Pringle, no. 7698 (lib. Gr.), distributed as '•' Stevia sallcifolia, Cav." 

 State of Mexico: Mt. Ixtaccihautl, altitude 3350 to 3650 m., 1903, 

 C. A. P/a-pHS, uo. 185 (hb. Gr. and hi). Brandegee). Mr. Pringle's 

 specimen above cited was referred to aS*. saUcifolia, Cav. to which 

 species S. reniicosa is evidently related, but from which it differs in 

 having smaller closely instead of remotely serrulate leaves ; moreover, 

 the leaves are not attenuate at both ends, and the lateral veins are barely 

 visible instead of conspicuous as in typical >S. saUcifolia. 



Carphochaete SchafFneri, n. sp. An herbaceous perennial : stems 

 usually several from a ligneous base, 3 to 4.5 dm. high, glabrous or 

 puberulent: leaves opposite, sessile, subamplexicaul, linear-lanceolate, 

 1 to 4 cm. long, 1 to 3.5 mm. broad, acute, entire, glabrous, glandular- 

 punctate : inflorescence loosely corymbose : heads 2.5 to 3 cm. long, 

 4-flowered : involucre 1.3 to 1.5 cm. high; bracts of the involucre lance- 

 olate and acute to lanceolate more or less abruptly narrowed at the apex 

 and submucronate-acute, externally as well as the peduncles glandular- 

 hirtellous : pappus of 6 to 8 elongated linear-lanceolate 1-nerved pale- 

 aceous aristae and 2 to 5 short oblong obtuse pales: corollas 1.5 to 1.7 

 cm. long, white with a purplish throat, glabrous: achenes 10 to 12 mm.

 (hb. Gr.), distributed as '-An Stevia triflora, DC"; region of San Luis 

 Potosi, altitude 1850 to 2465 m., Parry Sf Palmer, no. 329 (hb. Gr.), 

 The number here cited from Parry & Palmer's collection was referred 

 by Hemsley, Biol. Cent. -Am. Bot. ii. 108, to Carphochaete Grahami, 

 A. Gr. from which species C. Schaffneri is easily distinguished by the 

 narrower acute leaves and the more lanceolate glandulai--hirtellous 

 unciliated involucral bracts. 



Brickellia megalodonta, n. sp. Stem terete, green or purplish, 

 pubescent : leaves opposite, petiolate, triangular-ovate to triangular-lance- 

 olate, 3 to 7 cm. long, 1.5 to 5 cm. broad, acuminate, acute, unequally 

 and coarse dentate, subcordate to somewhat cuueate at the base, 

 3-nerved, olive-green and sparingly pubescent above, paler ard pubes- 

 cent on the nerves beneath : inflorescence a terminal somewhat leafy 

 paniculate cyme ; peduncles 2.5 cm. or less in length, pilose-pubescent 

 and with glandular hairs intermixed: heads 12 to 13 mm. high, about 

 15-flowered: involucral bracts imbricated, 4-5-seriate, lance-acuminate, 

 gradually narrowed to the tip, conspicuously nerved, pale-green, often 

 tinged with purple ; the outer bracts shorter than the inner : pappus
