IntroductIon
The Nilgiri Hills of Tamil Nadu are a part of the
Nilgiri Biosphere Reserve (NBR), recognized
under the Man and Biosphere (MAB) Program
of UNESCO. These hills (junction of Eastern
Ghats and Western Ghats) are formed by northsouth hill ranges rising from the coastal plains of
peninsular India, with a few isolated peaks such
as Dodabetta Peak (2667 m) and Mukuruti Peak
(2554 m). The Nilgiris lie between 10°01′ to 11°47′
latitude north and 76°12′ to 77°15′ longitude east,
covering ca 2549 km2. The area receives the southeast and northwest monsoons, making for very rich
bryolora, especially that of epiphytes. Tropical
montane evergreen forest, known as shola forest,
occurs at higher elevations of the Western Ghats
and its associated hill range in southern India. It
is discontinuous and patchy, usually restricted to
sheltered valleys, hollows and depressions, and
surrounded by grasslands. Some of the main forest
types in the area are wet evergreen forest, sub1

tropical hill forest, montane wet temperate forests,
mixed deciduous, montane evergreen (shola grassland) (see also Champion & Seth 1968; Hockings
1989; Mohandass & Davidar 2009).
For south India there are several provincial
liverwort loras, including monumental works on
liverworts by Montagne (1842) and Gottsche et al.
(1845–1847). Many species are given in revisions of
Indian Cheilolejeunea (Asthana et al. 1995), Indian
Metzgeriaceae (Srivastava & Udar 1975a), Indian
Brachioelejeunea (Awasthi & Srivastava 1988), Indian Fossombroniaceae (Srivastava & Udar 1975b),
Indian Anueraceae (Srivastava & Udar 1976);
Indian hornworts (Asthana & Srivastava 1991), Indian Cololejunea (Asthana & Srivastava 2003),

2002), Indian Lopholejeunea (Awasthi et al. 2000)
and a global revision of Cyathodium (Srivastava
& Dixit 1996). There are recent papers on different aspects of the bryophytes of southern India

The Nilgiri Hills of Tamil Nadu host a valuable
gene pool and signiicant bryodiversity. Preliminary reports on the liverworts of the area appeared
in the middle of the 19th century, based largely
on collections made by Europeans. Montagne’s
(1842) pioneer work on bryophytes of the Nilgiri Hills mentioned some hepatics, followed by
Gottsche et al. (1845–1847) and later by Mitten
(1861) who provided the irst documentation of
the liverworts of the Nilgiri Hills and described
20 species. Most of his names have been replaced
due to changes in their systematic position. Chopra
(1938) also listed several liverworts from the area.
To extend our knowledge of the bryophytes of the
Nilgiri Hills, we made an exhaustive survey of the
entire area, collected and identiied representative
specimens, and made a detailed analysis of their
diversity in the area on the basis of fresh collections and a critical survey of earlier reports and
collections available in the Lucknow University
Hepatic Herbarium (LWU) or overseas herbaria
including NY, G, FH, NICH, STR and JE. The
survey produced some noteworthy developments
in the systematics of the bryophytes of remote
localities in the Nilgiri Hills.
materIal and
methods
We collected and studied nearly 7000 herbarium specimens (mainly Hepaticae and Anthocerotae). They are
preserved in the Bryophyte Herbarium, University of
Lucknow (LWU). As different species grow in different
seasons, generally we collected samples in summer and
winter every year from 2000 to 2008 in the Nilgiri Hills,
also making ecological observation in the ield. At the
same time we studied herbarium accessions collected
by earlier workers. We identiied and authenticated several taxa from type/authentic specimens obtained on
loan from different International herbaria (FH, G, JE,
NICH, NY, STR) and exsiccatae (Hepaticae Selectae et
Criticae edited by Fr. Verdoorn; Hepaticae Japonicae
edited by S. Hattori). The treatment of taxa mainly follows Schuster (1984), Inoue (1984), Gradstein et al.
(2002), So (2003), Engel and Merrill (2004), Zhu and
Gradstein (2005) and Fuselier et al. (2011).
results
and dIscussIon
This work presents 169 taxa belonging to 58
genera and 31 families of Hepaticae and Anthocerotae. Seventy-ive of the 169 taxa are reported
here as obligate epiphytes, mostly members of
the Plagiochilaceae, Porellaceae, Frullaniaceae,
Lejeuneaceae, Radulaceae and Metzgeriaceae. The
liverwort lora of the Nilgiri Hills consists of two
phylogenetically related classes: Jungermanniidae
and Marchantiidae. The Jungermanniidae include
43 genera and 151 species under 9 suborders and
23 families, of both thallose and leafy organization, belonging to Metzgeriales (with 5 genera
and 13 species) and Jungermanniales (a highly
diversiied group with 38 genera and 143 species).
The class Marchantiidae includes 12 genera and
28 species under 2 suborders and 8 families in
the area, while class Anthocerotophyta includes
3 genera and 5 species under 2 families (Tables 1
& 2, Figs 1–18).
During this study we discovered 8 liverwort

