{From the Botanical Section of the Biological Laboratory, Bureau of 



Science, Manila, P. I.) 



The preceding number of this series was published in the early 

 part of the present year,- and the present contribution is essen- 

 tially like its predecessors. Seven genera are for the first time 

 credited to the Archipelago, Avena, Polytoca, Angelesia, Glypto- 

 petalum, Ochrocarpus, Asystasia, and Polytrema. Sixty-two 

 new species are described in various families, while 18 species 

 previously described from extra-Philippine material are for 

 the first time credited to the Archipelago. The total additions 

 to the Philippine flora in the present paper are eighty species. 

 Some reductions are made, and the synonymy of some species is 

 discussed, resulting in a few cases in the substitution of older 

 specific names for those in more general use. All proposed 

 changes in nomenclature are in accordance with the rules of the 

 International Botanical Congress.

This European species is now widely distributed in Asia, northern Africa, 

 and North America, a weed of cultivation. It has previously been recorded 

 from the Philippines by F.-Villar, but his record has not before been verified. 

 It is apparently a casual plant here and may or may not persist.
