It still remains a question whether this plant should 

 bear Delile^s name or Pollini^s name, according as the 

 one or the other had priority in publication, as has been 

 pointed out by Prof. Ascherson in 'Atti della Society 

 Italiana/ vol. x. p. 267, where he shows that the descrip- 

 tion of the plant of Pollini was certainly published in 

 18 14; whilst the Memoir of Delile, although perhaps 

 printed in 18 13, was not published until some later year. 

 I cannot elucidate this point further, as my copy of 

 Delile has no titlepage, and my edition of PoUini's 'Flora 

 Veronensis^ is that of 1824. Pollini's herbarium=specimen 

 of the Italian plant is preserved among the possessions of 

 the Society of Naturalists of Rhenish Westphalia, in 

 Bonn. 



The Italian plant is not the same as Robert Brown^s 

 Naias tenuifolia, Prodr. Fl. Nov. Holland, p. 545, published 

 in 1 8 10, on account of the entirely different structure of 

 the male flower (see Plate VI. fig. 15); otherwise the 

 name would have taken precedence of Pollini's and 

 Delile's. 



Whether the plant found in Japan, at Yokohama, is 

 identical with Naias graminea, Del., is uncertain ; but the 

 description of it by Herr C. J. Maximowicz may stand for 

 the Lancashire plant : — " Mollis elongata, foliis verticil- 

 latis patentibus rectis argute spinoso-serrulatis, apice 2-3 

 cuspidatis, dentibus incurvis 1-cellulosis minutis; stipulis 

 distinct] ssimis lanceolatis foliaceis folii ad instar serrulatis ;
