student from consulting it. The writer presumes that the series is to be contin-

MISCELLANEOUS NOTES 
Mr. H. Pittier, lately of the Bureau of Plant Industry, U. S. Department 
of Agriculture, and now a resident of Caracas, Venezuela, has undertaken ex- 
tensive plant collecting in that country. Lately, he has paid closer attention 
to the Moss flora, which seems to be very rich, since, though no less than seventy- 
nine genera and two hundred and ninety species had been listed previously, 
the small collection already sent Mrs. Britton and Mr. Williams for determina- 
tion contained several interesting additions to said list. 
Four sets of Mr. Pittier 's plants have already been placed, but he would 
like to obtain a few more subscribers, either for the complete series or for the 
mosses only, which would help him in continuing his exploration work in Ven- 
ezuela. It may be added that Mr. Pittier is not without experience as a collector. 
He was the initiator and principal agent in the formation of the rich collection 
of more than 20,000 numbers known as the "Instituto-fisico-geografico de Costa 
Rica" series fTSSy-igos), the mosses of which were worked up by Mr. J. Cardot, 
and his own series (1903-), a complete set of which is in the U. S. Nat. Herbar- 
ium, amounts to-day to more than 10,000 specimens, proceeding from Mexico, 
Ceni:ral America, Panama, Colombia and Venezuela. Fuller information may 
be obtained from Mr. Edward B. Chamberlain or Mrs. Britton.
