twenty-eight full-page paintings were secured, or, about an 
qeuivalent of one painting a day while she was in the field. 
Only flowering plants were illustrated, including two species of 
monocotyledons and twenty-six species of dicotyledons. Alto- 
gether, they represent twenty natural plant-families and twenty- 
six genera. Most of the plants illustrated are rare or local in 
our flora, while four of them are species new to science. Viewed 
geographically, the four novelties, and thirteen other species, 
are endemic in Florida; eleven kinds grow also in the West 
Indies and in Mexico; while two in the latter category range 
well down into South America. 
While gathering specimens for painting from the vicinity of 
Miami, studies on various problems, begun in previous years, 
were continued. Investigations among the Florida cacti were 
continued in our field-work, particularly in connection with 
problems arising through the monographic work of yourself and 
Dr. Rose for the Carnegie Institution of Washington. 
In passing, it may be of interest to state that several years ago 
we knew of but seven species of cacti in Florida, these being 
referred to two genera, four to the genus Opuntia and three, of 
uncertain relationship, to the genus Cereus. Our information 
of this group has so increased, however, that today we have 
definite knowledge of twenty-four species, these clearly constitut- 
ing seven genera. 
Twelve of these species are flat-jointed and represent the 
genus Opuntia, or prickly pears; while the remaining twelve are 
of the columnar or climbing kinds and comprise the six other 
genera. These latter are Selenicereus, with two species; Hylo- 
cereus, with one species; Acantl eus, with one species; [arrisia, 
with five species; Cephalocereus, with two species; and Pereskia, 
with one species. 
It should be mentioned that this record speaks well not only 
for the field work done, but for the opportunities afforded by 
the cactus-plantation in the reservation of Mr. Charles Deering 
at Buena Vista, Florida. Here we have been able to bring to- 
gether, grow, and study all the known cacti not of Florida alone, 
but of the entire eastern United States.
