GREENMAN. — NEW ANGIOSPERMS FROM MEXICO. 83 



Mexico. State of Chiliuahua : Hacienda, San Miguel near Batopilas, 

 September, 1885, Dr. Edward Palmer, no. 201 (lib. Gr.). State of 

 Michoacan: volcanic hills, Monte Leon, 21 August, 1902, G. G. Pringle, 

 no. 8G87 (hb. Gr.). 



Euphorbia Cumbr^, 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 witli 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 (§ Hypericifoliee) 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- 

 raargined 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 Canon, 9 October, 

 1902, C. G. Pringle, no. 8673 (hb. Gr.). 



E. rubida is perhaps most closely related to E. Preslii, Guss., but dif- 

 fers in having a distinctly perennial base, and in the pubescent character 

 of the capsule. 



Cuphea ^quipetala, Cav., 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, C. G. 

 Pringle, no. 9628 (hb. Gr.). The variety ejnlosa differs from typical 

 forms of the species in the absence of the purplish pilose-hispid hairs 

 commonly found on the stem. 



Erythraea 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, 3-nerved ; the upper leaves similar or slightly sj^atulate, 

 gradually reduced on the stem above : inflorescence terminating the di- 

 chotomously branched stem and branches in a com^jound cyme : pedicels
