A New Freshwater Amoeba: Cochliopodium pentatrifurcatum n. sp. (Amoebozoa,Amorphea)

Cochliopodium pentatrifurcatum n. sp. (ATCC^© 30935^TM) is described based on light microscopic morphology, fine structure, and molecular genetic evidence. Cochliopodium pentatrifurcatum n. sp. (length ~ 25 μm) is characterized by surface microscales (0.3 μm tall) containing a circular porous base (~ 0.6 μm diam.) with a thin peripheral rim. Five radially arranged feet, emanating from the base, support a short central column terminating apically as a funnel‐shaped collar (~ 0.5 μm diam.) composed of five radial, trifurcate rays extending from the center toward a thin peripheral rim. The central spine is 0.5–0.6 μm long. The comparative morphologies and combined molecular genetic evidence, SSU‐rDNA and COI, indicate that the new species falls in a clade sufficiently different from other species to suggest that it is a valid new species.     

A New Freshwater Naked Lobose Amoeba Korotnevella venosa n. sp. (Amoebozoa,Discosea)

A new freshwater species of naked lobose amoebae Korotnevella venosa n. sp. isolated from freshwater pond in St. Petersburg, Russia was studied with light and transmission electron microscopy. Basket scales of this species have six vertical columns supporting perforated rim. The latter has tongue‐like broadening with membranous region. Vertical columns bifurcate at both ends so that neighboring columns are connected by their bifurcations forming combined structure. Basket scales of K. venosa are similar to those of Korotnevella hemistylolepis in having six full‐length vertical columns and perforated rim. At the same time, they are different in having tongue‐like broadening of perforated rim with membranous region and absence of six half‐length columns and an intermediate crosspiece. Phylogenetic trees based on 18S rDNA gene placed K. venosa either at the base of the whole Korotnevella clade, next to K. hemistylolepis, or as a sister to the clade comprising Korotnevella species with latticework basket in large scales.

A New Lignan Amide,Grossamide, from Bell Pepper (Capsicum annuum var. grossurri)

Two new phenolic amides, grossamide (7) and N-cis-feruloyl tyramine (2), have been isolated from the roots of bell pepper (Capsicum annuum var. grossum) together with p-aminobenzaldehyde (1), N-trans-feruloyl tyramine (3), N-trans-p-coumaroyl tyramine (4), N-trans-feruloyl octopamine (5), and N-trans-p-coumaroyl octopamine (6).

中国重楼属(延龄草科)一新变种——攀西直瓣重楼

描述了延龄草科一新变种--攀西直瓣重楼(Paris polyphylla Smith var.panxiensis J.L.Liu),并绘制了形态图.新变种以其叶片狭长、条形而与狭叶重楼(Paris polyphylla Smith var.stenophylla Franch.)和小重楼(Paris polyphylla Smith var.minor S.F.Wang)相近似,但又以花瓣线状圆柱形、直立、不弯曲、远短于萼片、向上逐渐增粗呈棒状、先端圆形或钝圆,花药药隔明显头状突起而有明显区别.
