between Panixtlalmaca and Juquila, alt. 923 m., Feb. 26, 1895 (E. W. 

 Nelson, no. 2391) ; in oak- and pine-woods, San Carlos, Yauhtepec, 

 Jan. 5, 189G, and in mountain-woods between San Carlos and San 

 Bartolo, Jan. 6, 1896 (C. & E. Sder, nos. 1765, 1655); previously 

 collected at San Bartolo by Liebmann (no. 399), wbose specimen has 

 been referred by Dr. Klatt to B. hebecarpa, Gray. The present species, 

 however, differs from that as from the other related species in its glomer- 

 ulate heads and barely scarious involucre. 



Xanthocephalum megalocephalum. Perennial from slender 

 running rootstock : stem glabrous, glutinous, 3 or 4 dm. high, bearing 

 3 or 4 large solitary heads at the tips of long branches : leaves entire, 

 resinous-punctate, the lower spatulate and petioled, about 1 dm. long, 

 the upper lanceolate, sessile and shorter : involucre broad-hemispherical, 

 10 or 12 mm. high; the outer bracts lanceolate, witli herbaceous tips, 

 the inner oblong and blunt, mostly chartaceous : rays oblanceolate, blunt, 

 2 cm. long : achenes glabrous; pappus a crown of minute pales. — Chi- 

 huahua, Mt. Mohinora, Sept. 1, 1898 (E. W. Nelson, no. 4890); 

 Sierra Madre near Guachochi, alt. 2,100 m., Sept. 27, 1898 (E. A. 

 Goldman, no. 174). Related to X. Alamanl, Benth. & Hook., but 

 much larger throughout. 



Bigelowia Nelsonii. Shrub with rough dark gray bark; brandies 

 rigid and ascending, conspicuously glandular-punctate: leaves crowded, 

 linear, submucronate, conspicuously glandular-dotted, 0.5 to 1.5 cm. 

 long: heads solitary, subsessile at tips of short lateral leafy branches: 

 involucre 1 cm. broad, many-flowered, the 3 series of glandular bracts 

 thin, linear-attenuate: achenes long-silky. — CHIHUAHUA, in the Siena 

 Madre, Sept. 29, 1899 (E. W. Nelson, no. 6494). Resembling B. brachy- 

 lepis, Gray, but with much broader heads, and thinner attenuate involu- 

 cral bracts. 



Solidago Pringlei. Stem puberulent or minutely pilose, with few 

 ascending branches, very leafy: leaves linear or elongate-lanceolate, 

 narrowed below to a slender sub-petiolar base, and above to an acumi- 

 nate tip, 0.5 to 1.3 dm. long, 3 to 7 mm. wide, the midnerve prominent, 

 and two lateral ones sometimes apparent, finely appressed-serrulate or 

 subentire, with ciliate margins, puberulous above, finely pilose beneath : 

 panicles elongate, narrow, 1 to 1.5 dm. long, 2 or 3 cm. broad, secund, 

 the tips slightly recurved: involucre 4 mm. high; bracts glabrous, 

 linear, the outer acutish, the inner blunt: achenes pubescent. —
