Arrou. — A common littoral grass throughout Polynesia, from New Caledonia and tie 

 Fijis to Pitcairn Island. The genus comprises about twelve species, generally diffused in 

 tropical and subtropical regions. Cenchrus echinatus is a very widely spread sea-shore 

 sand-binding plant, and Nadeaud includes it in his Enumeration of Tahitian Plants, but 

 we have only seen Cenchrus calyculatus from Polynesia. The prickly involucres of the 

 inflorescence of these grasses attach themselves to the clothes and other things, and are 

 thus conveyed from place to place. 



Stenotaphrum subulatum, Trin. 



Stenotaphrum subulatum, Trin. ; Baker, Fl. Maurit., p. 440. 



Ki. — It is a little doubtful whether the Ki plant is this species, which inhabits the sea- 

 shores of the Archipelago, Polynesia, and the Mascareue Islands, or Stenotaphrum ameri- 

 canum, Schrank (Benth., Fl. Austr., vii. p. 500), which is found on nearly all tropical and 

 subtropical shores. 



Spinifex squarrosus, Linn. 



Spinifex squarrosus, Linn. ; Miq., Fl. Ind. Bat., iii. p. 474. 



Lakor ; Letti. — An exceedingly common grass on the sandy sea-shores of Tropical 

 Asia, entirely covering large expanses, according to Miquel ; yet it does not appear to 

 extend to Australia, where three other species grow — the following, and one endemic ; the 

 third also inhabiting the coast of New Zealand and New Caledonia. This is the whole 

 area of the e;enus.

Ki.— North and West Australia. The late General Munro named the Ki plant, and 

 noted on the label, "very close to Spinifex squarrosus, except the foliage." Miquel 

 records this species from Timor.
