SECRETARY’S REPORT Dil 
Dr. Richard S. Cowan, associate curator of phanerogams, visited 
the Gray Herbarium of Harvard University and the New York 
Botanical Garden in November 1958 in connection with his work on 
the Index Nomina Genericorum, the flora of Santa Catarina, and 
plants of the Guyana Highland. At the second of these institutions 
he conferred with Drs, Maguire and Wurdack for the purpose of 
outlining in a general way the structure and content as well as the geo- 
graphic limits of the proposed Flora of Guyana. Dr. Cowan also 
represented the department of botany on the 1959 Smithsonian-Bredin 
Expedition, 
In connection with her continuing studies of Ormosza and other 
genera of the family Leguminosae, Dr. Velva E. Rudd, associate 
curator of phanerogams, visited New York and Philadelphia in No- 
vember and Chicago in December 1958. At the New York Botan- 
ical Garden, the Academy of Natural Sciences of Philadelphia, and 
the Chicago Natural History Museum she surveyed the available study 
materials in groups of interest to her, and selected specimens for 
borrowing. 
Between August 20 and 24, 1958, C. V. Morton, curator of ferns, 
participated in the annual summer foray of the American Fern So- 
ciety in southern Ohio, after which he attended the meetings of the 
American Institute of Biological Sciences at Indiana University. 
In November and December he studied in the herbarium and library 
of the Harvard University Herbarium in Cambridge in order to check 
the bibliographical citations for the Index Nomina Genericorum. 
In connection with the same project he also visited the New York 
Botanical Garden. 
In July 1958 Dr. Mason E. Hale, associate curator of cryptogams, 
spent several days in southwestern Virginia and the adjacent area 
of Tennessee in company with R. R. Ireland, assistant curator of 
cryptogams, in pursuance of his fieldwork on Appalachian lichens. 
This study, undertaken with the aid of a grant from the National 
Science Foundation, has resulted in the collection of many specimens 
of lichens in the area. In February 1959 Dr. Hale spent several 
days in the cryptogamic herbarium of Duke University, examining 
lichens in the very important Harmand Herbarium with particular 
reference to the study of the lichen flora of the central Appalachian 
Mountains. In May he continued his work on the same project by 
studying in the rich cryptogamic library and herbarium of Harvard 
University. 
Dr. Herbert Friedmann, head curator of the department of zoology, 
spent the period between July 7 and 26, 1958, in England, principally
