Bryoflora of Obudu Cattle Ranch in Nigeria.

Obudu cattle ranch in Cross river state, Nigeria has a diversity of bryophytes species. The ranch stretches between an altitude of 751m (at the bottom) and 1595m at the peak. A survey and assessment of the bryoflora of Obudu cattle ranch was made. A total of 140 samples were collected by the use of a scalpel and identification was made by the use of an Olympus microscope. In all, 35 families were identified. 27 families were mosses, 7 families of liverworts and 1 hornwort species. 8 samples were unidentified. High species richness was recorded at 1581m which corresponded to the Becheve Nature Reserve. The newly discovered species which are not in the check list of bryophyte species previously recorded for Nigerian include: Bryum  alpinum var. alpinum; Hypnum lacunosum var. lacunosum; Hypnum  cupressiforme  var. filiforme ; Hypnum  cupressiforme var. cupressiforme ; Hypnum  cupressiforme var. tectorum; Isopterygium           sericifolium; Campylopus  jamesonii; Campylopus  hildebrandtii; Lindbergia  patentifolia; Sematophyllum  subbrachytheciiforme; Funaria  perlaxa; Pilotrichella  cuspidata; Papillaria  africanum; Pilotrichella  ampullaceae; Rhizofabronia  perpilosa; Fabronia  abyssinica; Fabronia  pilifera; Lopidium  struthiopteris; Racopilum  africanum; Prionodon  ciliates; Cyclodictyon  dixonianum; Cyclodictyon  brevifolium; Porothamnium  stipitatum; Porotrichum  usagarum; Trachyphyllum  inflexum; Fissidens  androgynus; Philonotis  fontana; Hedwigidium  integrifolium; Racomitrium  lamprocarpum; Leucobryum  madagassum; Cryphaea  robusta; Daltonia  latolimbata; Leptodontiopsis  fragilifolia; Hennediella stanfordensis; Hylocomnium            splendens; Plagiomnium  rhynchophorum; Ceratolejeunea  calabariensis; Ceratolejeunea  diversicornua; Lejeunea  cantabrigiensis; Haplolejeunea  cucullata; Cheilolejeunea  trifaria; Plagiochilla  pectinata; Plagiochilla  terebrans; Plagiochilla  moenkemeyeri; Plagiothecium   nitens; Frullania  serrate; Mastigophora  diclados; Marchantia  polymorpha; and Phaeoceros   carolianus. In all, there are 37 mosses, 12 liverworts and 1 hornwort. The discovery of the hornwort in Nigeria is reported for the first time in literature in these studies. The altitudinal variation has an effect on the species diversity of bryophytes in the study site with more species present at higher altitudes. The research work on this location will add to the dearth of information on Nigerian bryophytes.