ecologIcal observatIons
In terms of habitat preference, the liverworts and
hornworts of Nilgiri can be grouped as terrestrial or epiphytic. Apart from soil-covered rocky
slopes and dense broadleaved forests, the Nilgiri
Hills also have a number of waterfalls, providing
favorable climate and topography for a variety
of terrestrial bryophytes, the predominant form.
Springs, ponds, streams, pools, falls, seeps and
dripping water create extremely wet conditions, as
found at Laws Falls, Pykara Waterfalls, St. Catherine Waterfall and Kalahatti Waterfall, which
support the growth of taxa such as Dumortiera
hirsuta, Pallavicinia lyellii, Riccia luitans, Riccardia levieri, Phaeoceros spp. and Anthoceros
spp. The steep slopes and rocks of the entire region
favor saxicolous vegetation such as Asterella wallichiana, A. khasiana, exormotheca ceylonensis,
Targionia spp., Plagiochasma spp. and Reboulia
hemisphaerica. Some leafy liverworts including
Jungermannia lanceolata, J. tetragona, J. truncata, Notoscyphus lutescens., Cephaloziella sp.,
Cephalozia sp, Lophocolea spp., Heteroscyphus
argutus, H. perfoliatus, Lethocolea javanica, Plagiochila acuta, P. indica and Porella acutifolia are
found in grassland or on soil-covered rocks. Some
terricolous taxa grow as small turfs (Jungermannia
sp., Hebertus spp., Gottschelia schizopleura) and
mats (Lunularia cruciata, Marchantia sp., Pallavicinia lyellii).
The epiphytic bryophytes of Nilgiri Hills are
signiicant in terms of number but also phytosociology. They are found mostly where the conditions

are humid. The entire region of Dodabetta, Pykara
and Mukuruthy National Park receives ca 1200
mm precipitation annually. The epiphytic liverworts of the area form corticolous and epiphyllous
communities. The bark characteristics of the phorophyte – bark pH (always slightly acidic), bark
texture (smooth, rough), exposure to the physical
environment, tree age – play an important role
for corticolous communities. As a habitat for epiphytic liverworts, a tree can be broadly divided
into three regions: the base (up to 50 cm above
soil level), characterized by the growth of species
of Lophocolea, Heteroschyphus, Plicanthus, Lejeunea discreta; the trunk region with large primary
limbs, which host liverworts such as Ptychanthus,
Radula, Lopholejeunea, Porella, Plagiochila and
Frullania; and twigs and small secondary branches
with leaves, providing substrate for liverworts such
as Metzgeria spp., Lejeunea spp., Frullania tamarisci, Plagiochila spp. and Cheilolejeunea spp. The
epiphyllous forms are most typical and require
more relative humidity. Here they are restricted to
the leaves of young trees. Different life forms of
epiphytic liverworts were recorded in the Nilgiri
Hills: short turfs (Lejeunea spp), pendants (Frullania tamarisci, Ptychanthus striatus), wefts (Bazzania tridens), mats (Radula spp., Leucolejeunea
sp.), fans (Porella perrottetiana) and dendroid
forms (e.g., Plagiochila fruticosa). The liverwort
diversity of the Nilgiri Hills is also affected by the
altitudinal gradient, as some characteristics of the
taxa may be governed by environmental factors.
In the lower Nilgiri foothills the representation of
terrestrial liverworts is at maximum; the absence
of epiphytic liverworts in lower areas may be attributed to the drier conditions there: lower humidity, moisture and dew. With increasing altitude
the temperature drops and relative humidity rises,
enhancing the growth of epiphytic liverworts.

