This grass has been experimented with as a paper-making 



'material. It was reported in 1908 to be of doubtful commercial 



value when compared with other materials for this purpose, 



.but that it might be used in association with pulp derived from 



other sources (I.e. 1910, p. 205; Agric. Bull. Fed. Malay States, 



,Dec. 1908, p. 587), and later results obtained by the chemical 



analysis show that it gives a good quality cellulose, suitable 



in every way for the manufacture of paper (Kew Bull., 1909, 



p. 57). Experiments show that it gives a good yield of pulp, 



.which bleaches readily, and that when used alone it would be 



suitable for making high-class printing papers, and in conjunction 



with 20 per cent, of rags would produce excellent writing-paper 



(Bull. Imp. Inst., 1918, p. 271). There is a sample of paper-pulp 



or '' half-stuff " of '' Lalang-grass " from Singapore (Ridley, 



1894) in the Museum at Kew. As a paper-making material 



the plant is fully discussed in Kew Bull., 1909, pp. 55--59. 



A perennial; culms 1^-4 ft. long (Fl. Trop. Afr., I.e.), 2 ft., 

 Nupe (Barter; Herb. Kew) ; a stiff-leaved grass with a white, 

 cottony flower-spike, growing in fields and elsewhere after 

 harvest or burning, especially in damp situations, N. Nigeria 

 ,(Dalziel, I.e.) and found in moist, stiff pasture ground, India 

 (Watt, I.e.), on rich alluvial land, Australia (Maiden, I.e.), more 

 or le s of a pest on rubber plantations, Malaya; a great pest 

 to cultivation, Nupe (Barter, I.e.) and a well-known pest in 

 clearings, Yola (Dalziel, Herb. Kew). The plant is a striking 

 one when in flower—" low valleys of this appear like^ distant 

 snow-fields " in Nupe (Barter, I.e.) and " about April or May, 

 the fields, roadsides and railway embankments become white 

 with its silky heads," in India (Watt, I.e.).
