The most recent studies <strong>of</strong> <strong>the</strong> <strong>bryophytes</strong> <strong>of</strong> <strong>Tamil</strong> <strong>Nadu</strong> are published in Daniels (1998, 2001,<br />
2004), Daniels & Daniel (2002–2008), Daniels and Kariyappa (2007), Kumar and Maniselvan<br />
(1994), Maniselvan and Kumar (1998, 2000a, b) and Srivastava and Verma (2005).<br />
Despite <strong>the</strong> relatively long history <strong>of</strong> bryological recording in <strong>Tamil</strong> <strong>Nadu</strong>, collecting has been<br />
sparse and sporadic, and much <strong>of</strong> <strong>the</strong> state remains bryologically unexplored or underexplored.<br />
Fur<strong>the</strong>r study is expected to yield many additions to <strong>the</strong> checklist.<br />
The checklist is not a taxonomic document, and no new taxonomy or nomenclature is published<br />
here: it is merely a compilation <strong>of</strong> published records (plus those in Daniels (2003), an unpublished<br />
<strong>the</strong>sis), and no claim is made as to <strong>the</strong> correctness <strong>of</strong> all identifications. However, <strong>the</strong> occurrence<br />
<strong>of</strong> some species in <strong>Tamil</strong> <strong>Nadu</strong> is considered uncertain or erroneous on taxonomic or geographical<br />
grounds, and <strong>the</strong>y are separately listed. Some o<strong>the</strong>r species that remain in <strong>the</strong> main list might be <strong>of</strong><br />
uncertain occurrence in <strong>Tamil</strong> <strong>Nadu</strong>, and require confirmation.<br />
The bryophyte flora<br />
<strong>Tamil</strong> <strong>Nadu</strong> supports approximately 29 % <strong>of</strong> <strong>the</strong> <strong>India</strong>n liverwort flora, 22 % <strong>of</strong> <strong>the</strong> hornwort flora<br />
and 30 % <strong>of</strong> <strong>the</strong> moss flora. <strong>India</strong>n endemic species are well represented in <strong>the</strong> state. Of <strong>the</strong><br />
approximately 152 liverwort taxa endemic to <strong>India</strong> (including all island groups and Sikkim), 30<br />
liverworts (19%) are known from <strong>Tamil</strong> <strong>Nadu</strong>, ten <strong>of</strong> which are apparently endemic to <strong>the</strong> state.<br />
Of <strong>the</strong> 19 <strong>India</strong>n endemic hornworts, two (10 %) are currently known from <strong>Tamil</strong> <strong>Nadu</strong>. About 65<br />
<strong>India</strong>n endemic mosses are known from <strong>Tamil</strong> <strong>Nadu</strong>, about 48 <strong>of</strong> <strong>the</strong>se apparently endemic to<br />
<strong>Tamil</strong> <strong>Nadu</strong>.<br />
SYNOPSIS OF FAMILIES AND GENERA<br />
Families are arranged alphabetically within each Division. The placement <strong>of</strong> genera in <strong>the</strong> families<br />
<strong>of</strong> <strong>the</strong> Marchantiophyta follows Crandall-Stotler, Stotler & Long (2008), for <strong>the</strong> Anthocerotophyta,<br />
Duff et al.(2007) and for <strong>the</strong> Bryophyta, G<strong>of</strong>finet et al. (2004).<br />
The checklist includes 712 taxa <strong>of</strong> <strong>bryophytes</strong>, comprising 211 taxa in 56 genera and 32 families<br />
<strong>of</strong> <strong>the</strong> Marchantiophyta (liverworts), 9 taxa in 4 genera and 2 families <strong>of</strong> <strong>the</strong> Anthocerotophyta<br />
(hornworts) and 493 taxa in 189 genera and 44 families <strong>of</strong> <strong>the</strong> Bryophyta (mosses). The number <strong>of</strong><br />
accepted taxa in each genus reported from <strong>Tamil</strong> <strong>Nadu</strong> is given in brackets following <strong>the</strong> genus<br />
name, and excludes <strong>the</strong> taxa that are listed under 'doubtful and erroneous records'.<br />
