NOTES ON PHILIPPINE GRAMINE/E, 



By E. Hackix. 

 {Graz, Austria.) 



The present article, as was the case with the preceding paper pub- 

 lished under this title, 1 has been compiled from notes <nd identifications 

 submitted by Dr. Haekel, the material having been su] plied to him in 

 part for identification and in part for verification of my own determina- 

 tions. In the present short paper, including the species and varieties 

 described as new, 29 species and varieties and 4 genera are added to the 

 Philippine flora, with one exception, all from a collection made in less 

 than a month's time in the highlands of Benguet and Lepanto, Northern 

 Luzon. The very striking character of the collection, other than such 

 more or less characteristic northern types as Pollinia nuda Trill., P. im- 

 bcrbis var. Willdenowiana forma monoslachya Hack., Arthraxon ciliaris 

 Beauv., varieties, A. micro phyllus Hochst., Panicum pedicellate Hack., 

 P. villosum Lam., Calamagrostis anntdinacea Both, var. nipponica 

 Hack., and Brachy podium silvaticum Beauv., is the presence of a series of 

 distinct southern or Australian types, such as Cldonachne biaurita Hack., 

 Pollinia imtans Benth., Andropogon Bailey i F. Muell., A. fragilis B. Br., 

 var. luzoniensis Hack., A. filipendulus Hochst., var. lachnatherus Hack., 

 Ischaemum arundinaceum F. Muell., var. radicans Hack., and Microlaena 

 dipoides B. Br.— (E. I). M.)
