In the course of his studies on the biodiversity and ecology of African forests, the Bayreuth biologist has established vegetation study plots on numerous mountains. On each plot, he has completely recorded and documented the species composition of the vegetation. In total, the resulting database now comprises several thousand vegetation records. Typical of all tropical mountain rainforests are the epiphytes, which play an important role in water balance and biodiversity. "A lot of luck is involved in finding such small epiphytes as the newly discovered orchid: If it had not bloomed at the right time, it would certainly have gone unnoticed," says Hemp. In the neighboring Tanzanian Nguru Mountains, which like the South Pare Mountains belong to the Eastern Arc Mountain chain, he found another previously unknown orchid species from the large genus Polystachya during his recent research visit.
Internationally, the leading specialist on orchids in East Africa is Dr. Phil Cribb of the Royal Botanical Gardens in Kew, London. He is the author of the orchid identification volumes of the "Flora of Tropical East Africa". "After I could not clearly identify the orchid discovered in the South Pare Mountains using these volumes, I asked him for his expertise. Together we then described the new species and also chose the name Rhipidoglossum pareense," reports Hemp, who visits the herbarium at the botanic garden in Kew usually once a year. "The herbarium at Kew contains the world's most comprehensive collection of plants from East Africa. The long-standing collaboration with the outstanding connoisseurs of African flora there is a valuable support and always a stimulus for my own research work. Such comprehensive collections, which document flora and vegetation from earlier decades and centuries, are indispensable for current biodiversity research," says the Bayreuth plant systematist.
