18 BOTANY. 



smooth, green on both sides. Flowers apparently white, about as large as in S. nigrum. Wo 

 are constrained to refer all the forms here noticed to one species, having specimens of interme- 

 diate characters that seem to unite them. The last variety may, however, prove to be a distinct 

 species. . 



SoLANUM FLAViDUM, Torr. in Ann. Lye. N. York, 2, jp. 227 ; and in Marmj's Rep. p. 292. 

 Base of the Chiricahui mountains ; July. Berries orange, the size of a small rifle ball. This 

 is near S. elajagnifolium, Cavan. 



Physalis PUMiLA, Nutt. Trans. Amer. Phil. Soc. (n. ser.) 5, p. 193. Los Playas ; August. 

 This species is omitted by Dunal in De Candolle's Prodromus. 



Datura Metel, Linn, var ? quinquecuspida : limb of the corolla 5-cuspidate with interme- 

 diate more or less acute angles, otherwise as in D. metel. San Bernardino and San Gabriel; 

 April. A common plant in New Mexico, and west to the Pacific. It is called Toloachi by the 

 Mexicans, who are acquainted with its narcotic powers. The leaves vary from entire to coarsely 

 repand-toothed, and are pubescent on both surfaces, especially on the under. The corolla is 

 white or pale purjjle, 6-8 inches long, and the limb often 4 inches in diameter. The 5 points 

 of the limb are sometimes produced into subulate processes, and there are intermediate folds 

 which are often rather acute, but not running out into a distinct tooth. It may be a distinct 

 species from D. Metel.

 Hook. & Am. Hot. Beechey, p. 153. Salinas river ; November. Common in southern Cali- 

 fornia and eastward to the Rio Grande. The plant is an annual. 



AscLEPiAS TBBEROSA, Linn. Eio Mimbres ; August. A narrow leaved form of the plant. 



Fraxinus velutina, Torr. in Emory's Rep. p. 149. On the San Pedro river of the Gila ; also 

 abundant on the Rio Grande and some of its tributaries. Variable in the pubescence of the 

 leaves. It sometimes attains the height of 30 feet. 



Menodora scabra. Gray in Sill. Journ. (2d ser.) 14, p. 44. Valley of Sauz; August. A low 

 plant with a shrubby base and yellow flowers, well characterized by Dr. Gray. — (Tab. VII.) 



Obione canesoens, 3Ioq. Ghenop., p)- 74 ; Torr. in Sifgreaves' Rep., p. 169. Santa Cruz valley; 

 August, (fem. ;) Cariso creek, (mas.) A variety with narrow leaves and small toothed bracts. 



Chenopodina linearis, Moq. in DC. Prodr. 13, pars 2, pt. 164, (in part.) Salsola linearis, 

 Ell. 8k. \,p. 322. S. Salsa? Michx. Fl. \,p. 74. On the Gila river ; June. This is, with 

 little doubt, Elliott's plant, and also the common species of the Atlantic salt marshes. It is an 

 annual, throwing up several erect branches from the base. Moquin has included two species in 

 his C. linearis ; one a shrubby plant, which may be called C. Moquini, and is C. linearis, Torr. 

 in Stan.shury' s Repiort, p. 394. 



Chenopodium AJU3R0SI0IDES, Linn. ; Moq. I. c. Banks of the Salinas river ; November. Proba-

MiRABiLis LONGiFLORUS, Linn.; Moquin in DC. Prodr. 13, pars 2, p. 428. San Pedro river 

 of the Gila ; July. Differs from the Moquin's description in not being " viscidly pubescent." 

 The lobes of the involucrum also are not linear, but lanceolate, and the tube of the perigonium is 

 pubescent. It is the same plant as 1702 of Wright's New Mexican collection.
