Sierra de Naguabo, March 7-9, and those subsequently 
collected by Dr. Shafer in July and August, proved of great 
interest and have been studied and incorporated in the 
herbarium. A hand list of the mosses of Porto Rico has 
been prepared, including 71 genera and 165 species, with 
their habits and ranges throughout North America. It 
would appear from a comparison with the flora of Jamaica 
that either there is still more exploration necessary in the 
eastern and central mountain ranges of Porto Rico or the 
moss flora is less rich in species and genera, since 121 genera 
and 277 species have been listed from Jamaica. 
The hepatics from this year’s collection have also been 
prepared and listed, and 158 packets sent to Dr. A. W. 
Evans, of Yale University, for study. Mr. W. C. Fishlock, 
of the Agricultural Experiment Station at Tortola, in the 
Virgin Islands, has been stationed on Dominica for a few 
months and has very kindly sent us a small collection of 
mosses and hepatics from thatisland. Mr. William Harris, 
of Hope Gardens, Jamaica, Mr. W. E. Broadway, of Tobago, 
and the Christian Brothers, of La Salle College, Cuba, 
particularly Brother Leon, have continued to send us 
duplicates for our sets of West Indian Exsiccati, which we 
hope to distribute at an early date. 
During late winter and early spring, a series of essays 
and compositions on the “Preservation of Our Native 
Plants’? was received from the high schools of Greater 
New York and the public schools of The Bronx, and 
selections from these were printed in the Garden Journal 
as Stokes Prize Essays, each of the schools receiving a 
framed picture of eight colored illustrations of wild flowers 
in special danger of extermination in this region. I have 
also acted as secretary-treasurer of the Wild Flower Preser- 
vation Society of America. 
Mr. Williams, Administrative Assistant, has finished his 
studies of the Philippine mosses and published his enumer- 
ation in the Bulletin. He has also devoted considerable 
time to studying collections received from the National
