NEW PLANTS FROM VENEZUELA 
By S. F. Biake. 
At intervals during the last nine years Mr. Henry Pittier, until 
recently a member of the staff of the United States Department of 
Agriculture, has made large collections of plants in Venezuela. His 
specimens, amounting to several thousand numbers, although as yet 
only partly identified, have added largely to our knowledge of the 
flora of that country. The new species collected by Mr. Pittier and 
described in the present paper are derived in part from his earlier 
collections and in part from the material forwarded by him since 
his return to Caracas in 1919. 
Nearly half of the new species here described are from the small 
but very interesting collections made by Dr. Alfredo Jahn in the 
high paramos of Tachira and Mérida at various dates during the 
past dozen years. Several new species collected by Dr. Jahn were 
described a few years ago by Mr. Paul C. Standley, but a consider- 
able amount of the material has remained unnamed, and many 
species not before represented have been found in Dr. Jahn’s recent 
collections. 
Of the new plants here described the most interesting are three 
of the Asteraceae. Riencourtia ovata belongs to a genus new to 
Venezuela, and Otopappus australis to one new to South America. 
Podocoma bartsiaefolia i is the only northern representative of a genus 
with several species in Brazil, extending into Uruguay and P ara- 
guay, and a single outlier in Australia. 
The description of a new moss collected by Mr. Pittier and named 
by Mr. R. S. Williams is included in this paper at the request of 
the author.

than 1 cm. long, bearing scattered radicles beneath; leaves ecostate, entire,
