Pellionioides,being 15-90 in number per cyme,papery in texture,green in colour,narrowly ovate or triangular,or linear in outline,0.5-4 mm in length,flat,without any projection,are very similar to those of staminate cymes in the two genera of trib. Elatostemeae,Pilea and Pellionia,and their morphological features just mentioned above may be considered the primitive characters of the bracts in the genus Elatostema. On the basis of them the following evolutionary trends in involucral bracts are observed:(1)more of less equal in size and similar in shape,uniseriately verticillate on receptacle margin→arranged in two series,with two outer bracts opposite and larger,and the inner bracts smaller and more or less different in shape from the outer two;(2)narrowly ovate or triangular,or linear→broadly ovate or triangular,or depressed-semiorbicular→owing to reduction in size resulted from further strong decrease of length and increase of width disappearring at last;(3)flat→cucullate at apex→navicular→navicular,with a terminal cylindrical projection;(4)lacking any projection↗abaxially carinate,or longitudinally 1-6-costate or winged ↘shortly to longly cornicullate at apex→corniculate abaxially below apex;(5)free→connate at base→owing to strong decrease of length and strong increase of width,the involucral bracts are connate into a transversely linear lamella around the receptacle margin;(6)increasing to fifty to one hundred and eighty from seven to forty-five in number per inflorescence on the one hand,and decreasing to less than five on the other.

On the basis of the evolutionary trends of the leaves,leaf nervation,pistillate inflorescences,pistillate tepals and achenes a putative phylogenetic tree showing the relationships among the infrageneric groups of the genus Pellionia is provided.(3)The infrageneric taxa of Pellionia in China are revised.

In the latter,the leaves are larger,up to 6 cm long and 6.2 cm broad,and the segments are all conspicuously dentate at margin,brown-pubescent abaxially,and the lateral segments unequally 2-lobed. According to the author's speculation that these two related taxa might be a pair of sister groups derived from the same species,V. bryoniifolia,in this paper,the latter variety is elevated to specific rank,and for this species a new name must be given owing to the presence of a species name,V. ternata Baker,which was published in 1871 from Brazil.]]> 2016/8/24 16:49:11 WANG Wen-Cai 6true Meconopsis(Papaveraceae), are described as new from western area of Sichuan Province, China.
