The paper reported the study of the types and flora of liverworts in the daweishan nature reserve of yunnan province by field surveying and data refereeing 摘要通过野外调查和文献考证，报道了云南大围山自然保护区叶附生苔类植物的类型及区系组成特点。
In bryophytes ( mosses , liverworts and horworts ) the haploid gametophyte is the dominant phase of the life cycle and the sporophyte is represented only by the capsule , seta , and foot 在苔藓类植物中（苔藓，地钱，金鱼藻）单倍的配子体占生活史的主要部分，孢子体包括孢蒴、蒴柄和基足。
Sporogonium the sporophyte generation in mosses and liverworts . it develops from the zygote and comprises the foot , seta , and capsule . the sporogonium is parasitic on the gametophyte generation 孢子体：为苔藓和地钱的孢子体世代具有。由受精卵发育而来，包括基足、柄和孢蒴。孢子体是寄生在配子体上的。
Hepatophyta ( marchantiopsida ; liverworts ) a phylum containing leafy and prostrate thallose forms , commonly known as liverworts , thallose liverworts are prostrate and dichotomously branched with thalli several cells thick 苔类植物门（地钱纲，苔类） ：是一门包括多叶的或匍匐叶状体类型的植物，如通常所说的苔类。
The liverworts divides into three types in the nature reserve , obligate , commonly facultative and occasionally facultative types and the commonly facuhative type is dominant totaling 26 species and accounting for 60 . 4 % of all the species in the reserve 保护区内叶附生苔类植物可以分成3种类型：专性、兼性常见和兼性偶见，其中兼性常见类型种类占有绝对优势，共有26种，占其总种数的60 . 47 % 。
Like thallose liverworts , the hornworts have an alternation of generations in which the gametophyte is a dorsiventral flattened green phallus and the saprophyte is an upright structure that has a foot embedded in the gametophytes , from which it draws nutrition 与叶状体植物地钱一样，角苔具有明显的世代交替， ，配子体在世代交替中占优势，孢子体占劣势且利用其基足插入配子体的组织中吸取养料，以供孢子体生长。
