简介:
《The Early Devonian Posongchong Flora of Yunnan--A Contribution to an Understanding of the Evolution and Early Diversification of Vascular Plants》is a monographic summary ofcurrent knowledge ofthe Early Devonian Posongchong flora from Yunnan，southwestern China ， whichis emerging as one ofthemostimportant sources ofinformation on early vascular plants The many species recovered from the Posongchong Formation，including some endemic plants with tmusual combinations offertile and vegetative organs，are described in detail， and allupdated classification systemispresented Thepaleoenvironments in which plants lived have been reconstructed by a study of sedimentological facies and taphonomy。The Posongchong flora is compared to other coeval floras from throughout the world。The phylogenetic relationships of the Posongchong plants have been assessed by cladistic analyses，including the parsimony method and Bayesian inference The evolution and early diversification ofearly vascular plants have then been discussed ln terms ofanalyses ofmorphological and anatomieal characters as well as diversity dynamics The evidence from the Posongchong flora supports the hypothesis that the explosion ofmajor lineages ofvascular plants occurred during the Early Devonian（Pragian）age As suggested by Charles B Beck in the foreword，“it is clear that this flora provides an unusuallyimportant contributionto our knowledge of plantlifein the Devonian，and awealth ofinformationforbiologists and geologists who seek to understand the myriad pathways ofplant evolution”。
