海韭菜的花器官发生

运用扫描电镜（SEM）观察了海韭菜（Triglochin maritimum）的花器官发生发育过程。结果表明：海韭菜花发育是典型的单子叶植物发生模式,即两轮花被片、两轮雄蕊和两轮心皮以三基数轮状交替发生,花器官是以向心向顶的方式发生的,未发现“花被片—雄蕊复合原基”。 发育后期雄蕊和与之对生的花被片之间的共同基部可能是相继向上居间生长的结果。花被片轮和雄蕊轮二者之间在发育位置、时间和速率上存在差异,内轮花被片原基和外轮雄蕊原基的不同发育时间和发育速度使得在成熟花中内轮花被片位于外轮雄蕊的内方。观察结果不支持水麦冬属植物的花是退化（或压缩）的花序侧分枝等假花的观点。     

Effects of Salinity and Temperature on Seed Germination in a Japanese Endangered Halophyte Triglochin maritimum (Juncaginaceae)

Triglochin maritimum (Juncaginaceae). Germination tests were carried out at three salinity levels (0,200,400 mM NaCl in which seeds were exposed to increasing- or decreasing temperatures. Effects of moist-chilling pretreatment (stratification) in 0,200 and 400 mM NaCl on seed germination at 0,200 and 400 mM NaCl, respectively, were also examined. Under the highest salinity condition (400 mM NaCl), no germination was observed. The seeds germinated very well (88%) in fresh-water after 5-month moist-chilling pretreatment. Longer moist-chilling pretreatment resulted in higher germination percentages. Moist chilling pretreatment in 0,200 and 400 mM NaCl for 5 month enhanced germination percentages to 10% (in 400 mM NaCl) –88% (in 0 mM NaCl).

Notes on the Genus Lonicera Linn. of China

This paper, which consists of a part of pertinent data obtained through a critical revision of the genus Lonicera of China. discusses 28 noteworthy species and infraspecific taxa. Among them, 3 subspecies and 1 variety are new grades and combinations. Be-sides, 31 species, 11 varieties and 6 forms have been reduced to synonyms.     

Notes on the Genus Elaeocarpus Linn. from China

The Chinese Elaeocarpus Linn. is revised. Here reported are those taxa with different treatment in “Fl. Reip. Pop. Sin. “, Tomus 49 (1), including one new species and one new variety: Elaeocarpus limitaneioides Y. Tang and E. glabripetalus var. grandifructus Y. Tang, Four species and two varieties are reduced: E. boreali-yunnanensis H. T. Chang is reduced to E. lacunosus Wall. ex Kurz; E. floribundioides H. T. Chang to E. austro-yunnanensis Hu; E. fengjieensis P. C. Tuan to E. duclouxii Gagnep .; E. kwangsiensis H .T. Chang to E. glabripetalus var. alatus(Knuth) H. T. Chang; E. glabripetalus var. teres H. T. Chang to E. glabripetalus var. glabripetalus ; E. prunifolioides var. rectinervis H. T. Chang to E. prunifolioides Hu. It is found that three species, E. rugosus Roxb., E. sikkimensis Mast. and E. decandrus Merr., were wrongly determined as E. apiculatus Mast., E. fleuryi Gagnep. and E. chinensis Hook. f., respectively. In the paper also reported are some provincial new records. The infrageneric systems are discussed briefly and the Masters’ system isfollowed with some modifications.
