We had regarded this plant as a form of C. canescens, and we are still of opinion 

 that both this and C. mexicana are at most varieties of that species.

[ii. p. 378.] Dr. Gray (Proc. Am. Acad. xx. p. 278, in nota) suggests that 

 Myosotis grandiflora, H. B. K. (Nov. Gen. et Sp. iii. p. 90, t. 199 ; DC. Prodr. x. 

 p. 114), is a species of Krynitzkia, and that the Quitian locality recorded is an error. 

 Schiede and Deppe, according to De Candolle, collected it on Mount Orizaba. It was 

 accidentally omitted from our enumeration, as well as Myosotis albida, H. B. K. 

 (Nov. Gen. et Sp. iii. p. 91 ; DC. Prodr. x. p. 113). Anchusa tuberosa, H. B. K. (I. c. 

 p. 92), is another doubtful Mexican Boraginea.
