the uppermost short-petioled: heads 4 to 7 mm. high, numerous 

 in a usually broad and ample leafy panicle, with white flowers: 

 involucral bracts narrowly oblong, acute or acuminate, in about 

 two nearly equal rows, thickened and conspicuously striate- 

 nerved below, thinner and sometimes almost scarious at tip 

 (especially the inner ones, which are also more decidedly 

 acuminate or even mucronate-tipped), the outer ones more or 

 less hirsute (often densely so), the inner ones glabrous or 

 chiefly pubescent at tip : heads 40 to 50-flowered, with a flat 

 or slightly convex receptacle and corolla-lobes bearded exter- 

 nally: achenes pubescent on the ribs, with scanty and barbel- 

 late pappus.— Aceituna, Depart. Guatemala, alt. 4600 ft., 

 Feb. 1889 (J. D. S. 2374); Coban, Depart. Alta Verapaz, alt. 

 4300 ft., April, 1889 (J. D. S. 10i>3) ; Sarnac, Depart. Alta 

 Verapaz, alt. 4(500 ft., April, 1889 [J. D. S. 1602); Volcan de 

 Agua, Depart. Zacatepequez, alt. 9500 ft.. April, 189<' 

 {J. D. S. 2329); Guatemala, Depart. Guatemala, alt. 5000 ft., 

 Feb., 1890 (J.D. S. 2365).— This species seems closely re- 

 lated to E. ciliatum Less. , to which it was referred by Hems- 

 ley {Bourgeau 1927) and John Donnell Smith (Turckheim 

 407, in 1887); but E. ciliatum has 18 to 22 flowers in a head 

 and a glabrous corolla, while E. Donnell- Smitkii has 40 to 50 

 flowers in a head and a bearded corolla. 



Var. parvifolium n. var.— Much smoother, with smaller 

 leaves, and but 20 to 35 flowers in a head. — Duenas, Depart. 

 Zacatepequez, alt. 5000 ft., April, 1890 {% D. S. 2333). 



EUPATORIUM AZUREUM DC. .'—Apparently a form of this 

 species was collected on Volcan de Agua, Depart. Zacatepe- 

 quez, alt. 9000 ft., April, 1890 (J.D. S. 2326), in which the 

 heads are but 12 to 16-flowered. 



Eupatorium lyratum n. sp.— A stout apparently low 

 branching perennial herb, softly pubescent throughout (the 

 stem often even hirsute and more or less glandular) : leaves 

 alternate the lower ones obovate, lyrately-pinnatifid and 

 petioled 5 to 9 cm. long, 2.5 to 4 cm. wide, gradually be- 

 coming less lyrate. irregularly toothed, sessile and even 

 aunculate-clasping above, the uppermost ones (in the inflo- 

 rescence) merely ovate (acute) and slightly toothed or entire: 

 heads about 6 mm. high, rather few in a very loose irregular 

 leafy panicle with white flowers: involucral bracts linear- 

 lanceolate to linear, acuminate, very lax in 3 or more unequal 

 rows (some of them exceeding the head), the inner ones linear
