The four specimens quoted above, all collected by Dr. Kerr on 

 Doi Sootep, illustrate remarkably well the polymorphic nature of 

 this species. No. 1181 is a tall plant growing to a height of 

 10 dcm., with long glaucous and slightly hairy leaves and glabrous 

 inflorescence. No. 1896 is a medium-sized plant with shorter 

 obtuse broad (3 mm. broad) leaves. No. 2239b is a very small 

 and slender plant, about 12 cm. high, with very narrow leaves 

 (0*5 mm. broad). No. 2649 is a tall plant, growing to a height of 

 9 dcm., with the stem and inflorescence distinctly hairy and the 

 leaves (blades and sheaths) densely white pubescent. This last 

 plant is evidently Fimbristylis tomentosa, Vahl which C. B. Clarke 

 considered only a form of F. diphylla, Vahl. All the above plants 

 have the characteristic longitudinally-ribbed nut of F. diphylla.
