140 UNITED STATES AND MEXICAN BOUNDARY. 
Sierra San Luis, Chihuahua, September; Schott. No. 1653, Wright, seems to be only a narrow- 
leaved form of this species. 
LITHOSPERMUM LONGIFLORUM, Spreng. Syst. 1, p. 554. L. incisum, Гейт. l. c. Pentalophus 
longiflorus, DC. Prodr. 10, р. 86. Banks of streams, cafion of Guadalupe, Sonora, April; 
Captain E. K. Smith. Near the Copper Mines, Ben Moore, Santa Barbara, and Mimbres, April; 
Bigelow. Apache Springs, March; Parry. Hueco mountains, Texas, and Ojo de Vaca, Chi- 
huahua; Thurber, Nutlets ovate, white and shining, marked more or less with shallow pits. 
After flowering the = becomes more branched, and produces narrower and more crowded 
leaves. 
LITHOSPERMUM BREVIFLORUM, Znglm. & Gray, Pl. Lindh. p. 44. Western Texas; (Wright, Nos. 
1560 and 1561.) Nutlets as in the last. 
LITHOSPERMUM Матамовкхве, DC. Prodr. 10, p. 76. On the Lower Rio Grande; (Wright, No. 
1564.) Near Monterey, Mexico; Dr. Edwards and Major Eaton. Our plant agrees very well 
with Berlandier's own specimens. 
AMSINCKIA LYCOPSOIDES, Lehm. Del. Sem. Н. Hamb. 1831, p. Т; DC. Prodr. 10, p. 117. Jour- 
nado between Tucson and the Gila, Sonora; also grassy places near San Diego, California, 
March; Parry. 
AMSINCKIA INTERMEDIA, Fisch. & Mey. Ind. 2, Sem. Petrop. 1835, p. 26; DO. 1. c.  Alluvions 
of the Gila, Sonora, and near San Diego, California, March; Parry. The insertion of the 
stamens is not constant in this genus. In the same species they are sometimes placed near the 
base of the corolla; sometimes in the upper part of the throat. Perhaps allthe species with 
rugose nutlets are forms of A. lycopsoides. | 
ERITRICHIUM GLOMERATUM, DC. Prodr. 10, p. 131. Myosotis glomerata, Nult. Gen. 1, р. 112, 
一 Hook. Fl. Bor.- Amer. 2, p. 82, t. 162. Near El Paso and Doña Ana, March—April. (No. 1566, 
Wright.) New Mexico; Fendler. No. 632. About a foot high. Root perennial. Hairs of the 
. calyx and of the upper leaves yellowish. Nutlets closely fitted to each other, forming a depressed

ши 
globose fruit, margined; the back strongly rugulose transversely and more ог less verrucose. 
Var. HISPIDISSIMUM is more hispid, and seems to be biennial. Common in New Mexico. 
ERITRICHIUM JAMESII, Torr. in Marcy Rep. p. 294. Myosotis suffruticosa, Torr. in Ann. Lye. 
New York, 2, p. 225. Near the Copper Mines, New Mexico, and Mule Springs, March— 
June, El Paso, and Journado del Muerto, March—April; Thurber. Dry ravines, San Luis, 
Sonora, April; Captain E. K. Smith. | 
ERITRICHIUM HELIOTROPIOIDES. Antiphytum пано рийн, Alph. DC. in Prodr. 10, p. 122. 
Sandy shore of the Rio Grande at Eagle Pass; Schott. No. 1572, Wright. Valley of the Lim- | 
pio; Bigelow. Dry plains southwest of Escondido, May, (1847,) and Saltillo, (1848 and 1849;) | 
Dr. Gregg. Our specimens agree in all respects with Berlandier’s. The leaves аге not opposite, |

and we have little doubt that the plant should be referred to Eritrichium, $ Rutidocaryum. 
The root is annual, but in old plants the stem becomes hard and ligneous.
