262 APPENDIX G. BOTANY. 



BORAGINACE^E. 



Euploca convolvulacea, Nutt., in Amer. Phil. Trans, (n. ser.) 5, 

 p. 190 ; DC. Prodr. 9, p. 559. Middle Fork of Red River ; fl. June 23. 

 I am now convinced that my E. grandiflora (Emory's Report, p. 147) 

 is an unusually large -flowered state of the present species. The plant 

 is abundant on the Upper Rio Grande. 



Eritrichittm Jamesii. 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 discovered 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 complete specimens 

 show the plant to be herbaceous, the former specific name is not appro- 

 priate. 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. 

 Flowers 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. 



POLEMONIACE^E. 



Phlox pilosa, Linn.; Benth., in DC. Prodr. 9, p. 305. Sources of 

 the Trinity ; May. 



PRIMULACEJE. 



DoDECATHEOtf Meadia, Linn.; Pursh, Fl. 1, p. 136 ; DC. Prodr. 8, 

 p. 56. Sources of the Trinity ; fl. May. 



SANTALACEiE. 



Comandra umbellata, Nutt. Gen. 1, p. 15*7 ; Hook. Fl. Bor.-Am. 2, 

 p. 139, t. 19, f. A; Torr. Fl. N. York, 2, p. 160. Thesium umbella- 

 tum, Linn. Tributaries of the Red River ; May. There are few plants 

 that have a wider range in latitude and longitude than this.
