Sierra San Luis, Chihualiua, September; Schott. ISTo. 1653; Wright, seems to be only a narrow- 

 leaved form of this species. 



LiTHOSPERMUM LONGiFLORUM, Sproig. Syst. 1, p. 554. L. incisum, Lehm. I. c. Pentaloplius 

 longiflorus, BG. Prodr. 10, p. 86. Banks of streams; canon 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 Yaca, Chi- 

 huahua; Thurher. Nutlets ovate, white and shining, marked more or less with shallow pits. 

 After flowering the plant becomes more branched, and produces narrower and more crowded 

 leaves.

 1560 and 1561.) Nutlets as in the last.

LiTHOSPERMUM MatamorensE; DG. Prodv. 10, p. 76. On the Lower Eio Grande; (Wright, No. 

 1564.) Near Monterey, Mexico; Br. Edwards and Major Eaton. Our plant agrees very well 

 with Berlandier's own specimens.

Amsinckia intermedia, Fisch. (b Bley. hid. 2, Sem. Petrop, 1835,^. 26; BO. ?. 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 all the species with 

 rugose nutlets are forms of A. lycopsoides.

 Winght.) New Mexico ; Fendler. No. 632. About a foot high, Ptoot perennial. Hairs of the 

 calyx and of the upper leaves yellowish. Nutlets closely fitted to each other, forming a depressed 

 globose fruit, margined; the back strongly rugulose transversely and more or less verrucose. 



Var. HisPinissiMU3i is more hispid, and seems to be biennial. Common in New Mexico.

Br. Gregg. Our specimens agree in all respects with Berlandier*s. The leaves are not opposite, 

 and we have little doubt that the plant should be referred to Eritrichium, § Eutidocaryum. 

 The root is annual, but in old plants the stem becomes hard and ligneous.
