APPENDIX G. BOTANY. 281 



Eritrichium Jamesh. Myosotis suffruticosa, Torr., in Ann. Lye. N. York, 

 2, p. 225 ; DC. Prodr. 10, p. 114. North Fork of Red River ; fl. and fr. June 14. 

 This plant had not been found, till Captain Marcy collected it, since it was dis- 

 covered by Dr. James, in Long's Expedition. It is a genuine Eritrichium, but 

 can hardly be referred to any one of De Candolle's sections of that genus. My 

 description (1. c.) was drawn from old and imperfect specimens, the stems of 

 which were indurated at the base so as to appear suffrutescent. As more com- 

 plete specimens show the plant to be herbaceous, the former specific name is 

 not appropriate. The allied Fendlerian species No. 636 (E. multicaule Torr. 

 Mss.) is very hispid and canescent, with spreading hairs, and throws up several 

 stems from a thick root or caudex. Leaves linea-spatulate and obtuse. Flow- 

 ers on conspicuous pedicels. Fructiferous calyx broadly ovate, nearly erect ; 

 the segments ovate-lanceolate and closed over the fruit. Nutlets truncate at 

 the summit, very smooth and shining.
