Petrocodon multiflorus F. Wen & Y. S. Jiang sp. nov. (Gesneriaceae) is described and illustrated. It is most similar to P. dealbatus Hance, but can be distinguished by its leaf lamina texture, shape of leaf margins, and by the number of cymes borne by an individual plant and the number of flowers in each cyme.

Aspidistra punctatoides sp. nov. (Ruscaceae) from limestone areas in Guangxi,China

Aspidistra punctatoides Yan Liu & C. R. Lin (Ruscaceae) is described and illustrated as a new species from limestone areas in southwestern Guangxi, China, near the border with northern Vietnam. It resembles A. punctata Lindl. in leaf size, a campanulate perianth densely covered with purple spots, lobes adaxially with two fleshy keels, and the peltate stigma, but differs by the stigma being adaxially truncate and densely papillate, and by the margin being 3‐ or 4‐lobed with lobes emarginate at apex.

Salvia petrophila G. X. Hu, E. D. Liu & Yan Liu, a new species from the Chinese provinces of north Guangxi and south Guizhou, is described and illustrated. The new species is similar to S. miltiorrhiza, but can easily be distinguished by its shorter, unbranched stem, subsucculent simple leaf, longer pedicel and corolla tube, oblong‐entire middle lobe of lower corolla lip and larger oblate pollen. It is included in S. sect. Drymosphace on the basis of its falcate‐compressed upper corolla lip and connivent posterior connectives.

Impatiens pingxiangensis sp. nov. (Balsaminaceae) from the limestone areas in Guangxi,China

Impatiens pingxiangensis H. Y. Bi & S. X. Yu (Balsaminaceae), a new species from the limestone areas in Guangxi, China, is described and illustrated. The new species is similar to I. obesa in having succulent stems, subsessile peduncle, tufted pedicel and the lower petal in each pair of lateral united petals being connate, but differs from the latter by having perennial stems, leaf blades with 7–9 pairs of lateral veins, 1–2‐flowered racemes, ovate inner lateral sepals, and elliptic capsule. Moreover, the pollen and seed coat characters also support the recognition of the new species.     

Fomitiporia pentaphylacis and F. tenuitubus spp. nov. (Hymenochaetales, Basidiomycota) from Guangxi, southern China

Two specimens of Hymenochaetaceae were collected from Guangxi, southern China, during a recent field trip in August 2011. They are described and illustrated here as two new species, Fomitiporia pentaphylacis and F. tenuitubus, based on a combination of morphological and phylogenetic (ITS and nLSU sequences) data. The two species share subglobose to globose, hyaline and thick-walled basidiospores with strongly cyanophilous in cotton blue and dextrinoid reaction in Melzer??s reagent. These characters are typical for Fomitiporia, differing from other genera in Hymenochaetaceae. F. pentaphylacis resembles F. pusilla in field by its minute basidiocarps, but F. pusilla has distinctly multiple tube layers and smaller basidiospores. F. tenuitubus is similar to F. erecta in both macro- and micro-morphological features, except its larger basidiocarps, smaller pores, and slightly shorter basidiospores. In the phylogenetic perspective, the two species nested within the Fomitiporia clade, but were separated from other sampled species as well as from each other.

2008年9月,在广西壮族自治区罗城县天河镇附近一洞穴采集到一批条鳅亚科鱼类标本。经鉴定,为岭鳅属(Oreonectes)一新种。新种与岭鳅属的其他已知种类在以下组合特征上有区别:背鳍条3,7;臀鳍条2,5;胸鳍条1,11～12;腹鳍条1,7;尾鳍分枝鳍条为14～16。头平扁;眼正常;下唇表面具浅皱。腹鳍起点位于背鳍起点垂线下方之前,尾柄上、下缘无明显鳍褶;尾鳍后缘平截。体侧具不明显的细小鳞片,或鳞片隐于皮下。头部无侧线感觉系统管孔。成体粉红色,无色素,各鳍透明;浸泡标本体呈乳黄色,不透明,通体无色斑。     

Primulina tsoongii sp. nov. (Gesneriaceae) from a limestone area in north Guangxi,China

Primulina tsoongii sp. nov. (Gesneriaceae) is described and illustrated here. This new species resembles P. hochiensis and P. hochiensis var. rosulata, but is easily distinguished by its sparsely hirsute mature leaves, narrow bracts (only 0.4–0.5 in diameter) and undivided yellowish ligulate stigma with dense elongate papillae.     

