Scapania paraphyllia T. Cao,C. Gao,J. Sun & B. R. Zuo,a new species of Hepaticae (Scapaniaceae) from Zhejiang,China

A new liverwort species, Scapania paraphyllia T. Cao, C. Gao, J. Sun & B. R. Zuo, is described and illustrated from Zhejiang, China. The new species is closely related to S. bolanderi Aust. in having similar toothed leaves and pseudoparaphyllia. The former, however, differs from the later by having: (1) smaller plants; (2) pseudoparaphyllia numerous, not only growing on leaf axils but also on stems; (3) leaves divided into 1/4–1/3 of length and dorsal lobes as 1/3–1/2 size of ventral lobes; (4) cuticle of leaves rough, with large papillae up to 6–8 µm in diameter.

六种鲟鱼消化酶活性的比较研究

测定了两个生长阶段 6种鲟鱼幼鱼胃、肠道和肝脏中蛋白酶、脂肪酶、淀粉酶活性。幼鲟消化酶活性在两个生长阶段变化不明显。 6种鲟鱼不同消化器官蛋白酶活性以肠道为最高 ,肝脏为最低 ,肝脏中的蛋白酶活性明显低于胃、肠道 (P <0 0 1)。不同消化器官脂肪酶活性 ,以肠道为最高 ,且肠道脂肪酶活性显著高于胃、肝脏 (P <0 0 1) ,胃中的脂肪酶活性与肝脏中的脂肪酶活性差异不明显 (P >0 0 5 )。不同消化器官淀粉酶活性 ,以肠道为最高 ,且明显高于胃、肝脏 (P <0 0 1)。幼鲟在第一阶段 ,肝脏中没有淀粉酶活性 ,其活性出现在第二阶段 ,且在此生长阶段 ,肝脏中的淀粉酶活性达到胃中的水平 (P >0 0 5 )。对 6种鲟鱼而言 ,除个别存在较大差异外 ,3种消化酶活性大体上都没有明显差异     

云南节肢蕨属(水龙骨科)一新种——贯众叶节肢蕨

报道了产于中国云南高黎贡山的水龙骨科Polypodiaceae节肢蕨属Arthromeris一新种——贯众叶节肢蕨A.cyrtomioides S.G Lu＆C.D.Xu。该新种的植标大小与节肢蕨A .lehmanni（Mett.）Ching相似。但叶片的背面密被绒毛,表面被短柔毛,侧生羽片9-16对。该新种在毛被方面与厚毛羽毛节肢蕨A.tomentosa W.M.Chu相似,但羽片边缘无软骨质的膜质边,侧生羽片多达9-16对。     

中国重庆毛茛科银莲花属一新种——涪陵银莲花

描述了中国重庆市涪陵区的毛莨科Ranunculaceae银莲花属Anemone一新种——涪陵银莲花A．fulingensisW.T．Wang＆Z．Y.Liu,并绘出墨线图。根据此新种的总苞苞片无柄,花具4-5枚萼片,花丝丝形,花粉具散沟等特征,可以确定此种应是属于银莲花属鹅掌草组Anemone sect．Stolonifera的一个成员;在该组中,此种以其独特的由2-10个块茎组成的念珠状根状茎而与该组的其他种相区别。鉴于在银莲花属中块茎出现于不同的演化路线中,以及这些块茎的出现系次生现象,可见此新种应是鹅掌草组的进化种。     

Wentsaiboea D. Fang & D. H. Qin,a new genus of the Gesneriaceae from Guangxi,China

Wentsaiboea renifolia D. Fang & D. H. Qin, a new genus and species of Gesneriaceae from Guangxi, China, is described and illustrated. This genus is similar to Dolicholoma D. Fang & W. T. Wang in the shape of stigma, but differs by having leaves reniform, palmately nerved and base cordate, corolla obliquely campanulate, corolla lobes rounded, and both stamens and staminodes adnate to corolla tube near base. It is also similar to Chiritopsis W. T. Wang in the habit, but differs by having leaves palmately nerved, corolla tube campanulate and abaxially swollen, and stigma hippocrepiform.
