Epiphyte host relationship of macrolichens in the tropical wet evergreen forests of Silent Valley National Park, Western Ghats, India

摘要

The paper deals with epiphyte host relationship of macrolichens in the west-coast tropical evergreen forests and the subtropical broad-leaved hill forests of Silent Valley National Park. Of the 104 taxa recorded in the two habitats, 69 species occurred in the west-coast tropical evergreen forests and 68 species in the subtropical broad-leaved hill forests. These forest types mostly support cyanolichens. Lichens prefer several host species in the west-coast tropical evergreen forests, but the percentage of occurrence of macrolichens on hosts is greater in the subtropical broad-leaved hill forests. Host species such as Palaquium ellipticum, Litsea floribunda, Antidesma montanum, Poeciloneuron indicum, Myristica montanum, Euonymus angulatus, Flacourtia montana were found to be important host plants.
