引言三个谱系的bratelites，苔藓，地钱，和金鱼藻，组成成功的早期胚胎植物群。苔藓估计包括约12700种（克罗斯比等. 2000），苔类约6000-8000现存种（Crandall-Stotler & Stotler 2000，第1章，本卷），角苔类约100-150种（第3章，本卷）。苔藓在物种丰富度方面与念珠藻相当，估计包括约11500种（Pryer et al . 2004年）。因此，在现存的陆生植物中，目前只有被子植物的种类比被子植物的种类多。人们常说，热带地区的生物种类最多，符合许多生物群的一般模式，赤道地区的物种丰富度不断增加（Rosenzweig 1995）。然而，在苔藓的纬度多样性模式的定量分析未能检测到任何这样的纬度梯度，除了在美洲可能是一个弱的（肖等。2005年a）。看来，苔类植物的多样性在南半球中高纬度地区最高，尽管有一个科，勒琼科，在新大陆和旧大陆的潮湿热带森林中高度多样（Gradstein 1979）。苔藓、地钱和角苔的化石记录太不完整，无法评估这些类群在过去的地质时期是否有更多或更少的多样性（米勒1984，奥斯坦多普1987）。
Introduction The three lineages of bryophytes, mosses, liverworts, and hornworts, compose successful groups of early embryophytes. The mosses are estimated to include some 12 700 species (Crosby et al . 2000), the liverworts approximately 6000–8000 extant species (Crandall-Stotler & Stotler 2000, Chapter 1, this volume), and the hornworts about 100–150 species (Chapter 3, this volume). Mosses are comparable in species richness to the monilophytes, which are estimated to include about 11 500 species (Pryer et al . 2004). Among the extant land plants, therefore, only the angiosperms are currently more species-rich than are the bryophytes. It is often stated that bryophytes are most diverse in the tropics and fit the general pattern found in many groups of organisms, with increasing species richness toward the equator (Rosenzweig 1995). However, a quantitative analysis of latitudinal diversity patterns in the mosses failed to detect any such latitudinal gradient, except perhaps a weak one in the Americas (Shaw et al . 2005a). It appears that liverwort diversity is highest at moderate to high latitudes of the Southern Hemisphere, although one family, the Lejeuneaceae, is hyperdiverse in wet tropical forests of both the New and Old Worlds (Gradstein 1979). The fossil record for mosses, liverworts, and hornworts is too incomplete to assess whether these groups were more or less diverse in the geological past (Miller 1984, Oostendorp 1987).
