adds some four hundred species to the known flora of Cuba, 
most of which are undescribed and new to science, a result well 
worth the time and cost entailed. Some of these I propose to 
describe myself, and to submit others to associates and corre- 
cea ts for description. The greater number of novelties in- 
habit the mountainous portions of the Province of Oriente, 
explored by Dr. J. A. Shafer in 1909, and 1910 and 1911; the 
region next most prolific in new species is the mountainous part 
of Santa Clara, explored by myself, with Mrs. Britton, Professor 
F. S. Earle and Mr. Percy Wilson in 1910; and other new types 
are found in the collections made elsewhere. Important addi- 
tions to knowledge of geographic distribution of plants have also 
been made 
The field is so evidently unexhausted, that I propose to con- 
tinue Cuban exploration, as previously authorized, and I have 
commissioned Dr. Shafer to proceed to the Province of Pinar 
del Rio for two months’ collecting, and thence to Santa Clara 
for one month; I desire to personally study portions of Oriente 
not yet visited by any of our collectors or by other botanists 
and to make this exploration in March and April of 1912. 
Opportunity was taken during my visit to these great British 
institutions to obtain information relative to the type specimens 
any American plants, for use in ‘‘ North American Flora” and 
elsewhere; for reference to some literature of botany not con- 
tained in our library; for observations on variegated plants for 
the use of Professor Harper in his forthcoming investigation on 
this interesting topic; and for methods of cultivation of many 
species. 
rs. Britton continued her studies of mosses both at Kew and 
at the British Museum and obtained data of importance for use 
in the forthcoming first bryological part of “North American 
Flora.” We took with us parcels of duplicate West Indian 
mosses for both institutions, as exchanges. She made pleasant 
visits to Dr. Braithwaite in London, Mr. Dixon in Northampton 
and Mr. Nicholson in Lewes for consultation relative to bryo- 
logical questions of mutual interest, as well as to the Misses 
Mitten, at Hurst Pierpoint; it will be remembered that the moss