Human activities and population pressures coupled with the developing tourism industry in the
area have changed the natural vegetation, posing
a serious threat to the survival of a number of the
region’s loristic elements. The inlux of tourists
indirectly affects the environment. Ooty, a major
tourist destination, attracts great numbers of tourists
the year round. Any environmental impact in major
urban areas at higher elevations such as Ooty, Coonoor and Kotagiri can affect sites at lower locations
(Daniels 1992). Many hotels and other tourism facilities have been constructed. Continuous trafic

has produced heavy automobile pollution in the
area. Grazing is also taking its toll in areas like
Masinagudi, which is a livestock hub with an almost 1:1 ratio of cattle to humans (Daniels 1996).
Free grazing in such areas poses a constant threat
to surface lora. The slopes of the Nilgiri forests
are being cleared for agriculture, destroying forest
patches and consequently the epiphytic lora, and
also increasing the threat of landslides, which are
more common now than earlier.
Observations during ield survey work in the
area in recent years have revealed the absence of

Limpr., Schistochila aligera (Nees & Blume) Jack
& Steph., S. glaucescens (Hook.) A. Evans and S.
philippinensis (Mont.) Jack & Steph., which have
not been re-collected since their original discovery
in the area. A number of other taxa [e.g., Cheilolejeunea udarii, Cololejeunea nilgiriensis, exermotheca
ceylonensis Meijer, Plagiochila gracilis Lindenb.
Plagiochila sisparensis Steph., Reboulia hemisphaerica (L.) Raddi] are near extinction in the area
due to their very low frequency of occurrence and
habitat change.
Some endemic taxa, for example Metzgeria
nilgiriensis, Plagiochila sisparensis, Radula nilgiriensis, Taxilejeunea nilgiriensis, Microlejeunea
udarii, Gongylanthus indicus, Telaranea indica,
Chonocolea schusterii, Lejeunea perrottetii,
Herbertus nilgiriensis, Cheilolejeunea udarii
and Archilejeunea minutiloba, face the maximum
risk of extinction because they have so few localities. Some taxa which are known from other
countries but whose distribution within India is
restricted to the Nilgiri Hills (e.g., Lethocolea
javanica, Plagiochila beddomei, Gottschelia
schizopleura, Plagiochila junghuhniana) are also
threatened.
Bryophytes, though the second-largest group of
terrestrial plants, have received much less attention
than vascular plants in conservation and protection planning. Some liverwort species urgently
require protection and conservation to save them
from extinction. Habitat destruction eliminates
bryophytes earlier than many other phanerogams
because they are more sensitive to environmental
change. The study area, Nilgiri, is illed with lush
green vegetation. Tropical evergreen trees occur
at high frequency and density, providing an excellent environment for growth of bryophytes; they
may serve in in situ conservation of these plants.
Changes in the habit, growth rate and growth pattern of a particular species can be monitored over
a period of several years and the data thus collected can be used to predict the growth potential
of bryophytes during climatic change in the area.
Some rare bryophyte species may be grown in
a natural conservatory such as the Government
Botanical Garden at Ootacamund and Sims Park
at Coonoor.
