656. TWO NEW SPECIES OF SAINTPAULIA FROM THE ULUGURU MOUNTAINS, TANZANIA

摘要

Two new endemic species of Saintpaulia, S. ulugurensis Haston and S. watkinsii Haston (Gesneriaceae) are described from the Uluguru Mountains. Their discovery emphasises the need for additional floristic work to be carried out in this area and supports the calls for strong conservation measures for the fragile forest habitats of Tanzania.
