APPENDIX G.--BOTANY.
BORAGINACE1E.
EUPLOCA CONVOLVU[LACEA, 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.
ERITRICHIUM 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 (I. 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 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.
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.
POLEMONIACEBE.
PHLOX PILOSA, Linn.; Benth., in DC. Prodr. 9, p. 305. Sources of
the Trinity; May.
PRLMULACEAE.
DODECATHEON MEADIA, Linn.; Pursh, Fl. 1, p. 136; DC. Prodr. 8,
p. 56. Sources of the Trinity; fl. May.
SANTALACELE.
COMANDRA TJMBELLATA, Nutt. Gen. 1, p. 157; Hook. Fl. Bor.-Am. 2,
p. 139, t. 79, f. A; Torr. Fl. N. York, 2, p. 160. Thesium umbellaturn,
Linn. Tributaries of the Red River; May. There are few plants
that have a wider range in latitude and longitude than this.
