Hofmeister aso showed that the gametophytes and sporophytes of seed - bearing plants were homologous with those of ferns and mosses and that the gymnosperms formed a plant group between the latter and the angiosperms 他认为种子植物的孢子体和配子体与蕨类以及苔藓类是同源的，还指出裸子植物形成了一个单独的组群，它是位于蕨类植物与被子植物之间的一个植物类群。
There were 161 fanilies , 639 genera and 1450 species in jigong mountain natural conservation , the composition of its flora was abundant and complex , the flora was obviously temperate , and with especially transitional character from north to south 摘要鸡公山自然保护区共有种子植物161科639属1450种，其植物区系组成丰富、成分复杂，植物区系成分以温带类型为主并具有明显的南北过渡性质。
Among them , the cosmopolitans are 30 genera , 28 . 04 % of the entire angiosperm flora of the wetland , and it is consistent with the intrazonality of the wetland ecosystem ; the temperate elements , 44 genera , 41 . 12 % of the angiosperm flora , is the dominant one 但湿地植被也要受所在地气候带的制约，在植物区系上有所反映，南大港湿地植物区系中温带成分45属，占湿地种子植物总属数的41 . 67 ，远高于其它区系成分。
There were 71 species in the community 2 ( castanopsis fargesii - itea chlnensis - maesa japonica community ) , and castanopsis fargesii and itea chinensis were respectively the absolute dominant species of tree layer and succession layer , maesa japonica was the dominant species of regeneration layer 群落次生天然演替过程是以地带性植被壳斗科、茶科、冬青科等物种为主。总体上黄茵岭生态保护小区群落种子植物属的分布类型是以热带分布成分占绝对优势，种子植物以热带起源为主。
The 486 genera are devided into 13 types and 14 subtypes of geographical elements . analysis of the floristic composition and the geographical elements shows that the flora has a complex composition dominated by tropical elements . floristic analyses indicate that influences of the tropical flora and of the temperate flora are quite strong upon the gmnr flora , and the former is some stronger 从属的分布型的分析可知，该地区具有中国15个种子植物属分布区类型中的14个分布类型，表明该区系成分复杂，区系成分以热带?亚热带成分占优势，热带和温带成分均有影响，而以前者较为强烈。
In gmnr , so far a total of 1030 vascular species in 536 genera of 169 families have been listed , 141families , 486 genera , 949 species ( including intermination taxa , similarity hereinafter ) of the spermatophyta , including 4 families , 4 genera , and 7 species of the gymnospermae , and 137 families , 482 genera , 942 species of the angiospermae - - - - - - the dicotyledonae 117 families , 374 genera , 755species , and the monocotyledonae 20 families , 108 genera , 187 species 本文是对广东省古兜山自然保护区种子植物区系的组成与基本特点的研究，现知古兜山共有野生维管植物169科536属1030种(蕨类植物28科50属81种，裸子植物4科4属7种，双子叶植物117科374属755种，单子叶植物20科108属187种) ，具有部分古老孓遗种，以木本植物为主，其次为草本，藤本不多。
