DEC. 1907. SPERMATOPHYTES FROM MEXICO GREENMAN. 267 



Baccharis Kellermanii Greenman, sp. nov. 



Stem terete, sulcate, hirtellous-puberulent with crisp sordid 

 hairs: leaves elliptic-lanceolate to oblanceolate, i to 3.5 cm. 

 long, 2 to 8 mm. broad, acute or obtuse, sharply dentate with 

 unequal and somewhat spreading teeth, narrowed at the base 

 into a short petiole, at first slightly puberulent above but soon 

 becoming glabrous, persistently hirtellous-pubescent beneath, 

 subtrinervate and rather prominently reticulate-veined: in- 

 florescence a terminal subcorymbose cyme: heads of the pistil- 

 late plant numerous, 6 to 7 mm. high: involucre subcampanu- 

 late; bracts of the involucre unequal, 4-5-seriate, linear-ob-long, 

 obtuse or rounded at the tip, more or less purplish on the 

 back and ciliate towards the apex, the outermost shortest: 

 flowers 18 to 24; pappus about 4 mm. long, slightly tawny, 

 exceeding the slender corolla- tube : mature achenes 1.5 mm. 

 long, glabrous: staminate plant not seen. GUATEMALA. De- 

 partment of Solala: Volcano of Atitlan, 16 February, 1906, 

 W. A. Kellerman, no. 5356 (hb. Field Mus.). In leaf-outline 

 Baccharis Kellermanii suggests B. thesioides HBK., but the 

 two species are amply distinct in habit, inflorescence, involucral 

 details, and in the character of the surface of stem and leaves. 



Gnaphalium brachyphyllum Greenman, sp. nov. 



An herbaceous perennial, lanate-tomentose throughout: stems 

 several, erect or nearly so, from a ligneous base, i to 2 dm. high, 

 slender, leafy: leaves linear-oblong or slightly oblanceolate, 

 0.5 to 1.5 cm. long, i to 4 mm. broad, obtuse, entire, slightly 

 repand-margined, sessile and semiamplexicaul, densely lanate- 

 tomentose on both surfaces : inflorescence terminating the stems 

 in rather dense cymes: heads 4 to 5 mm. high: involucre sub- 

 campanulate, tomentose at the base otherwise essentially 

 glabrous; bracts of the involucre 3-4-seriate, pale stramineous, 

 the outer ovate and about 3 mm. long, the inner linear-lanceolate, 

 3.5 to 4 mm. long, greenish at the base especially along the 

 median line: pistillate flowers numerous: perfect flowers 6 to 10: 

 pappus caducous: achenes glabrous, i mm. long, reddish. 

 GUATEMALA. Department of Quezaltenango : Cerro Quemada, 

 8 February, 1906, W. A. Kellerman, no. 5301 (hb. Field Mus.). 

 The numerous slender stems and short crowded leaves render 

 this species readily recognizable among all the other known 

 species of the genus. 



MELAMPODIUM KUNTHIANUM DC. Prodr. v. 519 (1836); Hemsl. 

 Biol. Cent.- Am. Bot. ii. 146 (1881); Rob. Proc. Am. Acad. 

 xxxvi. 460 (1901). 



To this little known species the writer refers specimens collected 

 on hillsides near Chavarillo, State of Vera Cruz, Mexico, 7 Sep- 

 tember, 1906, C. R. Barnes, C. J . Chamberlain & W. J. G. Land, 

 no. 8 (hb. Field Mus., and hb. University of Chicago). In all 

 essential characters these specimens agree with descriptions of 

 the above species. The leaves in our material, however, are
