A loral area of 4.5 ha was surveyed ill coffee alld 1101I-coffee forest vegetafion. Fifty salllplillg plofs, each 30 III X 30 III (900 11/ 1), were used for the purpose of daw col/eeliOIl. A lotal of 59 species of vascular epiphyte:,' were recorded alld of which 34(59%) were holo ep'j)hyte:", 111'0 (4%) were hemi epiphyles alld 22 (37%) :,pecies were accidenwl vascular epiphytes. To :,·tudy Ille allitlldinal dislribulioll of vascular epiphYles. altitudes were classified into higher >2000, //Iiddle 1800- 2000 and Jower 1600- 1800//1 a.s.1. accordillg to Shanl/otl- Wiener Index (HI = 3.411) of tJ. alpha dil'ersily file epiphyte COllll111111ily ill the sllldy area is medium. There was a stjlistically sigmjicalll dljerence belween host bark Iype and epiphyte richlless as determined by Olle~way ANOVA (F(3, 91) "'" 21 .833, p = 0.001). The p(w- hoc fesl shows Ihal there is sigllificallf difference of vascular epiphyles riclme.\'S be/lt"eell Slllooll1 bark willi rough jlack and corky bark (P =0,00 I < 0.05), as we/J as rough alld cork bark (p =0.43 <0.05).
