except on the margin, which is somewhat ciliate with hairs. 

 Floiver terminal, erect, about half an inch in diameter. 

 Calyx 10-cleft, hairy; exterior segments a little shorter, 

 lanceolate, acute ; interior segments ovate-lanceolate. Co- 

 rolla 5-petalled, yellow -^petals nearly round, very entire, 

 about one-third longer than the calyx. Stamens very nu- 

 merous ; filaments smooth ; anthers round. Receptacle 

 hairy.

This species appears to be quite distinct from any described

larum" ofLehmann, published in 1820 ; or in any subsequent 



work with which I am acquainted. 



5. Myosotis nana. Miliars? 

 M. sericeo-villosissima, foliis ovatis oblongisque obtusis 



integerrimis congestis, racemo paucifloro, seminibus laevius- 



culis, margine integerrimis. 



Plant cespitose, perennial, less than an inch in height. Stem
