Index to the Enumeration of the Orchidaceae of Sumatra, by J.J. Smith. At the Rijksherbarium there was a handwritten copy compiled by the late Dr. J.J. Smith of his important enumeration of Sumatran Orchids, published in Fedde, Repertorium 32 (1933) 130-386, which was obviously for reasons of economy not printed. The author left a note to the Librarian of the Rijksherbarium saying that it is indispensable for consulting this work, as many orchid names were here reduced to synonymy for the first time. This is now available for orchidologists and libraries in stencilled form in the same format as the Enumeration, with the Library of the Rijksherbarium, Schelpenkade 6, Leyden, Holland.
