COGON. 



{Imperata cylindi'ica var. koenigii; I. exaltata.) 



Cogon (Sp.), (Camarines, Antique, Cebu, Iloilo, Pampanga) ; cun 

 (Gad. in Nueva Vizcaya) ; guyun (Isi. in Nueva Vizcaya) ; mimi 

 (Iban. in Isabela) ; panac (II. in Isabela) ;, panao (II.), (II. in 

 Nueva Vizcaya) . 



Cogon grass with its silky-white panicles is well known 

 throughout the Islands, as it is a weed that roots easily in 

 fallow land and is then extremely hard to eradicate. One 

 variety ^ is usually much less than 1 m. high, while the 

 other - grows from 1 to 1.5 m. in height. 



PREPARATION. 



The flower stalks may be prepared as a hat material in 

 the same way as those of vetiver grass. 



USES. 



The flower stalks are used occasionally for hats similar 

 in manufacture to those made of vetiver stalks. The leaves 

 are used at times for roofs and for rope. The Albay schools 

 at the carnival of 1913 showed a round braided mat of cogon 

 which is well adapted for a bathroom mat and for places 

 where a cheap but substantial mat is desired. 



COBBOOT. 



{Ischaenium angusti folium.) 



Cobboot (Cagayan, Nueva Vizcaya, Pangasinan, Ilocos Norte) ; 

 puenig (Ig. in Bontoc). 



The base of the stem of this grass is swollen and woolly 

 and so furnishes an important means of identifying the 

 plant. The stem, varying in height between 60 and 90 cm., 

 is smooth and slender, grooved on one side and bears but 

 few branches. The leaves are 30 to 60 cm. long, 3 to 5 mm. 

 in width, either concave or convoluted, and rough along the 

 margins. In Ilocos Norte the grass is considered to reach 

 its full growth during the months of August and September. 



The flower spikes are soft and downy, erect, either close
