GREENMAN. — MEXICAN PHANEROGAMS. 575 



Dr. Rose ia the Sierra Madre, State of Tepic, nos. 1984, 3418. The 

 following supplementary characters may be appended : stems herbaceous 

 from a thick perennial base, 5 to 6 dm. high, simple or sparingly branched : 

 leaves usually alternate, not unfrequently opposite or at least subopposite. 

 E. leptodictyon closely resembles E. strictum, Gray, but may be distin- 

 guished readily from it by the fewer broader and more blunt bracts of the 

 involucre, and by the larger flowers. 



Grindelia glandulosa. Apparently biennial : root somewhat ob- 

 conical : stems subcespitose, erect, simple or sparingly branched, 2 to 3 dm. 

 high, glandular-pubescent with spreading hairs intermixed : basal leaves 

 spatulate, attenuate at the base, including the petiole G to 10 cm. long, 

 1 cm. or less in breadth ; stem leaves narrowly oblong or oblong-lance- 

 olate, slightly broadened at the sessile subclasping base, acute, regularly 

 and rather closely serrate, glandular-pubescent upon either surface, 2.5 to 



5 cm. long, 6 to 10 mm. wide; the uppermost leaves gradually reduced 

 and more or less acuminate : heads terminating the stems, solitary, ex- 

 cluding the rays 1.5 to 2 cm. in diameter; involucral scales strongly 

 imbricated, purplish, lanceolate, acuminate, terminated by an acutish 

 glandular-viscid tip; margins thin, purplish, suberose, glandular-ciliate, 

 the outer somewhat narrower: ray-flowers 20 to 35; ligules oblong- 

 spatulate, including the tubular portion nearly 2 cm. long : pappus usu- 

 ally bisetose, rarely trisetose or sometimes with a single awn, fugaceous : 

 achenes smooth. — Collected by C. G. Pringle in wet meadows of the 

 Sierra de Pachuca, State of Hidalgo, altitude 3,000 m., 13 August, 1898., 

 no. 6962. Seemingly a very distinct species, readily recognized by the 

 glandular character of the pubescence throughout the entire plant. 



Baccharis macrocephala, Sen. Bip. in herb. Gray. Perennial, 

 glabrous throughout: stems somewhat striated, covered with a grayish 

 bark : leaves scattered, sessile, spatulate-lanceolate, 2 to 3 cm. long, 3 to 



6 mm. broad, acute, often with a sharply recurved apex, entire and usually 

 hispidulous on the margins or with a few remote horizontally spreading 

 teeth near the apex, glandular-dotted on either surface and more or less 

 visc'.^ 1-3-nerved, the leaves of the flowering branches much smaller and 

 more or less squarrose-imbricated : inflorescence paniculate-virgate, leafy : 

 heads terminating the branches of the inflorescence, those of the fertile 

 plant nearly or quite 1.5 cm. high, many(90-100)-flowered : involucral 

 scales unequal, 6-7-seriate, imbricated, lance-linear with a dark green 

 midnerve, acute, glabrous, margins scarious and often slightly erose, the 

 inner about 7 mm. long, the outer shorter : pappus white or slightly tawny, 

 nearly or quite 1 cm. in length ; achenes glabrous : heads of the staminate
