| Abstract: | The paper dealt with the fossil plants collected from Majian Formation in Majian, Lanxian county, western Zhejiang Province. The flora comprises about 54 species belonging to 28 genus. Two species of them are new. They are as fol-lows: Bryophyta: Thallites sp. ,Equisetales: Neocalamites carrerei ( Zeiller ) Halle, N. cf. carcinoides Harris, N. sp. , Equisetites sp. , Radicites sp. , Ferns. Todites denticulata ( Brongn. ) Krasser, T. princeps ( Presl ) Gothan, T. uiillia-msoni (Brongn. ) Seward, T. cf. thomasi Harris, Coniopteris hymenophylloides Brongniart, C. sp. Clathropteris meniscioides Brongniart, C. platyphylla(Goe-ppert) , Cladophlebis raciborski Zeiller, C. haiburenses ( L. et H. ) Brongiart, C. sp. 1, C. sp. 2, Sphenopteris sp. Pteridospermopsida: Ctenozamites stoma-tigerus Huang et Lu. Cycadophytes: Pterophyllum sp. ,Otozamites hsiangchiensis Sze, O. mixomorphus Ye, O. cf. graphicus ( Leckenby ) Phillips, O. lanxiensis Huang et Qi(sp. nov. ) , O. sp. 1, O. sp. 2, O. sp. 3, Ptilophyllum conti-guum Sze, P. pecten (Phillips ) Morris, P. hsingshanense Wu, Zamites sp. , Nilssonia undulata Harris, C. pterophylloides Nathorst, C. cf. taenioperioides Halle, Anomozamites cf. major(Brongn),A. sp. , Taeniopteris richtofeni(Shenk) Sze, T. sp., Cycadolepis corrugata Zeiller. Ginkgophytes: Ginkgoites sp. , Baiera guilhaumati Zeiller, B. cf. furcata ( L. et H. ) Braun, Sphenobaiera cf. huangi (Sze) Hsu, S. sp. Phoenicopsis sp. Coniferae: Elatides majianensis Huang et Qi(sp. nov. ) , Pityophyllum longifolium ( Nath. )Moeller, Podoza-mites shenki Heer, P. lanceolatus ( Lindley et Hutton ) Braun, P. sp., Sweden-bargia sp. , Conites sp., Carpolithus sp.. The flora is closely related with the Hsianchi flora of western Hubei, the Wuchang flora of southeast Hubei and Anhui. This flora can also be compared with the Yorkshire Jurassic flora. So the Majian flora should belong to the Early-Middle Jurassic in age. |
