EUPATORIUMS OF PERU. 75 



broadest about a sixth of the length above the entire rather rapidly 

 narrowed base, gradually attenuate to an acutish tip, about 3 cm. 

 long, 7-8 mm. wide, thiekish-membranaceous and of rather firm tex- 

 ture, 3-ribbed from near the base, serrate from the broadest part to 

 the tip, teeth about 8 on each side slightly curved outward, the lowest 

 narrow and often slightly longer than the rest; petiole about 2 mm, 

 long; corymb compound, many-headed, round-topped, rather dense, 

 6-9 cm. in diameter, leaf y-bracted ; heads sessile or short-pedicelled, 

 about 4-flowered, 4 mm. long; corollas white, glabrous, slightly 

 enlarged upward, fragrant; style-branches filiform, slightly thickened 

 at the summit; pappus-bristles hispid-pubescent. — Nov. Gen. et 

 Spec. iv. 125 (1820). Ophryosponts chiica (HBK.) Hieron. in Engl. 

 Bot. Jahrb. xxii. 706 (1897). — Cajamarca: at the base of Mt. Sta. 

 Polonia, near the city of Cajamarca, Humboldt & Bonpland, no. 3682 

 (Par., phot. Gr., Berl., phot. Gr.). 



This and the tw^o following species are very closely related and with 

 the Bolivian E. eleuthcrauthcrum Rusby form a group doubtfully 

 intermediate between Eupatorium and Ophryosporus. Their final 

 disposition must await better and far more copious material than is 

 yet available. 



60. E. AFFiNE HBK. Glabrous shrub, closely resembling the 

 preceding; differing chiefly in its larger leaves (4 cm. long and 1.6 cm. 

 wide) and longer petioles (8-10 mm. in length), also in its more loosely 

 branched panicle, and 5-6-flowered heads of somewhat greater size 

 (6 mm. long).— Nov. Gen. et Spec. iv. 126 (1820). — Cajamarca: 

 thought to have been collected with the preceding, Humboldt & 

 Bonpland (Par., phot. Gr.). 



61. E. HEFT ANTRUM Sch. Bip. Shrub, closely related to the two 

 preceding, but the young branches and peduncles glandular-pubescent; 

 leaves lanceolate or ovate-lanceolate, 1.5-2.5 cm. long, 5-12 mm. 

 wide, acute at the apex, varying from obtuse to attenuate at the base, 

 glandular-puberulent on both surfaces; petiole short and pubescent; 

 heads in densish corymbs, about 7-flowered; involucral scales 7-8, 

 subequal, linear, acutish. — Bonplandia, iv. 54 (1856), without 

 descript. ; AYedd. Chlor. And. i. 217 (1857), w^here first described;
