摘要

An extremely rare liverwort (Hepaticae) viz., Southbya gollanii Steph. is described from India and assessed for its status according to the guidelines of IUCN for bryophytes. In recent years, considerable attention has been paid towards the conservation of threatened bryophytes. The initial step was taken by ECCB (1995), which published comprehensive Red Data Book of European bryophytes. Later, an expert group of IUCN for bryophytes, discussed the guidelines for the application of the new IUCN red list categories for the bryophytes (Hallingback & al., 1998). Past few years have witnessed a number of contributions on threatened bryophytes at global level for exploration and preparation of Red List of bryophytes from various territories of the world (Church & al., 2001; Sabovljevic & al., 2004; Kotiranta & al., 1998; Tzvelev, 2000; Vieira & al., 2005; Sergio & al., 2001; Ganeva, 1998; Kucera and Vana, 2003; Rassi & al.,2001;Kubinska & al., 1996; Sergio & al., 1992; Szweykowski, 1992; Jukoniene, 1996;Aleffi & Schumacker, 1995). Apart from these, a world list of bryophytes (Tan & al., 2000) has also been prepared including mosses (38 spp.) and liverworts (45 spp.) Out of these, 3 mosses and 4 liverworts are Indian representatives (Tan & al., 2000). Unfortunately, there is paucity of efforts to explore and mark threatened bryophytes of India. Udar & Srivastava (1983), who provided a list of 85 rare and threatened taxa of bryophytes from India, made the first meaningful report in this direction. This work was particularly important, as it was a kind of first Red List of Indian bryophytes. After a huge gap of several years, two of us (SCS and KKR) had the privilege to study one of the least known species, Isotachis indica Mitt, from India and proposedits possible inclusion in Red Data Book (Srivastava & Rawat, 2001). Recently, another such effort was made by Singh (2008) to enumerate the threatened species of liverworts of India. He (Singh, 2008) provided a list of 12 liverworts and two hornworts with a short note for each on their status. However, a number of the Indian taxa are still inadequately known (even morpho-taxonomical details are unavailable) due to lack of sufficient literature and suitable authentic specimens, which make the scenario worst. This study is an extension of our earlier effort (Srivastava & Rawat, 2001), as it deals with another liverwort, Southbya gollanii Steph. from India, providing full morpho-taxonomic details. It is very rare, as it does not seem to have been collected or reported since its original discovery and is still untraced despite several collection forrays in the area in past few decades. The present study is based on the type specimens obtained from G. It is believed that the present work would inspire students of bryology towards preparation of the "Red Data Book" of Indian bryophytes" and some more people will come up to help achieve this target.
