402); Perak (Wray). Distrit). All warm regions. Xative name 

 " lUimput Tulong Siniadok/' " Eumput Hijau,'"" " Rumput Patah 

 Siku." The common form has glabrous spikelets, often in 3 or 4 

 rows, but forms with very pul)escent spikelets occur. The cultivated 

 Indian form P. Kara, Willd. I have not seen here, and except in the 

 matter of slendcrness of stem, breadth of leaves and such characters 

 due to habitat, the local form here varies but little. 



I have omitted the greater part of the very extensive synonymy 

 of this common plant, upwards of 30 synonyms, which are to be found 

 in the Flora of British India. 



2. P. roxjUGATUM, Berg. Act. Holm. VII. 129. t. 8. Stolo- 

 niferous, with long rooting stolones rather stout. Stems 1-2 feet 

 tall, simple or branched leafy slender. Leaves acuminate 6 inches 

 long tl- wide linear lanceolate edges ciliate, as is the mouth of the 

 sheath. Peduncle very slender, with two very narrow divaricating

 bably introduced. 



Singapore; Johor; Malacca; Perak (Wray); Pahang: Pekan 

 (Eidlcy) ; Penang (Curtis 493). Distrib. Tropical regions of both 

 hemispheres l)ut probably introduced from South America. Owing 

 to its adhesive spikelets," it is carried about all over tiie country at- 

 tached to the clothes of natives. I have seen it above Padang Batu in 

 Mount Ophir growing in a crack of the rock at the regular washing 

 place of the natives, undoubtedly brought up there from the plain 

 country.
