On the Classification of Ixeris Group (Compositae) from China

Ixeris Cass., strinctly speaking, is confined to plants which have achenes with sharply winged ribs. Ixeridium (A. Gray ) Tzvel. contains plants which have persistent radical leaves at anthesis and achenes with obtuse ribs and a fine rostrum at its apex. Paraixeris Nakai is restricted to plants which are of the same achenes as in the genus Ixeridium (A. Gray) Tzvel., but rostra of achenes are robust and radical leaves deciduous in flowering in the former. The Chorisis DC., a monotypic genus, is characterized by ternate palatisect leaves. In the light of the above mentioned understanding of these genera, the author thinks that the division of Chinese Ixeris group, a comparatively complex one, into four genera would be more reasonable than merging them into one genus, namely, Ixeris Cass. Based on the examination of specimens in the Herbarium of the Institute of Botany, Academia Sinica (PE), the author found that there are four species in the genus Ixeris Cass., including one new combination in China. They are I. polycephala Cass., I. dissecta (Makino) Shih, I. japonica (Burm. f. ) Nakai and I. stolonifera A. Gray. The genus Ixeridium (A. Gray ) Tzvel. has 13 species, including five new combinations and three new species in China, namely, I. sagittaroides (C. B. Clarke) Shih, I. gramineum (Ledb.) Tzvel., I. yunnarense Shih,I. graminifolium(Ledb.)Tzvel.,I, biparum Shih,I.aculeolatum Shih,I. chinense( Thunb. ) Tzvel., I. strigosum( Fisch. ) Tzvel., I. elegans( Franeh. ) Shih, I. sonchifolium (Maxim.)Shih,I. laevigatum (BI.)Shih,I. dentatum(Thunb. )Nakai and I. gracile(DC.)Shih, in China. There are six species in the genus Paraixeris Nakai, including One new combination, namely, P. denticulata(Houtt.) Nakai, P. humifusa(Dunn) Shih, P. cheldonifolia( Makino) Nakai, P. saxatilis( Baran. ) Tzvel., P.pinnatipartita (Makino)Tzvel. and P.serotina(Maxim.)Tzvel.in China.

中国桂樱属植物的分类研究

桂樱属(Laurocerasus Tourn.ex Duh.)是蔷薇科李亚科的一个属。它是De Tournefort(Institutiones rei Herbariae 627.t.403.1700)以Prunus laurocerasus L.和P.lusitanica L.两种奠定基础,而至1755年由Duhmal代为正式发表而建立。自该属建立以后的二百多年来,各国植物学家对其分类位置各持不同观点。     

A New Genus (Protosciadopityoxylon gen. nov.) of Early Cretaceous Fossil Wood from Liaoning,China

A new genus ( Protosciadopityoxylon gen nov. ) of Early Cretaceous fossil wood reported in the present paper was discovered from Liaoning Province, China, and is named as a new species:Protosciadopityoxylon liaoningense gen. et sp. nov. It is described here and this generic name, adopted by the authors, is employed for fossil wood that is believed to be nearly related to the recent genus Sciadopitys and the fossil genus Sciadopityoxylon. The new genus bears some similarities to Protophyllocladoxylon,Protocircoporoxylon and Xenoxylon in different geological ages, but it differs from them in the types of cross-field pitting.     

Additional Notes on the Begonia Sect. Petermannia (Begoniaceae) from China

Begonia pellionioides YM. Shui & WH. Chen, a new species of the genus Begonia L. (sect. Petermannia (Klotzsch) A. DC., Begoniaceae), is described and illustrated. The new species is endemic to limestone areas in Southeastern Yunnan Province, China, and is most similar to Begonia hainanensis Chun & F. Chun but distinguished by its more elongated leaves with cuneate base and acuminate to caudate apex, tepals adaxially with spiny hairs and sharply triangular capsule wings with truncate superior margin. Besides, the unknown flower morphology of previously published Begonia sublongipes YM. Shui in Begonia sect. Petermannia is described.
