A new variety of Monochoria C. Presl from Thailand, M. vaginalis （N. L. Burman）Kunth var.angustifolia G. X. Wang, is described. This variety can be distinguished from the typical one, M. vaginalis var. vaginalis, by having mature leaves narrowly lanceolat     

Wood-inhabiting marine fungi from the coast of Shandong, China Ⅲ

Five species of higher marine fungi were observed on the incubated drift and intertidal woods collected from the coasts of Yellow Sea and Bohai Sea. Among them, Halosphaeriopsis was a genus newly recorded for China. Taxonomy and morphology of these species were discussed in this paper. The specimens were deposited in Mycology Herbarium at Qingdao Agricultural University （MHQAU）.

A new recorded genus, Cephalaria Schrad. ex Roem. et Schult. (Dipsacaceae), is reported here and C. gigantea (Ldb.) Bobr. is found for the first time inXinjiang, China.     

A new species of Anaphalis（Compositae）from Xizang，China

Anaphalis yangii Y. L. Chen&Y. L. Lin,a new species of Compositae from Gongbo’gyamda County,Xizang,is described and illustrated. The new species is quite similar to A. spodiophylla Ling & Y. L. Chen,but can be easily distinguished by its thicker,bro     

A new species of Fuziidae (Insecta, Blattida) from the Inner Mongolia, China

A new species attributed to the genus Parvifuzia Guo & Ren, 2011, Parvifuzia peregrinasp. n., is described from the Middle Jurassic Jiulongshan Formation of Daohugou Village, Inner Mongolia, China. This new species, with apex of wing almost reaching the end of the abdomen and forewing venation with 30-32 veins at margin, broadens the diversity of Parvifuzia. This new species, with strongly curved cerci, could tightly clasp female and complete copulation more efficiently, same as other members of the family Fuziidae.     

Wulfeniopsis Hong—A new genus of Scrophulariaceae from Himalaya

While we were investigating the world Veroniceae we found the genus Wulfenia Jacq. discontinuously distributing. W. carinthiaca and W. baldaccii are found in south-eastern Europe and W. orientalis in Turkey and Lebanon, whereas W. amherstiana is a native of W. Himalaya. Such a pattern of distribution, discontinuous between the Mediterranean and W. Himalaya, as far as we know, is hardly frequent. After comparing carefully the specimens from these two places and examining their pollen grains we got the impression that the difference between the plants occuring near the Mediterranean and those in Himalaya is so big that they should no longer be placed in the same genus. It would be necessary, therefore, to describe W. amherstiana as a new and separate genus (we name it Wulfeniopsis Hong). Its corolla is not 2-lipped, but with four lobes (not five) lanceolate, acuminate and erect (not spreading). The stigma is very small, not 2-lobed. Pollen grains are much smaller, with colpi more narrow and lacking of membranes, and their exines are smooth (not reticulate). It’s chromosome numberis 2n = 16 (not 18).     

Nebulosides A–B,novel triterpene saponins from under-ground parts of Gypsophila arrostii Guss. var. nebulosa

A bioassay-guided phytochemical analysis of the triterpene saponins from under ground parts of Gypsophila arrostii var. nebulosa allowed the isolation of two triterpene saponins; nebuloside A, B based on gypsogenin and quillaic acid aglycone. Two new oleanane type triterpenoid saponins (nebuloside A, B) and three known saponins (1–3) were isolated from the root bark of Gypsophila arrostii var. nebulosa. The structures of the two new compounds were elucidated as 3-O-β-d-galactopyranosyl-(1→2)-[β-d-xylopyranosyl-(1→3)]-β-d-glucuronopyranosyl quillaic acid 28-O-β-d-glucopyranosyl-(1→3)-[β-d-xylopyranosyl-(1→3)-β-d-xylopyranosyl-(1→4)]-α-l-rhamnopyranosyl-(1→2)-β-d-fucopyranosyl ester (nebuloside A) and 3-O-β-d-xylopyranosyl-(1→3)-[β-d-galactopyranosyl(1→3)-β-d-galactopyranosyl-(1→2)]-β-d-glucuronopyranosyl gypsogenin 28-O-β-d-glucopyranosyl-(1→3)-[β-d-xylopyranosyl-(1→3)-β-d-xylopyranosyl-(1→4)]-α-l-rhamnopyranosyl-(1→2)-β-d-fucopyranosyl ester (nebuloside B), on the basis of extensive spectral analysis and chemical evidence. Nebuloside A and B showed toxicity enhancing properties on saporin a type-I RIP without causing toxicity by themselves at 15 μg/mL.     

Elatides sandaolingensis n. sp. (Cupressaceae sensu lato) — A new fossil conifer with cones from the Middle Jurassic of Xinjiang,northwestern China

Here we describe a new conifer fossil, Elatides sandaolingensis Z.X. Wang and B.N. Sun n. sp., from the Middle Jurassic Xishanyao Formation in the Turpan-Hami Basin, Xinjiang Uygur Autonomous Region, northwestern China. The materials consist of compressions represented by well-preserved leafy shoots, pollen cones, and seed cone. Leaves are characterized by long triangular shapes, with straight apex and entire margins, and two stomatal bands on the abaxial surface. Pollen cones are terminally disposed on the ultimate leafy shoots, borne singly or in clusters. Pollen sacs are long-oval shaped, with three pollen sacs fused together. Pollen grains are spherical and have small germinal papilla and few wrinkles. The seed cone is oblong, with more than 35 helically arranged bract-scale complexes, which are characterized by long-oval shape and triangular apex. Compared with the extant nine genera of Taxodiaceous Cupressaceae in the morphology of seed cone and pollen cones, the present fossil consistently shares many characteristics with the extant genus Cunninghamia, but differs in other aspects. After being compared with the reported fossil records of the fossil plants, the current species is found to be different from any known species; thus, the present fossil is referred to as a new species of Elatides. From the similarity between the present fossil and Cunninghamia, it can be inferred that there may be a genetic relationship between these two genera. Additionally, the new species has thin cuticles and slightly sunken stomata, which can provide evidence indicating that the climate of the Turpan-Hami Basin in Middle Jurassic might have been warm and humid. By studying the geological history and geographical distribution of Elatides, it can be inferred that this genus may have originated in Switzerland, and it was migrated from Xinjiang to North and South China through the Ural Mountains.
