and somewhat scarious, all more or less pubescent (the inner 

 ones chiefly so at the tips), the outer ones often very much so 

 (even hirsute) and more or less glandular : heads many- 

 flowered, with a flat receptacle, and very long and slender 

 corolla-tubes with very minute lobes (if any) : achenes pubes- 

 cent, with scanty but long and conspicuous, very minutely 

 barbed soft white pappus. — Laguna Amatitlan, Depart. Ama- 

 titlan, alt. 3900 ft., March, 1890 {J. D. S. 2893). A species 

 remarkable in its leaf characters and very long and slender 

 corolla tube. 



Eupatorium ftftfaelense n. sp. — A small shrub, glabrous 

 or minutely pubescent : leaves opposite, rather long petioled, 

 ovate to lance-ovate, acute or acuminate, from crenate-serrate 

 to minutely so or even entire, 3 to 7.5 cm. long, 2.5 to 8.5 

 cm. wide (but the numerous specimens show only the leaves 

 of the branchlets) : heads 9 to 18 mm. high, in loose or rather 

 compact cymose clusters, terminating opposite divergent 

 branchlets, the clusters becoming more compacted into a 

 thyrsoid inflorescence above : involucral bracts linear-oblong, 

 often purplish, acute or obtuse, in about 3 unequal lax rows. 

 about half as long as the head, striate-nerved below, more or 

 less pubescent and glandular (especially the outer ones), all 

 with ciliate margins : heads 35 to 45-flowered, with a flattish 

 or slightly convex receptacle and glabrous corolla : achenes 

 scabrous-puberulent on the ribs, with conspicuous and bar- 

 bellate white pappus. — San Rafael, Depart. X-icatepequez,

EUPATORIUM POPUUFOI.hm IIBK, — This species seems 

 to be very variable in the size of its leaves and flower clusters. 

 Specimens from Laguna Amatitlan (J. D. S. 2400) are reed- 

 like in habit, becoming 18 feet high, with leaves a foot or 

 more long, compact thyrsoid panicles over a foot long and 

 broad, and uniformly 11 -flowered heads. Specimens from 

 Cuyuta, Depart. Escuintla (?. D. S. 2399), are 12 feet high, 

 with leaves not half as large, flower clusters onh 5 or *> inches 

 long and 3 or 4 broad, and uniformly 9-flowered heads. 



EUPATORIUM TUerckheimii Klatt. — Specimens from Pan- 



samala (Turckheim 1342) show broader leaves than the type. 



They are ovate and long-acuminate, often nearly 2 inche 

 broad.
