Michoacan: volcanic hills, Monte Leon, 21 August, 1902, C. G. Pringle, 
no. 8687 (hb. Gr.). 
Evrnors1a Cumpr, Boiss. Cent. Euph. 16, and in DC. Prodr, xv. 
2, 48. Specimens agreeing in all details with this species, except that the 
glands of the involucre are either minutely appendaged or with the appen- 
dage wanting, were collected by Messrs. C. Conzatti and V. Gonzalez in 
the State of Oaxaca, Mexico, altitude 1900 m. July-August, 1900, 
no. 1040 (hb. Gr.). 
Euphorbia (§ Hypericifoliz) rubida. An herbaceous perennial : 
stems several, slender, 1.5 to 2.5 dm. long, ascending from a stout ligne- 
ous base, somewhat dichotomously branched, terete, reddish, crisp-puberu- 
lent: leaves opposite, short-petiolate, oblong, 5 to 23 mm. long, 2 to 8 
mm, broad, rounded at the apex, sharply serrulate, oblique and subcor- 
date at the base, sparingly pubescent on both surfaces with fine spread- 
ing hairs, often reddish, especially beneath ; petioles 1 to 2 mm. long: 
inflorescence terminating the stem and branches in rather close cymules: 
involucre small, 1 to 1.5 mm. high ; glands 4, bearing narrow crenate- 
margined appendages, these as well as the involucre mostly deep red in 
color: capsule obtusely triangular, 2 mm. long, equally broad, pubescent 
with somewhat spreading crisp-pilose hairs: seeds oblong-ovate, 1 mm. 
long, subquadrangular, grayish, slightly rugulose on the surfaces. — 
Mexico. State of Mexico: dry ledges, Tultenango Cafion, 9 October, 
1902, C. G. Pringle, no. 8673 (hb. Gr.). 
E. rubida is perhaps most closely related to E. Presli’, Guss., but dif- 
‘fers in having a distinctly perennial base, and in the pubescent character 
of the capsule. 
CurHEA xQuIPETALA, Cay., var. epilosa. Stems short-pubescent 
along decussating lines, not pilose-hispid. —Mexico. State of Puebla: 
on hills near Amozoc, altitude 2500 m., 10 September, 1901, 0. G. 
Pringle, no. 9628 (hb. Gr.). The variety epilosa differs from typical 
forms of the species in the absence of the purplish pilose-hispid hairs 
Commonly found on the stem. 
Erythrea micrantha. An erect, much-branched annual, 4 to 5 
dm, high, glabrous throughout: stem and branches somewhat 4-angled : 
leaves sessile; the lower. oblong-elliptic, 2 cm. long, 6 to 7 mm. broad, 
obtuse, entire, 8-nerved; the upper leaves similar or slightly spatulate, 
gradually reduced on the stem above: inflorescence terminating the di- 
chotomously branched stem and branches in a compound cyme: pedicels