Geranium kikianum sp. nov. (Geraniaceae) from the southern Peloponnese,Greece

Geranium kikianum Kit Tan & G. Vold sp. nov. (Geraniaceae) is illustrated and described as a new species endemic to Greece. It occurs beside streams and other wet places in open Pinus nigra forest at the foothills of Mt Taigetos in the southern Peloponnese. It is closely related to G. macrorrhizum, a species more widely distributed in southern and central Europe, ranging from the southern Alps to the Balkan Peninsula. It differs from the latter by its smaller and narrower deflexed petal limb, slender claw and occurrence in wet habitats. The genome sizes of G. kikianum and of Greek populations of G. macrorrhizum are presented here for the first time. The nuclear DNA content (2C values) of 2.84 pg for G. kikianum and 2.83 and 2.87 pg for two G. macrorrhizum populations from Greece probably corresponds to a 2n=92 cytotype while the smaller genome size of 1.45 pg in a population of G. macrorrhizum from Mt Smolikas, Greece may correspond to a 2n=46 cytotype.     

Ostericum atropurpureum sp. nov. (Apiaceae) from Zhejiang,China

Ostericum atropurpureum G. Y. Li, G. H. Xia & W. Y. Xie (Apiaceae, Apioideae) from Zhejiang, China, is described and illustrated. It is closely related to O. huadongense Z. H. Pan & X. H. Li and O. sieboldii (Miquel) Nakai, but differs in having leaves with 1.5–9.0 cm long petiole, linear bracteoles 6–12 mm long, 5–9 rays, 7–14‐flowered umbellules, dark purple petals, broadly winged dorsal and lateral fruit ribs, 1.0–1.5 mm broad, 3–6 vittae in each furrow and 4–8 on the commissure.     

Rubia austrozhejiangensis sp. nov. (Rubiaceae) from Zhejiang,China

Rubia austrozhejiangensis Z. P. Lei, Y. Y. Zhou & R. W. Wang, a new species of Rubiaceae from China, is described and illustrated. The new species is similar to R. ovatifolia Z.

Hara ex Lauener, but differs from the former in having stems and branches cylindrical, not quadrate‐angled, long‐ovate to ovate‐lanceolate leaf blades, many‐flowered inflorescence, and smaller mericarps, 3–4 mm in diameter. In R. ovatifolia, stems and branches are quadrate‐angled, leaf blades ovate, ovate‐cordate to rounded cordate, and the inflorescences are sparsely flowered. Compared to R. argyi, the new species has cylindrical, not quadrate‐angled stems and branches, leaf blades that are long‐ovate to ovate‐lanceolate, 3–5‐veined, and slightly reflexed corolla lobes. In R. argyi, stems and branches are quadrate‐angled or winged, the corolla lobes are spreading, and the mericarps are 5–7 mm in diameter.

Munronia yinggelingensis R. J. Zhang, Y. S. Ye & F. W. Xing, a new species of Meliaceae from Hainan, China, is described and illustrated. Notes are also presented on the phenology, ecology and conservation status of the new species. The new species was found growing in the valley rain forests of Yinggeling Nature Reserve at altitudes of 600 m a.s.l. in Gaofeng, Baisha County, Hainan Province, China. It is closely related to Munronia delavayi Franch., but differs in its entire or inconspicuously coarsely serrate margins of leaflets, longer inflorescence (8–30  cm), longer calyx lobes (5 mm), shorter coronal tube (1.2–1.5  cm), with white hairs on both sides, shorter coronal lobes (0.6–0.9  cm) and shorter stamen tube (1.8  cm).
