs. yellowish white throughout in Z. guangxiense), and differs from Z. kawagoii by labellum and lateral staminodes being linear or narrowly ovate (vs. obovate-oblong in Z. kawagoii). The pollen morphology and chromosome number count as well as a color plate of the new species are also presented in this study.

A New Species

A new species, Loncomelos koprulense (Asparagaceae), is described and illustrated from southern Turkey. It is a very rare endemic species growing on small semi-rocky escarpments within the Köprülü Kanyon in the province of Antalya. Morphologically for its hairy leaves, L. koprulense shows some relationships with L. malatyanum and L. tardum, species localized in Anatolia too. The chromosome number of the new species is 2n = 2x = 22. The identification key to L. koprulense and its allied species is provided, as well as their geographical distribution map.

Scrophularia dianatnejadii Ranjbar & Rahchamani, a new species from Tehran Province in northern Iran, is described and illustrated. It is closely related to S. amplexicaulis Benth. and shares with it some diagnostic morphological characters such as habit, plant indument, phyllotaxy, and corolla shape and color. Both species are placed in Scrophularia L. sect. Mimulopsis Boiss. Macro- and micromorphological characters of the two are examined and compared. Pollen morphology of these species is investigated using SEM. Detailed descriptions, illustrations, distribution maps, and conservation status of both species are provided.

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.

Aspidistra revoluta (Asparagaceae) is described and illustrated as a new species from limestone areas in southern Chongqing Municipality, China. The new species can be distinguished from the other Aspidistra species by its unique umbrella-like pistil with large revolute stigma lobes that bent downwards and touch the base of the perigone. A detailed morphological comparison among A. revoluta, A. nanchuanensis and A. carnosa is provided. The pollen grains of A. revoluta are subspherical and inaperturate, with verrucous exine. The chromosome number is 2n = 38, and the karyotype is formulated as 2n = 22m + 6sm + 10st. The average length of chromosome complement is 4.50 μm, and the karyotype asymmetry indexes A1 and A2 are respectively 0.37±0.03 and 0.49±0.01.

Epimedium muhuangense (Berberidaceae), a new species from Guizhou, China, is described and illustrated. This species is most closely similar to E. elachyphyllum in having simple leaves, petals shorter than inner sepals, flowers less than 10 mm in diameter and in having the same pollen morphology as well, but differs by having stout, short rhizomes, two opposite, glabrous leaves on flowering stems, and paniculate inflorescences. The chromosomes of E. muhuangense is counted as 2n = 12 and the karyotype is formulated as s 2n = 2x = 6m (2sat) + 6sm. Line illustrations, color photographs, and micrographs of chromosomes and of pollen grains of E. muhuangense are provided.

A New Species

In May 2020, a new taxon of Euphorbia, Euphorbiaceae was collected from a dry hillside of Dongsheng District, Ordos City, Inner Mongolia. The morphological characteristics of the specimens analyzed differ from those of the known Euphorbia species from this region; therefore, we suspected this may be a new species, and we set to analyze the ITS2 sequences of some Euphorbia species. The results show that the new taxon belongs to the sect. Esula of Euphorbia subg. Esula. It is similar to Euphorbia esula (description from Flora of China) but does not belong to the same species. Concomitantly, plant morphological data and pollen morphology results show significant differences between the new taxon, E. esula and E. caesia, a finding that supports the delimitation of this new taxon, which is named Euphorbia mongoliensis in accordance with its geographical distribution.

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.
