DISTRITO FEDERAL: brook in cloud forest on seaward side of road leading to Carayaca, 2.5 km below junction of Carayaca-Colonia Tovar road, 2100 m, Steyermark 91762 (VEN) ; summer forests of Avila, Delgado 2 (VEN).

Nevertheless, it appears nearer to the section Ibatia (1941). Matelea manarae is closely related to M. costanensis, described above. From this it differs in the pubescent lower surface of the leaf, longer peduncles, longer and differently shaped sepals, somewhat different corona, and longer pollinia. The species is named in honor of my friend, Professor Bruno Manara, dedicated explorer and lover of the mountain forests north of Caracas. LITERATURE CITED Webster, G. L. 1975.

SYMPOSIUM ON ENDANGERED AND THREATENED PLANTS AND ANIMALS OF VIRGINIA

May 19-20, 1978

The Symposium is sponsored by the Center for Environmental Studies, Virginia Polytechnic Institute and State University, Blacksburg, Virginia 24061. The registra- tion fee is $17.00 per person. Lodging is available at $14.00 single and $18.00 double occupancy.

The primary purpose of the Symposium is to generate a carefully considered, well documented list of Virginia flora and fauna deemed endangered, threatened or other- wise of concern. The proceedings will be published and will include all data compiled (status, distribution, habitat, and relevant life history data) and it is expected to contain suggestions for research, for education, for minimizing impacts on the species involved, and for management.
