| Abstract: | In the present study, a taxonomic study are made of four new species of Chinese Sargassum belonging to the Species Group Swartzia of Subsection Glomeraltae,namely:Sargassum primitivum sp.nov.S. hainanense sp. nov., S. wenchangense sp,nov.and S. pusillum sp. nov.The type specimens are all deposited in the Herba-rium of the Institute of Oceanology, Academia Sinica at Qingdao China.Sargassum primitivum sp. nov. is mainly characterized by its receptacles cylind-rical with a few spinules or teeth limited to the apices. The new species is regar-ded as a primitive member of the Swartzia group.It is related to S.twartzii onthe one hand and to S. pirgatum of Fruticuliferae on the other, differing from theformer in its cylindrical receptacles and leaves with some sharp teeth and from thelatter in its tootbed reGeptacles and broader toothed leaves.Sargastum hainanense sp. nov. is closely related to S. dumosum, differing in theelongated linear leaves, and the vesicles with leaf-like stalk without teeth at themargin.Sargassum wenchangense sp. nov. is cartilaginous to very firm (unusual for Sa-rgassum), and short. It is related to S. Hainanense differing in its very short upperleaves, half of the upper leaves of S. hainanese, vesicular pedicels cylindrical andthe receptacles dilated in the upper parts, fan-like.Sargassum pusillum sp.nov. is related to S. swartzii differing in the frond verysmall, to about 11cm high, leaves on the secondary branches very asymmetrical,oblanceolate, broad linear or linear, with irregular serrate margins, pedicels flate,with a few serrate margins, receptacles usually dilate above and conspicuous spinu-les at the apices and margins.These characteristics make it easy to differentiatefrom other closely related species such as S. swartzii. |
