few. Mr. Thurber informs us that this plant is called Yerba de la Golondrina in Sonora. The 
Mexicans believe it to be a certain cure for the bite of a rattlesnake and other poisonous animals 
The bruised fresh plant or the dried, steeped in wine, is applied to the wound. A tincture of 
the plant is sometimes kept in the apothecarys’ shops of that country. According to Dr. Gregg, 
the name Golondrina is applied to all the prostrate Euphorbie. 
EUPHORBIA INJEQUILATERA, Sonder in Linnea, 23, р. 105. I cannot distinguish from this plant 
of the Cape of Good Hope a species of the plains of Nebraska, Kansas, and Texas, and which 
extends into New Mexico, California, and Oregon. There it has been collected since the 
explorations of Nicollet and Frémont by almost every traveller, (e. g., Fendler, 191, 795, 803; 
Wright, 666, 1823, (in part,) 1846.) The same plant has been sent from Florida by Blodgett 
and Chapman, is found on the West India Islands, is undoubtedly the E. Nilagirica, Mig., of 
India, and has also been observed in New Holland ; but it seems unknown in other States east 
of the Mississippi. 
EUPHORBIA GLYPTOSPERMA (nov. spec.): erecto patula seu demum decumbens ; foliis e basi 
valde obliqua (latere inferiore producta) æquilatis oblongis s. oblongo-linearibus obtusis versus 
apicem subserratis s. integriusculus ; stipulis setaceis laciniatis, anthodiis alaribus demum in 
glomerulos laxos laterales confertis ; appendiculis brevibus integris seu crenatis ; stylis brevibus 
apice bilobis, stigmatibus subglobosis; seminibus ovatis argute rugosis ad angulos acutos 
crenatis. I. polygonifolia, Hook. Fl. Bor. Am. fide spec. auctoris non Linn. 
B. TENERRIMA : foliis parvulis angustis apice vix crenulatis ; involucri minuti glandulis vix 
seu non appendiculatis. On the Rio Grande; also on the Arkansas, and extending to the 
upper Missouri, (No. 1853, 1855, and 1856, Wright.) From a few inches to a foot high. The 
larger northern forms have leaves 3 to 6 lines long and 1 to 2 lines wide. In ñ the leaves are 
1 to 3 lines long and 4 to 1 line wide; involucrum in the latter only 0.3 line long. Seed very 
sharply cross-ribbed, similar to that of Æ. prostrata, and notched at the angles. 
EUPHORBIA STICTOSPORA (nov. spec.): erecto-patula, foliis e basi obliqua subcordata orbiculatis 
seu ovatis argute serratis supra subnudis; stipulis subulatis ciliatis; glomerulis lateralibus 
sessilibus ; glandulis angustis appendiculatis ; stylis ovario pubero brevioribus patulis indivisis ; 
stigmatibus 3 capitatis; capsula puberula; seminibus angustis acute angulatis exsculpto- 
punctatis. From Kansas (Fendler, 798,) to Santa Fé (Fendler, 797) and Doña Ana, (Wright. 
.59,) New Mexico, and Corallitas, Chihuahua ; Thurber. Stem 3-6 inches high. Leaves 2-4 
lines long ; apparently near Z. prostrata, but styles and seeds very different. 
EUPHORBIA PROSTRATA, Ait. This variable and often mistaken species is found from western 
Louisiana (Dr. Hale) to Texas ; (Lindheimer, 533 ;) (Berlandier, 1100, 2530 ;) (Wright, 1848 
in part, 1855 in part.) It seems to be a common plant in the West India islands, Mexico, and 
South America. It occurs in Africa and India. Euphorbia tenella, H. B. K., and E. callibri- 
choides, H. B. K., are forms of the same species, which can always be recognized by the ciliate 
angles of the capsule and the sharply rugose seeds, notched at the angles. | 
“Есрновв prorca, H. B. К. (E. anceps, Benth. E. callibrichoides; Schauer, ete.,) a common 
and very variable plant of Mexico, Central America, and the West India islands, has been 
collected by Dr. Antisell on the upper Rio Grande. | е 
; Var.? INDIVISA, distinguished by the annual root, the less coriaceous, less oblique and less 
distichous leaves, the more scattered involucra and the undivided styles; has been found near the 
ipic. New Mexico, by Mr. Wright, (No. 1845) and in Sonora by Mr. Thurber,
